Longitudinal Submerged Arc Welded Pipe (LSAW Steel Pipe)
The longitudinal submerged arc welded pipe (LSAW steel pipe) is characterized by superior welding. Outstanding properties and performance of our longitudinal seam welded steel pipe have been amazingly appreciated in West-East Gas Pipeline Project. This is one of the major natural gas transmission projects in China. The total length is 4,000km, and pipeline diameter is 1,016mm. The conveying pressure is 10Mpa.
Advantages
1. Our longitudinal seam SAW pipe involves the utilization of JCOE manufacturing method for uniformed stress resistance.
2. Our industrial conveying pipe is available in a wide range of sizes and materials such as Q235-Q690 series and GR.A-X80 grade steels. Maximal O.D. reaches 1500mm and the maximal W.T. is up to 60mm.
3. This longitudinal seam fluid conveying pipe has been extensively applied as petro casing pipe and constructional pipe, and is well-suited for power plant, water treatment, central air-conditioner and mid to low pressure flammable fluids.
Classification
Our LSAW steel pipe can be supplied in accordance with different standards from all industrial sectors.
This welded pipe is highly recommended for industries of construction, bridge and power plant, etc.
