Inflatable Pipe Plugs

High-Pressure Inflatable Pipe Plugs 

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.

Our professional-grade blocking inflatable pipe stoppers are special designed for municipal, commercial, high-pressure, or large diameter pipes. The inflatable pipe plugs are ideal for large pipes where access is limited. When deflated, they can be folded up and inserted through a standard manhole, then inflated. Industry-leading plugs are tough yet flexible and lightweight. Their easy handling makes these plugs the first choice among installers.

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.

We are proud to provide the highest quality plugs, together with expert service and timely customer support. Ask us about any of our plugs for commercial or municipal usage including inflatable test plugs and pneumatic pipe plugs. Let’s help you successfully complete your project – on budget and on time.

PVC Inflatable Pipe Plugs

DOOWIN inflatable pipe plugs are flow stoppers for temporary close off or seal an opening. Our inflatable pipe plug/stoppers are very suitable for use in the pipeline, ducts, and tunnels with construction, inspection, repairs, cleaning, and repair. 

Our inflatable pipe plugs are constructed of high tenacity, urethane coated nylon fabric. We also make it with other special coating material and synthetic-tire-cord rubber layers. This ensures our inflatable pipe stoppers are resistant to fuel, petro-chemicals, and other caustic chemicals. Each inflatable pipe plug is equipped with rigging hardware, inflation ports, and pressure relief valve.

DOOWIN inflatable pipe plugs are multi-size flow stoppers. Each flow stopper can be used to close off a range of pipe-diameter. The inflatable pipe plugs are easy to install and as even more important easy and quick removed because of its lightweight.

The common size is from DN300 to DN3000. Custom sizes, shapes, and configurations can be designed and manufactured to meet special needs.

Each inflatable pipe plug is tested before delivery.
