The tube expansion calculator on this page computes the two critical quality parameters for heat exchanger tube rolling: percentage wall thinning and percentage expansion. These are the standard measurements used to verify that a mechanical tube-to-tubesheet joint has been rolled to the correct degree — tight enough to be leak-proof, but not so heavily rolled that the tube wall is excessively thinned and weakened. Enter the tube dimensions before and after rolling, along with the tubesheet hole diameter; the calculator returns both percentages with automatic comparison against TEMA and ASME acceptance limits, displayed as live status gauges.

Tube rolling is one of the most skill-sensitive operations in heat exchanger fabrication. A roller expansion that is 1 to 2 percent short of target produces a joint that may pass the initial hydrostatic test but leak under thermal cycling. An expansion 3 to 4 percent over target may still hold pressure but has permanently weakened the tube wall at the most critical cross-section. This article explains the physics of roller expansion, the formulas for both quality parameters, the TEMA and ASME acceptance criteria, and the practical procedure for setting up a roller expansion operation in a fabrication shop.

The Roller Expansion Method

Roller expansion is the standard method for creating a mechanical tube-to-tubesheet joint in shell-and-tube heat exchangers. A tube roller (also called a tube expander) is a tool consisting of a tapered mandrel and three to five hardened steel rolls arranged around it. When the mandrel is driven forward by a torque-controlled motor, the tapered profile forces the rolls outward, pressing the tube wall against the tubesheet hole wall. The tube material deforms plastically, filling the hole and creating a tight interference fit between the tube OD and the tubesheet hole wall.

The joint strength depends on the interference fit achieved — the residual compressive stress between the tube OD and tubesheet hole. This is directly related to how far the tube wall has been expanded outward, expressed as the percentage expansion of the tube bore diameter. Simultaneously, the tube wall thins as the material is stretched circumferentially, which is expressed as percentage thinning. Both must be controlled within specified limits to produce a joint that is both leak-tight and mechanically sound.

Scope of This Calculator: This calculator covers mechanical roller expansion of tubes into tubesheets — the most common tube-to-tubesheet attachment method in shell-and-tube heat exchangers. Both percentage expansion (bore diameter increase) and percentage thinning (wall thickness reduction) are calculated and compared against TEMA and ASME acceptance limits automatically. For welded tube-to-tubesheet joints, also refer to the ASME Section IX qualification requirements in the link grid below.
ASME and TEMA Code Scope: ASME Section VIII Division 1 paragraph UW-20 governs tube-to-tubesheet joints in pressure vessels and heat exchangers. For exchangers designed and fabricated to TEMA standards (Tubular Exchanger Manufacturers Association), the applicable TEMA class (R, C, or B) further defines the expansion requirements. WeldFabWorld’s tubesheet qualification guide covers the full ASME Section IX requirements for tube-to-tubesheet weld and expansion procedure qualification.

Percentage Thinning and Percentage Expansion Formulas

Percentage Expansion

Percentage expansion measures the increase in tube inside diameter as a fraction of the original inside diameter:

Percentage Expansion Formula: % Expansion = ((ID_after − ID_before) / ID_before) × 100
Where:
ID_before = tube inside diameter before expansion = OD − 2t
ID_after = tube inside diameter after expansion (measured with tube caliper)

Equivalent formula using tubesheet hole diameter: % Expansion = ((ID_after − ID_before) / ID_before) × 100 Note: ID_after is measured, NOT assumed equal to tubesheet hole diameter.
The tube springs back slightly after the roller is withdrawn (elastic springback),
so ID_after < tubesheet hole diameter after expansion is complete.

Percentage Thinning

Percentage thinning measures the reduction in tube wall thickness as a fraction of the original wall thickness:

Percentage Thinning Formula: % Thinning = ((t_before − t_after) / t_before) × 100
Where:
t_before = original tube wall thickness (nominal, before expansion)
t_after = tube wall thickness after expansion (calculated or measured)

Calculating t_after from measured ID_after (volume conservation approximation): t_after = (tubesheet_hole_diameter − ID_after) / 2 This assumes the tube OD is pressed hard against the tubesheet hole wall after expansion.
For a first estimate: t_after ≈ t_before × (1 − % Expansion / 100) The exact relationship requires a volume conservation calculation (see below).

