ekspansjonskoblinger

Ekspansjonskoblinger, often referred to as expansion joints or flexible connectors, are mechanical devices designed to safely absorb the movement, vibration, and thermal expansion or contraction that occurs within piping systems. These movements can arise from a variety of factors including temperature changes, pressure fluctuations, mechanical vibrations from pumps or other equipment, and settlement of supporting structures. Without proper accommodation, these forces can lead to significant stress on the piping, connections, and connected equipment, potentially causing leaks, ruptures, and premature failure.

The primary function of an ekspansjonskobling is to act as a flexible segment within a rigid piping run. They are typically constructed from a flexible material, such as rubber, metal bellows, or braided metal, reinforced to withstand the operating pressures and temperatures of the system. Their design allows them to compress, extend, or deflect in various directions – axially, laterally, or angularly – thereby isolating the stresses.

Common types of ekspansjonskoblinger include rubber expansion joints, which are versatile and effective for absorbing vibration and movement in many applications, and metal expansion joints, which are often used in high-temperature or high-pressure environments. Braided metal expansion joints offer additional strength and durability. Proper selection and installation of ekspansjonskoblinger are crucial for the longevity and reliability of any piping system, ensuring operational safety and preventing costly damage.
