Bi-Direction Pig
This type of pig is designed and produced to separate two different fluids in pipelines from 4 to 56 inches. The double-sided pig is made of a metal body, and the seal and guide are made of polyurethane elastomers with high tensile strength and wear resistance. In double-sided pig, the weight of the pig is lighter. Because flood and guide replace all kinds of cups. This type of pig saves the time of testing and the amount of water consumed, and another advantage of this type of pig is the use of discs with a distance, which reduces the leakage coefficient and the possibility of reverse movement (reverse movement of the pig during the exit stages of the pig or Expelling a large volume of sediments is very useful and sometimes unavoidable in gas lines due to pressure fluctuations. This type of pig is for Filling & Dewatering operations. This type of pig is a combination of seal disc and guide disc, with the number of 2, 4 or 6 seal discs and a combination of brushes.
Applications
- It is used to empty pipelines of water in pressure (hydrostatic) testing.
- It is used to empty the fluid, to clean inside the pipelines.
- It is used to separate several dissimilar materials in multi-purpose pipelines.
- It is used to lower the line humidity in gas flows.
- These types of pigs cause more cleaning due to movement from both sides (two-way chasing).
- It is used to clean gaseous liquids and mud, sand and soot sediments from pipelines.
- It is used to pass 1.5D to 3D bend angles in pipelines.
Customization
