Importers who work with certified makers, like Yuan Steel, can give you factory test certificates. These papers show each batch of pipe meets quality standards.
Compliance with 2026 Standards
In 2026, you must check suppliers follow new testing and inspection rules. Importers should give clear papers to prove they comply. You can use this table to see the main tests for API 5L Grade B pipes:
Testing Requirements | Description |
|---|---|
Hydrostatic test | Needed for each pipe |
Non-destructive testing | 100% weld ultrasonic or radiographic testing |
Visual inspection | Inside and outside surfaces of each tube |
Charpy V-Notch impact test | Per batch, set temperature and energy |
Hardness test | If needed, like acid service conditions |
Dimension and tolerance checks | Stricter checks needed |
Weight Check | Needed for compliance |
Look for these details in importer documents:
