Course details

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:

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

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

2. Operating Temperature Range:

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

3. Installation Constraints:

o 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.

Questions and Answers

Q: You're modeling a hot overhead line in Caesar II and searching "Caesar II spring hanger selection constant vs variable for hot lines". The line sees 210 mm vertical thermal growth at the support. Space envelope is tight but no dynamic load case is specified. What support type fits the duty?

A: Governing principle: support selection is driven by allowable load variation over the full operating travel. Applied here: 210 mm travel is high but still serviceable with a variable spring if the load variation remains within acceptable limits and no sensitive equipment is involved. Tight space doesn't negate variable springs; it constrains can size. The constant spring distractor traps engineers who remember displacement thresholds without checking actual load variation or connected equipment sensitivity.

Q: During a turnaround walkdown you're googling "estimate spring hanger load from pipe size without Caesar II". A DN300 carbon steel line, 12 m between supports, carries liquid hydrocarbon at 800 kg/m3. Insulation is 50 mm mineral wool. What's the order-of-magnitude vertical load the spring must carry?

A: Governing principle: spring sizing starts from sustained load, not operating load, using simple weight per length estimates. Applied here: DN300 steel plus liquid and insulation lands near 1.6–1.8 kN/m, giving ~20 kN over 12 m. That's enough to screen spring can sizes before Caesar II refinement. The 10 kN option catches engineers who drop fluid and insulation, a common adjacent-discipline shortcut.

Q: While reviewing supports you're searching "ASME B31 spring hanger load variation requirement". A variable spring shows 28% load variation hot to cold. No rotating equipment is connected. How do you judge acceptability?

A: Governing principle: code intent is to limit harmful load transfer, not to enforce a universal numeric cap. Applied here: ASME piping codes allow engineering judgment; 28% is commonly tolerated on noncritical lines if stresses and nozzle loads are controlled. The hard-limit distractor appeals to engineers who confuse vendor guidelines with enforceable code rules.

Q: Pre-commissioning you're checking supports and searching "field check spring hanger cold load setting procedure". The plant is still cold. What sequence avoids mis-setting the springs?

A: Governing principle: spring hangers are set cold to achieve the correct hot condition after thermal growth. Applied here: confirming tag data, setting cold load, and documenting elevation before startup prevents hidden bias and overload on heat-up. The mid-travel option traps engineers who know travel matters but apply it at the wrong stage.
