Summary :In terms of installation, the expansion joints can be adjusted according to the actual need. However, in terms of the working process, this product is capable of transforming the axial thrust to the entire piping system. The main material of the expansion joints include the QT-400, Q235A, HT20, 304L,316L, etc.. The expansion joints can be divided into seven types, and each type is different in its own installation. The use of expansion joints serve as an protective measure due to the difference between the temperatures.

The expansion joints is an equipment that is capable of compensating the pressure in the piping system. Moreover, the expansion joints also can be applied in wide ranges, including the decoration, installation, and industries. In the previous articles, the author has introduced a lot about the types, functions as well as the installation of expansion joints. In this paper, the author would like to make a brief introduction to the working principle of expansion joints.

The working principle of expansion joints can be described as following:

The expansion joints boast the large expansion and contraction, high temperature and strong pressure area. In terms of the foundation concrete pouring and pre-buried pipelines in the building water supply and drainage projects, these engineering expansion joints are settled by the building foundations, equipment resonance, and geological changes. In the process of pipeline medium change, the location of the pipelines begins to stressed, deformed, twisted and damaged. Besides, the embedded pipelines even bring the great inconvenience to the construction unit. In order to overcome these difficulties and ensure the secure operation of the pipelines, the expansion joints can be applied. This product is capable of extending in an axial direction within a certain range, so as to overcome the various angular displacements, different hearts, expansion and contraction of the pipeline. In this way, the pipelines can freely extend within the expansion joints. If exceeds the maximize amount of expansion, the expansion joints are capable of playing a significant role in limitation.

The double flange loose limit extension joint is a kind of expansion joints. The double flange loose limit extension joint is a loose sleeve limit expander developed on the basis of the flange type expander. Compared with the general expansion joints, the double flange loose limit extension joint boats large amount of compensation. When the compensation amount exceeds to the allowable range, the limit device will act to limit the sleeve portion of expansion joints above the body portion. It will not continue to compensate for the displacement, thus preventing the casing from pulling out of the body.

The above mentioned text is the working principle of expansion joints. The expansion joints play a significant role in the pipeline system, and it serves as a protective measure due to the greatly temperature difference of the connecting bellows. The expansion joints serve as a new product connecting such equipment as pumps, valves, and pipes with the pipelines. They are connected by full bolts, making them integral as well as having a certain amount of displacement for easy installation. The expansion joints are capable of adjustment in accordance with installation size, which can not only improve the working efficiency, but also bring the protective function to the pipeline equipment including the pumps and valves.
