Title: · PN-EN 10217-5

Welded steel tubes for pressure purposes – Technical delivery conditions -- Part 5: submerged arc welded non-alloy and alloy steel tubes with specified elevated temperature properties

Scope of the standard:

The standard specifies the technical delivery conditions for circular submerged arc welded steel tubes with specified elevated temperature properties manufactured of non-alloy and alloy steels. It specifies the requirements for taking samples and the methods of testing.

Welded pipes of the following types:

· SAWH (spiral welding)

· SAWL (longitudinal welding)


The scope of the standard includes :
Circular submerged arc welded steel tubes with specified elevated temperature properties manufactured of non-alloy and alloy steels./ from 406,4 to 2540 mm /

Steel grades: P235GH ,P265GH, 16Mo3

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


normalized formation , SAW welding without further thermal processing

Mandatory tests
for the TC1 category for the TC2 category
Ladle analysis
Tensile testing in room temperature
Tensile testing of the weld in room temperature for D>=508 mm
Bend testing of the weld
Hydrostatic tightness testing
Dimension verification
NDT of the weld NDT of the base material in order to identify delamination
NDT of pipe ends in order to identify delamination
NDT of sheet edges and strips in order to identify delamination
Material identification for 16Mo3
Additional tests
Check analysis
Tensile testing in elevated temperature
Resilience testing of the base material at the temperature of 20° or 0°C
Longitudinal resilience testing for non-alloy steels at the temperature of –10° C
Resilience testing of weld areas at the temperature of 20° or 0°C
Wall thickness measurement at a distance from pipe ends
