A269 TP347/347H High Pressure Stainless Steel Pipe
GNEE manufactures and supplies A369 TP347H stainless steel pipe. With many years of experience, GNEE produces A369 TP347H seamless pipes, which are suitable for many industries.
A369 TP347 is a niobium stabilized austenitic stainless steel tube with good general corrosion resistance and excellent intergranular corrosion resistance after exposure to chromium carbide precipitation temperature range 427 – 816°C. A369 TP347H stainless steel pipe is a high carbon version of A369 TP347. A369 TP347H high temperature pipe is designed to increase creep resistance and achieve greater strength at temperatures above 537°C.
A369 TP347/H pipe has good high temperature strength and general corrosion resistance as well as excellent processing characteristics. The chromium and nickel components give good oxidation resistance and carburization properties. Can be used in chemical, petrochemical, oil and gas refineries, pharmaceuticals, and paper industries.
