API, shorted for American Petroleum Institute, is considered as one of the most authoritative and comprehensive principles for oil and gas industry. Products complied with API standards are always thought of reliable quality. Under the general standards, there are some subordinated specifications drafted for each specific OCTG product, such as API 5B, API 5CT, API 5D, API 5L and so on.
API Line Pipe is steel pipe used for the transmission of Oil, Gas and Petroleum Distillates.
Line pipes makes the pipeline and is different from casing and tubing.
Line Pipes are manufactured as per specifications established by American Petroleum Institute (API). API 5L is a specification of API which defines the standard for the dimension, physical, mechanical and chemical properties of the steel. Several pipe mills around the globe manufacture the API 5L pipes for Oil and Gas industry.
Reliable Steel Distributors manufacture and exporter the API line pipe which is required to transport natural gas, crude oil, liquid gasses from producing field to refinery. We manufacture line pipe as per API 5L standard which is supported by our USP of world class quality, committed delivery period, better service at a most competitive price.
MSL API 5L line pipes come in a variety of sizes and wall thickness manufactured in India, to meet our customer’s requirement. We offer both ERW and Seamless to meet the challenge of all transmission conditions.
Reliable Steel Distributors as an API Line pipe manufacturer in India is the leading name across the world. We are the one stop solution for our wide range of products. MSL has established himself as a most trusted brand, especially in the oil and gas sector.

In API SPEC 5L 46th Edition, the standard scope is defined as: “Requirements for the manufacture of two product specification levels (PSL1 and PSL2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. This standard does not apply to cast pipe.”
To summarize, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system. Meanwhile, other fluids such as steam, water, and slurry can also adopt the API 5L standard for their transmission purposes.
The API 5L welded pipe common types are as follows:
ERW: Electric Resistance Welded, for pipe diameter normally under 24 inches.
DSAW/SAW: Double Submerged Arc Welding / Submerged Arc Welding, a substitute welding method of ERW for larger diameter pipes.
LSAW: Longitudinal SAW, for diameter up to 48 inches. Also called the JCOE manufacturing process.
Seamless manufacturing type is usually for small diameter pipes (typically under 24 inches).
(When the pipe diameter is less than 150 mm or 6 inches, the seamless steel pipe is more commonly applied than the welded steel pipe.)
There are also seamless pipes of large diameters. By using hot rolled manufacturing process, we can get seamless pipes with diameters up to almost 20 inches (508 mm). If you need seamless pipes with diameters above 20 inches, we can make them through hot expanding process, with maximum diameters up to 40 inches (1016 mm).
