Welcome to the home page for the CRE Subcommittee on Heat Transfer Equipment (SCHTE). This site offers information on upcoming meetings, allows questions to be posted for the upcoming roundtable discussions, and provides information on the status of standards and due dates for documents managed by the SCHTE. Documents under development and revision are also available for review. Rosters may be posted for information and use among the subcommittee and should not be distributed outside of the members.
Mission: The SCHTE prepares, reviews and updates relevant standards, provides forums for keeping abreast of industry technology, maintains liaison activities with other standard-writing bodies, sponsors general interest sessions and provides the US input to related standards in ISO and IOGP.
SCHTE is divided into two main groups- fired and unfired equipement, with unfired comprised of tubular and non-tubular exchanger groups.
The following documents are under the purview of the SCHTE:
