ULTRASONIC TESTING OF HIGH PRESSURE BLOW DOWN VESSEL

Inspection of nozzle welds of various diameters and thickness was performed under the auspices of TWI (U.K.) and the customers Inspection Engineer. The job was challenging due to the usual complications encountered with the constantly changing profile of each nozzle weld configuration and the added problems of physical restrictions and extreme heat inside the vessel.

Some Nozzle Welds were only accessible from inside of the vessel, and this particular weld (pictured above) had an additional restriction by way of a Baffle Plate. The technician could only reach the weld area by inserting his head between the Baffle Plate and vessel shell. This made hand and eye coordination extremely difficult.
