Why Pipe Expansion Joints is Essential for Piping Systems?

Manufacturing industries always rely on piping for carrying gases and fluids from one place to another. The piping system is designed to operate in different conditions such as the pipes are required in both low and high temperatures. However, problems do occur, and proper machinery and maintenance are essential. There are instances where manufacturers experience repeated failures at the same time multiple times even though the repairing, installation, and aligning of the pump had been appropriately done; still, there are issues with chronic vibration. When checked carefully, the pump was not emitting any vibrations, but the pump was affected by fluctuations from other equipment as it traveled along the pipes. In this situation, pipe expansion joints are the rescuer.

The expansion joints are made of tie rods, covers, and flow liners. A proper flow depends on the movement of the connected pipes. If the piping systems are not fitted with expansion joints, high stresses can occur due to thermal expansion. This causes high-pressure that results in the bending of the pipes and crack in the welds. More than a coil also referred to as corrugation used for making an expansion joint. The ridges are designed for tolerating the huge-pressure of the whole system. The assembly of the bellows is placed in a specific way so that it can flux under the thermal movement of the interlinked pipes.

Different types of expansion joints needed in piping systems

Common expansion joints and Universal expansion joints

The typical expansion joints created by the expansion bellows manufacturers are single expansion joints that are required to undergo a small amount of angular and lateral movements in the piping system. You can also use double expansion joints made of two or more bellows connected by standard connectors.

Universal expansion joints have two bellows that are fitted with tie rods and linked with a center pipe and can absorb general movements like angular, lateral, and axial in the piping system. The advantage of using such joints is they can able to absorb a massive amount of lateral offset.

Hinged expansion joints, axial expansion joints, and metallic expansion joints

Another type of pipe expansion joints is the hinged expansion joints that help in absorbing the angular rotation. The joint comprises two hinged plates linked to the end connection, and the purpose of the hinged hardware is to absorb the pressure of the joint expansion assembly.

The axial expansion joints are used to absorb the angular movement in the piping system. Two sets of rings are linked with a floating ring responsible for absorbing the pressure of the joint expansion assembly.

The metallic expansion joints can withstand enormous pressure and used in the extreme pressurized designs to make sure the bellows are safe from the outer pipe casing. If you have manufacturing machinery and want the equipment to operate all the time smoothly, it is essential to install pipe expansion joints of high quality. Before installation, you should know the type of fittings suitable for your system.
