ASTM A213 TP347 Stainless Steel Tubes For High-Temperature And High-Pressure Superheaters and Reheaters
1. Description
A213 TP347 is a very mature steel in stainless steel seamless steel pipe.
Recently, the thermal power industry has been developed in various countries. A213 TP347 stainless steel seamless steel pipe will be used in the boiler of power station, and the demand for this brand of stainless steel seamless steel pipe is growing. A213 TP347 belongs to Cr Ni austenitic stainless steel containing niobium. Because of its stable element Nb, it has good intergranular corrosion resistance, high endurance strength and oxidation resistance. In addition, it has good bending and welding properties.
Allowable use temperature: This grade stainless steel seamless steel pipe can be used in high temperature and high pressure environment. For pressure parts, the maximum working temperature can reach 650 ℃, and for anti-oxidation parts, the maximum anti-oxidation service temperature can reach 850 ℃.
Applicable industry: A213 TP347 stainless steel seamless steel pipe is mainly used to make high temperature reheater, high temperature superheater, high temperature section of platen superheater and various pipe fittings with high temperature and high pressure resistance on large power generation boiler with subcritical and supercritical pressure parameters.
