Description
Coating Foam Pig is a foam pig. Its main material is polyurethane foam. Its surface is coated with a layer of polyurethane. This structure makes it not only cleans the pipeline but also has corrosion resistance.
The diameter of polyurethane foam pig is generally 1.75 ~ 2 times the pipe diameter. Its interference is generally 5%~10% of the pipe diameter. Therefore, it has high elasticity, toughness, and certain wear resistance. And the deformation of this product is more than 50%.
The foam pig is so soft that it can pass through the elbow very smoothly. Even in case of pipe blockage, this product can pass through. Or the user can increase the pressure in the pipe to break the product. The user can then remove the pipe blockage. In this way, accidents will not occur due to excessive pressure. Moreover, the debris of the foam pig will not damage the inner wall of the pipeline. Therefore, the product is suitable for cleaning pipes with inner wall coating.
“Coating Foam Pig” is mainly used for pipeline cleaning
(water, gas, oil, chemical reagent, and other media).
- Natural gas pipeline in operation: it can remove the internal water, light oil, methane hydrate, iron oxide, carbide dust, carbon disulfide, sulphuric hydrogen acid, and other corrosive substances, and reduce the corrosion damage of corrosive substances to the inner wall of the pipeline; Redefine the pipeline route; Detect pipeline deformation; Check the intactness rate of valves along the line; Reduce the working back pressure.
- Operation of Zhongyuan Oil Pipeline: pigging before pipeline inspection, pigging of oil pipeline with low throughput and intermittent operation; Remove the condensate, wax, and scale inside the pipeline to reduce the oil back pressure, wear-resistance, and oil temperature.
- Water transmission and injection pipeline: it can be used to remove scale, sediment, etc.
