812.8mm LSAW Steel Pipe | IBC (Tianjin) Industrial Co.,Ltd

IBC (Tianjin) Industrial Co.,Ltd produce 812.8mm LSAW Steel Pipe for decade years. LSAW (Longitudinal Double Submerged Arc Welding, also called SAWL pipe) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology.

Usually LSAW steel pipe have one single and straight weld seam. But the O.D. larger than 914.4mm LSAW could prefer two straight welding seams. It can also called dsaw steel pipe.

LSAW Pipe is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing. When compared UOE vs JCOE pipes, LSAW steel pipe manufacturers in China can produce more sizes as below:

LSAW Pipe for Pipelines

Firstly, we take testing for the basic metal and welding metal according to the specification of pipe API 5L Spec. Meanwhile, we have other Specifications standard. Such as DIN, EN, ASTM, and GOST. Also, the LSAW steel pipe can welded with flanges and other fittings. Such as welding lifting eyes and other parts according to clients’ requirements. Secondly, It also can used as pipe boots or pile boots which acted as protecting a section. Finally, Except used as pipe boots. The LSAW steel pipe is also used for transporting fluids like water, oil & gas. As well as used for offshore projects and underground constructions. These products are producing in China. And exported to other countries. For example Australia, Canada, South American, Europe, Malaysia, India, Pakistan, Africa, etc.

Conclusion

LSAW steel pipe base on its advantage of high reliability and safety performance, the LSAW pipe is widely used in various pipelines engineering and construction, even under the most severe condition, and also can be used in engineering of chemical industry, electric power, irrigation, construction and piling etc.

IBC Metal Group could supply all sizes of LSAW Steel pipe. 812.8mm LSAW steel pipe is common used sizes when using for offshore projects. If you need more information, please do not feel hesitate to contact with us.
