The inflatable pipe blocker revolutionizes pipe leak testing for plumbing and sanitation professionals. This inflatable plug effectively isolates sections of pipe for rigorous leak testing without the risk of leakage.
What is an inflatable pipe blocker?
An inflatable pipe blocker is a temporary sealing device designed to hermetically seal a pipe. Consisting of a durable rubber membrane and an inflation system, this pipe blocker is positioned in the pipe and expands to create a perfect watertight barrier.
Professionals mainly use it for:
- Isolate sections during leak tests
- Perform localized repairs
- Monitoring pressure in networks
- Securing maintenance operations
Inflatable Sealing Plug User Guide
Preparation before installation
Before use, thoroughly inspect the inflatable plug. Check that there are no tears in the membrane and test the inflation system. Carefully clean the section of pipe where the pipe blocker will be positioned to avoid any risk of perforation.
Installation procedure
Carefully insert the deflated plug into the pipe until it reaches the desired position. Connect the inflation system and gradually increase the pressure. Monitor the inflation carefully to avoid overpressure, which could damage the membrane or pipe.
Once inflated, perform a preliminary leak test by applying light water pressure. If no leaks are detected, proceed with the full leak test in accordance with current standards.
Secure withdrawal
To remove the plug, slowly and completely deflate it. Gently pull it out of the pipe. Clean and dry thoroughly before storing.
How to choose the right shutter diameter?
The choice of diameter is crucial to the effectiveness of the inflatable plug. An unsuitable diameter compromises the seal and can damage the equipment.
Accurate measurement of inner diameter
Measure the inside diameter of your pipe accurately using a tape measure or caliper. For non-circular pipes, use the smallest diameter. Add a 10% safety margin to compensate for irregularities.
Size chart
Inflatable plugs generally cover several diameters. For example, a 100-150 mm model fits pipes with an internal diameter of 100 to 150 mm. Always choose a model whose range includes your diameter with a comfortable margin.
Professional applications and benefits
Sewage companies make extensive use of these pipe blockers for their work. During lining work requiring epoxy resin cartridges, the inflatable plug perfectly isolates the work area.
For comprehensive diagnostics, it can be effectively combined with an HD inspection camera to view the condition of the pipes before and after the intervention.
Economic benefits
The use of inflatable plugs significantly reduces intervention costs:
- Quick installation without excavation work
- Multiple reuse of equipment
- Reduced response times
- Accuracy of leak tests
Maintenance and service life
Regular maintenance ensures the longevity of your inflatable sealing plug. After each use, clean thoroughly with clean water and a mild detergent. Dry completely before storing in a dry place, away from direct light.
Regularly inspect the membrane for any micro-cracks. Immediately replace any shutter showing signs of weakness to maintain safety during operations.
Standards and safety
Professional inflatable plugs comply with European standard EN 1610 for pipe leak testing. They generally withstand pressures of 0.5 to 1 bar, which is sufficient for most sewerage applications.
Strictly adhere to the maximum pressures specified by the manufacturer. Overinflation can cause the membrane to burst, with dangerous consequences for the operator.
