Scope

This standard specifies the requirements and methods for the design, selection and verification of steel butt welded pipe fittings for oil and gas pipelines. When designing and calculating pipe fittings, only the effect of design pressure is considered. When other loads (such as thermal expansion thrust, bending moment, etc.) must be considered, separate analysis should be performed and are outside the scope of this standard. This standard applies to steel butt-welded pipe fittings (pipe heads, reducing joints, elbows, bends and tees) in onshore oil and gas pipeline projects under the following conditions; Design pressure p is not greater than 10MPa; Nominal diameter DN is not greater than 1000mm; the design temperature T is higher than -40℃ and not higher than 120℃;
