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.