Relationship Between Thinning and Expansion

Volume Conservation Relationship (incompressible plasticity): A_wall_before = A_wall_after (cross-sectional metal area is conserved) π/4 × (OD² − ID_before²) = π/4 × (D_hole² − ID_after²) This gives the theoretical ID_after for a fully-expressed expansion against the tubesheet hole.

Solving for ID_after (theoretical maximum, ignoring springback): ID_after_max = √(D_hole² − OD² + ID_before²) Actual ID_after is slightly less than this due to elastic springback of both tube and tubesheet.
Tube-to-Tubesheet Cross-Section: Before vs After Expansion BEFORE ROLLING Gap (clearance) t ID_before AFTER ROLLING t_after (thinner) ID_after (larger) D_hole % Expansion = (ID_after − ID_before) / ID_before × 100 % Thinning = (t_before − t_after) / t_before × 100 t_after = (D_hole − ID_after) / 2 | TEMA target: 5–8% expansion, max 8% thinning
Figure 1 — Cross-section of a tube inside a tubesheet hole before rolling (left: clearance gap visible, original wall thickness t, inside diameter ID_before) and after rolling (right: tube wall pressed against hole wall, thinned wall t_after, expanded bore ID_after). Percentage expansion measures the ID increase; percentage thinning measures the wall thickness reduction.

Acceptance Limits — TEMA, ASME, and Project Standards

Both percentage expansion and percentage thinning must fall within specified acceptance windows for the joint to be accepted. Under-expansion fails to create a reliable leak-tight joint; over-expansion causes excessive thinning that weakens the tube. The following table summarises industry-standard limits:

Standard Class / Type Min % Expansion Target % Expansion Max % Expansion Max % Thinning
TEMA Class R (Petrochemical) 3% 5–8% 8% 8%
TEMA Class C (General commercial) 3% 5–8% 8% 10%
TEMA Class B (Chemical) 3% 5–8% 8% 8%
ASME VIII UW-20 expanded-only 3% 5–8% 8% 8%
Common Project Specs Oil & Gas (typical ITP) 5% 6–7% 8% 8%
Common Project Specs High alloy / Ti / Cu-Ni 3% 4–6% 6% 6%
Project Specification Always Governs: The limits shown above are typical industry guidance. The actual limits applicable to your exchanger are those stated in the Inspection and Test Plan (ITP), the exchanger data sheet, or the fabrication specification. Always confirm limits with the responsible engineer before the first production tube is rolled. For first-off or qualification rolls, a mock-up test on scrap tube and tubesheet material is strongly recommended to calibrate the roller torque setting.

Worked Example — Step by Step

Design Data: Shell-and-tube heat exchanger, TEMA Class R. Tube: ASTM A179 seamless low-carbon steel, OD = 25.4 mm (1 inch), wall thickness t = 2.11 mm (BWG 14). Tubesheet hole diameter = 25.65 mm. After rolling, measured tube ID = 21.82 mm. Acceptance limits: 5 to 8% expansion, max 8% thinning.
Step 1 — Tube ID Before Expansion: ID_before = OD − 2t = 25.4 − 2×2.11 = 25.4 − 4.22 ID_before = 21.18 mm

Step 2 — Percentage Expansion: % Expansion = ((ID_after − ID_before) / ID_before) × 100 % Expansion = ((21.82 − 21.18) / 21.18) × 100 % Expansion = (0.64 / 21.18) × 100 % Expansion = 3.02% Check against limits: min 5% → BELOW MINIMUM — UNDER-ROLLED — re-roll required

