    Product description

    The flexible single-ball rubber joint is a kind of rubber connector, which is composed of an inner rubber layer, a rubber sphere reinforced by a nylon cord fabric, an outer rubber layer and a loose metal flange. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, and electric power.


    Features

    1. Rubber joints can greatly reduce the vibration and noise of the piping system, and can fundamentally solve the problems of interface displacement, axial expansion and contraction, and misalignment of various pipelines.

    2. According to different materials, rubber joints can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, oil resistance, heat resistance, etc., to adapt to a variety of media and environments.

    3. The rubber joint material is polar rubber, with good sealing performance, light weight, convenient installation and maintenance, and long service life, but avoid contact with sharp metal instruments to avoid puncturing the sphere.

    4. If the rubber joint is used overhead, it can be equipped with an elastic bracket, and the bolts should be tightened diagonally during installation.

    5. If the pressure of the rubber joint pipeline is too high, use limit bolts to connect the flanges at both ends.
