Mechanical Seal Performance And Related Calculations
MetadataShow full item record
A short collection of mechanical seal performance calculations has always been included in the earlier and current editions of the seal standard API 682 and the co-branded version of ISO 21049. The new draft of the Fourth Edition of API 682 and the planned update of ISO 21049 include a significantly expanded version of these calculations plus associated explanations in its Annex F. The new Annex topics pay particular attention to subsections covering piping plans for dual seal configurations. This tutorial is intended to present some new material on leakage management and dual seals, review some existing Annex F topics, and include sample calculations. Some the topics covered include: Leakage management; Seal face generated heat; Heat soak; Seal flush flow rate; Plan 2 and 53A Piping systems curves; Flush flow rates for Arrangements 3CW seals at different temperatures; Piping Plans 53A and 53B operations and alarm strategy.
