Ball burnishing tool RShR-28 for pipe grids and manifolds

Ball burnishing tools RShR-28 for repair heat-exchange equipment

Ball burnishing tool RShR-28 is used to process the bore holes of pipe grids and manifolds before installing and rolling out the pipes to improve the tightness and joint efficiency.

After ball burnishing tool treatment three collars are formed on the surface of the hole. Then during the subsequent rolling of the pipe they are embedded into its outer surface thus ensure tightness and joint strength.

Ball burnishing tool RShR-28 allows you to adjust the distance from the pipe grid plane on which collars are formed.

Adjustment range from 3 to 30 mm.

The numerical index of model designation indicates the nominal pipe outer diameter for which pipe grids holes are machined. 

The axial spindle movement is provided by the manual force to the pneumatic control valve actuator (PKM-350) or is performed automatically (by the device МПРШ-2).
