Logiball - Collapsible Mainline Sewer Packers for Injection Grouting
FromLogiball Inc.
Collapsible Mainline Packers are designed for testing and sealing pipe joints 24 inches and larger. These injection grout packers can be fully dismantled to pass through openings as small as 21 inches in diameter, then quickly reassembled once inside the pipe.
A soft natural-rubber sleeve is securely fixed to the support shell, covering both end bladders to ensure optimal seating and sealing, even against rough or irregular surfaces.Most popular related searches

These large diameter test and seal injection packers are equipped with large wheels for easy movement through the pipe. For better guidance, an extra set of wheels can be added without requiring any modification to the packer.
A sensitive bladder transmits the chamber pressure through a line to which a gauge or a transducer can be installed. The two chemical ports are protected by large non-clogging adjustable rubber check-valves. They avoid dripping of the chemical grout components and syphoning the tanks while providing added safety against backflow contamination into the hoses.
- Available up to 144″. Custom designs for box culverts and other shapes are available.
