EN 10219 is a technical specification for cold-formed welded hollow structural profiles in the European Union, applicable to steel pipes used in load-bearing structures such as buildings and civil engineering. This standard specifies the requirements for product size, chemical composition, mechanical properties (such as tensile strength, yield strength, impact strength), weldability, etc., and specifies that weld forms include spiral and straight lines. At the same time, the standard requires enterprises to pass initial type inspection (ITT) and factory production control system (FPC) certification to ensure that their products comply with regulatory requirements.

Spiral steel pipes that comply with EN 10219 are usually made of steel such as S235JRH and S355J2H, and are formed into circular or rectangular sections through cold forming and welding processes. The product must meet strict requirements for carbon equivalent, elongation, and surface condition. Some high-end products may also undergo 3PE anti-corrosion coating treatment to improve corrosion resistance. For example, spiral steel pipes made of S355JRH material are widely used in oil and gas transportation and building structures. Their production process involves high-frequency welding, submerged arc welding and other technologies, and requires non-destructive testing of weld quality.
