T91/P91 boiler tube is a 9Cr-1Mo-V-Nb ferritic alloy steel tube used for high-temperature boiler, superheater, reheater and power plant piping systems. T91 is commonly supplied under ASTM A213 for seamless boiler tubes, while P91 is commonly supplied under ASTM A335 for high-temperature service pipes. The grade provides high creep strength, oxidation resistance and reliable performance in elevated temperature service.
Materials can be cut to required sizes according to customer specifications or project needs.
Different surface finishes can be supplied according to product type and application requirements.
Processing services such as cutting, machining, heat treatment or surface finishing can be arranged upon request.
Products are packed for international transportation with flexible delivery support for global buyers.
For use in high-temperature, high-pressure boilers, steam piping, and power plant equipment.
Suitable for applications such as power plant boiler superheaters and reheaters, high-temperature steam piping, pressure piping, thermal power plant piping systems, and petrochemical high-temperature pipe fittings. It is designed for high-temperature, high-pressure, and creep-resistant service conditions.|
