GENERAL PIPING DESIGN
GENERL PIPING DESIGN
Feasibility study
Plans of route:
Environmental considerations.
Safety considerations.
Service conditions:
Substance to be transported.
Pressure, temperature, flow.
Surge conditions (liquid, two phase or dry gas).
Pressure drop, selection of pipe diameter.
Quality plan.
Why dose the feasibility study is
required?
Because it is the procedre to
determine th preliminary design
factor.

GENERL PIPING DESIGN
Preliminary Engineering
Design factor:
It is the ratio of the Hoop stress in the pipe at the design pressure
to the yield stress of the pipe material.
•It is a function of:
•Design pressure.
•Pipe diameter.
•Pipe wall thickness.
The design factor determines the probability of a pipeline rupturing
if it has been damaged or is corroded.
Why dose the preliminary engineering is
required?
Because it is the procedure to determine the
submission for construction authorization.
