Are there any regulations regarding the scope of application for leakage tests, airtightness tests, and seepage tests? Which equipment and pipelines require leakage testing? Which equipment and pipelines require a gas-tightness test? Which equipment and pipelines require leak testing? Chalk powder, kerosene – are they used for leakage tests? Are there any regulations in China regarding these three types of experiments at present?
Are leak tests also performed on large dust collectors and flue ducts in this way? Is it a bit difficult to do? Thin-walled structures with very low design pressure
As long as a weld requires a leak test, unless the operational difficulty is too high and the owner and designer agree to modify the testing requirements, a leak test is generally necessary
How to do it on-site? Are there detailed step-by-step instructions?
I’m mainly concerned about how to conduct a leakage test on the boiler’s smoke and air ducts Kerosene and chalk powder leakage tests: Since the smoke and air ducts of boilers are relatively large in volume and are subject to low working pressures, typically around ±30 kPa, there is generally no need to conduct leakage or airtightness tests. It seems that leakage tests are necessary instead, right? At present, there are no rigorous and authoritative construction and acceptance standards for smoke and air ducts in China
Thank you, the person above – the information provided is very detailed. But if it doesn’t fall under pressure pipelines or pressure vessels, what method should be used then?
Detailed information on the material composition, temperature, and pressure is needed to help you make a determination
Material: Clean industrial flue gas, with a temperature of 300–500°C and a pressure of ±30 kPa
