API 5L line pipes can be divided into two grades:API 5L PSL1 and API 5L PSL2.PSL is short for Product Specification Levels.Both levels of API 5L line pipes contain seamless steel pipe and welded steel pipe and used of a pipeline in the transportation of petroleum and natural gas.There are some details you should know about API 5L PSL1 & PSL2:
API 5L PLS1 & PLS2 Manufacturing Technique:
Cold Drawn Steel Pipe
Hot Rolled Steel Pipe
Hot Expanded Steel Pipe
API 5L PLS1 & PLS2 Steel Grade:
Grade B ,X42,X46,X52,X56,X60,X65,X70
API 5L PSL1 Grade B seamless steel pipes
API 5L PLS1 & PLS2 Pipe Size:
Outer Diameter: 1/8″-36″(10.3mm-914.4mm)
Wall Thickness: 1.2mm-80mm
Length: Random Length,SRL,DRL(4-14M)
End: plane ends beveled ends
Surface: Bare, Black,Lightly oiled, Hot dip galvanized,, Varnish coating/Anti rust oil, Protective Coatings, 3PE
Packing: Nude, Plastic/steel plugs in both ends, Hexagonal bundles of max. 2,000kg with several steel strips, Two tags on each bundle, Wrapped in waterproof paper, PVC sleeve, and sackcloth with several steel strips, Plastic caps.
Third party inspection: SGS,BV,ABS etc.
