Cup pigs are designed to be used for pipeline cleaning, batching and gauging. The design is derived from the hydraulic piston and aggressively scrapes the pipeline bore while maintaining a good seal.
When encountering pipe ovality and varying pipe wall thickness, conical cup pigs are the most appropriate option as they allow maximum flexibility while maintaining a positive seal.
Our range of cup pigs is available in sizes from 2” up to 56” or 48” for conical cup pigs, with 2, 3 or 4 cup models and a variety of body constructions available.
- Brush pigs – designed to remove debris and deposits from the pipeline. The pigs are supplied with carbon steel, polypropylene or nylon brushes and offer excellent cleaning qualities. All of our brush pigs are provided with by-pass ports which allow removed debris to be flushed clear of the discs and brushes.
- Gauging pigs – designed to prove the pipeline is laid as specified, gauging pigs are vital to the pre-commissioning process. When combined with an Online Electronics GRID system, the approximate position of a defect in the pipeline can be established. The gauge plates are manufactured from 6mm thick aluminium and machined to the client’s specified order.
- Tracking Device Housing – All of our pipeline pigs can be designed to house an Online Electronics tracking device such as an acoustic pinger or electromagnetic transmitter. This enables quick and accurate tracking and locating of a stalled pig, resulting in significant savings in time and therefore cost.
- Magnets – Magnetic pigs can be used to remove ferrous debris from the inside of the pipeline or to operate magnetic non-intrusive signallers such as Online’s range of onshore, topside and subsea magnetic signallers.
