YOUR TUBE. YOUR RADIUS. YOUR FINISHED FIT.

Tube & Pipe Bending Services for Your Assembly Fit

Plan custom tube bending around your grade, outside diameter, wall thickness and final geometry. Review end positions, section condition and sample checks before production.

Start with 1 formed CAD model + 1 controlled 2D drawing.

3 Decisions Before Your First Bend

Define the requirements that affect your tooling, sample and finished fit.

01

Your tube

Grade, condition, outside size and wall.

02

Your geometry

Radius, straight lengths and bend planes.

03

Your acceptance

End positions, section limits and finish.

Custom Bent Tubing for Your Equipment

Select your part, then review the details that affect your assembly.

Plan Your Bent Tube Handles Around the Mounting Points

Mark the end positions, orientation and datums on your controlled drawing.

Your fitEnd locations, datums and mating parts.
Your bendCenterline radius, tangents and bend planes.
Your finishEnd condition and visible surfaces.

Geometry and manufacturing scope are confirmed during drawing review.

2 Size Systems. 1 Clear Specification.

Tube

Actual outside diameter or section size × wall thickness.

Pipe

Nominal size + schedule or wall; confirm actual outside diameter and applicable standard.

Confirm the Grade, Not Just the Metal

MaterialKey Points for Your Specification
Stainless SteelFor stainless steel tube bending, define grade, seam condition and visible-surface requirements.
AluminumFor aluminum tube bending, confirm alloy, temper and forming condition.
Carbon SteelFor carbon steel tube bending, specify grade, tube construction and final coating.

Material, section and tooling suitability are reviewed together. Square tube bending and rectangular tube bending also require the bend direction.

3 Different Decisions Behind Your Bend

FORMING ROUTE

Rotary Draw Tube Bending

A die controls the bend geometry; review outside size, wall and tooling.

INTERNAL SUPPORT

Mandrel Tube Bending

Internal support can help control section deformation; suitability depends on your tube.

MOTION CONTROL

CNC Tube Bending

Review feed, rotation and bend sequence for your complete geometry.

These terms are not interchangeable. Process, equipment and tooling availability are confirmed for your part.

Resolve 6 Risks Before Tooling

Use these tube bending design guidelines to define your finished geometry and acceptance.

Confirm Your Radius and Wall Together

Specify the tube bending centerline radius, not only the inside radius.

ILLUSTRATION ONLY — NOT A MINIMUM RADIUS OR EQUIPMENT RANGE

Outside diameter25 mmWall thickness1.5 mmCenterline radius75 mm
Bend ratio: 75 ÷ 25 = 3.0D

Wall factor: 25 ÷ 1.5 ≈ 16.7

These ratios describe this example only; they do not guarantee bendability. Material condition, tooling and acceptance limits need review.

4 Steps from Straight Stock to Your Finished Part

01

Cut & Prepare

Cut to length and prepare ends.

02

Bend & Check

Form the bends and check key dimensions.

03

Finish as Specified*

Deburr, clean or apply the agreed finish.

04

Inspect & Pack

Check dimensions, protect and identify parts.

* Secondary operations are included only when specified in your quote.

Check Both Ends, Not Only the Bend Angle

Agree the reference datums, measurement method and final-part limits.

Approve Your Part Before Repeat Production

Use prototype tube bending to review the geometry, tooling and measurement plan.

  • End positions and bend planes
  • Section shape, surface and specified wall checks
  • Fit with your mating parts

Fixtures, sampling and special tests are agreed for your project. Dimensional results alone do not establish pressure integrity.

Answers Before Your First Order

What is the minimum bend radius for tubing?

The minimum tube bend radius depends on outside size, wall, grade, condition and tooling. Agree section and final-fit limits; do not assume one radius fits every tube.

How much straight length is needed between tube bends?

Required tangent length depends on the clamp, bend die, support and sequence. Send the complete formed geometry; short tangents may need revised tooling or a geometry change.

How is tube bending ovality measured?

Agree the largest and smallest outside diameters at a defined section, the reference diameter and the formula before setting limits. Specify measurement locations and the finished-part state.

How much does custom tube bending cost?

Compare material, tooling and setup, bend count, handling, finishing and inspection at your trial, first-order and annual quantities. Use the same revision and acceptance scope for each quote.

What files are needed for a tube bending quote?

Send formed CAD and a controlled drawing showing material, outside size, wall, centerline radii, bend planes, tangents, end details, datums and inspection requirements. Add quantities, finish and required delivery.

How long does custom tube bending take?

Timing depends on stock availability, suitable tooling, setup, sample approval, finishing and order quantity. Request separate sample and production milestones for your drawing.
