Resumen:
This European Standard specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic-ferritic (duplex) stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperature or at elevated temperatures. It specifies: the type of fittings; type A (see 7.2) type B (see 7.3) the steel grades; the mechanical properties; the dimensions and tolerances; the requirements for inspection and testing; the inspection documents; the marking; the handling and packaging. NOTE In the case of a harmonised supporting standard for materials, presumption of conformity to the Essential Requirement(s) (ESRs) is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently the technical data stated in the material standard should be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive (PED) are satisfied. Unless otherwise specified in this European Standard the general technical delivery requirements in DIN EN 10021 apply.
