The uses of double-sphere rubber joints.

The double-sphere Rubber Expansion Joint employs a multi-wave design, which increases its length and enhances its compensation capacity. It is specifically designed for use with cold water, hot water, compressed air, natural gas, etc. With its innovative design, novel structure, and excellent sealing performance, it effectively addresses issues such as pipeline bursting and damage to pipeline-connected equipment caused by thermal expansion and contraction, thereby significantly extending the service life of pipelines and protecting the connected equipment. Compared to the single-sphere rubber expansion joint, the double-sphere version offers greater compensation capacity.

This Double Ball Rubber Expansion Joint is manufactured by our company using a new air-blow molding process. It consists of a composite sphere made up of an inner rubber layer, a reinforcing layer, a middle rubber layer, and an outer rubber layer, along with a loose-sleeve forged low-carbon steel Flange. The product boasts characteristics such as high pressure resistance, good elasticity, large displacement capacity, effective vibration absorption and noise reduction, and convenient installation.

It can be widely applied in pipeline systems for water supply and drainage, HVAC (Heating, Ventilation, and Air Conditioning), fire protection, compressors, papermaking, pharmaceuticals, ships, water pumps, fans, and more.
