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.
