    20 nominal pipe size (NPS) the chosen wall (0.322) may not be larger than 1.14 times the smallest measured wall, in our case 1.14 x 0.330 = 0.376. For pipe 20 or more use 1.11 in place of 1.14. Technical requirements for Pipes - What Is PipingButt weld elbows shall be long radius type (radius =1.5 nominal pipe size). Short radius elbows are not permitted. For reducing fittings specified with two schedules in the Inquiry / Purchase description, the first schedule refers to the larger end or run pipe, the second schedule refers to the smaller end or branch pipe.

    The advantage and the application of butt welding pipe

    Application of butt welding pipe fittings. The butt welding pipe fitting end is connected to the end of pipes or fittings by butt welding joint, it may also be connected to weld neck flange.The d iameter and thickness of the pipes and fittings ends should be in the same size and schedule and materials.The butt welding joint cound be installed by manual or machine welding and inspected after Welding Pressure Pipeliners and Piping Systems Depending on the pipe size, a half round file can be used to remove any burrs created when the land is ground on to the end of the pipe. Welding the Root Pass Before beginning to weld the pipe, the procedure should be checked to assure that the correct electrode is being used. This includes the diameter and the classification of the electrode.
