Flexible waterproof casing used in civil engineering and water, warm pipe wall mounted, wall is conducted before construction of embedded parts, water supply and drainage pipeline wall of flexible waterproof casing embedded job requires strict control of the axis of the casing, installation of elevation, position, size, quantity, material whether to conform to the requirements of the design drawings, specifications, etc. Flexible waterproof casing, in the construction with large diameter and long, are to be carried out according to the atlas of flexible waterproof casing production, special can also be customized according to customer's demand, the length is to produce according to customer's site construction wall thickness, standard wall thickness is 300 mm, there are some drawings on by the size of the pipe diameter is also some flexible waterproof casing diameter D2, so you need to check the waterproof casing atlas norm to determine, and special design of waterproof casing can also to drawings for processing production.
A and B type waterproof casing how to choose, A type of flexible waterproof casing at one end of the filling sealing materials and sealing paste, B type flexible waterproof casing at both ends to filling sealing materials and sealing paste, so compared with B type flexible waterproof casing has A better seal waterproof performance. Selects the type I and type II should be strictly abided by during the selection rule, the sealing requirements of general use type I, hermetically sealed to choose type II. Type I waterproof casing seal ring is two annular rubber sealing ring, through mutual extrusion pressure plate and baffle ring deformation of seal ring to achieve sealing effect. Type II waterproof casing seal ring is composed of single trapezoidal annular rubber sealing ring, the working principle of the latter is like a plug, use on the civil engineering from the technical point of view in terms of the latter's sealing performance and service life of sealing performance is better than the former.
Pay special attention to when the temperature is beyond the scope to use 20 degrees (- - + 80 degrees c) sealing material and the product material will make corresponding adjustment. Size as far as possible is according to the national standard drawings. Should be noted, we will follow the plot, to adapt to the design, production, wing ring, please put forward the use of specific size can be processed according to the actual requirement. Flexible waterproof casing is installed on the pipeline as far as possible in accordance with the rules, such as the actual situation does not allow, please put the actual detailed instructions on the use of the environment, there is a requirement for corrosion resistance, must according to decay with relative material requirements.
Whether it's with A flexible waterproof casing or type B flexible waterproof casing, is to protect the building wall pipe have A much better, not only convenient for later pipeline maintenance, more important is to solve the protective wall pipes thoroughly solve the water leakage problem.