Step 3 — Wall Thickness After (from tubesheet hole and measured ID): t_after = (D_hole − ID_after) / 2 = (25.65 − 21.82) / 2 t_after = 3.83 / 2 = 1.915 mm Note: this assumes tube OD is fully seated against tubesheet hole wall

Step 4 — Percentage Thinning: % Thinning = ((t_before − t_after) / t_before) × 100 % Thinning = ((2.11 − 1.915) / 2.11) × 100 % Thinning = (0.195 / 2.11) × 100 % Thinning = 9.24% Check against limit: max 8% → EXCEEDS LIMIT — Review required

Step 5 — Target ID for Correct Expansion (5–8% range): ID_target_min = ID_before × 1.05 = 21.18 × 1.05 = 22.24 mm ID_target_max = ID_before × 1.08 = 21.18 × 1.08 = 22.87 mm Target measured ID after rolling: 22.24 to 22.87 mm Current ID_after (21.82 mm) is below target minimum — tube must be re-rolled

This worked example illustrates a tube that was under-rolled — the expansion of 3.02% falls below the 5% minimum, meaning the joint is not sufficiently tight against the tubesheet hole wall. The tube must be re-rolled to bring the ID into the 22.24 to 22.87 mm range. Note that the percentage thinning calculation showing 9.24% is a consequence of the geometric assumption that the tube is seated against the hole wall — in practice, an under-rolled tube may not be fully seated, and the actual thinning may be less. Once correctly rolled to 5 to 8% expansion, the thinning should be recalculated from the new measured ID.

Tube Expansion Outcome Zones Percentage Expansion (%) 0 3 5 8 12 UNDER-ROLLED Leak risk < 5% expansion ACCEPTABLE 5–8% Tight joint low thinning OVER-ROLLED Excessive thinning > 8% expansion Tube may crack Min 5% Max 8% Worked example 3.02% — re-roll Thinning ↑ increases
Figure 2 — Tube expansion outcome zones. The acceptable window (green, 5 to 8% expansion for TEMA Class R/C) produces a tight, leak-proof joint with acceptable thinning. Under-rolling (red, below 5%) risks a leaking joint. Over-rolling (amber, above 8%) causes excessive wall thinning and may crack work-hardening alloys. The worked example point (3.02%) falls in the under-rolled zone and requires re-rolling.

Tube Materials and Expansion Considerations

Tube Material Common Spec Work Hardening Typical Expansion Target Special Precautions
Low-carbon steel ASTM A179 Low 5–8% None — most forgiving material
Carbon steel (seamless) ASTM A214 Low 5–8% Confirm wall thickness before rolling
Stainless 304 / 316 ASTM A213 TP304/316 Medium 5–7% Monitor torque; springback more significant
Duplex SS (2205) ASTM A789 S31803 Medium 4–6% Qualification roll mandatory; harder material
Copper-Nickel (90/10) ASTM B111 C70600 High 3–6% Risk of cracking if over-rolled; use calibrated torque
Admiralty Brass ASTM B111 C44300 High 3–5% Very sensitive to over-rolling; trial rolls essential
Titanium Grade 2 ASTM B338 Gr 2 Medium 3–6% High springback; final ID hard to predict — calibrate carefully
Alloy 825 / 625 ASTM B163 N08825 Medium-High 4–6% High strength; higher rolling force required; qualification mandatory

Tubesheet Hole Grooves

TEMA requires that tubesheet holes for Class R and Class B exchangers be machined with grooves to increase the mechanical strength of the tube-to-tubesheet joint. Grooves are circumferential channels machined into the tubesheet hole wall, typically 0.4 to 0.8 mm deep and 3 to 5 mm wide, at defined positions along the expansion length. When the tube is rolled, metal flows into the grooves, creating a mechanical interlock that significantly increases pull-out strength and resistance to leakage under pressure cycling.

