Weldable Carbon Steel Pipes For Construction And Machinery
Jis g3101 ss400 steel pipes for structural applications, offering excellent weldability and moderate strength. ideal for construction, machinery, and general piping with corrosion resistance.
JIS G3101 SS400 Steel Pipes are designed for general structural purposes, offering excellent weldability, moderate strength, and corrosion resistance. Conforming to the Japanese Industrial Standard (JIS G3101), these carbon steel pipes are widely used in construction piping, machinery, and general piping solutions across industries such as building construction, infrastructure, and manufacturing. The SS400 grade is known for its versatility and cost-effectiveness in structural applications.
Available in both seamless and welded forms (e.g., ERW or SAW), SS400 Steel Pipes are manufactured with outer diameters ranging from 21.3 mm to 610 mm and wall thicknesses from 2 mm to 60 mm. Lengths can be standard (6m, 12m) or customized (5-12m) to suit project requirements. The pipes are typically hot-rolled or cold-formed, with optional heat treatments like normalizing to improve mechanical properties. Their low carbon content ensures superior weldability, making them suitable for fabrication processes like bending, flanging, and welding.
The chemical composition of SS400, with carbon (≤0.30%), phosphorus (≤0.050%), and sulfur (≤0.050%), provides good formability and moderate corrosion resistance. These pipes undergo testing, including tensile, bending, and hydrostatic tests, to ensure compliance with JIS G3101 standards. Surface treatments such as black painting, galvanizing, or anti-corrosion coatings enhance durability, while plain, beveled, or threaded ends facilitate installation. SS400 pipes are ideal for low to medium-pressure applications, offering reliable performance in structural frameworks.
JIS G3101 SS400 Steel Pipes are commonly used in building frameworks, bridges, machinery components, and general piping systems. Compared to JIS G3454 (pressure piping) or JIS G3445 (machine structural tubes), SS400 pipes are optimized for structural integrity and weldability rather than high-pressure or precision applications. Their ability to resist pipeline wear and environmental corrosion makes them a preferred choice for cost-effective structural solutions.
These pipes address challenges like structural stability, corrosion, and fabrication complexity in construction and industrial systems. Their robust design, compliance with JIS G3101, and versatility make them a dependable choice for engineers seeking durable structural carbon steel pipes for diverse applications, ensuring safety, efficiency, and longevity.
