Pipeline and fluid seamless pipe is a steel pipe for fluid delivery. Widely used in the delivery of fluid pipe transport of oil, natural gas, gas, water and some solid materials such as pipeline.Pipeline and fluid seamless pipe main steel grade:API 5L gradeA,grade B,X42,X52,X60,X65 and so on.
API 5L steel pipes are steel pipelines widely used in petroleum and natural gas industries, like conveying gas, water, and oil. The American Petroleum Institute specification API 5L covers seamless steel line pipe and welded (SAW, ERW, CDW )steel line pipe. API Line pipe is best & economical piping solution for transportation of gas, water, and oil. There are grades Grade A, B, X42, X52, X56, X60, X65, X70, X90 and X100. The two digit number following the "X" indicates the Minimum Yield Strength (in 000’s psi) of pipe produced to this grade. The technical committee made recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2. PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.
API 5L PSL 2 is more stringent requirement as compare to API 5L PSL1 , in API 5L PSL2 charpy test is mandatory, tensile strength and chemical composition is more as compare to API 5L PSL1. Due to the different pipe forming types, API 5L PSL 2 steel pipes has different delivery condition with the relative suffix like “R”, “N”, “Q”, “M”. For the different delivery conditions, API 5L PSL 2 steel pipes have different chemical composition, mechanical properties requirements.
API 5L steel pipe is available in seamless pipe and welded pipe, mainly used for pipeline transportation systems in the petroleum and natural gas industries.
