Flexible Steel Waterproof Casing Function
- Sep 14, 2018 -

The casing may be divided into: common casing - two to four centimeters larger than the pipe to be used, fixed in the wall or plate, through which the pipe passes. Flexible casing -- it is to seal between the casing and the pipe with flexible material. Steel sleeve - that is, between the casing and the pipe with the steel material seal to achieve sealing effect. Water-proof sleeve -- where the casing is used to prevent liquid leakage or leakage (such as water tank, septic tank, basement, etc.), is a water-proof wing with no less than one turn added to the outer wall of the casing. In this way, when the casing is poured into the wall, it becomes a whole and will not leak due to the expansion and contraction factor.
