SOLID CAST PIGS
- Solid Cast Pigs are made in one piece using specially formulated elastomers with superior physical properties, usually polyurethane.
- Primarily used for product removal, batching, hydrostatic testing, and paraffin, debris or other buildup removal.
- They are capable of making longer and more efficient runs, able to negotiate tight radius bends as well as varying internal diameters of the same size pipe.
- Solid Cast Pigs are available in dozens of designs and configurations to suit your application.
BARE FOAM, LOW-DENSITY PIG
UTILITY:
- For use in Low Volume, Low Pressure pigging
- 2 lb. Density Foam coated with polyurethane elastomer on end
- Used for drying and sweeping of loose debris in pipelines that have low volumes and pressures present
- Pigs oversized 3-5 % of pipe ID, and approximately 1.5 times the pipe diameter
- Customized diameters and lengths available
POLYURETHANE SPHERE PIGS
UTILITY:
- Constructed of high-grade abrasion and chemical resistant solid-cast polyurethane material
- Inflatable type has hollow core, which can be filled with liquid and pressurized up to 2% of standard diameter for proper fit in pipeline
- 2" thru 4" are available in solid type only. And 6" thru 48" are available in inflatable type.
- The U-53 (yellow) is primarily used as a meter prover sphere in sweet crude oil, heating oils, gasolines, jet fuels, natural gas liquids, butanes and propanes as well as other refined products that are not aromatics
- The U-58 (green) is generally used in natural gas pipelines to remove liquids. It can also be used for general pigging of liquid pipelines.
- The U-66 is used in harsher sphere applications. The construction material is more rugged, minimizing blistering and molecular deterioration.
- Options include neoprene, viton, epdm, buna-n or other elastomer compounds for special services; varying durometers (hardness); sphere-filling pump and accessories; customized sizing for special pigging applications
