Classification of threaded rubber joint:
1.According to the use of performance is divided into general, special, heat-resistant three categories.
2.According to the structural form is divided into a single sphere, double sphere, three spheres, elbow sphere, wind pressure coil body. Each form can be divided into concentric diameter, concentric diameter, eccentric diameter three categories.
3.Divided into: concentric diameter, concentric diameter, eccentric diameter.
4.According to the product and the pipeline connection form may divide into the flange connection, the thread connection and the
clamp connection, the thread pipe flange connection and so on.

Screw thread connection, also known as screw connection, it is through the internal and external screw pipe and pipe, pipe and valve connected. Commonly used pipe connection: Screw connection, welding and flange connection. |
According to different media used by the rubber material is different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, epdm, chloroprene rubber, silicone rubber, fluorine rubber and so on. |
This product can reduce vibration and noise, and can be caused by temperature changes in the expansion and contraction of the compensation role, widely used in a variety of pipeline systems. |
