API 5L Seamless Steel Linepipes are usually used to transfer oil ,gas or water to the industrial end users. They often go through special machining process to receive a threaded, shouldered or plain end.

API 5L Seamless Steel Linepipes is similar to that of ordinary seamless pipes in production process. The main difference is that the API 5L Seamless Steel Linpipes should be tested strictly according to API standard.

3 Specification range:

OD: 3''-24'' (73mm-610mm)

WT: SCH10-SCHXXS

4 Materials: 10#, 20#,45#,16Mn, GRB, Q345B, X42-56, ST44, ST52 etc.

5 Testing: Eddy current, Hydrostatic, Ultrasonic, Intergranular corrosion etc.

6 Packing: in bundles with steel strips, seaworthy packing as per customer's requirements

7 Application: Hot-rolled seamless steel pipes are widely used in fluid transmission such as petroleum, natrural gas, coal gas, waster as well as shipbuilding, large constructions, machinery, chemical fertilizer equipment, electricity industry etc.
