EN 10217-7 is the European standard governing the technical requirements for welded stainless-steel tubes used under pressure. It specifies criteria such as chemical composition, mechanical properties, weld seam quality, dimensional tolerances, and testing methods. Compliance with this standard ensures that tubes can safely operate in demanding conditions, including high temperatures, corrosive environments, or hygienic applications.
Manufacturers must follow strict production procedures, including continuous weld monitoring, heat-treatment verification, and destructive as well as non-destructive testing. These may include eddy-current inspections, tensile testing, flattening tests, and intergranular corrosion assessments. Documentation and traceability play a critical role, as every batch must be fully traceable from raw material to final inspection. For companies supplying to the food industry, chemical processing, or pressure-equipment markets, adherence to EN 10217-7 is not merely a formality but a competitive advantage—ensuring quality, safety, and alignment with EU regulatory expectations.
