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 international good urban agglomerations. Jiangsu's per capita GDP, comprehensive competitiveness, regional development and people's livelihood index (DLI) all rank well among all provinces in China. Jiangsu has become a province with high comprehensive development level and has entered the level of middle and upper developed countries. 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 better between large and small length, which 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.
