The high pressure variable diameter sealing airbag is soft and ductile, strong pressure resistance, good air tightness, high safety, long pressure time, convenient installation and removal, fast sealing speed, and can be used repeatedly. The high pressure variable diameter airbag is made of imported natural rubber and polymer aramid material, which has the characteristics of sustainable expansion. Our high pressure variable diameter air bag adopts mechanical die-casting integrated vulcanization mode, the rubber density is large, the pressure can be up to 0.25MPa, one specification of the air bag can be blocked different specifications of several pipelines, for example: DN300mm-600mm can be blocked 300-600 all specifications of pipelines. It is really time-saving, labor-saving, convenient, safe and fast.

The variable diameter pipe sealing airbag is suitable for different pipe detection, maintenance, water and air closure test. Applicable range of 150mm-1000mm pipe materials, metal parts in stainless steel. The product adopts the integrated vulcanization process, the rubber material is tight and the sealing is excellent. High strength, corrosion resistance, anti-aging, light weight, safer construction

The variable diameter sealing air bag is widely used in all kinds of pipeline water closing test, municipal pipeline maintenance, sealing, dredging, silting, water blocking, leakage blocking, drainage pipeline maintenance, sewage industry treatment, fire repair and blocking construction. The pressure of the air bag is high, and the personal safety of the downstream construction personnel is guaranteed after the pipeline is blocked.
