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.

HDPE pipe High-density polyethylene jacket tube is widely used in oil pipelines, gas pipelines, urban heating pipes, water pipes, electricity and other corrosion engineering, product quality and service by the users of a good level. 3PP Anti-corrosion pipe Three-layer PE/PP coating is characterized by excellent corrosion-proof performance,insulatibity,relatively long service life and mechanical damage resistance.

DSAW pipes Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. SAW pipes 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 The 3PE Coating Steel Pipe enjoys good impact resistance, abrasive resistance, shock resistance, acid resistance, high quality and long service life. Pipe cement mortar lining Cement mortar lining can ensure a safe and abundant water supply for your water customers for many years to come. Success Stories 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.
