Waterproof casing and wear casing wall, wall tube.Flexible waterproof casing generally applicable for pipe through the wall of the vibration or tight waterproof demand structures, casing parts processing is completed, in its outer wall all brush priming again (primer ZhangDan or cold priming oil).Waterproof casing is divided into the rigid waterproof and flexible waterproof casing pipe.Place is not the same, they are used mainly in flexible waterproof casing mainly USES in the wall of civil air defense, demanding places, such as cistern rigid waterproofing casing pipe should be such as to pipe in the basement is commonly used in position.


Flexible waterproof casing are applicable for pipe through the wall of the structure with vibration or have strict waterproof requirements of hardware fitting, general manufacturing enterprise is developed according to the construction science research institute design S312, 02 s404 standard atlas.Flexible waterproof casing wall in the wall, in case of the concrete should be switched to concrete walls, casing must be a solidified within the wall;Flexible waterproof casing is widely used in construction, chemical, steel, water, sewage treatment etc.


Rigid waterproofing casing is a steel tube with wing ring (made of steel ring set on the steel pipe), installed in the wall (mostly concrete wall), used for general pipeline wall, wall waterproof, and flexible waterproof casing in addition to the outer ring, internal gear ring, such as the flanges silk, has a complete set of sell, also can own processing, used to have a shock to line, such as pump and connecting pipe wall.


Flexible waterproof casing or rigid waterproofing casing are used for pipeline by vibration or tight waterproof requirements through the walls of the building hardware accessories, often used in construction, chemical, steel, water, sewage treatment and other units.


The rigid waterproof and flexible waterproof casing pipe
