Introduction
In sewer pipeline maintenance, quick and efficient blockage is crucial to prevent wastewater leakage and ensure safe working conditions. The inflatable rubber plug (also known as a pneumatic pipeline stopper) offers a fast, reliable, and reusable solution for temporary pipeline sealing during repair operations.
Advantages of Inflatable Rubber Plugs
1. Quick Installation: The plug can be inserted and inflated within minutes.
2. Strong Sealing Performance: High-pressure resistance ensures a tight seal even in pressurized pipes.
3. Reusable & Cost-Effective: Unlike traditional methods (e.g., cement bags or mechanical plugs), rubber plugs can be reused multiple times.
4. Versatile Applications: Suitable for various pipe diameters (DN 100–2000 mm) and materials (PVC, concrete, HDPE).
Construction Process
l Inspection & Preparation
l Check pipe diameter and select the appropriate inflatable rubber plug.
l Clean the pipe interior to ensure proper sealing.
l Insertion & Positioning
l Insert the deflated plug into the target section using a guide rope or robotic crawler.
l Align it precisely at the repair point.
Inflation & Sealing
l Connect an air compressor and inflate the plug to the recommended pressure
l Verify the seal by checking for water leakage.
l Maintenance & Deflation
l After repairs, slowly deflate the plug and remove it for future use.
Conclusion
The inflatable rubber plug provides an efficient, economical, and eco-friendly solution for sewer pipeline repairs. Its rapid deployment and strong sealing capability make it a preferred choice for modern pipeline maintenance.