TEMA Class Grooves Required? Number of Grooves Groove Depth Purpose
Class R (Petrochemical)Required2 minimum0.40 mm (1/64 in)Pull-out resistance, leak-tightness
Class C (General)Recommended1–20.40 mmJoint integrity improvement
Class B (Chemical)Required2 minimum0.40 mmPull-out resistance
Engineering Tip: The presence of tubesheet grooves slightly increases the measured percentage expansion compared to an ungrooved hole at the same roller torque setting, because the tube material flows into the grooves, locally increasing the ID measurement. When grooves are present, the ID measurement should be taken at the land areas (between grooves) rather than at groove locations for the most meaningful comparison against expansion limits. Some inspection plans require measurements at both groove and land locations.

Roller Expansion Procedure

A controlled rolling procedure is essential for consistent, repeatable joint quality. The procedure covers tool selection, torque setting, expansion sequence, and measurement protocol.

Step 1 — Tool Selection

Select a tube roller matched to the tube OD and wall thickness. The roller cage diameter must correspond to the tube ID. Using an undersized cage risks inadequate contact; an oversized cage cannot be inserted. For thin-walled tubes, a cage with more rolls (5-roll) distributes the forming force more evenly and reduces the risk of tube ovality.

Step 2 — Torque Setting Calibration

The torque limit on the roller motor is the primary control parameter. Before production rolling begins, a trial expansion must be performed on a sample tube of the same specification in a mock-up tubesheet of the same material and thickness. The torque is set to achieve the target percentage expansion (typically 5 to 8%), measured after each trial and adjusted until the target is consistently achieved. This calibration torque setting is recorded and used for all production rolling.

Step 3 — Expansion Sequence

In a multi-pass bundle, all tubes in a tubesheet should be expanded in a defined sequence — typically from the centre outward in a spiral or grid pattern — to distribute the tubesheet distortion evenly and avoid locking-up the tubesheet plate. Rolling all tubes on one side before the other can cause tubesheet bowing, which makes insertion of the remaining tubes difficult and can introduce differential stresses into the joint.

Step 4 — Measurement and Acceptance

After rolling, measure the tube ID using a calibrated tube caliper or internal micrometer. Record the measurement in the rolling log. Calculate percentage expansion and percentage thinning using the formulas on this page. Compare against the acceptance limits in the ITP. Any tube outside limits must be investigated — under-rolled tubes may be re-rolled to bring them into range; over-rolled tubes may require replacement depending on the severity and the applicable code.

Under-Rolling and Over-Rolling

Two failure modes are possible in tube rolling, each with different consequences and remedies:

Under-Rolling (Insufficient Expansion)

Under-rolling means the tube has not been expanded enough to seat firmly against the tubesheet hole wall. The residual interference fit is insufficient to develop the full joint strength and seal. The joint may pass the initial hydrostatic test at ambient temperature but fail under thermal cycling as the differential thermal expansion between the tube and tubesheet opens a micro-gap. Under-rolled tubes can be re-rolled by reinserting the roller and increasing the torque setting. However, re-rolling should be done carefully — the tube has already been work-hardened by the first rolling pass, and excessive re-rolling on work-hardening alloys (copper-nickel, admiralty brass) can cause cracking.

Over-Rolling (Excessive Expansion)

Over-rolling means the tube wall has been thinned beyond the acceptable limit. Once a tube is over-rolled, the thinning cannot be reversed. The excess thinning reduces the tube pressure rating at the joint location. Depending on the severity, the remedy may be to accept the tube if the thinned wall still meets the minimum required thickness for the design pressure (verified by calculation), or to replace the tube if the thinning is severe. For work-hardening alloys, over-rolling may have caused microscopic cracking at the knuckle zones — in these cases, PT (liquid penetrant testing) of the expanded zone should be performed before acceptance.

Caution on Re-Rolling: The maximum number of re-rolling passes must be specified in the rolling procedure and should be confirmed with the tube material supplier. For admiralty brass and Cu-Ni tubes, typically only one re-roll pass is permitted. For carbon steel and stainless steel, two re-roll passes are generally acceptable. Beyond these limits, the tube should be replaced rather than rolled again. Each re-roll further work-hardens the tube material and reduces the remaining ductility.

