Applications

The double ball rubber flexible joint perfectly makes up for the problem that the single ball rubber flexible joint cannot be installed due to its length. At the same time, its structural material is rubber impregnated nylon cord fabric, and its internal and external surfaces are made of high-strength aging resistant polar rubber materials. Because the expansion joints of many pipes are different in design, the characteristics of KXT single ball rubber soft joint can not meet the requirements of pipe expansion joints in the use of single ball rubber soft joint. Therefore, double ball rubber soft joint is required to make up for the shortcomings of single ball acid and alkali resistant rubber soft joint in terms of installation length and expansion.
