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.【中国标准分类号】: H48【国际标准分类号】: 23_040_40;77_140_20;77_140_45【页数】: 127P.;A4【正文语种】: 英语
