API 5L X52 PSL2

What is API 5L X52?

X52 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. We are supplier & distributor of X52 Seamless Steel Pipe, X52 Welded ( ERW, LSAW, SSAW ) Steel Pipe made of Carbon steel and alloy steel according to API, ASTM, ASME, DIN standards strictly. High yield seamless Pipe API 5L grade X52 PSL 2 Suitable for weldable structural steels for fixed offshore structures.

API Spec 5L – Specification for Line Pipe, Petroleum and natural gas industries – Steel pipe for pipeline transportation systems. API 5L X52 Line Pipes are manufactured as per specifications established by American Petroleum Institute (API). This Standard specifies 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 is not applicable to cast pipe.

API 5L also requires a monogram license for Manufacturer, and it maintains the Composite Index of approved Manufacturer. This means that, at the request of a potential manufacturer, API will send auditors to the mill to ensure that they have the capability to meet the requirements of the standard. This would be similar to a franchise, but API has no financial benefit from the mill, and does not accept any liability for the actions of the mill or the performance of the product. 

API 5L GR.B PSL2 Carbon Black Steel Pipe advantages

• API 5L GR.B X52 PSL2 Carbon Black Steel Pipe is a continuous extrusion of the alloy,it takes advantage of true roundness of the circumference.
• Welded seam pipe invariably is not as round in the cross sectional area as a black steel pipe because the welded pipe is wrapped around another form before welding.
• The welding adds heat,and the equipment adds stress to hold the pipe together.This process introduces variables that allow for warping of the roundness.
• carbon steel pipe maintains the round cross-section, which is important during installation and the addition of pipe fittings.
• Although API 5L GR.B PSL2 Carbon Black Steel Pipe is the most expensive steel pipe, it is the most reliable with the fewest failure points. Because of this, pressure calculations are easier to perform because the weld quality is taken out of the equation.
• Another advantage to using API 5L GR.B X52 PSL2 Carbon Black Steel Pipe is its strength under loading.Empty pipe has a certain weight that must be supported over long spans.
• When that pipe begins transporting material, the weight of the material must also be taken into account.
• Carbon black steel pipe has strength benefits compared with welded pipe. Most pipe failures and leaks take place at the welded seam.
