ASTM A312 Gr Tp304H Solid Finned Pipe

1. ASTM A312 TP304H Solid Finned Pipe Definition:

ASTM A312 TP304H solid finned pipe refers to a specific type of pipe that is made from ASTM A312 Grade TP304H stainless steel material and features solid fins attached to its outer surface. The fin material grade "18-8-Cr-Ni" refers to a stainless steel alloy that contains approximately 18% chromium (Cr) and 8% nickel (Ni). This alloy is commonly known as "18-8 stainless steel" or "Type 304 stainless steel." The solid fins are tightly wound and welded onto the pipe, increasing the surface area for improved heat transfer.
