Carbon Steel JIS G3462 pipes are either seamless or welded steel pipes crafted in line with the Japanese Industrial Standard (JIS) G3462. This standard lays out the essential requirements for carbon steel pipes, which are mainly used in pressure vessels, boilers, and heat exchangers. Companies like Bosega Pipes & Tubes in Cape Town, South Africa, supply these pipes, which are engineered to deliver exceptional strength, durability, and reliability, especially in high-pressure and high-temperature settings. Their consistent quality and strict adherence to JIS standards make them ideal for critical industrial applications where safety and performance are paramount.
Typically, the composition of JIS G3462 carbon steel pipes includes a carbon content of up to 0.25%, along with manganese (0.3–0.8%), and controlled amounts of silicon, sulfur, and phosphorus. These pipes usually boast tensile strengths ranging from 410 to 540 MPa and yield strengths between 240 to 370 MPa, depending on the specific grade and heat treatment. They are known for their good toughness, weldability, and resistance to deformation under pressure, making them a dependable choice for challenging mechanical and thermal environments.
