Line pipe standard Line pipe execution standard

Line pipe standard Line pipe execution standard is API 5L The pipeline steel pipe standard ,however,China issued two line pipe national standards in 1997.Usually, the main transmission pipeline specifications is for ..1-1997The oil and gas industry conveying pipe and delivery technology conditions the first part: level A steel tube and GB/T9711.The pipelines,transporting oil,gas, mainly divided into the main transmission pipeline, regional transportation pipeline and the urban pipeline 3 kinds. Line pipe classification Line pipe is the abbreviation of pipeline carbon steel pipe that used for conveying oil,product oil, natural gas and water in the oil and gas industry.. Line pipe grade and chemical components Line pipe steel grade from low to high is divided into:

The pipelines,transport.they are GB/T9711.Introduction of Line Pipe Technology Articles | January 11, 2017 Line pipe classification Line pipe is the abbreviation of pipeline carbon steel pipe that used for conveying oil,product oil, natural gas and water in the oil and gas industry.114^700mm,wall thickness for 6^20mm,steel grade for X42^X80. In addition,according to the manufacture process and the tube bloom used different shapes,the line pipe can be divided into seamless steel pipe and welded steel pipe,among the usage quantity of welded steel pipe is more than seamless steel pipe.2-1997The oil and gas industry conveying pipe and Stainless Steel Screw Conveyors Suppliers delivery technology conditions the second part: level B steel tube ..the two standards are equivalent to API 5L ,thus, domestic many users requir supply according the two national standards.406^1219mm,wall thickness for 10^25mm,steel grade for X42^X80,the regional transportation pipeline and the urban pipeline usually specifications is for
