Submerged Arc Welded - Saw Pipes

SAW or Submerged Arc Weld, as the name suggests, is a manufacturing method for large diameter Welded Pipes. SAW pipes are mainly are classified into Helical / Spiral SAW (HSAW) and Longitudinal SAW (LSAW). Generally large diameter pipes from Size 12¾” (324mm) onwards can be manufactured in LSAW construction and Size 16” (406mm) onwards in HSAW construction.

 

SAW are manufactured as per various standards and specifications like the Indian Standards IS3589,IS1978,IS2129,IS5504 American Standards like ASTM A53, API 5L (up to X80), AWWA C – 200, ASTM A134, A139, A252, A381, A589, A671, A672, A691, A1005, and British Standards BS7191. SAW pipes are usually used by various industries and for various applications viz. Oil & Gas, Hydrocarbon & Process Industry, Water & Sewerage, Piling, Structural or industrial applications like the mining and dredging etc.

Carbon Steel SAW Pipe manufacturing facility consists of a JCO Press, Helical / Spiral Mills, number of Three Roll Plate Bending Machine, Inside & Outside welding lines, Heat Treatment Furnace and all necessary Testing Equipment to produce high quality pipes conforming to various International Standards. These facilities are capable of manufacturing pipes in various grades.

The pipes are supplied according to appropriate standards as well as customer specifications in a large variety of steel grades and dimensions. Specific requirements on execution, tolerances, lengths, and mechanical & chemical properties are offered on request.
