Considerations for the Piping Designer

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.

·         Manholes

·         Process Piping Connections

·         Pump, exchanger, drum drawings showing details of of process equipment adjacent to, or supported on the column itself.
