PREFACE
• Piping Stress analysis is a term
applied to calculations, which
address the static and dynamic
loading resulting from the effects of
gravity, temperature changes,
internal and external pressures,
changes in fluid flow rate and
seismic activity.
• Codes and standards establish the
minimum requirements of stress
analysis.
APPLICATION
• Safety of piping and piping
components.
• Safety of connected equipment
and supporting structure.
• Piping deflections are within
the limits.

CONCLUSION
OF C+ IND CASE STUDY:1
• As per Input support location is
not identified so, the deflection
increases and henceforth
allowable stress on the pipe
increases subjected to
temperature and pressure
• Report based on the input as
follows
• Analyzed reports shall be
submitted in the required
format of the customer.

C+IND CASE STUDY:2
• Case study 2 comprises the same
input as case study 1 excluding
the pipe supports and hangers.
• Restraints input (at specific &
maximum displacement node
point from case study 1) is as
follows.

CONCLUSION
OF C+ IND CASE STUDY:2
• The Analysis of case study 2 is
within allowable stress condition
since, the absorption of the loads
are carried by supports and
hangers.
• The supports and hangers acts
as guides to the pipe routing and
also deflects the loads acting on
the pipe.
