welded pipe fiiting

[tprimaterial]

Hello! Do you use P91 welded pipe fittings, such as weld Tees?

I personally have not needed to specify WP91 fittings at any of our Power Plants. This material is permitted, however, for use as fittings in accordance with ASME B16.9, SA-234 Grade WP91.

Be aware of specific welding requirements for using WP91 material - proper selection of filler metal, preheat and post weld heat treatment requirements.

Thank you for your reply! so WP91 include seamless and weld Tee, and the thickness should be different for the same conditions?
