En 10219 square And Rectangular Hollow Section is made up of strong carbon steel, corrosion resistant, and ductile. The pipes can come in different types, shapes, and dimensions. The material is made up of carbon, silicon, manganese, phosphorus, sulfur, and niobium in the content. The EN 10219 Pipe Standard mandates the pipe wall thicknesses to range from 1.8mm to 14.27mm. The minimum yield strength of the pipes is 345MPa and the minimum tensile strength is 510MPa. The material could be welded without the risk of welding crack or localized corrosion risk at the welded points. The applications include oil and gas, petroleum, petrochemical, and in power plant applications. EN 10219-1 steel pipe specified for Cold formed welded structural hollow sections of non-alloy and fine grain steels.

a. The deoxidation method is designated as follows:FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al).b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document. |
