RS type flexible sleeve type expansion device is also called sleeve type expansion device, thermal pipeline expansion device, pipeline expansion device, etc. RS type flexible sleeve type expansion device has the performance of long life, convenience and durability, which solves the problem of no deflection angle of the original sleeve type expansion device. The product has a large deflection angle of 5.85 degrees. Based on the common loose sleeve expansion joint, RS type flexible sleeve expansion joint can have a certain amount of angular displacement by adjusting the shape of the body, so as to better adapt to the actual use environment of the pipeline.
1. RS type flexible sleeve type expansion device solves the problem that the original sleeve type expansion device does not produce deflection angle. The product has a large deflection angle up to 5.85 degrees;
2. The length values in the table are the values without deflection angle;
3. The expansion device is sealed by rubber ring, and the expansion device itself can not bear the axial tension, so it is generally installed on the straight pipe. If it is installed close to the elbow or T-shaped pipe, the pipe buttress shall be set to prevent the expansion joint from pulling off and water leakage;
4. The single disc short pipe in the expansion device can be replaced by cast iron straight pipe with outer diameter;
5. 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.
6. The inner pipe of this product is divided into cast iron (HT), galvanized (DX) and steel (SF). The flange connection size adopts GB / t9115.1-2000 standard; P > 0.05

Product advantages

RS type flexible sleeve type expansion device solves the problem that the original sleeve type expansion device does not produce deflection angle. This product has a large deflection angle up to 5.85 degrees. Compared with the traditional expansion joint, it has better sealing and anti pulling off performance. The product is suitable for conveying seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, oil, lubricating oil, product oil, air, gas, steam with temperature not higher than 250 ℃ and particle powder. The expansion device is sealed by rubber ring. The expansion device itself can not bear the axial tension. It is generally installed on the straight pipe. If it is installed close to the elbow or T-pipe, the pipe buttress shall be set to avoid water leakage caused by pulling off the expansion device. The sealing performance is good and it is not easy to leak.

Product features

Installation precautions of RS type flexible sleeve type expansion joint:
1. Before installation, the model, specification and pipeline configuration of RS type flexible sleeve type expansion device should be checked, and the design requirements must be met.
2. 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.
3. All moving elements of sleeve type expansion device shall not be stuck or restricted by external components, and normal operation of each moving part shall be ensured.
4. 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 above is a detailed introduction to RS type flexible sleeve type expansion device. Shanghai Luoying adopts advanced technology and first-class technical personnel in strict accordance with the product quality system standard. Every product is inspected and tested strictly, occupying the market with quality and winning customers with integrity.

classic case

The sleeve type expansion device has brought guarantee for the development of pipeline industry in Jiangsu Province

The Yangtze River Delta urban agglomeration, which is composed of Jiangsu, Shanghai, Zhejiang and Anhui, has become one of the six world-class urban agglomerations in the world. Jiangsu's per capita GDP, comprehensive competitiveness, regional development and people's livelihood index (DLI) all rank among the provinces in China, becoming a province with high comprehensive development level in China, and has stepped into the middle and upper developed level. Jiangsu Province, especially its pipeline industry, is developing rapidly.
The sleeve type expansion device is composed of body pipe, expansion pipe, pressure flange and sealing ring. Now, the sleeve type expansion device is more suitable for water supply and drainage engineering, which provides convenience for the installation and removal of water meters and valves in urban water tower, pump room, etc. the sleeve type expansion device also plays a good role in filling the expansion and contraction problems caused by the temperature difference of long distance pipeline.
Since the sleeve type expansion device has such a good use, the following points should be paid attention to when installing the sleeve type expansion device:
1. The installation length is very good between large and small length, so that it can be adjusted according to the actual situation or problems. In general, one half of the telescopic amount of the telescopic sleeve is selected as the standard.
2. When installing the sleeve type expansion device, it is necessary to loosen the pressure plate bolt, adjust the installation length, and then tighten the bolt diagonally. Do not press it off to prevent leakage.
3. The expansion must be installed at the back of the check valve.
4. The expansion device is like overhead use, both ends must be installed with corresponding fixed support, its own will not bear the axial tension, when necessary, it can be added with anti pulling device.
The sleeve type expansion device produced by Luoying pipeline has good displacement compensation function, long service life and large expansion and contraction capacity. Because of the good comprehensive performance of the expansion joint, it can be widely used in chemical engineering, construction, water supply, drainage, oil, light and light industry, refrigeration, sanitation, water heating, fire protection, electric power and other basic projects.