Welded and Expanded Joints

For critical applications — high-pressure, high-temperature, toxic or flammable fluids, or where leak-tightness under cycling loads is essential — ASME VIII and project specifications require a combination of mechanical expansion and welding. The two most common combined joint types are:

Strength weld plus light expansion: A full-penetration or partial-penetration weld is made between the tube end and the tubesheet face, providing the full structural load-carrying capacity. The expansion (typically 3 to 5%) is then performed to eliminate the annular gap between the tube OD and the tubesheet hole, reducing crevice corrosion and providing additional resistance to leakage. In this configuration, the weld carries the pressure load and the expansion is supplementary.

Seal weld plus full expansion: A light fillet seal weld is applied at the tube-tubesheet junction to prevent leakage, while the mechanical expansion carries the structural load. This configuration is less common but used where full-penetration welding is difficult (e.g., very thin tubes, dissimilar metals with problematic metallurgical compatibility).

ASME Section IX Qualification: Tube-to-tubesheet weld and expansion procedures must be qualified per ASME Section IX when the joints involve welding. The qualification test requires a mock-up assembly with the specified tube and tubesheet materials, the same weld procedure, and the same rolling procedure. Pull-out tests and, for welded joints, peel tests are performed on the completed qualification assembly. The qualified procedure is then used as the basis for production rolling and welding without further qualification unless essential variables change.

Practical Engineering Notes

Tubesheet Hole Tolerance and Its Effect on Expansion

The tubesheet hole diameter and its tolerance are specified on the exchanger drawing. TEMA gives standard hole dimensions for each tube OD, with the clearance (gap between tube OD and hole wall before rolling) typically 0.20 to 0.40 mm. A larger clearance requires more rolling to close the gap and seat the tube, increasing the risk of over-thinning before the target percentage expansion is reached. If the tubesheet holes are drilled oversize due to a tooling error, the rolling engineer should be notified before proceeding, as the torque calibration will need to be revised.

Tubesheet Material Effect on Joint Quality

The hardness of the tubesheet material relative to the tube material affects how the tube seats into the hole. For best joint quality, the tubesheet should be harder than the tube so that when the tube is expanded, the tube metal deforms plastically into the grooves rather than the tubesheet deforming. Carbon steel tubesheets with carbon steel tubes, or harder duplex stainless tubesheets with softer austenitic stainless tubes, satisfy this requirement. When soft tubesheet materials (e.g., naval brass tubesheet with copper-nickel tubes) are used, the interference fit may be less reliable and pull-out testing is more important.

Connection to Heat Exchanger Pressure Vessel Design

The tube expansion calculation presented here is specific to the tube-to-tubesheet joint. The broader pressure vessel design of the exchanger — shell thickness, channel covers, flanges, and nozzles — is governed by ASME VIII Div 1 and must be calculated using the tools covered in the rest of this B-series. The pressure vessel shell thickness calculator handles the exchanger shell. For nozzle connections on the channel or shell, the nozzle reinforcement calculator applies UG-37. For the tube material selection and weld procedure, see the welding consumable nomenclature guide and the mechanical testing guide for the applicable qualification tests.

