Cups & Discs are made of the highest quality polyurethane for maximum abrasion resistance, elongation, sheer strength and chemical resistance to assure the best performance under the largest variety of pipeline conditions.

Center-hole and bolt-circle dimensions can be customized to fit any pig body on the market, making them the ideal replacement cups and discs.

Cups & Discs are designed to maintain a positive seal while also supporting the pig body. Multiple durometers are also available for specific applications.

Various styles of both cups and discs are manufactured to traverse pipeline configurations including Long & Short Radius Bends, Tees, Valves, Varying Wall Thicknesses and even Dual-Diameters.

The standard cup and disc materials are urethane or neoprene. Cups and discs are also available in Nitrile, Hypalon, Viton. Urethane has outstanding abrasion resistance plus it is resistant to moderate chemicals, oils, fats, greases and many hydrocarbons. Neoprene has excellent abrasion resistance plus it is resistant to moderate acids and chemicals, ozone, oils, fats, many solvents and oily abrasions. Nitrile has good abrasion resistance but not as good as Neoprene. Nitrile is generally resistant to most hydrocarbons, fats, oils, grease, hydraulic fluids, chemicals and solvents. Hypalon has excellent abrasion resistance and is generally resistant to strong acids and bases, freons, hydroxides, ozone, alcohols, etching, alkaline and hypochlorite solutions. Viton has good abrasion resistance and generally resistant to all aromatic, aliphatic and halogenated hydrocarbons. Viton is also generally resistant to many acids, animal and vegetable oils. EPP has good to excellent abrasion resistance and is generally resistant to vegetable and animal fats, oils, ozone, many strong and oxidizing chemicals, ketones and alcohols.

CUPS

Cups are one of the types of sealing elements used by steel-mandrel pigs. They are designed to allow the pressure of the line to seat the outer sealing surface of the cup against the internal pipe surface to ensure positive seal. Cups are flexible so as to adapt to out-of-round or varying internal pipe diameters. Styles range from standard to conical, as well as special designs such as those for thin-wall pipes.

  • Conical Cup
  • Standard Scraper Cups
  • Thinwall Cups
  • Type A Cups
