SSQ cast iron expansion joint introduction：

The innovative SSQ cast iron expansion joint is composed of a loose sleeve and a flange limiting short pipe combination. The SSQ cast iron expansion joint can prevent leakage and damage to the compensation joint caused by excessive displacement of the pipeline. During use, it is mainly used to absorb axial displacement within the allowable displacement range and withstand axial pressure thrust for pipeline loose sleeve connection. The internal pipes of SSQ cast iron expansion joints are divided into three types: cast iron (HT), galvanized (DX), and steel (SF). There are three types of working pressure: PN6, PN10, and PN16.

SSQ cast iron expansion joint advantage：

Cast iron expansion joints are suitable for connecting both sides with flanges. When installing cast iron expansion joints, adjust the length of the connection between the two ends of the product and the flange. Tighten the gland bolts diagonally and evenly, and then adjust the limit nuts. This way, the cast iron expansion joint can allow the pipeline to freely expand and lock the expansion joint within the range of expansion joint, ensuring the operation of the pipeline.

The innovative cast iron expansion joint has a high cost-effectiveness and superior comprehensive performance, which can be widely used in basic engineering such as chemical engineering, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, electricity, etc.

Product Features：

1. Before installation, the model, specifications, and pipeline configuration of the expansion joint should be checked to ensure that it meets the design requirements.

2. For telescopic devices with inner sleeves, attention should be paid to ensuring that the direction of the inner sleeve is consistent with the flow direction of the medium. The hinge rotation plane of the hinge type telescopic device should be consistent with the displacement rotation plane.

3. The expansion joint that requires "cold tightening" and the auxiliary components used for pre deformation should be removed after the pipeline installation is completed.

4. It is strictly prohibited to use the method of deformation of the expansion joint to adjust the installation deviation of the pipeline, in order to avoid affecting the normal function of the expansion joint, reducing its service life, and increasing the load on the pipeline, equipment, and supporting components.

5. During the installation process, welding slag is not allowed to splash onto the surface of the wave shell, and other mechanical damage to the wave shell is not allowed.

6. After the installation of the piping system, the yellow auxiliary positioning components and fasteners used for installation and transportation on the expansion joint should be removed as soon as possible, and the limit device should be adjusted to the specified position according to the design requirements, so that the piping system has sufficient compensation capacity under environmental conditions.

7. All moving components of the telescopic 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 frame at the end of the pipeline equipped with an expansion joint should be reinforced to prevent the pipeline from moving or rotating. For expansion joints and their connecting pipelines used for gas media, attention should be paid to whether temporary supports need to be added during water filling. The 96 chloride ion content of the water cleaning solution for hydraulic testing shall not exceed 25PPM.

SSQ cast iron expansion joint Application field：

SSQ cast iron expansion joint is a new product that connects pumps, valves, pipelines and other equipment to pipelines. It is connected by full bolts to form a whole and has a certain displacement, making it easy to install. Can withstand the axial pressure of the pipeline. This way, adjustments can be made according to the on-site installation dimensions during installation and maintenance. During work, it not only improves work efficiency, but also provides certain protection for pipeline equipment such as pumps and valves. This product is suitable for conveying media such as seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil, air, gas, steam and particulate powder with a temperature not exceeding 250 degrees Celsius.
