Our inflatable pipe plugs are engineered to deliver reliable, high-pressure sealing for a wide range of pipeline maintenance, testing, and repair operations across multiple industries.
1. Municipal & Urban Pipeline Management
● Drainage & Sewer Maintenance: Provides temporary isolation of pipe sections during cleaning, inspection, or repair, preventing flow interference and enabling safe work conditions.
● New Pipe Pressure & Leak Testing: Used for water-tightness and pressure tests in newly installed pipelines, ensuring compliance and system integrity before commissioning.
● Rainwater/Sewage Separation Projects: Enables precise sectioning of pipelines during system upgrades or separation projects.
2. Industrial & Infrastructure Projects
● Water Conservancy & Hydraulic Engineering: Temporary blocking for maintenance of water channels, culverts, or outflow pipes in dams, reservoirs, and irrigation systems.
● Highway & Bridge Drainage Systems: Isolates drainage pipes under bridges or along highways for inspection and repair without disrupting traffic flow.
● Industrial Pipeline Stoppage: Used in factory drainage, chemical effluent lines, or HVAC condensate pipelines for safe downtime maintenance.
3. Emergency Response & Rehabilitation
● Pipe Rehabilitation Lining Projects: Seals pipes during cured-in-place pipe (CIPP) lining or other trenchless rehabilitation methods.
● Emergency Leak Containment: Rapid deployment to temporarily contain leaks or overflows in damaged pipelines before permanent repair.
As a factory specializing in pipeline solutions, we ensure every plug meets rigorous standards for durability, safety, and ease of use.
1. Robust Design & Performance
● High-Strength Rubber Material: Manufactured from reinforced, pressure-resistant rubber with excellent elasticity and recovery, ensuring a tight seal even under high-pressure conditions.
● Secure Locking & Anti-Slip Design: Textured surface or integrated straps prevent slippage in smooth or sloped pipelines, maintaining position during operations.
● Rapid Inflation/Deflation System: Compatible with standard air pumps for quick deployment and retrieval, reducing downtime and labor effort.
2. Manufacturing & Quality Assurance
● Industrial-Grade Materials: Resistant to sewage chemicals, UV exposure, and abrasion for extended service life in harsh environments.
● Precision Vulcanization Process: Ensures uniform thickness, strong seam integrity, and consistent inflation behavior across all products.
● Pressure-Tested & Certified: Each plug undergoes pressure holding tests and is rated for clear working PSI ranges, with compliance to industry standards where applicable
3. Operational Efficiency & Cost Effectiveness
● Reusable & Long-Lasting: Designed for multiple deployments across projects, reducing per-use cost and waste compared to disposable alternatives.
● Versatile Sizing Range: Available in multiple diameters and lengths to fit pipes from small drainage lines to large municipal culverts.
● Easy to Clean & Store: Smooth surface allows for easy cleaning after use; deflates compactly for convenient transport and storage.
● Multi-Section Pipeline Isolation: Ideal for sealing across joints, irregular surfaces, or pipes with obstructions where standard plugs may not fit securely.
● Bridge Deck & Expansion Joint Sealing: Used in infrastructure projects where linear or segmented sealing is required along channel spans.
● Custom Configurations: Can be tailored in length and link design for specialized engineering needs.
