Specification

API 5L welded steel pipe types on oil pipelines include spiral submerged arc welded pipe (SSAW), longitudinal submerged arc welded pipe (LSAW), and electric resistance welded pipe (ERW).


There are many grades of raw materials for API 5L steel pipes like: GR.B, X42, X46, X52, X56, X60, X70, X80, etc. ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2).


Pipeline pipes should be subjected to water pressure tests one by one, and the standard does not provide for non-destructive substitution of water pressure. This is also a big difference between API standards and Chinese standards. API 5l psl1 does not require non-destructive inspection, API 5l psl2 should be non-destructive inspection one by one.


Applied for petroleum and natural gas industries, oil industries requirements for transportation and are expected working in extreme situations, low and high temperatures, corrosion resistance for corrosive environments, and for sour services in H2S conditions.

Process

There are 3 welding types: ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types.

ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe in two different manners as listed below. Based on the welding frequency, the IF welding for low frequency and the ultra-IF welding for high frequency. In case of thin-walled pipe, there is a high frequency weld used typically in case of contact welding and induction welding. When the usage is for a small-diameter pipe, they make use of DC welding. There is a high frequency welding process used to manufacture pipes that are comprehensive and is of ERW type. For oil and gas storage, the best recommended type is ERW longitudinal, owing to its quality, ease of transport and cost.

Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe. Owing to the flux layer, there is no instant heat loss and it gets concentrated near the weld. It results in high quality, highly efficient arc and smoke, which finds intensive usage in pressure vessels, pipe manufacturing, beams, fluids, steel works etc. SAW pipe find its main usage in LSAW pipe, which is Longitudinally Submerged Arc Welding pipe.
