PI 5L Seamless Pipes are a type of steel pipes that adhere to the specifications outlined by the American Petroleum Institute (API). These pipes are designed for use in conveying gas, water, and oil in both the oil and natural gas industries. The "5L" in API 5L stands for "Line Pipe," indicating its primary application for transporting fluids and gases from one point to another.
API 5L Specification Covers Seamless and Welded Steel Line Pipe. It includes standard-weight and Extra-Strong threaded Line Pipe. It includes standard-weight and extra-strong threaded line pipe; and standard-weight plain-end, regular-weight plain-end, special plain-end, extra-strong plain-end, special plain-end, extra-strong plain-end pipe; as as well as bell and spigot and through-the-flow line(TFL) pipe. The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, Groundwater, and oil in both the oil and natural gas industries Grades covered by this specification are A25 ,A ,B (and the following "X" Grades) X42, X46, X52, X60, X65, & X70 and API 5L Line Pipe is dimensionally equivalent to A106 and A53 pipe, conforming to industry standard sizes, however it performs to different mechanical properties. One key defining characteristic of this pipe is its yield strength, where the two digit number following the pipe’s "X" grade indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade (i.e. X52 Pipe).
The purpose of this specification is to provide standards for pipes suitable for the transportation of gas, water and oil, both in the oil and natural gas industries. This specification applies to seamless and welded steel line pipe. This includes plain-end, threaded-end, and bell-end tubing, as well as through-the-future-line (TFL) tubing and tubing with engineered ends for use in specialty couplings. Plain-ended line pipes meeting this specification are primarily intended for field assembly by circumferential welding, but the manufacturer is not responsible for field welding.
This specification specifies requirements for two products Specification level (PSL I and PSL 2). These two PSL specifications define different levels of standard technical requirements. PSL 2 sets mandatory requirements for carbon equivalent, notch toughness, ultimate yield strength, and ultimate tensile strength. These and other differences are: They are summarized in Appendix 1. Requirements that apply only to PSL I or only to PSL 2 are marked as such. Requirements not tied to a specific PSL apply to both PSL I and PSL 2.
API 5L Seamless Pipes are available in a variety of sizes and grades to suit different application requirements. They come in diameters ranging from a few inches to several feet, with various wall thicknesses and lengths available. Additionally, different steel grades, such as API 5L Grade B, X42, X52, X60, and X65, offer specific properties tailored to specific operating conditions.
The size used here is a dimensionless designation derived from the specified outside diameter measured in U.S. units, and provides a convenient way to refer to pipe sizes in text and tables (but (Not used for ordering instructions). Pipe sizes larger than 23/8 are expressed as whole numbers and fractions. Pipe sizes smaller than 23/8 are displayed to three decimal places. These sizes replace the terms ``size designation'' and ``nominal size designation'' used in previous editions of this specification. Users of this specification who are accustomed to specifying nominal sizes instead of 00 sizes are encouraged to familiarize themselves with the new sizing specifications used in this specification. and API 5L Seamless Pipes comply with strict Piping Specification set forth by the American Petroleum Institute, ensuring consistency and compatibility with other components in Oil Sands and gas Pipeline. These specifications cover dimensions, chemical composition, mechanical properties, and testing requirements to guarantee the quality and performance of the pipes.
Steel coils or plates are formed into cylindrical shapes and longitudinal seams are welded using advanced welding techniques. After the tube forming stage, the API 5L tube undergoes a heat treatment process to improve its mechanical properties and microstructure.
The seamless process is a process of hot working steel to form a tubular product without a welded seam. If necessary, the hot worked tubular product may be subsequently cold finished to produce the desired shape, dimensions, and properties.
Continuous welding is a process in which the steel is continuously flowed into the welding machine by heating the bar in a furnace and forming a seam by mechanically pressing the formed edges, joining successive coils of the bar. (It is a type of butt welding.)
Laser welding is a welding process that uses a laser beam and keyhole technology to melt and fuse the edges to be welded. You can preheat the edges. Shielding is carried out entirely by externally supplied gases or gas mixtures.
Gas metal arc welding is a welding process that fuses metals by heating them with one or more arcs between a continuously consuming electrode and a workpiece. Shielding is carried out entirely by externally supplied gases or gas mixtures. No pressure is applied and the filler metal is recovered from the electrode.

The suffice (R, N, Q or M) for PSL2 grades, belongs to the steel grade |
Pipe to withstand a hydrostatic test without leakage through the weld seam or the pipe body. Jointers need not be hydrostatic tested provide the pipe sections used were successfully tested.
No cracks shall occur in any portion of the test piece and no opening of the weld shall occur.
Acceptance criteria for flattening test shall be:
Many PSL2 pipe sizes and grades require CVN. Seamless Pipe is to be tested in the body. Welded pipe is to be tested in the body, pipe weld and heat-affected zone. Refer to the full API 5L specification for the chart of sizes and grades and required absorbed energy values.
