Inspection and Tests
We inspect all lots of tubing before shipment to ensure that every aspect of the customer's order has been met.
Our in-house inspection and tests capabilities include:
Chemical Composition Test
Visual inspection
Dimensional inspection
Surface roughness testing
Eddy Current testing
Hydrostatic pressure testing
Destructive mechanical testing:
- Yield Strength
- Tensile Strength
- Elongation
- Hardness testing
- bending, flattening, and flaring
All shipments include a full Test Certificate showing all required test results and verifying compliance with the order requirements.
