Utilizing cutting-edge Electric Resistance Welding (ERW) techniques, these tubes boast exceptional dimensional accuracy, a smooth surface finish, and reliable mechanical performance. Rithav adheres to strict European standards, ensuring that their tubes are perfect for cold drawing and further fabrication. Renowned for their consistent quality and durability, Rithav’s ERW tubing solutions are a go-to choice for high-performance systems that demand tight tolerances and outstanding structural integrity.
EN 10305-2 / EN 10305-3 ERW Tubing is generally made from non-alloyed low carbon steels like E235, E275, and E355. The composition features carbon (≤0.22%), manganese (≤1.6%), along with small amounts of phosphorus and sulfur. These tubes are known for their impressive mechanical strength, with tensile strength ranging from 340–600 MPa, yield strength from 235–420 MPa, and elongation of at least 22%. They provide excellent formability, weldability, and dimensional accuracy, particularly after cold drawing. The ERW process guarantees clean weld seams and uniform properties, making the tubing perfect for demanding fabrication and structural uses.
