May I ask if spiral submerged arc welded pipes can be used for steam pipelines with a pressure of 2 Mpa and a temperature of 300 degrees? Are there any standards?

What materials are used? Are there any specific standards? SY/T 5037 seems unusable; it is only applicable to heating steam. Thank you all! As a supplementary note: the steam pipeline has a DN400 diameter and belongs to GC industrial pipelines; it is approximately 4 kilometers long from the power plant to the factory.

Spiral submerged arc welded pipes cannot be used; 15CrMo should be employed instead
