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.
