Course content

1 section • 6 lectures • 1h 23m total length

  • Introduction12:58

    Explore spring hanger design and selection for piping systems using scissor two software, covering variable and constant hangers, components, and a practical case study.

  • Types of Spring Hangers11:33

    Learn variable and constant spring hangers, their load variation with thermal displacement, and when to choose each in Caesar II software design, using 25% (15% near critical equipment) limits.

  • Components of a Spring Hanger7:58

    Explore spring hanger components, including load plate, hanger rod, spring assembly, upper and lower attachment points, adjustment mechanisms, coatings, nameplate and identification, safety features, and accessories for piping load support.

  • Design and Selection of Spring Hangers13:53

    Learn to design and select variable and constant spring hangers using the Carpenter and Peterson catalog, evaluating hot and cold loads, displacement, and overtravel for proper size and rate.

  • Caesar II Case Study of Variable and Constant Spring Hanger Design and Selection23:49

    This caesar ii case study demonstrates using a bottom type variable spring hanger to mitigate tank settlement, selecting l1 and l2 load cases and comparing constant versus variable springs.

  • Certain Salient Points to Remember13:26

    Perform technical bid evaluations for spring hangers, checking hot and cold loads, rate variability, and height with attachments using Caesar II's extended range, cold load, and hot load options.

Requirements

  • Basic Knowledge of Pipe Stress Analysis in Caesar II software

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.
