expansion joint typicle pattern
Expansion Joints are widely used to allow movement in piping systems while containing pressure and medium running through it. Differential settlement, thermal growth, vibration or pressure pulsation can cause movement in piping system. When flexibility for this movement can not be designed into the piping system itself, expansions joints are the ideal solutions.
Type of movement
Axial movement
Angular movement
Lateral movement
Torsional movement expansion joint
