Seamless And Welded Carbon Steel Pipeline Tubes, Designed To En 10208-1/-2 Standards For Safe Combustible Fluid Transport.
En 10208 carbon steel pipes meet european standards for transporting gas, oil, and combustible fluids, offering precise tolerances, certified materials, and robust quality for mining, chemical, and power industries.
EN 10208 carbon steel pipes are engineered for pipelines transporting combustible fluids, such as gas, oil, and other flammable substances, in industries like mining, chemical, and power engineering. These pipes comply with the European standard BS EN 10208, which specifies technical delivery conditions for seamless and welded steel pipes used primarily in gas supply systems, excluding petroleum and natural gas industry pipelines covered by ISO 3183.
Available in both seamless and welded forms, EN 10208 pipes are manufactured with outer diameters ranging from 10.2 mm to 660 mm. Seamless pipes have wall thicknesses up to 40 mm (hot-rolled) or 10 mm (cold-drawn), while welded pipes, including LSAW (Longitudinal Submerged Arc Welded) and SSAW (Spiral Submerged Arc Welded), support larger diameters. These pipes are designed to withstand specific pressures, making them ideal for gas pipeline steel and oil transport pipes in demanding environments.
The standard is divided into two requirement classes: Class A (EN 10208-1) for standard quality and Class B (EN 10208-2) for enhanced toughness and non-destructive testing, suitable for transmission pipelines. Common steel grades include L210GA, L235GA, L290GA, and L360GA, with yield strengths from 210 MPa to 360 MPa. The pipes undergo rigorous testing, such as hydrostatic, Charpy impact, and weld seam inspections, to ensure reliability and prevent issues like shear fracture in gas pipelines.
EN 10208 carbon steel pipes offer excellent mechanical properties, with options for coatings like polyethylene or epoxy for enhanced corrosion resistance. They are versatile for applications in gas supply systems, chemical processing, and power plants, providing cost-effective and durable solutions for fluid transport under pressure. Compared to standards like ASTM A53 or DIN 2458, EN 10208 emphasizes specific requirements for combustible fluid pipelines, ensuring safety and performance.
These pipes address challenges like high-pressure fluid transport and environmental durability, making them a preferred choice for engineers and project managers in infrastructure projects requiring welded carbon steel pipes for combustible fluids. Their compliance with stringent standards ensures long-term performance in critical applications.
EN 10208 pipes are seamless and welded carbon steel tubes designed per European standards (Parts 1–3) for combustible fluid transport in mining, chemical processing, power, and gas distribution systems.
Designed to withstand specific pressures for combustible fluid transport.
Welded options provide affordable solutions for large-scale pipelines.
Suitable for gas, oil, and chemical fluid transport systems.
