The API SPEC 5L specification gives standards for pipes suitable for the transit of gas, water, and oil in the natural gas and petroleum industries. API SPEC 5L comprises seamless and welded steel pipes. This includes threaded flared end pipes with smooth ends and flow line pipes (TFLs) and pipes prepared for use with special fittings at the ends.
Pipe manufactured with ASTM 106 Grade A or B is not compatible with API 5L. API 5LX grade requirements are more stringent. Laminate shades are not available, and no modifications are allowed. In addition, special attention is paid to acid services and toughness and toughness tests in higher pressure and temperature classes.
Strength level and desulfurization
Manganese sulphides are typical of all manganese alloy steels. Sulphur content should be kept to a minimum as they tend to separate and reduce impact resistance. Specify a maximum of 0.007%.
Line pipe API standard specifications
PSL1 is a standard grade tube pipe that contains additional chemicals and mechanical to PSL2. Property, And test requirements. You can buy whole amount of material from P11 Pipe suppliers in good quality.
The grades covered by this specification are grades A25, A, B, and "X" X42, X46, X52, X56, X60, X65, X70, and X80. The two-digit number following the "X" indicates the minimum yield strength (thousands of psi) for pipes manufactured in this grade.

API5L Seamless Steel Line Pipe-What is an API 5L Line Pipe?
The straight seam high-frequency welded steel casting method used in LSAW steel pipe production by Yang Steel Pipe has excellent and reliable quality, welding area, stable welding parameters, welding speed, high efficiency, and equipment and technology of the whole production line.
(1) The process of forming straight seam high frequency welded steel pipe returns small residual stress.
(2) The deformation hardening effect is a perfect circle with small and accurate geometric dimensions, which helps to ensure the quality of construction and welding.
(3) Straight seam the shape of the high frequency welded steel bead is good, and edge bites, inner and outer welding misalignment defects are less likely to occur.
(4) Straight seam pipe welding is distributed at a certain point on the circumference, performing it according to the welding demand at a preferable position.
API5L seamless line pipe
API 5L X42seamless line pipes are often graded based on the manufacturing method. API 5L Seamless Pipeline There is two main ways to create a pipe: cold drawing and finishing. Cold drawing refers to a method of pipe construction in which a pipe is drawn or molded at room temperature. This method creates better surface finishes, tighter tolerances, lighter walls, or smaller pipe diameters. Hot Finish API 5L X65Seamless Line Pipes are manufactured without cold finishing. That is, seamless pipes are built when the material is very hot. These two methods are commonly used.
