What are the advantages of extended waterproof casing?

Waterproof casing is a hardware pipe fitting for structures subject to vibration or tight waterproofing requirements where the pipe passes through the wall, and is generally manufactured by manufacturers according to the S312 and 02S404 standard drawings developed and designed by the Institute of Building Science. Extended waterproof casing has the same structure and shape as ordinary waterproof casing, including rigid waterproof casing and flexible waterproof casing. The difference is that the length of the steel pipe carrying the wing ring is lengthened according to the thickness of the structural wall. In areas with high regulations, such as reservoirs, human defense walls, etc., more flexible waterproof casing is chosen; rigid waterproof casing is mainly used in areas where pipes pass through walls, such as the lower chamber of villa basements. Its effect is to maintain the pipeline, the two are mainly used in different areas.
Rigid waterproof casing and flexible waterproof casing is different, the appearance is different, flexible waterproof casing internal rubber water stop ring, such as when used in the pool wall to prevent leakage. Their installation length is different, the standard length of flexible casing is 300mm while the standard length of rigid casing is 200mm, but they have a common point is that they can be lengthened or shortened at will for construction needs.
Extended waterproof casing is mainly used to protect the pipeline from damage, to prevent the pipeline from being crushed by the load, and set up protective casing outside the pipeline, such as: large diameter concrete pipeline, large diameter steel pipe to avoid external forces acting directly on the outer wall of the pipeline, causing damage to the pipeline, and measures.
Extended waterproof casing has a wide range of applications, widely used in artificial protection, or underground engineering, and water or other tight waterproofing industry, the reason why stainless steel waterproof casing is so widely used, it is because stainless steel waterproof casing is used for waterproofing. Water, plants, human defense projects, clear water pools in sewage treatment plants, chemical plants, fertilizer plants, sulfuric acid, hydrochloric acid manufacturers.
