Pipe beveling is the process of forming an angle (or chamfer)  on the end of a pipe or tube. It is commonly applied to prepare the end for welding, although it can also be used for deburring the cut ends for handling safety. 

These portable machines allow the tube to be machined on site and in-situ and are applied across the world in many industries including chemical, oil, gas, water, food and power generation.

These machines can also be used to remove welds between the tubes and tube sheets (or boiler plates) in heat exchangers or boilers prior to the removal of the tubes.

As the tubes of boilers, heat exchangers and condensers corrode and suffer damage from long-term use the tubes need to be periodically replaced. Tube Pulling systems (tube pullers) are designed for this task. Using Hydraulic power they break the seal and pull expanded tubes from the tube sheets. (or Boiler Plates). 

Typically this is done by driving a mandrel (also called a spear) into the tube inner diameter. A hydraulic ram with special attachments (also called a tube pulling gun) is loaded over the mandrel and grips hold of it.  As the ram extends it applies force to the mandrel which then acts to pull on the tube in order to extract it 

The hydraulic pump can be, electrically or pneumatically driven. The pulling force required varies with the tube size and wall thickness, the depth of the tube sheet and tube material. Stub pullers are also available to be used where tubes are cut behind the tube sheet leaving only the short tube ‘stubs’ to be removed.
