iNPIPE PRODUCTS™   welding pig design utilises the uniquely patented tyre design to provide proven reliability. Systems from 6″ up to 48” have been designed, manufactured and progressed through full factory acceptance testing. The innovative design can be used as a single tool in isolation or alternatively designed as a pig train.

About: Welding Pig – Piggable Plug

iNPIPE PRODUCTS™ welding pig design utilises the uniquely patented tyre design to provide proven reliability. Systems from 6″ up to 48” have been designed, manufactured and progressed through full factory acceptance testing. The piggable plugs are provided with 2 sets of inflatable tyres to provide fail-safe proven performance and reliability and ensure that the differential breakout pressure is uniform.

The system can be tailored to suit the specific needs of client requirements in terms of retaining pressure together with the required breakout pressure. Designs to “pig out” following isolation over a distance of 370km have been accommodated, however, the modular design could be modified to travel further distances as required.

The iNPIPE PRODUCTS™ welding pigs can also be supplied with a pipe insertion tool to aid insertion into the line pipe without the need for a launcher or reducer. The hydraulic insertion equipment is based upon our fully tried and tested, patented wet buckle insertion tool technology for insertion.

The design of the welding pigs is completely flexible and can also be modified to accommodate subsea installation by divers or ROV as required and independent of water depth as specific buoyancy of the pigs and/or insertion tools can be accommodated within the scope of design.

An additional benefit of the system, based around the widely acclaimed and specified iNPIPE PRODUCTS Dual Tool™, is that dependent upon positioning the tool can be used as a differential pressure barrier, a tool for the provision of inert gas to improve weld quality or subsequently a hydrostatic testing tool.

The iNPIPE PRODUCTS™ innovative design can be used as a single tool in isolation or alternatively designed as a pig train based upon specific project requirements.
