EN 10219 LSAW and DSAW steel pipes are essential in various structural and engineering applications due to their high strength, durability, and precise manufacturing processes. These pipes provide reliable performance in demanding environments, making them an excellent choice for construction, infrastructure, and mechanical applications.
The EN 10219 standard specifies the technical delivery conditions for cold-formed welded structural hollow sections of non-alloy and fine grain steels. Below are the specifications for various grades, including S235J0H, S275J0H, S275JRH, S275J2H, S355J0H, S355JRH, and S355J2H.
ERW BLACK Pipes. Electric Resistance Welded (ERW) Pipes are manufactured from Hot Rolled Coils / Slits. All the incoming coils are verified based on the test certificate received from steel mill for their chemistry and mechanical properties. ERW pipe is cold-formed into a cylindrical shape, not hot-formed.
Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length. In Seamless pipe, there are no welding or joints and is manufactured from solid round billets.
Longitudinally Submerged Arc Welding Pipe is subdivided into UOE, RBE, JCOE steel pipe according to its different forming methods. Longitudinal high-frequency welded steel pipe has the characteristics of relatively simple process and fast continuous production, and has wide use in civil construction,petrochemical, light industry and other sectors. Mostly used to transport low pressure fluids or made into various engineering components and light industrial products.
The EN 10219 standard specifies the technical delivery conditions for cold-formed welded structural hollow sections of non-alloy and fine grain steels. Below are the specifications for various grades, including S235J0H, S275J0H, S275JRH, S275J2H, S355J0H, S355JRH, and S355J2H.
LSAW steel pipes, whether produced through UOE, JCOE (Press Bending), or JCOE (Roll Bending) methods, are integral to various industrial applications due to their high strength, dimensional accuracy, and compliance with numerous international standards. Each manufacturing process has its unique advantages, making these pipes suitable for transporting fluids and gases, as well as for use in structural and engineering projects.
DSAW pipes are an excellent choice for demanding applications due to their manufacturing precision, strength, and versatility. Whether straight or spiral welded, these pipes meet stringent industry standards and are a reliable solution for transporting fluids and gases under high pressure.
