SSAW Pipes, Spiral submerged-arc welding pipes,Spiral Submerged-arc Welded steel pipe, Manufacturer and ExportersSpiral 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.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+500mmIn addition to above specification, the pipes can be produced according to customer's requirements.Execute Standard:ASTM A252-89 WELDE AND SEAMLESS STEEL PIPE PILES API SPEC 5L Specification for Line PipeGB/T9711.1 Petroleum and natural gas industries-Steel pipe for pipelines-Technical delivery conditionsSY/T5037 Spiral submerged arc welded pipe for low pressure liquid transportationMaterial:Q235-Q345, L175-L485, SS400, 16Mn, L290-L360or according to the customer's requirements.Mainly usage:Spiral welded steel pipes are widely used in Oil, Natural Gas, Water and other flammable & nonflammable liquid conveyance and distribution pipelines, steel structures for construction and other general purposes by means of their wide size range.Pipe Coating: HDPE/ 3PE/ 3PP/ Pipe cement mortar liningMill Test Certificate: EN 10204/3.1B Third party inspection: SGS, BV, Lloyds etc.
