API 5L Line Pipe

API 5L pipe is a kind of carbon steel pipe, which is specialized in oil and gas project. The production process as follows:

Raw material Test→ Uncoiling → Strip leveling →End Cutting → End Shearing and Welding → Accumlator → Forming →Telepathy Welding →Seam Heat Treatment →                              Air/Water Cooling → Body/Seam UT →Sizing Straightening → Cutting → Visual and Dimension Inspection →Hydraulic Test→ End Beveling →Flatten Test→ Seam/End UT →Length-Measuring and Weighing →Coating-Marking → Storage

Outer Diameter: 21.3mm-----630mm
Wall Thickness: 1.5mm----14mm
Length: 5m-----18 m

API 5L line pipe is widely used in oil and gas transportation project. The material of this kind of pipe can endure special environment such oil and natural gas. And they also meet the requirement of pressure so that they can transfer gas and oil successfully.
