JIS G3455 Carbon Steel Seamless Pipe Manufacturer

JIS G3455 is specifically used to specify carbon steel and alloy steel pipes for use at high temperatures and high pressures. This standard mainly deals with seamless steel pipes for boilers, pressure vessels, and piping systems.

Made of high-quality carbon steel, UNIASEN’s JIS G3455 pipes can withstand temperatures up to about 350°C, making them ideal for pressure, high pressure, and high-temperature applications.

These pipes range in outer diameter from 19.05 mm to 114.3 mm, with wall thicknesses from 2.0 mm to 14 mm and a maximum length of 16000 mm. We offer a variety of surface coatings, end types, joint methods, and processing services to meet your specific needs.
