Product Description

JIS3454 / JIS3455 / JIS3456 / JIS3461 

JIS G3454 carbon steel pipes are used for pressure conditions at a limited maximum temperature of 350℃. If you require higher pressure pipes shall consider JIS G 3455 standard. JIS G3454 Steel pipe can be manufactured into seamless steel pipe or electric-resistance welded steel tubes, the purchaser may designate the quality requirements on hot finished or cold finished state.
