Awwa C200 Steel Water Pipe 8 inch And Largewater Transmission Ssaw Steel Pipe
The strength of SSAW spiral welded pipe is generally higher than that of straight seam welded pipe, and larger diameter welded pipe can be produced from narrower billets, or different diameters welded pipe can be produced from billets of the same width.SSAW Steel Pipe (Spiral steel tube) is a spiral welded steel tube made of strip steel coil as raw material, usually formed by warm extrusion, and welded by automatic double-wire double-side submerged arc welding process.
The spiral steel tube feeds the strip into the welding tube unit, and after rolling with multiple rollers, the strip is gradually rolled up to form a round tube blank with open clearance. TWeld seams.The pipe manufacturer shall request information regarding welding procedures from the plate or sheet manufacturer if the pipe manufacturer lacks experience in welding the material selected. All welding shall be performed in accordance with The sheet or plate manufacturer’s recommendations for preheating and the type of electrode to be used.
End welding. All end welding of longitudinal seams of fusion-welded pipe, if not done by automatic submerged-arc or automatic shielded-arc welding, shall be done by an operator qualified in accordance with Sec. 4.11.3.1.4.11.2 Automatic welding. All longitudinal, spiral, and girth seams of straight pipe sections and special sections, when practicable, shall be welded with an automatic welding machine. On request, sample welds shall be submitted to thepurchaser for testing.Qualification. Automatic welding operators and procedures shall be qualified under Sec. IX, of the ANSI/ASME Boiler and Pressure Vessel Code, or under AWS B2.1, or under any other code mutually agreed on between the purchaser and manufacturer.
