Alloy Steel A335 P1 Pipes

A335 Grade P1 Pipe is a low alloy carbon steel (Cr-Mo) that is self quench in air, where the welding adquire high hardnees and residual stress not recomended to put it directly in services that demand critical conditions. Such situation requires apply POSTWELD HEAT TREATMENT (PWHT). If you want to avoid PWHT then you can use preheat(120deg celsius) while welding A335 Grade P1 Pipe. PWHT is required if the thickness of ASTM A335/ASME SA335 P1 Alloy Steel Pipe is greater than 13 mm. Please refer ASME B 31.3 table 331.1.1Port: JNPT PORT, MUMBAI (INDIA)
