HepcoMotion products are used extensively in the offshore industry, often having to work under extreme conditions underwater or above water in areas exposed to the elements. Many applications require a ring to be located around a pipe for pipeline inspection systems, welding and cutting processes. HepcoMotion PRT2 rings allow precise and rigid guidance around the periphery of any circular shape.
This application requires a pipe to be fed through a stationary ring to a stop position for a cutting process. The conditions will be hostile causing possible contamination of the ring V surfaces. The carriage travelling around the ring will need to move smoothly at a consistent rate to ensure an accurate cut and long cutter life.
A double edge V ring from the PRT2 range with an integral rack provides the qualities required for this application. Rings are available in diameters from 93mm to 1.6m so a typical 700mm diameter pipe can be accommodated easily. The special carriage has a motor to provide the drive for the system to rotate around the pipe and a separate one for providing power to the cutter.
The wiping action of the V bearings running on the V ring will be vital in ensuring that the swarf from the cutting process does not cause possible jamming of the system. Systems with the benefit of V technology will provide increased system life in comparison to other bearing technology.
