Introduction: The key of steel flexible casing is composed of flange waterproof sleeve, sealing ring, flange pressure plate, wing ring, bolt and nut, with complicated structure. Then the steel flexible casing pipe is applied in the wall of the building without bearing the pipe vibration and telescopic deformation, and the wall can be used generally

The key of steel flexible casing is flange Waterproof casing Flange, nut, flange ring, etc. Then the upper steel flexible casing is applied in the wall of the building without bearing pipe vibration and telescopic deformation, and the general available wall thickness is 200 mm. The key of steel flexible casing can be used in the wall of buildings with strict waterproof regulations, bearing pipeline vibration and telescopic deformation according to earthquake disaster regulations, and the general available wall thickness is 300 mm.
Classification; steel rigid waterproof casing; a, B type. Type A is suitable for seamless steel pipe and type B is suitable for pig iron and ductile iron pipe. Steel flexible casing is divided into: A, B type. A is used in the internal and external walls of the building, and type B is used in the wall of the building. The steel flexible sleeve is welded with a water stop wing ring on the outer edge of the seamless steel pipe. The steel flexible sleeve is welded with three flange rings on the outer edge of the seamless steel pipe. There are four turnbuckles on one side, a baffle plate is welded inside, and an intersection ring is added. There is a flange plate on the outside, and four stud bolts are added. A seamless steel pipe is welded on the top of the head. After the seamless steel pipe is installed, the flange is pressed and the screw is tightened The larger the rubber ring, the less water seepage. It is generally used in areas with high waterproof requirements, such as the drainage outlet of the reservoir and the pipeline connecting the centrifugal pump through the wall.
Pay attention to the following five points in the installation of steel flexible casing:
1. Pay attention to whether the upstream surface is corrosive chemicals. Corrosive chemicals do great harm to the installation of steel flexible casing. The harm caused by erosion should be considered. Therefore, for corrosive chemicals, steel flexible casing should be paid more attention.
2. Steel flexible casing must be embedded into the concrete in advance, and must ensure the level to avoid deflection. When used in the reservoir, pay attention to the position of the water facing and out of the water. It must not be avoided.
3. During the pipeline connection, in order to ensure sufficient sealing effect, in addition to the application of sealing gasket sealing, it is also necessary to prepare asphalt batting or polyethylene insulation foam board for filling in advance, so as to avoid water leakage.
4. In the case of selecting sealing gasket, it is necessary to select the sealing gasket with large total area. It is not necessary to apply annular sealing gasket, but ladder or other type of gasket can be applied. However, it is necessary to ensure that the sealing gasket is sufficient with the surface of pipeline.
5. If the wall of steel flexible casing passing through the wall is not concrete, its position must be adjusted to the concrete wall, so as to ensure the reliability of the steel flexible casing, which is very important for the installation and sealing of steel flexible casing.
For the installation of steel flexible casing, because it will contact with water immediately, the actual sealing effect becomes a difficult problem to be considered. Generally, if the actual sealing effect is ensured, the installation skills of steel flexible casing are grasped. Steel flexible casing is generally used in the basement of villa and other pipeline should pass through the pipeline. The results show that the groove width of steel flexible casing is only large, and the error value is less than or equal to 0.30mm, and the management deviation displacement of the movement track groove is less than or equal to 0.50mm. If the repair of H7 / H7 is allowed, it is not allowed to cooperate with each other after the loose repair of H7 steel sleeve. The thickness of the steel flexible casing at the moving track shall not be less than 19.00mm. After repairing, the inner hole of the steel flexible casing should maintain the roundness of the curve and the relative specification. After installation of the outer plate, inner plate and peach shaped plate of the steel flexible casing, the flatness dimensional tolerance within the range of 100 mm × 100 mm on the same plan shall be ≤ 0.05. After installation, the plan of the steel flexible casing shall be vertical to the base plane of the base plate. The height width ratio of 1000mm shall be measured accurately, and the flatness dimension tolerance shall be ≤ 2.00mm. The front plan of the steel flexible casing and the axis of the traction belt shall be vertical. The height width ratio of 1000mm shall be measured accurately, and the flatness dimension tolerance value shall be ≤ 2.00rnm. The dimension tolerance of parallelism between the motion track axis of steel flexible casing and the axis of traction belt is ≤ 4.00mm.
As an indispensable pipe material in engineering construction, steel flexible casing pipe is paid more and more attention, 02s404 waterproof casing Therefore, the steel flexible casing must have the specifications of the above performance parameters. Steel flexible casing is generally over the wall by vibration or strict waterproof provisions of the building. After a part of the steel flexible casing is manufactured, its surface shall be painted with one coat of topcoat (the top coat includes camphor Dan or cold primer oil). The surface corrosion protection of steel flexible casing is decided by design conception.
