Steps to Do Heat Exchanger Piping

  1. Gather Mechanical Specifications: Collect the mechanical specifications of the heat exchanger.
  2. Analyze P&ID: Study the P&ID (Piping and Instrumentation Diagram) around the heat exchanger to identify its connections to other equipment, such as columns or reactors.
  3. Note Process Requirements: Take note of any special process or functional requirements, along with specific arrangement details, such as level or height differences relative to other connected equipment like pumps.
  4. Verify Nozzle Schedule: Review the nozzle schedule, including its position on the equipment, and verify it against the P&ID.
  5. Sketch Relative Location and Level: Create a sketch depicting the relative location and level of the heat exchanger. Determine the required tube cleaning space for shell and tube heat exchangers, as well as the maintenance space for tube bundle removal.
  6. Locate Control Valve Stations: Identify the locations of control valve stations for both shell-side and tube-side fluids.
  7. Designate Flanged Joint Locations: Determine the placement of flanged joints to facilitate heat exchanger replacement or maintenance.
  8. Consider Stream Directionality: As a general rule, cooled streams should flow downwards, while heated streams should flow upwards. This arrangement is mandatory when there is a phase change, desirable when streams are liquid, but not crucial for gases, vapors, or situations without superheating or supercooling.
  9. Prevent Piping Interference: Ensure that piping does not obstruct heat exchanger removal, either horizontally for bundle pulling or vertically for complete exchanger removal.
  10. Ensure Instrument Accessibility: Verify that locally mounted instruments, such as pressure indicators (PIs), temperature indicators (TIs), sight glasses, and level indicators, are visible from access aisles, and that valves are accessible from the aisles.
  11. Mark Piping Supports: Indicate the locations and arrangements of piping supports on the piping study.
  12. Maintain Valve Accessibility: Ensure adequate accessibility for operating all valves. Verify that clearances meet the recommended minimum requirements.
