HP Steam piping

HP Steam piping

HP Steam piping

(OP)
I have HP steam piping with pressure 120 bar and temperature around 375 deg C. What kind of piping material would bev suitable??
Please share your experience. Any specific comment if I will use SA 53 Gr B??

RE: HP Steam piping

Where are you planning to install this line? What are pipe sizes we are talking about? Does the facility has an owner? Does the owner has piping material specs?
I think, A106 Gr.6 seems more approptiate from for the service conditions.

RE: HP Steam piping

In my experience, I have seen ASTM A335 P11 and ASTM A106 Gr. B. But I have not seen ASTM A53 Gr. B for high pressure steam.
Try to put this query in material forums.

RE: HP Steam piping

06B and A106C are most commonly used for this service. In the last 20 years in which I have been involved with over 75 Power Projects, I have never seen A-53 B specified for this service.

RE: HP Steam piping

At 375C(707F) you are near the transition point defined by ASMEB31.1/B31.3 where chrome-moly material is required.

SA106 B/C material is a seamless piping material recommended for this lower temperature steam service. It has been specified specifically for steam service for many, many decades.

A53B is also a carbon steel piping material that may or may not be seamless

At 120 bar, you have a significant pressure system. This design pressure will control your pipe wall thickness.

Suggest that you purchase and review the "Piping Handbook" by Nayaar. It has a chapter on steam piping systems.
