Product Description:
Concentric reducing rubber joint, also known as concentric large
and small head rubber soft joint or rubber reducing joint, is a
specially designed pipeline connection component mainly used to
connect two pipes or equipment with different diameters. This type
of joint is made of high-quality rubber material, which has
excellent elasticity, wear resistance, aging resistance, and tear
resistance, and can adapt to various complex working environments
and medium conditions.
Structural Characteristics:
The structural design of the concentric reducer rubber joint
enables it to ensure a smooth transition of the piping system at
the joint. It usually consists of an inner rubber layer, a
reinforcing layer (e.g., cord fabric or steel wire reinforcing
layer) and an outer rubber layer. The inner rubber layer is in
direct contact with the medium and needs to have good corrosion
resistance and sealing; the reinforcing layer provides the strength
and stability of the joint; and the outer rubber layer protects the
inner structure and enhances wear resistance.
Since the two ends of the joint have different diameters, special
attention needs to be paid in the design to ensure that the
connecting surfaces of the two ends are concentric with the axis of
the pipeline, in order to avoid leakage or damage caused by
eccentricity.
Applications:
The liwei Concentric Reducing Rubber Joint is suitable for use in a
wide range of applications. It is commonly used in industrial settings, such as in chemical
plants, oil and gas refineries, and power plants. The product can be used to connect pipes of different sizes, such
as in pipeline systems that require a reduction in diameter. The product is also commonly used in plumbing and heating systems,
and can be used to connect different types of pipes, such as copper
and steel.