Frequently Asked Questions

What is percentage expansion in heat exchanger tube rolling?
Percentage expansion measures how much the tube inside diameter has increased relative to the original inside diameter during roller expansion. Formula: % Expansion = ((ID_after − ID_before) / ID_before) × 100. TEMA standards typically specify a target range of 5 to 8 percent for most services. Expansion must be sufficient to create a tight interference fit between the tube OD and the tubesheet hole wall, but not so high that thinning exceeds the acceptance limit.
What is percentage thinning and why is it important?
Percentage thinning measures how much the tube wall has reduced in thickness: % Thinning = ((t_before − t_after) / t_before) × 100. Thinning occurs because the tube material stretches during expansion. Excessive thinning weakens the tube at the joint and may reduce its pressure rating below the design requirement. TEMA Class R and ASME UW-20 limit thinning to a maximum of 8 percent of the original wall thickness. The wall thickness after expansion is typically calculated as: t_after = (tubesheet hole OD − measured ID_after) / 2.
How is percentage thinning related to percentage expansion in tube rolling?
The two parameters are linked through conservation of metal volume. When the tube expands radially outward, the wall must thin to conserve the metal cross-sectional area. Higher expansion produces greater thinning. For most standard tube geometries in the 5 to 8% expansion range, the thinning percentage is roughly similar in magnitude to the expansion percentage. This is why the maximum thinning limit (8%) roughly corresponds to the maximum expansion limit (8%) for typical tube dimensions.
What are the TEMA standard limits for tube expansion?
For TEMA Class R (petrochemical) and Class B (chemical) exchangers, the target expansion is 5 to 8%, with a maximum thinning of 8%. For Class C (general commercial), the thinning limit is 10%. ASME Section VIII Div 1 UW-20 specifies 3 to 8% expansion with max 8% thinning for expanded-only joints. For high-alloy or work-hardening tube materials (Cu-Ni, titanium, admiralty brass), tighter limits of 3 to 6% expansion and 6% maximum thinning are common in project specifications. Always confirm limits from the exchanger data sheet and ITP.
What is the difference between under-rolling and over-rolling in tube expansion?
Under-rolling: the tube bore has not expanded enough (below 3 to 5% expansion). The tube OD is not fully seated against the tubesheet hole wall, leaving insufficient interference fit. The joint may leak under service conditions. Remedy: re-roll the tube. Over-rolling: the tube bore has expanded too far (above 8%). The tube wall is excessively thinned, weakening the tube at the joint. Severe over-rolling can crack work-hardening alloys. Over-rolling cannot be reversed. Remedy: verify the remaining wall thickness still meets the minimum required for design pressure; replace the tube if it does not.
Can tube expansion be used as the sole method of tube-to-tubesheet attachment?
Yes, under certain conditions per ASME Section VIII Div 1 UW-20. Expansion-only joints are acceptable for water coolers, feedwater heaters, and low-pressure utility exchangers. For critical services — high pressure, high temperature, toxic or flammable fluids, hydrogen service, or Category M service — a combination of strength or seal welding plus expansion is required. The welding procedure must be qualified per ASME Section IX, and the expansion procedure must also be qualified as part of the tube-to-tubesheet joint procedure.
What tube materials require special precautions during roller expansion?
Copper-nickel (90/10 and 70/30) and admiralty brass work-harden rapidly during cold rolling, making over-rolling a risk for cracking. Titanium tubes have significant elastic springback, making the final expanded diameter hard to predict without a calibration trial. Austenitic stainless and duplex stainless steels are also more sensitive than plain carbon steel. For all non-standard materials, trial expansions on sample tube sections in a representative tubesheet mock-up are strongly recommended before production rolling begins, to calibrate the roller torque and verify the target expansion range is achievable.
How is tube inside diameter after expansion measured in practice?
The post-expansion tube ID is measured using a calibrated tube caliper or internal micrometer inserted into the tube bore at the expanded zone. Measurements are taken in two perpendicular directions to check for ovality. In production, a statistically representative sample (often 10% of total tubes, or as specified in the ITP) is measured and recorded in the rolling log. Measurements at grooved zones and between grooves (lands) may differ; the ITP should specify which locations to measure. All results are checked against acceptance limits before the exchanger proceeds to the next stage.
What is the role of tubesheet hole grooves in tube expansion?
Tubesheet hole grooves are circumferential channels (typically 0.4 mm deep, 3 to 5 mm wide) machined into the hole wall. During rolling, tube material flows into the grooves, creating a mechanical interlock that significantly increases pull-out strength and leak-tightness. Grooves are mandatory for TEMA Class R and Class B exchangers. They also raise the measured percentage expansion at the groove location relative to the land areas, so measurements should be taken at land areas for consistency. The groove dimensions are specified in TEMA standards and on the tubesheet drawing.
