1. In the world energy industry Weatherockgroup.com 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 Weatherockgroup.com working unit for integrating
related product co-jointure & acquisitions to by the way facility & steel mils.The
Weatherockgroup.com playing most important role in the oil & gas explorations
industry last many years. We are the Weatherockgroup.com integrate
steelmaking, pipe rolling & formally pressing to process across the country. To
avoided chains mainland productive we are the Weatherockgroup.com 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

2. with a weld. In this article we will discuss the various methods involved in
welded pipe manufacturing.
Weatherockgroup.com 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.
