Problems with the hydrostatic testing of heat exchange tubes

This post was last edited by jizhanwei22 on 2018-8-27 at 11:38. The heat exchange tubes (TA2) of a heat exchanger (Class I) were not subjected to a hydraulic test before leaving the factory; only an underwater airtightness test at 0.7 MPa was carried out. What will the local pressure vessel inspection agency do in this situation?

What are the material standards required for these heat exchange tubes?

For details, see NBT 47019-2011 \"Technical Requirements for Ordering Tubes for Boilers and Heat Exchangers – Part 8: Non-ferrous Metals, Titanium and Titanium Alloys\"
