Pipe Fittings, End Beveling

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.

Pipe Fittings End Beveling

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 acc. to

• ASME B16.9, Factory-Made Wrought Steel Buttwelding Fittings
• ASME B16.28, Buttwelding Short Radius Elbows and Returns
• ANSI/ASME B16.25, Buttwelding Ends
• MSS SP-97, Socket Welding, Threaded, and Buttwelding Ends

Welding Bevel acc.to ASME / ANSI B16.9 and ASME / ANSI B16.28

Our in-hourse R&D team developed bevel ends equipment are good using in thickness 2mm to 20mm pipe fittings, guarantee high efficiency and high quality.

Send us your technical drawings: SunnySteel will supply you with whatever flanges you are looking for.
