Intent 1:
To limit the probability that:
- internal stress or mechanical damage will lead to failure
of the piping,
- piping and fittings will leak prematurely or
- a chemical reaction with the liquid will lead to premature
corrosion of the piping, which could lead to failure of the piping.
This is to limit the probability of
the escape of liquid, which could lead to the ignition of vapour from
a nearby ignition source, which could lead to harm to persons.
