LSAW Steel Pipe
Manufacturing procedure
In order to supply high quality LSAW steel pipe for our clients, we’ve established a highly sound and strenuous pipe production circulation. After the above-mentioned processes, begin the double-sided submerged arc welding.

Specifications Range
Out Diameter: 219mm-720mm( UOE),406 mm-1625.6 mm( JCOE).
Wall Thickness :max 65mm.
Length:3.0m-18m.

Production technology and equipment
By adopting newest advanced production innovations, we can produce LSAW steel pipe with diameters of over 610mm and wall densities of over 15mm. To be particular, the optimum diameter and wall density of our LSAW steel tube is 2150mm and 30mm respectively.

We utilize extremely advanced hydraulic bending devices to process our big caliber longitudinal immersed arc welded pipes. Our flexing machine is created in double connected structure, which can process pipelines with a maximum length of 16m, and can load an optimal pressure of 1600tons. Through processes, consisting of flexing, butting seams, internal welding, external welding, flattening and correcting the alignment of, our LSAW steel pipes can fulfill the standard requirements of UAS Petroleum Association.

So, if you have any LSAW pipe requirement, please do not hesitate to attempt our products.

Applications

By performing basic nondestructive detections on our LSAW tubes, we ensure that our tubes serve our customers well. Our LSAW steel pipelines are perfect pipelines for massive pipeline engineering, petroleum, water or gas transport and city pipe network building and construction.

Quality assurance

In addition to the LSAW pipe, our company produces a variety of other industrial pipelines, consisting of smooth steel pipe, anticorrosion steel tube, spiral pipes and ERW welded tube. Our CE certified commercial pipelines are well accepted by customers from United States, Canada, Switzerland, Italy, UAE, Syria and more. If you want any commercial pipelines or have any inquires about our pipes, please don’t hesitate to call us.

 


UOE SAWL PIPES.
The UOE mill features the most sophisticated technology and process, attains high production efficiency, steady product quality and is geared up with complete examination devices.
Prodution Line.

UOE mill adopts U & O forming, the formed pipes are bonded inside through 5 internal welding stations with three wires, and welded outside through 4 external welding stations with three wires.
