API 5L GR.B LSAW Epoxy Resin Steel Pipe


The API welded steel pipe is essentially an oil or natural gas line pipe that has been sent through ERW, LSAW, or SSAW process. It has been tested to and complies with the API 5L standard.

The main purpose of the API welded steel pipe is to convey oil, gas, or water to the end user. The pipe comes with one of the three types of ends: plain ends, threaded ends, or socket end. Correspondingly the joining method can be butt welding, threaded, or socket welding.


1. Welded: 1 1/2"-100" ( 48.3-2540mm)
2. Material: L210-450,GrB, X42-70 etc.
3.Standards: API 5L
4. Testing: eddy current/hydrostatic/ ultrasonic/ intergranular corrosion.
5. Packing: seaworthy packing
6. Application: for water, oil and gas transmission, ship-building, mining etc.
