Recommended Spares and
Accessories
7.1
Spares scheduling
The following table is the recommended spares
holding, the number of recommended spares for
overseas customers are expressed in brackets and
take into account expected transport delays (see
table 12, figure 21).
Note - It is mandatory to replace 1st and 2nd stage
relief valves every 5 years.
Note - industrial regulators are recommended to
be replaced every 5 years. Although the medical
standards do not specifically identify the need to
replace the regulators within this time scale it is
considered good practice to do so. By replacing
the regulators when the relief valves are being
replaced, interruption of the gas supply is
minimised.
