How to deal with the telescope leakage?

Generally, the phenomenon of leakage of the expander is mainly because the sealing part of the expander product, that is, the rubber ring, manufacturers normally use the expander for installation, the corrosion resistance of this rubber ring, aging performance are better, in the normal process of pipeline compensation operation, the general service life of at least 5 years, but some users in the purchase of products, normal installation and use Less than half a year, the above problem, in general, is some unscrupulous manufacturers, the use of recycled rubber as a rubber seal manufacturing materials, recycled rubber tension wear resistance performance in all aspects is not as good as natural rubber, so in the application will cause a leak caused by the rubber sealing structure, such a situation, you can replace the special rubber seal material, replacement can Meet the needs of the user's use. It can be seen that the purchase of products is not only to listen to the price, greedy for cheap, good quality is the hard truth. When used in the pipeline, due to the different transportation materials, the pipeline may produce some dirt, or likely to corrode the inner cavity and surface of the pipeline. The characteristics of the corroded expander will be reduced and the safety of the pipeline will have some safety risks, so its maintenance seems to be very important. It is widely used in the software of piping system such as power supply, drainage pipe and cooling circulating water. After placing the bolts and expanders, the measuring personnel will adjust the bolts and expanders again. After calibrating and checking the standard provisions, the underside of the bolts will be welded firmly to the fixing frame. In addition, additional welded scissor brackets should be added horizontally and vertically to the bolted fixing frame. The expander shall be made according to the buried part and length of the ground bolt before the concrete is poured for the column foundation concrete.
