API 5L X52 Carbon Steel Pipe

The inner and outer surface of API 5L X52 Carbon Steel Pipe does not allow wrinkles,fold,fold tie,separation,scarring and oxide etc.The defects should clean off totally.Removing defects should be smooth and polished,Depth of cleanning shall not exceed the negative deviation of  nominal wall thickness,The actual thickness of defect clearance should not less than the allowrance of minimum wall thickness,it should not be filled up with welded
The inner and outside surface must be polished
The oxide on inner and outer surface should be removed,API 5L X52 Carbon Steel Pipe are no need for paint and other anti-corrosion treatment
The solder joint are not allowed on the interface of carbon steel pipe
The shape of two ends should be cut at right angles and clear the glitch
The tolerance of dimention of API 5L X52 Carbon Steel Pipe
Diameter and ovality
The tolerance of diameter:+/0.01D,The maximum is not exceed than +/-4mm
The tolerance of ovality:0.02D,The maximum is not exceed than10mm
The tolerance of wall thickness-5%-+20%,Average wall thickness of each pipe shall not be less than the specified wall thickness
