EN 10217 Welded steel line pipes HFI/HFW or SAW for pressure purposes are produced from plates or strip as welded or fusion welded tubes with longitudinal or spiral seam. This material is often used as line pipes for media flow, particularly hot steam in energy plants and pipe systems for the chemical and petrochemical industry. Certain parts of EN 10217 are diverse and, depending on the welding method as well as the steel group, we can distinguish 7 parts of the norm, whereas the last 7 th part concerns stainless tubes.
Below you shall find our full offer for welded line pipes.
