ASME SA213 TP347H Stainless Steel Tubes For High-Temperature And High-Pressure Superheaters and Reheaters
1. Description
SA213 TP347H stainless steel seamless steel pipe
In recent years, with the rapid development of thermal power industry in various countries, the demand of SA213 TP347H (1cr19ni11nb) stainless steel seamless steel tube for power plant boiler industry is increasing day by day. SA213 TP347H belongs to Cr Ni austenitic stainless steel containing niobium. Because of its stable element Nb, sa-213tp347h has not only good intergranular corrosion resistance, high endurance strength and oxidation resistance, but also good technological properties such as bending and welding.
Allowable use temperature: the steel pipe made of this material can be used in high temperature and high pressure environment. For pressure parts, the maximum working temperature can reach 650 ℃; for anti-oxidation parts, the maximum anti-oxidation use temperature can reach 850 ℃.
Applicable conditions: SA213 TP347H stainless steel seamless steel pipe is mainly used for making high temperature superheater, high temperature reheater, high temperature section of platen superheater and various high temperature and high pressure resistant pipe fittings and other components on large power generation boiler with subcritical and supercritical pressure parameters.
