Specification of API 5L Pipe
API 5L Pipe specification is prepared Standard Scope:
The extent of the API 5L line principally incorporates the utilization of the line for water and oil and gas pipeline transmission. Fabricating types: The determination incorporates the assembling types as welded and consistent. Project pipes are not canvassed in the determination.
Pipes under 24″ are generally consistent or ERW, though enormous breadth pipes are SAW/DSAW. LSAW has utilized something like 48″ in size though SSAW/HSAW can be utilized something like 100″ in size.
Various Grades:
API 5L line pipe particular covers Gr. A, B, X42, X46, X52, X56, X60, X65, X70, X80, and so forth. There are different conveyance conditions as expected for various applications.
Material determinations (Chemical and Mechanical): The material datasheet indicates the synthetic creation and mechanical properties of each grade of API 5L line material.
Test Methods: Hydrostatic test is the most widely recognized testing strategy applied for the API 5L line to research joint spillage. Different tests incorporate twist tests, smoothing tests, and so forth. The line pipe should be liberated from breaks, sweats, spills, or some other imperfections.
Other significant contemplations are:
- Resiliences on pipe measurements, divider thickness, out-of-roundness
- Normal imperfections
- Line pipe history and achievements
- Applications
- Pipe assignment
- Carbon identical cutoff points
- Jointer welds
- Closes type: plain, sloped, strung closes
- Fixes prerequisites
- Pipe markings and end tones
- CVN influence test
- DWT test
- Hardness test

Like other carbon steel pipes, the line thicknesses are not normalized for all API 5L line grades. The OD of lines matches the OD of other carbon steel pipes. Nonetheless, the thickness changes. Contingent upon high strength the thickness utilized for explicit applications is generally diminished. High strength and low thickness pipelines are generally utilized in the pipeline business.
Producers of API 5L lines give their timetable outline referencing the accessible line thicknesses for pipe size. The loads and costs per unit length are likewise ordinarily given in the API 5L line plan diagram. A few grades of line plans like API 5L grade pipes have normalized pipe plans as given in ASME B36.10. However, high-strength line pipes, for instance, X60, X52, X42, and so on have normalized as well as non-normalized pipe plans.
