Polyurethane Cup

With the rapid development of industries like petroleum, chemicals, urban water supply, and natural gas transport, the demand for pipeline descaling, wax removal, and anti-corrosion coating equipment is increasing, along with higher quality requirements for pipeline cleaning. To reduce costs and extend cleaning lengths, the traditional black rubber used in pigging cups can no longer meet production needs. Therefore, developing a new material for pigging cups with high hardness, excellent elasticity, superior sealing, and wear resistance is crucial. Polyurethane is the ideal choice due to its excellent performance.

Polyurethane pigging cup seals have the following key features:

1. High Hardness and Elasticity:

   Polyurethane offers high hardness and good elasticity, ensuring thorough cleaning and improved pipeline performance.

2. High Strength and Tear Resistance:

   With high tensile and tear strength, polyurethane seals are ideal for removing weld beads without damage.

3. Oil and Solvent Resistance:  

   The seals provide excellent resistance to oil and solvents, ensuring effective anti-corrosion protection for new pipelines.

4. Long Service Life:  

   Durable and wear-resistant, these seals can clean pipelines over 80 meters in a single run, reducing processes and saving costs.

5. Excellent Sealing Performance:  

   With low liquid adsorption, these seals offer superior sealing, especially during degassing and hydrostatic testing.
