DN250 waterproof casing flexible waterproof casing rigid waterproof casing

Yucheng flexible waterproof casing is a hardware pipe fitting suitable for buildings where the pipe passes through the wall and is subject to vibration or has strict waterproofing requirements. The general production company manufactures it according to the standard atlas developed and designed by the Institute of Building Science. If the wall where the flexible waterproof casing penetrates is non-concrete, a concrete wall should be used instead, and the casing must be solidified in the wall at one time. Flexible waterproof casing is widely used in construction, chemical industry, steel, tap water, sewage treatment and other units. Three major principles for manufacturing flexible waterproof casings by Gongyi Yucheng Water Supply Equipment Co., Ltd.
First, when connecting flexible waterproof casings, strong counter-port heating of flexible waterproof casings plus inclined pads or multi-layer pads must not be used to eliminate the gap at the end face. Deviation, misunderstanding or disagreement, etc.
During the installation of the second flexible waterproof casing, open pipes should be closed. The connection between the pipe and the equipment should not subject the equipment to additional external force
During the installation of the third flexible waterproof casing, the hose should avoid sharp bends with an outer diameter larger than The minimum bending radius of the hose is more than twice the outer diameter. The minimum bending radius of the hose is less than or equal to the pipe diameter. The hose must not change or deform when stationary or moving randomly. Its length must not only meet the bending radius and stroke, but also have a left and right margin. After installation, the hose must not have friction with each other and other objects. It must be close to the heat source. Insulation method.
