ASTM A249 TP347 Welded Stainless Steel Tubing introduction
ASTM A249 TP347 welded stainless steel pipe is designed for high temperature above 650℃, intergranular corrosion sensitive and high pressure working conditions. Its corrosion resistance, creep strength and long life are significantly better than 304 stainless steel without stabilization treatment, which prolongs the service life of the pipe in complex corrosive environment and becomes the core material of supercritical boiler and high temperature steam pipe.
ASTM A249 TP347 stainless steel thin wall pipe is matched with Nb-containing ER347 welding wire and E347 welding rod when welding, and supports TIG/MIG/ welding rod arc welding.

ASTM A249 TP347 Welded Stainless Steel Tubing Application
Power industry:
Power station boiler superheater and reheater tubes (withstand 650-750℃ high temperature steam), resist oxide scale peeling and intergranular corrosion;
Supercritical/ultra-supercritical unit pipelines, meet stringent high temperature and long-lasting strength requirements.
Petrochemical:
Catalytic cracking unit and high temperature cracking furnace pipelines, withstand hydrocarbon media and high temperature sulfur corrosion;
Reactor and heat exchanger pipes, cope with halogen (such as Cl⁻) or strong oxidizing environments.
