establishing thickness measurement locations (TMLs) within an injection
point circuit? ( Correct answers ) Appropriate locations on the connected
vessels
When taking thickness measurements, at injection points, what are the
preferred methods of obtaining these measurements? ( Correct answers )
Radiography and or ultrasonic
Periodically, inspections of an injection point circuit should include more
extensive inspection. What are the recommended limits of this extended
inspection? ( Correct answers ) Beginning 12 inches upstream of the
injection nozzle and continuing for at least ten pipe diameters
downstream of the injection point
