In the selection of waterproof casing, should be based on the construction environment of the casing and construction design standards, choose the waterproof casing produced by regular manufacturers, choose the appropriate model, size of the product, the pipeline circulation medium corrosive, stainless steel flexible waterproof casing can be selected, different caliber waterproof casing thickness, and then the welding quality. Waterproof casing is generally double-sided welding, the weld should be smooth, no porosity and false welding.
Building exterior wall leakage is the pipeline inside the wall to the wall leakage, if the leakage is serious, it will cause wall cracking, seriously affecting the quality of the use of the building. Therefore, during construction, pipes should take into account the leakage situation and be prepared to prevent it before it happens.
Because there are more types of waterproof casing, the common ones are flexible waterproof casing and rigid waterproof casing, rigid waterproof casing is produced by seamless steel pipe and wing ring welding, simple construction, with enhanced pressure resistance, applied in the general pipeline over the wall, flexible waterproof casing is composed of seamless steel pipe body, wing ring, clutch pressure plate, sealing ring and other parts, with better moisture resistance and tightness, applied in areas with waterproof provisions and areas subject to vibration, such as cisterns, etc. Other specifications of waterproof casing are also available: rigid composition waterproof casing, hot-dip galvanized electrical equipment waterproof casing, natural ventilation waterproof casing, protective airtight casing, etc. The actual application regulations are selected
