Waterproof Casing Selection Depends on the Characteristics of the Circulation Medium

Waterproof casing is divided into the rigid waterproof and flexible waterproof casing pipe, rigid waterproofing casing is generally installed in the pipeline at the wall without the displacement of the vibration or the place; it is considered the vertical bearing capacity, single protective effect of the pipes. Flexible waterproof casing is generally installed in according to strict waterproof requirement of pipeline route, and can be installed in the pipe wall of a shock. So the effect of rigid waterproofing casing is its compressive strength, the effect of flexible waterproof casing is its resistance to vibration and sealing.

But the installation work of both flexible and rigid it need according to the characteristics of the medium to carry out the construction. If is ordinary water pipe flow medium, for his seal only is the most common gasket, external filling and sealing compound is also choose some of the more common waterproof performance of material. But if the circulation medium is has certain corrosion performance, will choose fluorine rubber sealing ring material, at this time because of fluorine rubber has good corrosion resistance, can effectively control media, and to be on the safe side, sealing filler will choose corresponding corrosion of raw materials, for the safe operation of pipeline and double insurance. Medium and pipe if salt solution is, that also need to be careful. Because salt solution does not directly corrosion waterproof casing, but if leaked he will react and wall body of calcium, lead to loose wall, wall's physique is likely to cause local collapse of wall.
