Pipe Stress Analysis in Piping System
" PIPING SYSTEM " are composed of piping, valves, fittings and other accessories which have the objective of transporting fluids (Liquid or Gas) between different points of the industrial site.
Considering the restraints imposed by the supports OR/AND equipment's nozzle every piping has the mechanical behavior of a structure, which means that it's subject to traction, shear, torsional , etc.
Main Acting Loads on Piping
* Structural

Main Acting Loads on Piping
* Structural
- Piping Weight
- Fluid Weight
- Thermal Insulation Weight
- Internal Coating Weight
- Valve and Accessories Weight
- Thermal Contraction / Expansion of Piping
- Thermal Contraction / Expansion of Equipment
- Intermediate Restrictions
- Internal Pressure
- External Pressure
Piping Supports
Pipe Supports and hangers are devices which transfer the loads from the pipe or the structural attachment to the supporting structure or equipment. They include rod hangers, Spring hangers, Sway Braces, Turnbuckles, Struts, Anchors, Saddles, Rollers, Brackets, and Sliding Supports, Structural attachments are elements that are welded, bolted, or clamped to the pipe, such as clips, lugs, clamps, clevises, and stops.
Vibration - Theoretical Definition
- Any motion that repeats itself after an interval of time is called vibration or Oscillation.
- The vibration of a system involves that transfer of its kinetic energy to potential energy , Alternately.
- If the system is damped, some energy is dissipated in each cycle of vibration and must be replaced by an external source if a state of steady vibration is to be maintained.
