Give each tube a location identifier
A multicyclone arranges several separation elements in a common housing [1]. Build a row and column map from the installed drawing. Mark the inlet side and inspection viewpoint. The same number must identify the same element in photographs, work orders and the next outage report.
Separate inspection findings by mechanism
Record deposits, missing pieces and visible wear in distinct fields. Keep inaccessible areas marked uninspected. EPA describes the role of the gas path and particle characteristics in cyclone separation [2]. An observed deposit helps locate a restriction. It cannot by itself quantify the bank's total outlet performance.
Define the closeout record
For each repair, save the part identity, orientation, inspection method and accepted drawing revision. Link the restored tube positions to the post-maintenance operating record. A position map makes recurrence visible and gives the supplier a way to compare repeated damage with the inlet arrangement.
FAQ. Can a whole-unit inspection replace the position map?
A general inspection describes the equipment condition. A position map is needed when the finding or replacement must be traced to an individual tube.
