API 5L pipes are associated with their use in the petroleum industry. In addition to being used in petroleum industries, the API 5L Seamless Pipe is a part of the natural gas and water industries as well. As expected, these pipes ferry across media from the point of origin which could be refineries or factories to different endpoints. The media transported via the API 5L X80 Pipe may include liquids like water or petroleum and gases like natural gas or steam. Chemically, these pipes are classified as carbon steel alloys and they are produced n various pipe schedules ranging from SCH 10 to SCH 160 as well as SCH XXS. The nominal API 5L X52 Pipe Sizes ranges from ½ inch to the last size range ending at 42 inches.
The American petroleum institute API 5L Erw Pipe Specification takes into consideration pipes produced from both seamless and welded construction. The institute created two specification levels for the products, which are referred to as PSL (product specification levels) in short. These levels delineate themselves from each other on the basis of the chemical composition of the API 5L X70 Seamless Pipes, as well as the test methods that are suggested by these levels. Like most specifications, the API 5L pipe is segregated into various grades, which is marked by an X followed by a numeric value. The numeric value, as is the case in the API 5L X42 Carbon Steel Pipe denotes the Minimum Yield Strength of the pipe produced in 000’s psi. Therefore the minimum yield strength of an API 5L X60 Pipe would be 60000 psi.
