Considerations for the piping designer before starting your piping design on a Column.
From the basic layout and engineering specifications:
· Minimum access, platform width, walkways and headroom requirements.
· Handling Facilities for the column internals, line blinds, relief valves, manhole covers.
· Max. rise of ladders.
· Requirements of piping systems.
· Min. line size and number and location of hose stations.
· Access requirements for valves and instruments.
From Design Standards:
· Details of ladder dimensions
· Ladder and platform position - step through or side step landings.
· Toe plate, hand rail and safety gate details.
From P&ID and Tower Technical Specification:
· Process data showing interconnected equipment and piping
· Pipe sizes, specs and components
· Steam tracing and insulation thickness
· Tower elevations and differences in related equipment levels.
From the Plot Plan:
· The physical location of a column and it relationship to other equipment.
· Main access
· Main pipe rack or pipe run
· Pump locations.
From the Instrument Standards:
· The location of instrument connections on the column for gauges, level controllers and level alarms
· Location of pressure and temperature connections.
From the column fabrication drawings:
· Diameter and height of the column.
· Dimensions and details of column internals.
· Process Piping Connections
· Pump, exchanger, drum drawings showing details of of process equipment adjacent to, or supported on the column itself.
