The Red Bare Squeegee is an effective pig to run for liquid removal after a hydro-test. It has also proven to maintain a superior seal when flow rates are minimal. The bare squeegee is available in both medium and high foam densities and can be outfitted with magnets or a cavity for tracking purposes.

The Knapp Nova-Cast Pig is a custom-designed, all-urethane, one-piece, composite pipeline pig made to accommodate special pipeline configurations with virtually limitless combinations of discs and cups of varying urethane hardnesses. The Nova-Cast is available in configurations that allow the pig to pass through multiple-diameter piping while retaining the ability to scrape paraffin or remove liquids.

This criss-cross polly pig is made with 5# foam density and is an economical and safe way to pig your lines. The criss-cross urethane coating provides extra durability and allows the pig to travel longer distances without being damaged. This pig can also be outfitted with pull ropes and cavity for transmitter device.

This pig is a solid-cast polyurethane pig available for 2” through 8” pipe. It is a bi-directional pig ideal for use in plant and industrial applications. The 8 sealing discs making it very effective in removing liquids in wet gas systems and liquid lines, as well as ideal for product batching, line displacement, and product evacuation.

This foam pig is made from soft foam and is capable of light sweeping and cleaning. The light coat of urethane makes it more wear resistant to weld slag thus allowing the pig to make longer runs than an uncoated swab pig.

This criss-cross polly pig is made with 9lb foam density which is stiffer and more aggressive than the 5lb criss-cross pig. Like the 5lb foam pig, this one can be used in many ways including, cleaning, batching and de-watering. The criss-cross urethane coating provides extra durability and allows the pig to travel longer distances without being damaged. This pig can also be outfitted with pull ropes and cavity for transmitter device.

This pig is a solid-cast polyurethane pig for 2” through 36” pipe. It is available in up to three different durometers for varying projects. The 5 sealing discs and a rear cup design is extremely effective in removing liquids in wet gas systems and liquid lines. The hollow core makes the pig lightweight and uses the line pressure to expand the pig helping to create a superior long lasting seal. This superior sealing capability make it ideal for product batching, line displacement, and product evacuation. Wire Brushes may be added when more aggressive pigging is required as well as transmitters for pig tracking.

The standard Ultra-Seal Pig has flat, polyurethane elastomer discs on each end. This is the optimum design for dewatering, batching of dissimilar products, and for fluid removal in pipelines of all sizes and pipe materials.

The Ultra-Seal Lite Pig is a hand-crafted, custom-built pig. The specific design and materials for each pig are determined by the configuration of the pipeline and operational requirements of the pig. Typically the Ultra-Seal Lite Pig is used for dewatering and fluid control in multi-dimensional pipelines.

This solid-cast polyurethane pig is designed for 2" through 30" pipe and available in up to three different durometers. The unique cup design allows smooth transition with full wall seal through tees, check valves and full opening valves. The hollow core allows expansion while under pressure for maximum performance at all times and may be used to house transmitters for pig tracking. Bolt on wire brushes are available when more aggressive cleaning is required. The Turbo Magnum is effective in removing liquids from wet gas systems and liquid pipelines. Also used to control paraffin build up in crude oil lines, separation of refined products, pipeline commissioning and product evacuation.
