Replacement Parts for Steel Mandrel Pipeline Pigs
- Custom, no standard size
- Cast solid polyurethane, not foam
- Conical cups are available with a variety of wear-resistant additives
- Resists chemicals, wear—lasts longer than rubber cups
-
As a China manufacturer and supplier of pipeline pigging components, we make custom polyurethane conical cups using a custom high-performance polyurethane and super wear-resistant formulation. Our Pipeline Pig Cups are liquid cast for precision, ensuring they adapt to 20% pipe diameter changes and maintain seals in long runs or out-of-round pipes. Each pig conical cup undergoes strict tear and abrasion testing .
Our Polyurethane Conical Cups serve oil/gas , chemical (corrosive fluid batching), and pipeline maintenance (anomaly traversal) industries. They integrate seamlessly with most metal mandrel bodies for displacement, cleaning, and batching operations.
Customization Options:
ustomization Parameter Available Options Industry/Application Scenario Polyurethane Blends - Oil & chemical resistant
- Water and weather resistantPipeline pig cups for oilfield ; chemical-resistant pig conical cups for refineries Wear Additives - Standard abrasion resistant
- Very abrasion resistant polyurethaneEnhanced-additive polyurethane conical cups for long-distance pipeline runs Size 4″–36″ diameter (fits most pig bodies) 8″ for out-of-round gas pipes; 16″ for crude oil Hardness (Shore A) 70A–95A (flexibility-seal balance) 75A pig conical cups for pipe anomalies; 85A for displacement operations Mandrel Compatibility Carbon Steel/304 SS/Aluminum 304 SS-matched polyurethane conical cups for marine pipelines Advantages & Features of Polyurethane Conical Cups
