Building a cylinder-bank supply station: what gets reworked

Cylinder-bank supply stations tend to be reworked in a few predictable places. Foundations and loads: a full bank weighs far more than an empty one, so the base and anchor bolts must be checked at full load. Separation distances: the gaps between the bank area, the unloading area and the utilisation equipment must satisfy both codes and local requirements, and adjusting them later is very expensive. Fire protection and venting: the height and direction of vent stacks relative to neighbouring buildings must be fixed in advance. Filling connection: the connector type and pressure rating of the trailer or filling point must match the station manifold.

Operating mode also needs deciding up front: a permanent bank refilled on schedule by trailer, or containerised racks that rotate as a whole. The first costs less but means frequent refills; the second rotates flexibly but needs lifting equipment on site.
