What is the JIS G3455 Grade STS 480 Pipe?

JIS G3455 Grade STS 480 under the Japanese Industrial Standards (JIS) describes a high-strength variety of carbon steel seamless pipe. Its particular design is meant to safely and consistently manage high heat and pressures. Crucially for leak-proof performance and structural stability under high stress, the perfect production method removes welds to guarantee a homogeneous structure with constant wall thickness and exceptional mechanical integrity. With a clear rise in strength above lower classes such as STS 410, the "480" in STS 480 denotes a minimum tensile strength of 480 MPa. For important systems including high-pressure gas distribution, difficult power plant circuits, steam pipes, and refinery operations where operational integrity is crucial, high strength, toughness, and superior weldability combined optimally make JIS G 3455 Grade STS indispensable.
