Dual-ball Flexible Rubber Joint

The double ball Rubber Soft Joint perfectly makes up for the problem that the single ball rubber soft joint cannot be installed due to its length. At the same time, its structural material is made of dipped nylon cord fabric, and the inside and outside are made of high-strength anti-aging polar rubber material.
It prevents the natural shrinkage of double-ball rubber soft joint products and reduces aging cracks in long-term use.
Because there are many differences in the expansion joints of the pipelines left in the design of the pipelines, the characteristics of the single sphere rubber soft joints in the use of the single sphere rubber soft joints can no longer meet the needs of the pipeline expansion joints, so it is necessary to use double Ball rubber soft joint to make up for the lack of single ball acid and alkali resistant rubber soft joint in terms of installation length and expansion.

With unique design, novel structure and good sealing performance, the double sphere rubber soft joint solves the pipe burst and damage to the pipe connection equipment caused by thermal expansion and cold contraction, and effectively improves the service life of the pipeline and the protection of the equipment. Compared with the single sphere, the double sphere has a larger compensation amount. It is widely used in various pipeline systems. Connections with pumps and Valves, fire-fighting equipment, pipelines with large vibrations, and pipelines with frequent changes in cold and heat. Mainly used for lifting and conveying raw water and sewage, feed water and cooling circulating water in thermal power plants, metallurgical industry, condensate water, pipeline transportation of chemical substances in chemical industry, cooling, dilution in petrochemical industry and other industries. Flexible connection. Because rubber has high wear resistance, it is also suitable for low-temperature transportation of granular and powdery and vapor in all industries.
