Are swivel hangers necessary for swing joints in pipe systems?

Understanding Swing Joints in Pipe Systems

In pipe systems, swing joints are an essential component that allows for flexibility in piping arrangements. These joints are commonly used in applications where thermal expansion or settling of the connected piping is expected. Swing joints absorb any linear or angular movement, ensuring the integrity and longevity of the entire pipe system. However, the question arises as to whether swivel hangers are necessary to facilitate the proper functioning of swing joints. Let’s explore the role of swivel hangers in pipe systems and assess their necessity.

The Purpose of Swivel Hangers

Swivel hangers, also known as pipe hangers or supports, are devices designed to suspend pipes and provide support while allowing for movement. They are crucial in overcoming the challenges posed by thermal expansion, vibration, and settling of the pipe system. Swivel hangers consist of a suspension apparatus that can rotate and move in response to any shifting or movement of the pipes, ensuring that the pipes are adequately supported while accommodating any necessary flexibility.

Advantages of Swivel Hangers

1. Mitigating Stress: One of the key benefits of swivel hangers is their ability to reduce stress on pipe systems. When pipes undergo thermal expansion or contraction, stress can develop at connection points, leading to potential damage. Swivel hanger systems act as shock absorbers, reducing the stress and preventing cracks, leaks, or ruptures in the pipes.
2. Accommodating Movement: Swivel hangers are specifically designed to allow movement in the pipe system. When pipes experience thermal expansion, they tend to elongate, which can result in misalignments or pulls. Swivel hangers absorb these expansions, rotations, and displacements, preventing damage to the pipes or adjacent structures.
3. Minimizing Vibration: In many industrial settings, vibration is a common occurrence due to heavy machinery or turbulent fluid flow. Swivel hangers play a vital role in minimizing the transmission of vibrations through the pipe system. By isolating and dampening the vibrations, swivel hangers help prevent them from negatively impacting the performance or structural integrity of the pipes.

The Role of Swivel Hangers in Swing Joints

Swing joints are designed to allow for movement in multiple directions, including linear and angular motion. These joints incorporate a flexibly connected section that compensates for any potential pipe movement. While swing joints themselves provide some level of flexibility, swivel hangers are often employed to enhance their efficiency and longevity.

1. Supporting Weight: By attaching swivel hangers to swing joints, the weight of the pipe system can be properly distributed. Swivel hangers act as suspension devices, providing support and preventing excessive stress on the swing joints.
2. Enhancing Flexibility: Swing joints alone may not be capable of providing adequate flexibility in certain applications. Swivel hangers facilitate enhanced flexibility by allowing smooth rotation and movement of the swing joints, accommodating both linear and angular displacements.
3. Ensuring Stability: Swivel hangers play a critical role in maintaining the stability of swing joints. By securely attaching to the swing joint and providing support, swivel hangers prevent any unintended movement or misalignment of the swing joint. This ensures that the swing joint functions as intended and prevents potential damage to the pipe system.

When it comes to swing joints in pipe systems, swivel hangers are indeed necessary. These devices play a vital role in supporting, accommodating movement, and minimizing stress and vibration in the system. Swivel hangers enhance the overall efficiency, flexibility, and longevity of swing joints, ensuring the proper functioning and integrity of the pipe system as a whole. Therefore, investing in swivel hangers is an essential consideration for any pipe system design or installation.
