Abstract (en)
[origin: WO0202255A1] The invention relates to a method for producing stainless steel press fittings (2) in practically one single working operation, comprising two steps, which can be carried out simultaneously or consecutively. The blank (3) is cut into lengths and is widened and upset in a work tool (5) in order to form the desired pipe connection areas. The method is characterised by its reliability in producing stainless steel press fittings (2). Other pressure-resistant and tough metals can be used. The method is especially suitable for combination with a subsequent rolling step or abrasion step in the production of press fittings (2) made of welded stainless steel.
