Rigid Casing / Flexible Casing / Containment Casing Characteristics

Rigid Casing / Flexible Casing / Containment Casing Characteristics
Waterproof casing is a pipe that passes through railroads, highways, streets and other places. Its main purpose is to prevent the pipe from being crushed. It is installed on the outside of the pipe to provide protection. As there are many types of waterproof casing, including rigid waterproof casing, flexible waterproof casing, ventilating casing, sealing protection casing on both sides, rigid combination casing, etc., it is generally necessary to choose different types according to different use locations in order to give full play to the performance of the product.
1 . Rigid casing
Rigid waterproof casing is steel pipe outer wing ring (steel plate ring on the steel pipe), installed in the wall (mostly concrete walls), for general pipeline through the wall, conducive to wall waterproofing, flexible waterproof casing outside the outer wing ring, internal file ring, etc., flange inner wire, there are sets of sales, but also can be processed by themselves, for shock-absorbing pipe casing, such as the pipeline connected to the pump through the wall.
2 . Flexible casing
Flexible waterproof casing is suitable for pipelines through the wall vibration or waterproofing requirements of the structure of the hardware fittings. General production companies are made according to the S312, 02S404 standard atlas developed and designed by the Institute of Building Science. Flexible waterproof casing through the wall, non-concrete should be changed to concrete wall, casing shall be cured in the wall at one time; flexible waterproof casing and rigid waterproof casing are used for hardware fittings through the wall of the building with strict requirements of vibration or waterproofing, commonly used in construction, chemical industry, steel, water, sewage treatment and other units.
3 . Closed casing characteristics
The closed casing is mainly used for building human defense wall pipeline through the wall, to protect the pipeline to effectively prevent the damage caused by external shock waves and pollution air to the air defense basement, and at the same time play a protective and airtight role. The construction of manproof closed casing and rigid waterproof casing is similar, except that there is a wing ring outside the rigid waterproof casing and a baffle plate to prevent shock waves, which is directly welded to the wing ring and pipe. If the man-proof closed casing is set between two man-proof areas, both sides of the man-proof closed casing must be set with a wing ring and a baffle plate to prevent shock waves.
For the performance of the casing, can be summarized as follows.
Waterproof casing process characteristics, save material light, suitable for transport and construction. Tube bending capacity range is relatively wide, can be bent, can avoid these obstacles, and therefore adapt to the different terrain of the enterprise. The use of unsuccessful, thus enhancing the shape of the ring stiffness tube, and effectively assume the external load, then the voltage capacity is good. Waterproof casing tensile strength, high tensile strength, and long tube, preferably buried in the overall performance, able to withstand earthquakes and ground settlement. Has a good corrosion resistance to most students chemical reaction medium, no electrochemical corrosion.
