Recommended Practice for the Pressure Testing of Steel Pipelines for the Transportation of Gas@ Petroleum Gas@ Hazardous Liquids@ Highly Volatile Liquids or Carbon Dioxide (Sixth edition)
This RP applies to all parts of a pipeline or pipeline facility including line pipe@ pump station piping@ terminal piping@ compressor station piping@ metering station piping@ delivery station piping@ regulator station piping@ appurtenances connected to line pipe@ appurtenances connected to facility piping@ fabricated assemblies@ valves@ tees@ elbows@ reducers@ flanges@ and any other pipeline equipment or appurtenances. This RP does not apply to pumping units@ compressor units@ breakout tanks@ pressure vessels@ control piping@ sample piping@ instrument piping/tubing@ or any component or piping system for which other codes specify pressure testing requirements (i.e. ASME Boiler and Pressure Vessel Code@ piping systems covered by building codes@ etc.). Although this RP contains guidelines that are based on sound engineering judgment@ it is important to note that certain governmental requirements may differ from the guidelines presented in this document. This RP does not address piping systems that are pressure tested with natural gas@ nitrogen@ or air.
