PNTZ upgrades ultrasonic equipment for testing of pipes

The Pervouralsk New Pipe Plant--known as PNTZ--recently announced that its hot-rolled weldless pipes department has upgraded the Atlant ultrasonic flaw detection unit used for testing pipe ends.

The improvements make it possible to use ultrasonic technology to test the ends and body of the corrosion-resistant pumps using ultrasonic technology. Previously, the device was unable to test the body, Ural Business Consulting reports.

The upgrade included an adjustment to the operation algorithm of one of the main joints--the electroacoustic transducer tank.

A roller table was also installed on the unit to allow for the table to lift the end of the pipe and propel it forward after it is tested, decreasing the amount of time spent on standard 10-meter pipe testing. The reduction in time is significant, with tests being completed in 1.5 minutes as opposed to the previous seven minutes, according to Ural Business Consulting.

"To upgrade the device, roller stands, sensors, converters, and other kinds of equipment were bought," PNTZ Managing Director Alexander Belenkov said, Ural Business Consulting reports. "This required $90,000 worth of investments. Thanks to the jobs done, the time spent on testing pipe ends was reduced significantly and thus the department's productivity went up."
