Advantages

3× faster work – no welding or mechanical fastening; just inflate to seal.

50% cost saving – eliminates temporary blank plates, flanges and welding labor.

Top choice for emergency – inflatable rubber pipe plug installs under flowing water, minimizing shutdown loss.

Detailed picture

*Municipal sewer repair – quickly shuts off damaged section for zero-leak maintenance.
*Water-supply networks – isolate upstream flow before valve replacement while keeping downstream service.
*Chemical pressure lines – oil-resistant seals fuel pipes to prevent spillage.
*Precast pipe testing – inflate plugs at both ends of RC pipe for internal hydrostatic pressure test.
*Subsea cable ducts – corrosion-resistant temporarily seals PE duct openings in seawater.
