Принадлежит: Individual

An ultrasonic probe encircles the perimeter of a target component to be ultrasonically tested and has a base and a pair of jaws pivotally mounted to the base at opposite ends of an arcuate inner surface of the base to encircle a target component with arcuate inner surfaces of the jaws as well. The inner surfaces form a coupling fluid chamber with an outer surface of the target component. Front and rear sets of seals connected to and extending along front and rear portions of the arcuate inner surfaces seal the chamber so that it can retain a coupling fluid such as water. An arcuate set of ultrasonic transducers is connected along at least one but preferably all of the arcuate inner surfaces for transmitting ultrasonic signals to the coupling fluid chamber and into the target component.

Visualization of Tests on Swing Type Check Valve Using Phased Array Sequence Scanning

Номер: US20120180570A1
Автор: Hector Diaz, Jesse R. Delgado
Принадлежит: IHI Southwest Technologies Inc

Computers with proper programs generate signals in phased array sequence. In pulsers with delays, signals are fed through a multiplexor into multiple water wedges attached to a valve being tested. For a sequential operation of the valves from the open to the closed position, ultrasonic signals are transmitted through fluid contained in the valve and reflected back through piezo-electric crystals to the multiplexor. By summation and merger of the signals, an image can be developed of the operation of the valve to determine if the valve is operating properly. By using multiple water wedges and pass visualization software, the operator can see exactly how the valve is functioning, which information can be stored for inspections or maintenance.

A phased array ultrasonic probe may be mounted to a component to be inspected for wall thickness on an apparatus that includes a split ring adapted to be magnetically held in place on the component. In particular, the probe may be mounted to a carriage connected to the split ring in a manner that allows the carriage to rotate around the split ring while the probe is in operation. Between the probe and the component, a transducer shoe defining, by a flexible membrane, a cavity and an aperture. Conveniently, the construction of the flexible membrane allows wall thickness measurements to be acquired in portions of the component that have complex topography, such as welds. The apparatus is installed on an adaptor assembly for inspection of straight section of pipes. This adaptor assembly is not used in absence of straight section. By acquiring data from multiple output pulse transmitted at multiple incidence angles, processing software may conveniently produce an accurate wall thickness map of the area of interest on the component.

The flaw detection probe is translated along a scan direction. The flaw detection probe emits an ultrasonic beam such that the position upon which the ultrasonic beam converges coincides with the center of curvature of the curve of the outline of the cross section of the subject at the scan position, receives the resulting reflected beam, and estimates the length of a flaw in the circumferential direction of the subject. In addition, the estimated length of the flaw is corrected using a correction coefficient corresponding to the distance between the center of curvature of the reference scan position and the center of curvature of the scan position in the thickness direction of the subject.

Visualization of Tests on Swing Type Check Valves Using Phased Array Sequence Scanning

Номер: US20150096380A1
Автор: Delgado Jesse R., Diaz Hector
Принадлежит: IHI Southwest Technologies,Inc.

A computer with a proper program generates a phased array sequence of signals. In a pulser with delays, the signals are fed through a multiplexor into multiple water wedges that are attached to a valve being tested. For a sequential operation of the valves from the open to the closed position, ultrasonic signals are transmitted through the fluid contained in the valve and reflected back through piezo-electric crystals to the multiplexor. By summation and merger of the signals, an image can be developed of the operation of the valve to determine if the valve is operating properly. By comparing the signals received with a known standard for that type valve, proper operation, or lack thereof, of the valve under test can be determined. 1. A method of testing a valve while in use , said valve having a top and a valve body , said testing to determine if said valve is operating properly by comparing against standard waveforms for said valve , said method comprising the following steps:(a) first attaching a top probe of first piezoelectric devices to said top;(b) second attaching a lower probe of second piezoelectric devices to said valve body; said top probe being generally opposite said lower probe on said valve body;(c) sending a first start signal from a phased array acquisition control to a sending multiplexer to create first parallel signals;(d) feeding said first parallel signals to a sending pulser with delays to create first phased pulse signals;(e) connecting said first phased pulse signals to either (1) said top probe, or (2) said lower probe to generate first phased array sequential scanning signals in said valve;(f) receiving first reflected signals back where said first phased array sequential scanning signals were generated to give first reflected phase pulse signals;(g) converting said first reflected phase pulse signals in a receiving multiplexer into first reflected energy pulses;(h) changing said first reflected energy pulses in a receiver with delays ...
