Performing Proper Hydrotests After Tube Bundle Replacements

Are you performing proper hydrotests after Tube Bundle Replacements?

I’ve seen some interesting ways Owner/Operators try to save money on new equipment costs. Opting for leak tests and proof tests instead of performing ASME Code required hydrotests has become increasingly popular, especially when it comes to tube bundle replacements. The problem with not performing a full hydrotest at the fabrication shop is that the requirement to field hydrotest is hidden away as a remark at the end of the U-Form and is easily ignored. 

Owner/Operators have not yet made the connection between the frequency of their tube bundle replacements and the lack of proper hydrotest for the tube bundles they are replacing. Properly hydrotested tube bundles will last longer. The most cost effective way to perform your hydrotest is most often at the fabrication shop. Please pay your fabricator for a full hydrotest.
