JIS G3456 Carbon Steel Seamless & ERW Pipe for High Temperature Service

JIS G3456 Carbon Steel Seamless & ERW Pipe

JIS G3456 Carbon Steel Pipes are specially designed for situations where high working pressures and temperatures above 350℃ are required. They are used in a wide range of fields such as boilers, power, machinery, gas tanks, chemical engineering, offshore and petroleum engineering.

We offer both Electric Resistance Welded (ERW) und Nahtlose Rohre, produced by hot-working or cold-working manufacturing processes. ERW pipes and seamless pipes have the same outer diameter range from 15.0 to 660mm. The wall thickness of ERW pipes is 2 to 20mm and the wall thickness of seamless pipes is 2 to 50mm.

The steel grades we offer are STPT370, STPT410 und STPT480. The pipes are available with plain or beveled ends and we can provide custom lengths as required.

We ensure that our pipes meet the strict standards of JIS G3456, providing reliable and long-lasting solutions for your pipe needs.
