SSQ cast iron expansion device

SSQ cast iron 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.

SSQ cast iron expansion device is mainly used to ensure the safe operation of pipeline, which has the following functions: compensating the axial, transverse and angular thermal deformation of absorption pipeline; absorbing equipment vibration to reduce the impact of equipment vibration on pipeline; absorbing seismic and ground subsidence deformation on pipeline.

Detailed introduction of cast iron expansion device:  
1. This 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 three kinds of pipes in the product: cast iron (HT), galvanized (DX) and steel (SF). The working pressure is divided into pn6, PN10 and PN16.
3. Before the installation of cast iron expansion joint, loosen the pressure plate bolt, pull the product to the installation length, and then tighten it with diagonal method. Do not press deviation. If it is used overhead, the corresponding fixed support must be installed at both ends.
4. The flange connection of cast iron expansion joint adopts gb4216.3-4126.5 standard.
5. Cast iron expansion joint can be produced separately if other specifications are selected.

Application range of SSQ cast iron expansion device
Due to its good comprehensive performance, the expansion joint is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and light industry, refrigeration, sanitation, water heating, fire protection, electric power and other basic projects.
The function of SSQ cast iron expansion device is as follows
SSQ type cast iron 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.

Precautions for installation of SSQ cast iron expansion joint:
1. The model, specification and pipeline configuration of the expansion joint should be checked before installation, which must meet the design requirements.
2. For the expansion device with inner sleeve, the direction of the inner sleeve cylinder should be consistent with the medium flow direction, and the hinge rotation plane of the hinge type expansion device should be consistent with the displacement rotation plane.
3. For the expansion joints that need 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 over tolerance of pipeline installation, so as to avoid affecting the normal function of the expansion joint, reducing the service life and increasing the load of piping, equipment and supporting components.
5. During the installation, welding slag is not allowed to splash on the surface of the wave shell, and the wave shell is not allowed to suffer other mechanical damage.
6. After the piping system is installed, the Yellow auxiliary positioning components and fasteners used for installation and transportation on the expansion joint shall be removed as soon as possible, and the limiting device shall 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 blocked by external components or limit its range of motion, 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.
