Two specialized product lines for pipeline blocking and local repair. Multi-layer reinforced composite rubber construction.
High-pressure inflatable pipe blocking airbags for pipeline isolation and flow control during maintenance operations.
Made of multi-layer reinforced composite rubber, stable high-pressure sealing for sewage pipeline maintenance. Guide wheels on both ends are optional, easy to send into long underground pipes, reusable with custom sizes.
Equipped with dual-end roller assemblies for smooth insertion and positioning in long underground pipes. Reduces friction and installation effort in extended pipeline sections.
Heavy-duty construction for large trunk sewers and main drainage lines. Reinforced body for extended blocking periods under full system pressure.
Inflatable packers for localized trenchless pipe repair, crack sealing, and joint rehabilitation.
Double-layer wear-resistant rubber structure, uniform expansion for local trenchless pipe repair. Fit pipeline crack and joint leakage repair, customized diameter and length available.
Longer packer body for repairing extended crack sections and multiple adjacent joints. Custom length manufactured to match defect dimensions.
Tailored diameter, length, and pressure rating for specific pipe repair applications. Engineering consultation and design support included.
Every product is manufactured to consistent standards using proven materials and construction methods.
Body constructed from multiple layers of reinforced composite rubber. Synthetic fiber reinforcement between rubber layers prevents ballooning and maintains dimensional stability under pressure.
Heavy-duty inflation valve with pressure retention. Standard Schrader valve compatible with common air compressors. Pressure relief protection included.
Guide wheels on both ends available for selected models. Galvanized steel or aluminum frame with sealed bearings. Facilitates insertion in long pipeline sections.
Every unit individually pressure-tested before shipment. Test pressure exceeds rated working pressure to verify seal integrity and material performance.
Our technical team can recommend the right model based on your pipe diameter, application type, and pressure requirements.
