Rubber joints are also known as rubber hose flexible joints, flexible rubber joints, rubber flexible joints, flexible rubber joints,
high-pressure rubber joints, rubber shock absorbers, compensators, etc
Detailed information
It is classified into three types according to the connection method: loose flange type, fixed flange type and threaded type.
According to the structure, it can be classified into five types: single sphere, double sphere, reducer, curved sphere and wind pressure coil.
It is composed of inner and outer rubber layers, fabric layers and steel wire rings to form a tubular rubber part. After vulcanization and molding,
it is loosely combined with metal flanges or parallel joints. This product can reduce vibration and noise, and compensate for thermal expansion
and contraction caused by temperature changes. It is widely used in various pipeline systems.
This product is widely used in basic projects such as chemical engineering, construction, water supply, drainage, petroleum,
light and heavy industry, refrigeration, sanitation, plumbing, fire protection, and power.
