Specifies requirements for the design and construction of steel pipelines and associated piping components that are used to transmit single phase and multiphase hydrocarbon fluids. Applies where the temperature of a fluid is within the range of -30 degrees Celsius to 200 degrees Celsius, and either the maximum allowable operating pressure is more than 1050 kPa or the hoop stress exceeds 20 percent of the specified minimum yield.

This Standard specifies requirements for the design and construction of steel pipelines and associated piping and components that are used to transmit single phase and multiphase hydrocarbon fluids, such as natural and manufactured gas, liquefied petroleum gas, natural gasoline, crude oil, natural gas liquids and liquid petroleum products. The Standard applies where-(a) the temperatures of the fluid are not more than 200C nor less than -30C; and (b) either the maximum allowable operating pressure (MAOP) of the pipeline is more than 1050 kPa, or at one or more positions in the pipeline the hoop stress exceeds 20% of the SMYS.Except for the exclusions listed in Clause 1.2, this Standard applies to flowlines and gathering pipelines on land and between submarine production facilities. The Standard also applies to pipelines between terminals (see Figures 1.1(A) and 1.1(B)). The extent of the pipelines extends only to where the pipeline is connected to facilities designed according to other Standards. In general, flowlines commence at the wellhead assembly outlet valve on a wellhead, terminate at the inlet valve of the collection manifold, and include piping within facilities integral with the pipeline, such as compressor stations, pump stations, valve stations and metering stations.
