Guide to Spring Hanger Selection and Design using Caesar II

Description

One critical component in this support system is the spring hanger, a device designed to absorb and isolate the dynamic forces that can impact a piping system.

Spring hangers are mechanical devices used to support piping systems by compensating for thermal expansion, vibration, and other dynamic forces. By providing a flexible connection between the pipe and its support structure, spring hangers help mitigate the stresses that can lead to premature wear, fatigue, and failure of the piping system. These devices are particularly crucial in industrial settings where temperature variations, machinery vibrations, and other external forces are common.

Design Considerations:

1. Load Analysis:

   • Conduct a thorough analysis of the loads acting on the piping system. Consider static loads, thermal movements, and dynamic forces such as vibrations.

   • Take into account the weight of the pipe, fluid, insulation, and any additional equipment attached to the piping system.

2. Operating Temperature Range:

   • Determine the expected temperature fluctuations in the system. This is critical in selecting spring hangers that can accommodate thermal expansion and contraction.

3. Vibration Analysis:

   • Identify potential sources of vibration and conduct a vibration analysis. Choose spring hangers with appropriate stiffness and damping characteristics to effectively isolate vibrations.

4. Corrosion Protection:

   • Consider the environmental conditions and potential exposure to corrosive elements. Select materials and coatings that resist corrosion to ensure the longevity of the spring hangers.

5. Installation Constraints:

   • Evaluate the available space for installation and any restrictions that may impact the selection of spring hangers. Consider factors such as clearance requirements and the need for specialized installation equipment.

The design and selection of spring hangers are critical steps in ensuring the reliability and longevity of piping systems. This course will provide most of the required information for the design and selection of both variable and constant spring hanger supports. A case study of spring hanger design and selection method using Caesar II software is also provided.
