Boilers And Pressure Vessels
Jis g3455 carbon steel pipes, designed for high-pressure service up to 350°c, offer excellent strength and durability. available in grades sts 370, sts 410, and sts 480, ideal for boilers, pressure vessels, and industrial piping.
JIS G3455 Carbon Steel Pipes are engineered for high-pressure service at temperatures up to 350°C, making them ideal for boiler pipeline protection and industrial piping. Conforming to the Japanese Industrial Standard (JIS), these seamless pipes are designed to withstand demanding conditions in applications such as boilers, pressure vessels, and high-pressure equipment in industries like power generation, oil and gas, and chemical processing. Available in grades STS 370, STS 410, and STS 480, these pipes offer excellent strength, ductility, and corrosion resistance.
Manufactured using killed steel through seamless processes (hot-finished or cold-finished), JIS G3455 Carbon Steel Pipes are available in outer diameters from 10.5 mm to 660.4 mm and wall thicknesses from 2 mm to 60 mm. Lengths can be fixed (6m, 9m, 12m, 24m) or customized (5-12m) to meet project requirements. The seamless construction ensures uniform wall thickness and structural integrity, critical for high-pressure applications. Heat treatments such as normalizing or tempering enhance mechanical properties, ensuring reliable performance under pressure and thermal stress.
The chemical composition of these pipes, with controlled carbon, silicon, manganese, phosphorus, and sulfur content, provides good weldability and moderate corrosion resistance, suitable for handling steam, water, oil, and gas in harsh environments. For instance, STS 480, with higher carbon content (up to 0.33%), offers superior tensile strength (481 MPa minimum) compared to STS 370 (370 MPa minimum). Rigorous testing, including tensile, flattening, bending, hydrostatic, and nondestructive examinations, ensures compliance with JIS G3455 standards. Surface treatments like galvanizing or varnishing enhance durability, while plain or beveled ends facilitate easy installation.
JIS G3455 Carbon Steel Pipes are widely used in high-pressure steam boilers, pipelines, and industrial systems requiring robust performance under temperatures up to 350°C. Their seamless design and high-pressure resistance make them suitable for pressure vessel pipes and compressed air systems in manufacturing. Compared to JIS G3454 (for lower pressure) or JIS G3456 (for higher temperatures), JIS G3455 offers a balanced solution for high-pressure, moderate-temperature applications, with excellent dimensional accuracy and cost-effectiveness.
These pipes address challenges like pipeline wear, pressure surges, and thermal cycling in industrial systems. Their robust construction and quality assurance make them a reliable choice for engineers seeking durable industrial piping solutions for high-pressure environments, ensuring safety, longevity, and minimal maintenance.
