There are three key reasons for the blockage of expansion joint in Fujian Province

Leading to Fujian Telescopic joint There are three key reasons for the blockage. Let's take a look:


First, in some areas where villages have been relocated, the drainage pipes of many households are wider than the expansion joints of the drainage pipeline network. The residents inadvertently flush vegetable stems, large objects, dirty things, clothes and trousers into the sewer pipes, making the transmission difficulty coefficient increase.
Second, because many small restaurants do not have oil tanks, these restaurant wastes with a lot of oil stains are easy to coagulate after they rush into the sewer pipes and deposit in the sewer pipes. This kind of waste composed of oil stains, disposable chopsticks and their waste packaging bags may block the expansion joint pipe network of the drainage pipeline, and even cause intestinal obstruction of the drainage pipeline equipment.
Third, some civil type canals are connected with the municipal drainage network, and the wastes thrown by the residents in the civil type canals will enter the drainage pipeline network, causing the pipeline network of the expansion joint of the drainage pipeline blocked.
The expansion joint plays an important role in our daily life. However, in the specific operation process, we must purchase the relative goods according to our own requirements. Otherwise, it will do great harm to everyone's application.
