Testing and Measuring Articles

Whether you need to measure dimensions or perform some sort of flaw detection on sheet, tube, or pipe, you'll find what you need in this technology area. It discusses measuring coordinates, diameters, and hardnesses; flaw detection using eddy current, ultrasonic, radiographic, and X-ray systems; and using a few other equipment types, such as vision systems and material composition analyzers.

Inclusions caught with PAUT

February 17, 2014

By:

Tube and pipe producers are familiar with ultrasonic testing (UT) which, as the name implies, uses high-frequency sound waves to find discontinuities in tube and pipe. While conventional UT is effective for testing raw materials with simple shapes—round tubing, rectangular billet, and rectangular plate—complex shapes such as castings and assemblies need something more. Phased-array ultrasonic testing (PAUT) gets the job done.

Electronic sensors augment error-proofing, quality control programs

December 2, 2013

By:

Manufacturing is changing—the old hands are retiring, and many left the industry suddenly in the wake of the 2009 downturn. The workforce is smaller and less experienced than before, yet the demands for quality and consistency have never been higher. Electronic sensing and measuring systems can help with inspection and error-proofing in this demanding situation.

Taking NDT as far as it can go - TheFabricator.com

Taking NDT to the end of tube, pipe

September 10, 2012

NDT systems are limited in how close to the end of a tube or pipe they can test successfully. They rely on electromagnetic or ultrasonic waves to flow through the tube or pipe, and the end represents an abrupt change in the wall’s characteristics, making the test results difficult to interpret near the pipe or tube end. A new system overcomes the conventional obstacles by aiming clockwise, counterclockwise, and transverse transducers at a single point of entry. A timed delay based on the 1-kHz transmit frequency prevents the signals from interfering with each other, enabling the receiver to interpret the results accurately.

Testing OCTG

September 9, 2011

By:

Hydrostatic testing of oil country tubular goods is done twice—once to test the weld seam, then again after the item is threaded and a coupling attached. Most hydrostatic testing systems test the entire length of the pipe both times, but a new unit, the box-end hydrostatic tester, tests just the threaded portion and the coupling, reducing the time and water needed for the second test.

How metal production affects the welding process

January 11, 2011

By:

Welders may recognize that when porosity is present, the cause isn’t always the shielding gas, welding filler, or operator error. It can be caused by the steel production method, which can introduce porosity and other flaws.

Evaluating product integrity with eddy current

October 11, 2010

By:

Tube and pipe producers and fabricators who are familiar with the conventional encircling coils used in eddy current testing might be interested in learning more about this technology. Eddy current can be used on a variety of product shapes and does more than detect cracks. It can detect relative hardness and hardness changes (good for verifying heat treatment) and the presence or absence of physical features such as splines and threads.
