How LATERAL EXPANSION JOINTS with welding ends absorb movements

This animation shows how movements are absorbed in an Tied Lateral Expansion Joint. Lateral expansion joints are used to absorb lateral deflection. Lateral expansion joints can move in all lateral directions simultaneously for absorbing expansion from two pipe sections in different directions. The lateral expansion joint is normally equipped with fixtures such as external tie rods, which allow the unit to absorb movements in all lateral directions but also to absorb the pressure thrust (incl. full vacuum).
