适用范围：1.1 This part of EN 10253 specifies the technical delivery requirements for seamless and welded buttweldingfittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austeniticand austenitic–ferritic (duplex) stainless steel without specific inspection requirements.It specifies: steel grades; mechanical properties; dimensions and tolerances; requirements for inspection and testing; inspection documents; marking; handling and packaging.1.2 Limitation of useThe allowed pressures and temperatures are the responsibility of the customer according to the state of theart and in application of the safety coefficients in the application regulations, codes and standards.In common, joint coefficient is used in the calculation of the thicknesses of components which include one orseveral butt welds, other than circumferential: for equipment subject to random non-destructive testing: 0,85; for equipment not subject to non-destructive testing other than visual inspection: 0,7.1.3 Unless otherwise specified in this part of EN 10253 the general technical delivery requirements inEN 100021 apply.
