WHAT IS API 5L PIPE/ API STEEL PIPE?

API steel pipe used for transmit gas, water, and oil in Offshore Industry, Oil & Gas Projects, Oil Equipments & Instruments, Petroleum Services Companies, Oil Field Services Companies, Rig Industry: Oil & Gas Drilling & Exploration etc.

The American Petroleum Institute specification API 5L addresses seamless and welded steel line pipe for pipeline transportation systems in the petroleum and natural gas industries.

Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, standardizing pipeline transportation systems within the materials, equipment and offshore structures for natural gas, petroleum, and petrochemical industries. When authoring the standards, the technical committee recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2. PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.

API steel pipe covered by few grades and specification including A25, A, B and “X” Grades X42, X46, X52, X56, X60, X65, X70, and X80. The two digit number following the “X” indicates the Minimum Yield Strength (in 000’s psi) of pipe produced to this grade.

API 5L Seamless Pipes

Seamless pipes/ tubes, API 5L carbon steel pipes are made by rolling a preheated billet between offset rolls to create a tube shell. The tube shell is then elongated in a multi-stand rolling mill (with a mandrel) to achieve the desired wall thickness and a limited range of diameters. API Tube diameter can also be achieved with a sizing collar, but for significant diameter changes the tube is reheated and passed through a stretch-reducing mill – a multi-stand mill that reduces outside diameter but not wall thickness. The seamless range also includes Oil Country Tubular Goods (OCTG.)

API Boiler Tubes/ boiler tubing, the oil and gas industries and automotive transmission components are typical applications.

API 5L Welded Pipes

Welded pipes/ tubes are made from hot rolled or cold reduced strip, sheet or plate. Welded tube includes hollow sections, black and galvanised gas/water pipe, scaffolding tube and large diameter pipe. Small and medium diameters are produced in continuous, multiple-roll mills that progressively bend incoming, unheated strip into a circular cross-section prior to welding along the longitudinal seam. Tube may subsequently be cold-drawn through dies to achieve precise dimensions and finish. Large diameters (400-1,600mm) are made from discrete plate which is welded in an “O” shape before being mechanically or hydraulically expanded. API Spiral welded tube/ Pipes is available in diameters up to 2,500mm.

API Welded tubes are used in a wide range of general engineering applications as well as in power generation plants, oil refineries, automotive manufacturing and furniture production.
