Installation process of flexible waterproof casing, installation process photo of flexible waterproof casing, photo of flexible waterproof casing, analysis of five differences between rigid waterproof casing and flexible waterproof casing
: the rigid waterproof sleeve is a seamless steel pipe plus a wing ring (the ring made of thick steel plate is set on the seamless steel pipe), installed in the wall (often seen in the concrete wall), used for general pipe passing through the wall, is conducive to the waterproof of the wall; Flexible waterproof sleeve apart from the outside of the wing ring, there is also a gear ring such as the inside of the flange, direct wire, a complete set of equipment to sell, but also their own production and processing, with shock absorbers must be used for the pipeline, such as and centrifugal pump connection pipe through the wall. In other words, if consider the waterproof characteristic of metope double-sided, need to use flexible waterproof casing; If it is to consider the pipe to pass the wall only, and do not consider after passing the wall, the waterproof characteristic of metope double-sided and its pipeline migration deformation, can use rigid waterproof casing. The key point of flexible waterproof sleeve is to be used in the areas with high regulations such as civil air defense wall and reservoir. The rigid waterproof sleeve is generally used in the basement of villas and other places where pipelines should pass through.

Second: the external viewing rigid waterproof casing is only composed of steel waterproof casing and wing ring, simple structure, flexible waterproof casing key by: flange waterproof casing sealing ring flange clutch pressure disc wing ring anchor bolt nut structure complex.

Third: on the application of rigid waterproofing casing used in not responsible for the building of the pipeline vibration and collapsible deformation of the wall inside, and generally available flexible waterproof casing wall thickness is 200 mm in seismic provisions shall be applicable to the key pipeline vibration and collapsible deformation have sealed waterproof provision of housing construction the metope inside and generally available on the wall thickness is 300 mm from the specifications points: rigid waterproofing casing points: A type B type C type, type A is available with seamless steel tubes, type B available cast iron pipes and ductile iron pipe flexible waterproof casing points: Type A, type B, type A is used on the inside and outside walls of A building.

Fourth: rigid waterproofing casing is made of seamless steel pipe welding on a water stop wing ring outside, flexible waterproof casing is a seamless steel pipe welding on outside 3 wing ring, one side has four turnbuckle, welding inside a block slice, add a rubber ring, outside to do a flange, bolts in four sides, overhead welding a seamless steel pipe, the pipe mount after, put the flange on the screw, the greater the tight rubber ring, the less water seepage, generally in a waterproof rules with relatively high region, such as tank drain.
