Spiral submerged-arc welding pipes

Spiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral.

We are manufacturer of SSAW pipes and supply high quality SSAW pipes in both large and small quantities worldwide and offer you the best prices in the market. 

We have a team of experienced professionals with years of experience in manufacturing.

DSAW pipes
Double Submerged arc welded pipe
Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications.
SAW pipes
Internal Threaded Tubes
SAW is normally operated in the automatic or mechanized mode, however, semi-automatic (hand-held) SAW guns with pressurized or gravity flux feed delivery are available.
3PE steel pipe
3PE corrosion structure: the surface of the steel and epoxy powder electrostatic spraying adhesive side wound, lateral wound polyethylene coating, combined with the excellent performance of the three, thus significantly improving the overall quality of pipeline corrosion.
The 3PE Coating Steel Pipe enjoys good impact resistance, abrasive resistance, shock resistance, acid resistance, high quality and long service life.

Success Stories
Construction Machinery
Widely preferred longer lengths up to 18,5 m. considerably decreases the cost of pipeline construction resulting in less number of girth welds compared to shorter pipe lengths.
SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89 standard. These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction.
Size:
(O.D×Wall Thickness)mm×Length(mm)
219-3200mm×5-30mm x 12000mm+500mm
In addition to above specification, the pipes can be produced according to customer’s requirements.
