ASTM A213 TP347 Seamless Tubes:

ASTM A213 TP347 Seamless Tubes are also advantageous for high temperature service because of its good mechanical properties. Stainless Steel 347 ERW Pipe is offers superior creep and stress rupture. SS UNS S34700 ERW Pipe should be considered for applications which require irregular heating between 800 degrees F to 1650 degrees F or for welding under conditions which prevent a post-weld anneal. Stainless Steel UNS S34700 Seamless Pipes are used in numerous applications such as Aircraft Exhaust Stacks, Cabin Heaters, Heavy Wall Welded Equipment, Oil and Gas Refineries, Petroleum Refining Fluid Catalytic Cracking Units, Polythionic Acid Service, Recuperators, etc.

 

Before we deliver these Stainless Steel UNS S34700 Welded Pipe to our valued clients we conduct thorough quality tests. Those are namely PMI tests, mill tests, raw material tests, 100% radiography, micro tests, intergranular corrosion tests, chemical testing, third party inspection. We perform these tests to make sure that the ASTM A213 TP347 Seamless Tube is free from errors and ideal for use in numerous temperature conditions.
