Fabric-reinforced inflatable pipe stopper – Sealing, Leak Testing & Pipeline Isolation
The fabric-reinforced inflatable pipe stopper is an essential tool for professionals in construction, wastewater management, industrial maintenance, and chemical processing. Versatile, flexible, durable, and easy to transport, this device allows you to temporarily block a pipeline, perform leak-tightness tests, or prevent the discharge of hazardous substances during sensitive operations.
Made from technical reinforced fabric, the stopper is inflated with air or nitrogen to perfectly fit the inner wall of a pipe — regardless of its material (PVC, concrete, cast iron, PEHD, steel, etc.).
Why choose a fabric-reinforced inflatable stopper ?
Unlike rigid or standard rubber models, the textile inflatable stopper combines mechanical strength with exceptional flexibility.
It is:
- Easy to insert, even in deformed or oval pipes.
- Resistant to aggressive chemicals, depending on the model.
- Perfectly suited for confined or contaminated environments.
- Reusable many times thanks to its reinforced construction.
Engineered for field technicians, it guarantees fast, reliable sealing in both dry and wet environments.
Typical applications of fabric inflatable stoppers
• Pressure leak testing
Used to hermetically seal a pipeline section, allowing air or water injection to perform a pressure test. These tests are essential for:
- New installations (wastewater, stormwater, or chemical networks).
- Periodic regulatory inspections.
- Projects in sensitive environments.
• Temporary blocking during maintenance
During repair or maintenance work, the stopper can be inserted upstream of the work zone, preventing the flow of liquids or gases into the intervention area.
• Pipeline isolation to prevent spills
In industrial or chemical settings, these stoppers are used to block pipelines containing potentially hazardous fluids, allowing safe drainage or maintenance operations.
• Emergency response for leaks or spills
In case of a leak, rupture, or accidental discharge, the technician can quickly insert and inflate the stopper to contain pollutants or prevent flooding in a critical area.
Technical advantages of inflatable fabric pipe stoppers
- Flexible and easy to install — adapts to pipes with irregular or variable diameters.
- High mechanical resistance — reinforced fabric withstands significant internal pressure.
- Chemical compatibility — suitable for various industrial fluids and chemicals.
- Time-saving — fast setup and removal on site.
- Compact for storage and transport — once deflated, it requires minimal space.
- Long-lasting — reusable dozens of times without performance loss.
Technical specifications of inflatable fabric pipe stoppers
Our inflatable stoppers are made from multi-layer technical fabrics (typically nylon coated with polyurethane or neoprene) ensuring:
- Excellent air tightness,
- High internal pressure resistance,
- Outstanding chemical durability.
Each stopper is equipped with a secure inflation valve (Schrader or industrial type) and can be used with:
- A flexible inflation hose,
- A pressure gauge or safety manometer,
- A retrieval rope,
- A portable compressor or compressed air/nitrogen cylinder.
Available in a wide range of diameters, these stoppers fit all types of pipelines — PVC, cast iron, steel, concrete, HDPE, and more.
Professional use instructions
- Clean the inside of the pipe if necessary.
- Insert the folded stopper into the pipe up to the target area.
- Gradually inflate using a compressor, pump, or gas cylinder.
- Monitor inflation pressure with a calibrated gauge.
- Leave the stopper in place for the duration of the test or intervention.
- Slowly deflate and remove after use.
⚠️ Safety note: Never exceed the recommended working pressure. Always ensure the stopper is properly centered to avoid any piston effect during pressurization.
