Welding Procedure for API 650 tank - Storage tank

RE Welding Procedure for API 650 tank IFRs (Petroleum) 12 Mar 14 17:12 9.3.2 The welders and welding operators who weld pressure parts and join nonpressure parts,such as all permanent and temporary clips and lugs,to pressure parts shall be qualified in accordance with Section IXWater Tower Specialists - InstallationThe studs do not undergo any loss of length after welding.Arc stud welding is a welding process where the gun solenoid lifts the stud from the metal surface and creates an arc which melts a flux-loaded end of the stud and its immediate area.A ceramic ferrule shields the arc,concentrates the heat and contains the molten metal in the weld zone.Vertical tanks for petroleum products storageThe Saratov Reservoir Plant produces vertical cylindrical tanks for petroleum products storage with a volume of up to 100,000 m 3 with a pontoon,floating or fixed roof.Oil tanks construction They are vertical cylindrical tanks of different height and diameter for storing up to 100,000 m 3 of bulk liquids.
