SS3 sleeve type socket expansion joint

Expansion joint is also called expansion joint, expansion joint, compensator and expansion joint. The expansion device can be axially retracted within a certain range, and can also overcome the offset caused by different axial joints of the pipeline in a certain angle. It can greatly facilitate the installation and disassembly of the valve pipeline. It can freely expand and expand in the allowable expansion amount of the pipeline. Once the maximum expansion amount is exceeded, it will play a limit to ensure the safe operation of the pipeline. In order to ensure the safe operation of the pipeline, it has the following functions: compensating the axial, transverse and angular thermal deformation of the absorption pipeline; absorbing the equipment vibration to reduce the impact of equipment vibration on the pipeline; absorbing the deformation of the pipeline caused by earthquake and ground subsidence.

Expansion joint is also called expansion joint, expansion joint, compensator and expansion joint. The expansion device can be axially retracted within a certain range, and can also overcome the offset caused by different axial joints of the pipeline in a certain angle. It can greatly facilitate the installation and disassembly of the valve pipeline. It can freely expand and expand in the allowable expansion amount of the pipeline.

1. The product provides great convenience for the installation and replacement of various water supply and drainage pipelines, water towers, pumps, water meters and valves, and plays a good role in regulating the expansion and contraction of long-distance pipelines due to temperature difference.
2. There are two types of pipes for the product: metal type and rubber type (for example, gsq-j (metal) and gsq-x (rubber)) for Zhonglin water supply company, and the metal types are divided into cast iron, galvanized steel and steel. The working pressure is divided into pn6, PN10 and PN16.
3. Before installation, loosen the pressure plate bolt, pull the product to the installation length, and then tighten it with diagonal method. Do not press off. If it is used overhead, the corresponding fixed support must be installed at both ends.
4. The flange connection adopts gb4216.3-4126.5 standard.
5. If other specifications are selected, it can be customized.

Precautions for installation of SS3 telescopic sleeve:
1. The model, specification and pipeline configuration of the expansion device should be checked before installation, which must meet the design requirements.
2. Pay attention to the direction of rotation of the inner hinge sleeve of the cylinder with the same direction as that of the inner plane of the telescopic sleeve.
3. For the expansion joint that needs to be "cold tightened", the auxiliary components for pre deformation should be removed after the pipeline installation.
4. It is strictly forbidden to use the method of expansion joint deformation to adjust the installation out of tolerance of the pipeline, so as to avoid affecting the normal function of the expansion device, reducing the service life and increasing the load of the piping system, equipment and supporting components.
5. During installation, welding slag is not allowed to splash on the surface of the wave shell and other mechanical damage is not allowed.
6. After the piping system is installed, the Yellow auxiliary positioning components and fasteners used for installation and transportation on the wave expansion device should be removed as soon as possible, and the limiting device should be adjusted to the specified position according to the design requirements, so that the pipeline system has sufficient compensation capacity under environmental conditions.
7. All moving elements of the expansion device shall not be stuck or restricted by external components, and the normal operation of each moving part shall be ensured.
8. During the water pressure test, the secondary fixed pipe support at the end of the pipeline with expansion device shall be reinforced to prevent the pipeline from moving or rotating. For the expansion device and its connecting pipeline used in gas medium, it is necessary to add temporary support when filling water. The content of 96 chloride ion in the cleaning solution for water pressure test shall not exceed 25ppm.
