High Pressure Inflatable Pipe Plugs 300mm DN For Pipeline Blocking

Inflatable Pipe Plugs Rubber Airbags High-pressure Pipeline Blocking

Based on years of experience in the production of marine rubber airbags, our company has successfully developed a new generation of high-pressure pipeline blocking inflatable pipe plugs. The inflatable pipe plugs are widely applicable to all kinds of pipeline closed water tests, municipal pipeline maintenance, plugging, dredging, dredging, water blocking, leaking, drainage pipeline maintenance, sewage industry treatment, fire emergency repair, and plugging construction, etc. The new type of blocking inflatable pipe stopper has the advantages of soft and tough texture, strong pressure resistance, good air tightness, anti-cracking, abrasion resistance, explosion-proof, convenient and quick operation, fast blocking speed, and can be used repeatedly.

Municipal series blocking pipe stoppers are the industry leader in employing advanced rubber compounds and high tensile fiber, with advanced integral winding production technology. Our pipe stopper is more flexible and lightweight, higher safety factor, stronger wear-resisting and anti-aging, and better sealing effect than the competition.

We do the airtightness and pressure test for all pipe plugs at a higher pressure than their working pressure to ensure durability and safety. We supply all necessary accessories together with the inflatable pipe plugs. The workers can use it directly after getting the plugs.

Applications

• Pipeline closed water tests
• Municipal pipeline maintenance
• Plugging, dredging, and water blocking
• Leak repair and drainage maintenance
• Sewage industry treatment
• Fire emergency repairs

Construction

The high-pressure inflatable pipe plugs feature:

• Airbag body with two cone ends
• Traction pull rings at both ends
• Inflation port at either end

Key Features

• High-quality rubber and synthetic-tire-cord construction
• Lightweight yet extremely durable
• Flexible design for difficult installations
• Reinforced for extra durability
• Pressure tested above working pressure
• Complete set of accessories included
• Conforms to almost any pipe configuration
• Compact when deflated for easy insertion
