ASTM A358 TP347 Stainless Steel EFW Pipes
Advantages of SS 347 class 3 EFW Piping
A358 TP347 stainless steel EFW pipe strictly follows international and domestic standards such as ASME SA-213/SA-213M, ASME SA-312/SA-312M, GB/T13296, GB/T14976, etc. After solution treatment at 1000-1100℃, the intergranular corrosion tendency of the pipe is eliminated and the corrosion resistance is significantly improved.
As an austenitic stainless steel, A358 TP347 EFW pipe has good weldability, but due to poor thermal conductivity and large linear expansion coefficient, it is necessary to focus on preventing risks such as thermal cracks, reheating cracks, intergranular corrosion and stress corrosion during welding.
