Case Study: Pressure Equipment

A chemical company needed to perform observation and oversight of a supplier for a new heat exchanger. Visual inspections of the welds and pressure boundary shell were conducted prior to the Hydrostatic leak test of the exchanger, but no other tests or examinations were conducted.

Solution

The company hired BAY Technical Associates for a more thorough look. During our inspection, we noted several deep grooves from removed welded alignment bars. Upon conferring with our client, it was determined that repairs were needed, and further Non-Destructive Examinations were needed to ensure the shell's structural integrity. The BAY Technical inspector informed the vendor of their client's request, remained on site until the repairs were complete and a successful Hydrostatic leak test was performed to meet code and our client's requirements.
