Steel Body Pigs

Steel-Body pigs, or Mandrel pigs, are heavy-duty pigs which can be configured in a number of ways to provide maximum cleaning, sealing and sweeping power. These pigs can travel long distances and the urethane cups and discs are replaceable which makes them an economical option for many pipeline operators.


The 4 disc 2 brush configuration is a cleaning pig that is typically used for the removal of paraffin, black powder, bacteria and other unwanted debris. Pigs can be modified to meet specific job requirements.  

  • Sizes: 4” – 36”
  • Disc Materials: Urethane, Neoprene, Nitrile
  • Brush Materials: Carbon Steel, Stainless Steel, Prostran
  • Brush Types: Round Wire, Flat Wire, Pencil Brushes
  • Magnets, gauge plates and transmitter mounts are available.

The 4 disc configuration is a cleaning and dewatering pig that is used for the removal of solids and liquids when tight radius bends are present in the line. Pigs can be modified to meet specific job requirements. 

  • Sizes: 4” – 36”   
  • Disc Materials: Urethane, Neoprene, Nitrile
  • Magnets, gauge plates and transmitter mounts are available.

The 6 disc configuration is a cleaning and dewatering pig that provides a great seal. Great pig to use for nitrogen purges, batching and the removal of solids and liquids. Pigs can be modified to meet specific job requirements. 

  • Sizes: 4” – 36”                   
  • Disc Materials: Urethane, Neoprene, Nitrile
  • Magnets, gauge plates and transmitter mounts are available.

The 5 disc 2 cup configuration is a superior sealing pig that is used for the removal of liquid and unwanted debris. The multiple sealing elements allow this pig to be effective on long runs, perform great on nitrogen purges as well as clean aggressively. Pigs can be modified to meet specific job requirements.  

  • Sizes: 4” – 36”
  • Disc/Cup Materials: Urethane, Neoprene, Nitrile
  • Magnets, gauge plates and transmitter mounts are available.

The 5 disc 1 brush configuration is an aggressive cleaning pig that is typically used for the removal of paraffin, black powder, bacteria and other unwanted debris. Pigs can be modified to meet specific job requirements. 

  •  Sizes: 4” – 36”   
  • Disc Materials: Urethane, Neoprene, Nitrile
  • Brush Materials: Carbon Steel, Stainless Steel, Prostran
  • Brush Types: Round Wire, Flat Wire, Pencil Brushes
  • Magnets, gauge plates and transmitter mounts are available.

The 3 disc 2 cup configuration is a great sealing pig that is used for the removal of liquid and unwanted debris. The multiple sealing elements allow this pig to be effective on long runs, perform great on nitrogen purges as well as clean aggressively. Pigs can be modified to meet specific job requirements. 

  • Sizes: 4” – 36”   
  • Disc/Cup Materials: Urethane, Neoprene, Nitrile
  • Magnets, gauge plates and transmitter mounts are available.

The 2 disc 2 cup 1 brush configuration is an excellent cleaning pig that is typically used for the removal of paraffin, black powder, bacteria and other unwanted debris. The cups provide a great seal while the discs and brush scrape and remove any unwanted debris. The brushes Pigs can be modified to meet specific job requirements. 

  • Sizes: 4” – 36”                   
  • Disc/Cup Materials: Urethane, Neoprene, Nitrile
  • Brush Materials: Carbon Steel, Stainless Steel, Prostran
  • Brush Types: Round Wire, Flat Wire, Pencil Brushes
  • Magnets, gauge plates and transmitter mounts are available.

The 2 disc 2 cup configuration is a great all around pig. The discs provide good debris removal and the cups provide a great seal and long wear. Pigs can be modified to meet specific job requirements. 

  • Sizes: 4” – 36”
  • Disc/Cup Materials: Urethane, Neoprene, Nitrile
  • Magnets, gauge plates and transmitter mounts are available.

The Enduro Dual-Diameter Pigs are designed to withstand the heavier wear due to multi-dimensional pipe. This pig provides cleaning action and has proven to hold a great seal through multi-diameter lines. Design may be varied to specific line needs; i.e. bend radius requirement, valve bowl lengths etc. and can also be outfitted with brushes specially designed for multi-diameter cleaning.

Enduro's pig train employs the Pig Link concept which allows various configurations and adaptations of cups, discs, and body links. The flexibility of the polyurethane body link allows the pig to pass bend radius as small as one diameter even when attached to additional link sections.

TDW's PitBoss™ Cleaning Pig is designed to remove soft to medium-hard deposits from internal pits while also serving as an excellent general purpose cleaning pig.

WCK Pigs come equipped with tempered steel wire brushes and urethane cups. The dual diameter WCK Pigs for cleaning multiple sizes of pipe are equipped with steel wire brushes and discs. An outlet port at the front end of the WCK Pigs provides fluid bypass to prevent piling of loosened material.
