Inspection for blockage in the U-tubes of heat exchangers
Thread Content
A power plant has just installed large heat exchangers, and the owner needs to check whether there is any blockage at the 90-degree bends in the U-tubes. There are a great number of heat exchange tubes in this area; what are some quick ways to conduct such inspections? Thank you all

Using high-pressure water should be a relatively effective method.
