Product Description

High Pressure Pipe Stopper Inflatable Pipe Plug Balloon Plug

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.
