Foam Pigs which are molded from open cell Polyurethane Foam pigs ( either TDI or MDI & ester or ether based) with various configurations of solid polyurethane strips and or wire bristles, studs, etc., permanently bonded to them. Foam Pigs are available from sizes ½” to 72”.
Foam Pigs are widely used in the Pipeline Industry, especially for rehabilitation work. They are also particularly useful when developing a Pigging programme for a line which has not been regularly Pigged & which may contain some unexpected problems.
Being of Cylindrical shape, they contact the wall over their entire length & this reduces the unit loading.
- Low Density Bare Foam Pigs - Wiping or Drying Pigs The low density Bare Foam pigs is fully bare without any coating on its surface & has only coating with PU elastomer at its bottom or covered with Rexene Fabric depending the end use. Low density is a range from 16 to 32 Kg/cbm ( 1 to 2 lbs/ cft )
- Medium density bare foam Pigs are made out of Medium density – 80 to 96 Kg/ Cbm ( 5 to 6 lbs/ cft) used for regular wiping & dewatering.
- This medium density foam provides excellent wear resistance shall be used for long distance wiping or dewatering applications.
- High density foam Pigs are made out PU Foam pigs with density from 128 to 160 Kg / cbm ( 8 to 10 lbs/cft). Used for heavy wiping & dewatering, heavy duty applications with excellent wear resistance..
- Ultra High density foam Pigs are made out PU Foam pigs with density from 240 - 320 Kg / cbm ( 15 to 20 lbs/cft).Which provides excellent wear resistance shall be used for long distance wiping heavy wiping & remove the dense deposits of scale.
Bare foam Pigs
- Bare foam Pigs are made out of Medium density – 80 to 96 Kg/ Cbm ( 5 to 6 lbs/ cft)/ High Density - 128 to 160 kg/ Cbm used for regular wiping & dewatering.
- This foam Pig is coated on the surface with Polyurethane elastomers & used for heavy cleaning & dewatering
Fully coated Foam pigs
- This medium density foam Pig is fully coated hence provides excellent wear resistance shall be used for long distance wiping or dewatering applications.
Criss Cross coated Foam pigs
- The coating on this Pig is made on criss cross pattern used in Regular Cleaning & Dewatering applications.
- This foam Pig is coated on the surface with Polyurethane elastomers in a criss cross pattern & used for heavy cleaning & dewatering.
Silicon Carbide Strip Pasted Foam pigs
- Silicon Carbide Strip Pasted Foam Pigs. This Pig surface is coated with Polyurethane elastomer & strips of silicon carbide abrasive are pasted on the surface for tight bonding to be used for Heavy scraping of the scales from the pipeline internal diameter.
