Product Description
Production Information : PN-EN 10217-6 Welded steel tubes for pressure purposes; submerged arc welded non-alloy steel tubes with specified low temperature properties
·
Title:: PN-EN 10217-6
Welded steel tubes for pressure purposes – Technical delivery conditions -- Part 6: Submerged arc welded non-alloy steel tubes with specified low temperature properties
Scope of the standard:
The standard specifies the technical delivery conditions for circular submerged arc welded pipes with specified low temperature properties manufactured of non-alloy steels. It specifies the requirements for taking samples and the methods of testing.
Circular welded pipes manufactured of non-alloy steel with specified low temperature properties. / from 406,4 to 2540 mm /
Steel grades: P215NL and P265NL
Two testing categories are also distinguished in this case:
· TC1
· TC2
which differ with respect to the test type and, most of all, with the fact that ultrasound testing is introduced in the case of the TC2 group.
Pipe manufacturing stages and delivery conditions:
· Hot rolled or normalized sheets or strips, cold forming, SAW welding and normalization or without further thermal processing
forming with normalization, SAW welding without further thermal processing
| Mandatory tests | |
| for the TC1 category | for the TC2 category |
| Ladle analysis | |
| Tensile testing of the base material in room temperature | |
| Tensile testing of the weld in room temperature for D>=508 mm | |
| Resilience testing of the base material in low temperature | |
| Bend testing of the weld | |
| Resilience testing of the weld in low temperature | |
| Tightness testing | |
| Dimension verification | |
| NDT of the weld | |
