Can ductile iron pipes be made of flexible waterproof sleeves?
Flexible waterproof casing is suitable for pipeline through the wall in vibration or by strict waterproof requirements of the structures of hardware fittings, general production enterprises according to the Construction Science Research Institute developed S312, 02S404 standard atlas manufacturing. The wall of flexible waterproof casing wall, in case of non concrete should be replaced by concrete walls, and a casing must be solidified on the wall; flexible waterproof casing application widely used in construction, chemical industry, iron and steel, tap water, sewage treatment and other units.
The casing can be divided into ordinary casing to be 2-4 cm thick than the pipe to be used and fixed to the wall or plate, and the pipe passes through it. Flexible bushing - between the casing and pipe, with flexible material to seal the sealing effect. Rigid casing - that is, between the casing and pipe with rigid material sealed to achieve sealing effect. Waterproof casing - is the use of the casing of the environment is to prevent liquid leakage or leakage into place (such as the pool, septic tanks, basement, etc.) is on the outer wall of the bushing is not less than 1 times increase waterproof wing, this wall is poured in the casing as a whole, not because of swelling shrinkage factor and crack and leakage.
Usually, a bushing is used to make a pool. It is the conduit to the sink. However, the common casing is difficult to seal so that there is water leakage between the casing and the pipe and water leakage between the casing and the wall. Only the waterproof sleeve can solve the water leakage between the casing and the wall, but it can not solve the seal between the casing and the pipe, and the flexible waterproof bushing can solve two problems.
