Steel Pipes - EN 10217

EN 10217 is the European standard for welded steel tubes for pressure purposes, usually from 10.2mm to 2540mm in outer diameter and from 1.4mm to 25.4mm in wall thickness. Its application areas include pipeline systems that need to withstand pressure in petroleum, chemical, natural gas, electric power and other industries, as well as occasions where there are pressure requirements for steel pipes in construction, machinery manufacturing and other fields.
