EN 10210 S355J2H is a hot-finished structural hollow section manufactured in accordance with the European standard EN 10210. It features a minimum yield strength of 355 MPa for wall thicknesses up to 16 mm and offers excellent toughness at low temperatures, capable of withstanding impacts down to -20°C. This makes it a versatile choice for a wide range of applications in construction and engineering industries.
May 30, 2025 read moreElectric Resistance Welded (ERW) steel pipes are widely used in construction, oil and gas transportation, water pipelines, and structural applications due to their high efficiency and uniform wall thickness. One critical aspect that buyers and engineers must understand when selecting ERW steel pipes is dimensional tolerance. Precise dimensions directly affect installation accuracy, structural integrity, and cost-efficiency. In this blog post, we’ll explore what dimensional tolerance means for ERW pipes, why it matters, and how international standards define it.
May 29, 2025 read moreWelding is a critical step in the production of Electric Resistance Welded (ERW) carbon steel pipes, directly affecting their strength, integrity, and durability. However, due to the complexity of the welding process and material characteristics, various defects can occur if proper procedures are not followed. This article outlines the most common welding defects found in carbon steel ERW pipes, their causes, characteristics, and potential impacts on performance.
May 22, 2025 read moreCarbon steel Electric Resistance Welded (ERW) pipes are widely used in various industries due to their cost-effectiveness and manufacturing efficiency. Produced through a high-speed continuous process, ERW pipes are known for their versatility in applications ranging from structural components to oil and gas pipelines. However, like any material, they come with both advantages and limitations. Understanding these pros and cons is essential for making informed decisions in project design, material selection, and engineering application.

May 15, 2025 read moreRoll forming is a widely used method in Electric Resistance Welded (ERW) pipe production. It involves using metal sheets or coils as raw materials, which are gradually bent and shaped through a series of roll stands equipped with specially designed forming rollers. Each stand typically includes two or more rollers, and the material undergoes continuous deformation until it achieves a uniform cross-section.
May 14, 2025 read moreWhen selecting steel pipes, a common question is whether to use seamless or welded pipes. Making the right choice is essential to ensure the pipeline's stability, durability, and cost-effectiveness. A key factor in this decision is the nominal size of the pipe.
