The Mandrel Pigs’ cups and disc are available in Polyurethane, Neoprene and Nitrile in various durometers for superior scraping and sealing. They attach to the Mandrel Pig either through a center-hole for smaller sizes (standard 3” thru 14”) or bolt-hole circles for larger sizes (standard 16” and up). The number of cups and discs as well as their arrangement can be customized to accommodate certain application and desired results. This gives the Mandrel Pig the ability to overcome some of the most difficult pipeline obstacles such as short pipeline bends, tees and multi-diameter pipelines.

The ability to add Brushes, Magnets, Gauging Plates and other options to the nearly limitless configurations of the Mandrel Pig make it an excellent choice for pipeline cleaning, batching, gauging, displacement, bi-directional, dual-diameter, hydrostatic testing and removal of paraffin and scale build-up.

Steel pigs are a more long-term, long-life pig. They consist of a steel mandrel body with easily replaceable sealing elements (cups and discs) and can be equipped with various brush types (spring-loaded, circular, wrap-around) for removing deposits on the interior pipe wall. Standard configurations include cup, disc, multi-disc, conical cup, and various combinations. Various options are also available, such as adding or substituting a cup or disc, special lengths and diameters, gauging plates, articulated joints, transmitter cavities, and magnet packs. The advantage of steel pigs is the ability to replace the wearing components (cups, discs, brushes, etc.), thereby rendering it a new pig.

Displacement Pigs (Disc Type)

Disc displacement pigs are used for standard pigging operations such as filling and dewatering during hydrostatic testing, routine batching operations, product removal, or any pigging operation requiring bidirectional use. These pigs are also very effective for product separation. They are available in sizes from 2″ through 48″ with configurations including 2-disc and 4-disc as standard. They can easily be equipped with a gauging plate and used to prove pipe roundness and to ensure excessive weld penetration or debris does not exist, as well as prove minimum bend radius prior to intelligent pig use.

Batching Pigs (Cup Type)

Cup-type batching pigs are used for standard pigging operations such as filling and dewatering during hydrostatic testing, routine batching operations, and product removal. They are available in sizes from 2″ through 48″ with standard designs of 2-cup, 3-cup and 4-cup. When equipped with a gauging plate, they are used to prove pipe roundness and to ensure excessive weld penetration or debris does not exist. Batching pigs are also used to prove minimum bend radius prior to intelligent pig use.

Brush Cleaning Pigs

Brush cleaning pigs are used during pre-commission and on-stream cleaning where rust, mill scale, sand, wax, organic growth, mud, oxides, and other foreign matter exist. Sizes range from 2″ through 48″, with brush configurations including wire wheel, split-ring, wrap-around, and spring-loaded.

ARP Brush Cleaning Pig

ARP Brush Cleaning Pigs consists of a carbon-steel body (bolting pattern configuration type) equipped with two (2) easily replaceable polyurethane cups, one (1) easily replaceable polyurethane disc, and leaf-spring mounted brush assemblies. Options and other configurations include carbon-steel, stainless-steel or aluminum body; cups manufactured from neoprene, viton, epdm, buna-n or other elastomer compounds for special services; carbon-steel, stainless-steel, prostran brushes, or polyurethane blades; aluminum or steel gauging plate of varying thickness (available with slots); transmitter or pinger cavity; magnets for ferrous debris or for magnetic detection; customized dimensions for special pigging applications.

  • Magnets
  • Brushes
  • Gauging Plate
  • Bypass Holes
  • Custom Diameter
  • Custom Length
  • Combination of cups and discs
  • Replaceable Components

Multi-disc Pigs

The multi-disc series of pigs allow for excellent sealing capabilities for performing the duties of batching, gauging, product removal, pre-commission and on-stream cleaning, or any pigging operation requiring bidirectional use. When equipped with a gauging plate, the pig is used to prove pipe roundness and to ensure excessive weld penetration or debris does not exist. Multi-disc pigs can also be used to prove minimum bend radius prior to intelligent pig use.

Articulated Pigs

Articulated pigs are primarily used in small-diameter applications (6″ to 14″) with tight-radius bends. Articulated pigs are connected in the center with a urethane chain (a solid steel chain molded in urethane). They are equipped with brushes for cleaning operations such as pre-commission and on-stream cleaning where rust, mill scale, sand, wax, organic growth, mud, oxides, and other foreign matter exist. Various brush designs include wire-wheel, split-ring, and spring-loaded, as well as polyurethane blades. When equipped with a gauging plate, the pig can be used to prove pipe roundness and to ensure excessive weld penetration or debris does not exist. Articulated pigs can also be used to prove minimum bend radius prior to intelligent pig use.

Dual-Diameter Pigs

With their unique design, both dual-diameter and multi-diameter pigs are capable of negotiating varying diameter piping configurations that other pigs cannot. Available in sizes of 3″ x 4″ and larger, they can also be equipped with brushes for cleaning operations.

Note: As with all special pigging applications such as dual-diameter or multi-diameter projects, it is best to discuss in more detail the characteristics of the pipe to determine the best-suited pig and/or pigging method.

Conical Cup Pigs

Conical cup type batching pigs are used for standard pigging operations such as filling and dewatering during hydrostatic testing, routine batching operations, and product removal. They are available in sizes from 2″ through 48″ with standard designs of 2-cup, 3-cup, and 4-cup. Conical cup pigs can also be equipped with brushes, blades, or gauging plates, allowing it to perform all the duties of batching, gauging, hydrostatic testing, product removal, pre-commissioning and on-stream cleaning. The conical cup design allows for negotiation of varying internal pipe diameters and up to 15% reductions or deformations in nominal same size pipe. Conical cup pigs can be easily configured with discs in lieu of cups, or adding guide, sealing and spacer discs for additional sealing capabilities.
