C-Type External Clamping Pipe Beveling Machine

C-Type External Clamping Pipe Beveling Machine

The C-type external clamping pipe beveling machine is a portable pipe end preparation tool for small-diameter pipes. It is mainly used for pipe end beveling, cutting, end facing and welding preparation. The machine adopts an external clamping structure, so it does not need to be sleeved over the pipe end. This makes it suitable for installed pipelines, limited working spaces and on-site maintenance conditions.

The machine uses automatic feed operation and is simple to operate. By changing arc clamping fixtures of different sizes, it can cover pipe diameters from 14mm to 114mm. After clamping, the machine provides accurate positioning and helps improve bevel consistency while reducing manual grinding and on-site finishing time.

The C-type external clamping pipe beveling machine is suitable for carbon steel, stainless steel, alloy steel and other pipe materials. It can be used to prepare U-groove, single V-groove, double V-groove and other bevel forms. It is widely used in petroleum, natural gas, chemical, food, boiler, pharmaceutical, nuclear power, facility construction, industrial pipeline installation and on-site emergency repair projects.



  • Suitable for beveling, end facing and welding preparation of small-diameter pipes from 14mm to 114mm.
  • External clamping installation provides firm holding and is suitable for installed pipelines and field maintenance.
  • Compact and lightweight structure for narrow spaces, pipe racks, equipment rooms and repair sites.
  • Automatic feed design provides more stable cutting and reduces manual feed error.
  • Arc clamping fixtures can be selected according to pipe diameter for accurate positioning.
  • Suitable for carbon steel, stainless steel, alloy steel and other metal pipe materials.
  • Can prepare different bevel forms such as U-groove, single V-groove and double V-groove.
  • Used in petroleum, natural gas, food, boiler, pharmaceutical, nuclear power, industrial pipeline installation and emergency repair.
