What are the specific differences between flexible pipes and rigid pipes?
The rigid waterproof sleeve is used in the wall of the building which does not need to bear the vibration and expansion deformation of the pipe, and the wall thickness is 200mm in general;Flexible waterproof sleeve is mainly applicable to the wall of buildings with seismic requirements, pipeline vibration and expansion deformation, and strict waterproof requirements, and the wall thickness is 300mm
Choose from the waterproof performance:A rigid waterproof sleeve is a steel pipe with an outer wing (a steel ring made of a steel ring), mounted in the wall (mostly concrete walls), used for general pipe wall crossing, and is beneficial to the waterproof of the wall;The flexible waterproof casing except external wing ring, flange ring and internal wire like, and have complete sets sold, but also their own processing, for pipeline damping needs, such as pipes and pumps connected through walls.
Watch from outside:The rigid waterproof sleeve is made up of steel bushing and wing ring, and the structure is simple;The flexible waterproof sleeve mainly consists of flange sleeve, sealing ring, flange, pressure plate, wing ring, bolt and nut. The structure is complicated.
Structurally:A rigid waterproof sleeve is welded with a water stop ring outside the steel pipe;The flexible waterproof casing pipe is welded on the outside of the 3 side wing ring, 4 screw buckle, inside a welding piece with a rubber ring, the outside and do a flange, with 4 double head bolt, welding a steel pipe, the pipe installed, the flange is installed. The screw fastening, tightening the apron is bigger, more Water Leakage, generally in the waterproof requirements of relatively high places, such as the pool of water.
From the model:Rigid waterproof sleeve: A, B and C, A type, suitable for steel pipe, B, suitable for cast iron pipe and ductile iron pipe;Flexible waterproof bushings: A and B, A used in the internal walls of buildings, B used in the exterior walls of buildings.In use:
