Weld beveling for flange and fitting

Butt weld fittings is one of the most popular connection type in pipeline systems. It always been required in large quantities in different industries, and especially for the large diameter pipelines.

What is Butt Weld Fittings
Butt weld is to connect pipes or fittings ends by welding. It’s a weldable steel pipe fitting that would allow to branch off, allow for change of direction of flow, attach auxiliary equipment, or reduce the size of the pipe.

We aware the beveling is very important processes in the whole production procession of butt-welding pipe fittings, we always make beveling according to the standard strictly. In the behavior, we make beveling after shot blasting, bevel ends are fully machined by advanced equipment Double Beveling Machine ensure the height, length, thickness, O.D. and I.D. are all qualified.

Welding Bevel on Piping system following below codes:

  • ASME / ANSI B16.9 Wrought Fitting (Elbow, Reducer)
  • ASME / ANSI B16.5 Pipe Flanges (up to 24 inch)
  • ASME / ANSI B16.47 Pipe Flange (up to 60 inch)
  • ASME / ANSI B16.25 Butt welding ends (General application, NOT apply to B16.5, 16.9 Products)
  • MSS SP-97
