Standards for Steam Surface Condensers
10th Edition, 2006

The Tenth Edition of the “Standards for Steam Surface Condensers” represents another step in the Heat Exchange Institute’s continuing program to provide Standards that reflect the latest technological advancement in the field of condensing equipment.

The Tenth Edition of “Standards for Steam Surface Condensers” has incorporated all information from the 9th Edition of Steam Surface Condensers as well as the Addendum to the 9th Edition. Also included in the 10th Edition is a new Table 3, which provides tube material and gauge correction factors. A sample thermal calculation has been added as Section 4.2.6. Table 6, entitled Materials for Condenser Tubes, has been updated and revised. Section 6.5.1.8 has been added to give users an example of sizing venting equipment as stated in Table 9. Section 7.0, Atmospheric Relief Devices, has been completely rewritten and updated. Information on clad tubesheets and condenser support systems has been incorporated into Section 8.0 of the standard. Section 9.0 has been expanded to include information on dimensional tolerances, shipping and site storage, field installation, erection superintendent duties, and post erection walk down. Appendix A has been completely revised from the previous edition. Appendix D has been updated, providing information on the procedure for calculating allowable nozzle external forces and moments in cylindrical vessels. Two new appendices, Appendix G and Appendix H, have been added to the 10th Edition. Appendix G is a troubleshooting guide that has been added to assist operators of steam surface condensers, and Appendix H is a newly developed HEI surface condenser data sheet. The HEI Condenser Section has also developed a Condenser Rating Program. Please visit the HEI website, www.heatexchange.org , for more information.

The Heat Exchange Institute anticipates a continuing program to extend and amplify the coverage presented in these Standards and this may require the periodic issuance of addenda to these Standards. As a result, users of these Standards should make sure that they are in possession of all such addenda by enquiry to the Heat Exchange Institute offices.

The Heat Exchange Institute solicits comments from all interested parties regarding areas where further treatment or more detailed treatment is desired or felt necessary. Contact the Institute at 1300 Sumner Ave., Cleveland, OH, 44115, or visit the HEI website at www.heatexchange.org.
