Double Submerged arc Welded (DSAW) Pipe Manufacturer Longitudinal Welded Pipe Ma

 In the world energy industry is the leading industry till from 10 years. Above the all of costumers are belong from the world top leading oil & gas company .We have the expertise group of engineer to design  & constructing oil & gas exploration transportations procedure  to facilitations  of all costumer.

Since in 2007 we are the working unit for integrating related product co-jointure & acquisitions to by the way facility & steel mils.The playing most important role in the oil & gas explorations industry last many years. We are the integrate steelmaking, pipe rolling & formally pressing to process across the country. To avoided chains mainland productive we are the playing most important role to create one global networking for originally anti – dumping.

To convey product one place to another place industry mainly use steel long & hollow pipes. As per produced mainly by two distinct manufacturing methods which result in either we get a welded pipe or seamless pipe. Double Submerged Arc Weld in the manufacturing method raw steel is first cast into a more workable starting form (hot billet or flat strip).From 1970 we started as small plant chain with the production in some item welded pipe. Now we are developing & manufacturing more complete product in so many option  as example Double Submerged Arc Weld, Longitudinal Welded Pipe, HFW steel pipe, Seamless Tubes Manufacturers ,pipeline valve & fittings, drilling completions,  casing & tubing ,drilling pipe ,down trolled motor  .

Then it can be made into a pipe by stretching the hot steel billet out into a seamless pipe or forcing the edges of flat steel strip together and sealing them with a weld. In this article we will discuss the various methods involved in welded pipe manufacturing. is ruling manufacturer company of Double Submerged arc Welded (DSAW) Pipe.A variant of the submerged arc welding process by the double submerged arc welding  which is the work piece being welded through a consumable electrode that call  double submerged weld. Other industries that use the double submerged arc welding include any that involve the joining of thick plates such as heavy equipment, mining, or infrastructure projects such as bridges.. One pass of submerged arc welding takes place on one side of the material, and another pass takes place on the opposite side of the first pass Double submerged arc welding is commonly used in the oil and gas industry to make large diameter pipelines.

In Longitudinal Submerged Arc Welding (LSAW) Prepare, longitudinal edges of steel plates are first beveled through using carbide milling equipment. Bevelled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press. Longitudinal edges of the plates are then tack welded followed by internal and external welds. Pipes manufactured by this process are subjected to expanding operation in order to relieve internal stresses and obtain a perfect dimensional tolerance. After the pipes are conveyed to cold expansion, hydrostatic testing and NDT inspection, the pipes will be subject to final inspection.

The LSAW pipe diameter range is larger than ERW, normally from 16 inch (406mm) to 60 inch (1500mm). Good performances on high pressure resistance, and low-temperature corrosion resistance.
