Solution required for hydraulic and airtightness testing of threaded lock rings
Thread Content
Guys, how do we carry out the hydrostatic test and airtightness test for high-pressure threaded lock-ring heat exchangers???
First, it is necessary to clarify the structure, as well as what the design standards and criteria for inspection and acceptance are; these should be specified in the drawings or outlined in the relevant standard references. Just do as instructed.
This is done to prepare for the teacher’s defense. The only information available is the test pressure, the normal structure of the high/low pressure thread lock rings, and the leakage test pressure. The test medium is air; moreover, the tube sheet is designed based on pressure differences. Now I need to develop a complete set of hydraulic testing procedures. It’s so difficult
Based on design experience, for a heat exchanger with a pressure difference design, a certain pressure difference should exist between the two shell sides during pressure testing. In my opinion, the original poster can search on Baidu, or wait for someone more knowledgeable to give an answer.
