Single-ball elastic expansion joints are also called pipeline expansion joints, rubber joints, expansion shafts in the pipe, rubber joints, pipe joints, rubber joints, etc. It has the characteristics of high pressure resistance, good elastic metal, large displacement, enhanced pipeline, adsorption, good rubber cloth ball effect, and convenient installation.
Product function: Unique design, simple structure, good sealing performance, thermal expansion and cold contraction joints completely solve the pipeline problems caused by expansion and cold, as well as mechanical and pipeline vibration.
The expansion range of the telescopic tube is very wide, and its elasticity and the elasticity of the pipe joint provide the pressure within the range . Sections protect piping systems by avoiding them.
Impressive designation and featured materials for pipe expansion joints
Use long, run high.
Single ball rubber joints are used in industrial environments and in plant and process engineering, as well as in mechanical engineering, building services engineering, environmental engineering and hydraulics.
Pipe rubber joints are available in diameters ranging from 1" to 120" and can be made of any elastomeric material
Can meet various motion requirements, non-standard design can be manufactured as required
The elastic expansion joint has high working pressure, burst and good elasticity.
