One of the key features of our Expansion Double Sphere Joint is its outstanding corrosion resistance. Made from high-quality rubber materials, this joint is resistant to corrosion, making it an excellent choice for use in harsh environments where other materials might fail.
Our Hinged Flexible Rubber Joint is also incredibly durable and long-lasting. With a mold type that includes more than 2000 sets of different types, our joint is designed to withstand the test of time and work flawlessly for years to come.
The connection type of our Double Sphere Flexible Rubber Joint is flange, making it incredibly easy to install and maintain. With a simple and straightforward design, this joint can be quickly and easily connected to your pipeline without the need for any specialized tools or equipment.
The double sphere rubber joint consists of two rubber spheres and an intermediate nozzle connecting them. Compared with the single ball rubber joint, the double ball structure makes it have greater expansion and displacement compensation ability. The intermediate nozzle between the two spheres plays a connecting and stabilizing role, which can better adapt to the complex deformation of the pipe.
The spherical part of the double ball rubber joint is also composed of an inner rubber layer, a cord layer and an outer rubber layer. The inner rubber layer is in direct contact with the conveying medium, requiring good corrosion resistance and sealing; The cord layer is used to enhance the strength of the sphere and resist the internal pressure; The outer rubber layer mainly plays a protective role to prevent the erosion of the sphere by external factors such as ultraviolet light and chemical substances.

Because of its good comprehensive performance, the double-ball rubber joint has been widely used in the pipeline system of water supply and drainage, HVAC, chemical, petroleum, electric power and other industries. In the water supply and drainage pipeline, it can compensate the displacement of the pipeline caused by ground settlement, temperature change and other factors; In chemical and petroleum pipelines, it can adapt to the deformation of pipelines under complex working conditions, and at the same time ensure the safe transportation of media.
The double ball rubber joint can be used with a variety of pipe materials and connections. Whether it is metal pipe (such as steel pipe, cast iron pipe) or non-metal pipe (such as PVC pipe, PPR pipe), it can achieve good connection and displacement compensation. Moreover, it can be connected with the pipeline through a variety of ways such as flange connection and clamp connection, which is convenient for installation and maintenance.
The Double Sphere Flexible Rubber Joint is designed to absorb vibration, noise, and shock in piping systems. It consists of two spherical rubber bellows that are connected by a metal flange. The rubber bellows allow for lateral and angular movement, making it ideal for applications with misaligned pipes or thermal expansion.
