Basic dataStandard ID: GB/T 27698.5-2011 (GB/T27698.5-2011)Description (Translated English): Test method for the performance of heat exchangers and heat exchange element -- Part 5: Heat transfer tube for tubular heat exchangers Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: J75 Classification of International Standard: 27.060.30 Word Count Estimation: 10,176 Date of Issue: 2011-12-30 Date of Implementation: 2012-06-01 Quoted Standard: GB 151; GB/T 27698.1 Regulation (derived from): Announcement of Newly Approved National Standards No. 22 of 2011 Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary: This standard specifies the shell and tube heat exchangers, heat exchange liquid liquid without phase change, vapor liquid phase-change condensation, evaporation flow boiling pool boiling with phase transitions and phase-change test evaporation conditions of heat transfer and fluid resistance methods for measuring performance. This section applies to a single component of the test fluid or considered only for single-component liquid liquid, gas liquid. This section considers only the material thermal resistance tubes, the inner and outer tubes are not considered fouling resistance.

Heat exchangers and heat transfer device performance test methods Part 5. shell and tube heat exchanger heat transfer tubes1 ScopeThis section GB/T 27698 specifies the shell and tube heat exchanger heat transfer tubes liquid - liquid without phase change, vapor - liquid phase change condensation, flow boiling Evaporation phase change and pool boiling evaporation phase change heat transfer test conditions and fluid resistance performance test methods. This section applies to the test fluid is a single component or as a single component only consider liquid - liquid, vapor - liquid. This section only consider material thermal resistance of heat transfer tubes, the heat transfer tubes are not considered within the outer fouling resistance.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB 151 shell and tube heat exchangers GB/T 27698.1 heat exchangers and heat transfer device performance test methods - Part 1. General requirements3 Requirements3.1 should control the heat transfer tubes made of single tube heat exchanger prototype. 3.2 prototype design data and test parameters. a) type of heat transfer tubes; b) heat exchange material; c) heat transfer tubes geometry; d) test length; e) equivalent diameter; f) flow channel cross-sectional area; g) heat transfer area. Above design data and test parameters which determine the method of calculation should be based according to GB 151 and GB/T 27698.1 requirements get on. 3.3 Test procedure 3.3.1 no phase change liquid - liquid heat exchanger 3.3.1.1 no phase change liquid - liquid heat exchanger testing system shown in Figure 1. 3.3.1.2 before the test, you should check the prototype, measuring instruments as well as the reliability of the pipeline. 3.3.1.3 After the running, should be within the exhaust gas net prototype, so the prototype under test completely filled with fluid and operating conditions are adjusted to Standard test conditions. 3.3.1.4 After the standard test conditions and stable operation of 30min, should be tested according to the following test requirements. The flow rate of a) from both sides of the fluid flow rate variation 0.5m/s ~ 1.5m/s, etc., change interval should be not less than 0.2m/s; b) a fixed flow rate side (hot side or cold side) of the fluid at 1.0m/s, the other side of the flow rate of the fluid should be 0.5m/s ~ 1.5m/s variable Of change interval should be not less than 0.2m/s; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 27698.5-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 27698.5-2011_English as soon as possible, and keep you informed of the progress.
