适用范围： This Part of EN 10253 specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of carbon and alloy steel which are intended for pressure purposes at room temperature, at Iow temperature or at elevated temperatures, and for the transmission and distribution of fluids and gases. It specifies: -- type of fittings; -- type A: Butt-welding fittings with reduced pressure factor; -- type B: Butt-welding fittings for use at full service pressure;-- steel grades;-- mechanical properties;-- dimensions and tolerances;-- requirements for inspection and testing;-- inspection documents;-- marking;-- protection and packaging.NOTE In the case of a harmonised supporting standard for materials, presumption of conformity to the ESRs is limitedto technical data of materials in the standard and does not presume adequacy of the material to a specific item ofequipment. Consequently it is essential that the technical data stated in the material standard be assessed against thedesign requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.
