Waterproof casing pipe：

waterproof casing pipe is also called wall casing, wall pipe. Flexible waterproof casing pipe is generally suitable for structures with vibration or strict waterproof requirements where the pipe passes through the wall. After the casing is partially processed, primer is brushed on the outer wall (primer includes camphor or cold base oil). Change for a better future, Reminder of product knowledge points for serving the Usulutan aviation industry: waterproof casing pipe is divided into rigid waterproof casing pipe and flexible waterproof casing pipe.The two are mainly used in different places. Flexible waterproof casing pipe is mainly used in civil air defense wall, pool and other places with high requirements, while rigid waterproof casing pipe is generally used in the basement and other places where pipes need to pass through pipes.

Waterproof casing pipe classification：

Flexible waterproof casing pipe, rigid waterproof casing pipe, steel flexible waterproof casing pipe, rigid closed sleeve on both sides of protection, 04FS02 flexible closed sleeve, lengthened flexible waterproof casing pipe, stainless steel waterproof casing pipe, etc.

Flexible waterproof casing pipe：

When the pipeline passes through the foundation, inner wall, floor and other places, it can avoid the disturbance to the building when the pipeline (pressure pipeline, such as water supply, heating, etc.) is used. At the same time, the flexible waterproof casing pipe is convenient for the installation and maintenance of the pipeline, and the short pipe that is set, larger than the outside diameter of the installed pipeline, and the material and length meet the requirements, is installed at the crossing of the foundation, inner wall, floor and other pipelines. Your success is our top priority, Key points of product knowledge in the aviation field that Usulutan friends need to understand： Flexible waterproof casing pipe is made of welding pipe. Both ends of flexible waterproof casing pipe should be cut mechanically (such as using toothless saw, etc.), and the wall thickness requirement is not strict. "waterproof casing pipe" is a special casing set up when the pipeline passes through the basement and other buildings and structures that have waterproof requirements. Rigid waterproof casing pipe is commonly used.

Waterproof casing pipe installed：

Due to non-standard competition in the market, flexible waterproof casing pipe is currently divided into two kinds: national standard and non-standard. The national standard refers to material selection and production according to 02S404 or 02S312 standard atlas related to the Ministry of Construction, which has strict requirements on flange thickness, wing ring thickness, pipe diameter and pipe wall thickness. According to the design standard size. Easy decisions come from knowledge accumulation, Zhongyuan valve fittings reminds Usulutan friends that this information is helpful: Non-standard refers to the difference between flange thickness, wing ring thickness, pipe diameter and pipe wall thickness, so as to reduce weight and cost, when the shape and general structure meet the requirements of the atlas. If Usulutan customers operation needs something that is not on the market, our team will make it, Key points of product knowledge in the aviation field that Usulutan friends need to understand： Strictly speaking, these are unqualified products. Of course, to make a slight difference in the thickness and pipe wall size can reduce the engineering cost and not affect the use of, but to some extent affect the use of performance.

The installation position of waterproof casing pipe should avoid settlement joint, expansion joint or two structures (construction) in close distance. If a non-concrete wall is encountered at the point where the casing passes through the wall, the concrete wall should be partially used. Our customers want the best, so we provide the best, Zhongyuan valve fittings reminds Usulutan friends that this information is helpful for choosing Chinese products: The pouring range should be 200 larger than the diameter of the wing ring (D5), and the casing should be fixed inside the wall at one time.
