Note
If the tank is empty and warm, vacuum space pressure will tend to be high
because of the release of gasses from the absorbent package inside the
vacuum space. Vacuum level should decrease to an acceptable level
when the liquid container is filled with cold product.
Note
An abnormally high vacuum reading without other evidence of vacuum
loss (excessive pressure, rapid venting, etc.) may be caused by a fault in
the gauging equipment or by improper operation of the equipment. Be
sure that the vacuum gauge tube are in good condition, and compatible.
Follow operating instructions carefully. Always be sure that the gauge tube
valve has been open for at least 30 minutes before taking a minute.
Foundation Details
Foundation bolt location dimensions and tank weights are shown on the
General Arrangement Drawing. The dimensions of mounting bolt locations
are for layout of the foundation only. This information should be used
along with tank weights from the General Arrangement drawing, and the
seismic zone requirements for your area and service. To determine
foundation requirements, local soil characteristics must be considered for
foundation construction as well as state and local codes and many other
factors. We recommend that you retain the services of a local civil
engineer to ensure all requirements of foundation construction are met.
Tank-Mounted Vaporizers
Many tanks, shipped with a vaporizer attached, are ready for service as
soon as the tank is installed. If additional vaporizers are ordered with the
tank, they are shipped separately with attaching hardware. A shut-off valve
should be installed downstream of the vaporizer. A line relief valve with
suitable capacity/service must be installed between the shut-off valve and
vaporizer.
Note
Installation of a suitable low-temperature shut-off device at the outlet of
the product vaporizer is recommended for systems in combustible gas
service or any system utilizing carbon steel piping.
