Rubber expansion joints are connecting elements used in piping systems to reduce vibration, noise, and absorb displacement. Different piping systems require different specifications of rubber expansion joints.
Rubber expansion joint specifications are generally classified according to their diameter and length. Diameter refers to the outer diameter of the pipe connected by the rubber expansion joint, usually expressed in millimeters. Length refers to the amount of expansion and contraction of the rubber expansion joint, also expressed in millimeters.
The diameter and length specifications of rubber expansion joints are generally determined based on the design requirements of the piping system. Different piping systems require consideration of factors such as flow rate, pressure, medium, and temperature during design, all of which affect the specifications of the rubber expansion joints.
