In the scan images, the good weld appeared as a uniform line. The defective welds exhibited various discontinuities and a non-uniform appearance. Mechanical testing of the welds showed a marked decrease in properties, with reductions in the yield stress of one-third to one-half the value of the good weld.
A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
The use of HDPE in nuclear power plants requires extensive qualification and testing efforts to demonstrate that the material is safe under all design basis conditions. The U.S. NRC has raised concerns in the past with the use of HDPE related to butt fusion joint integrity, the ability to detect flaws in joints, and the potential for slow crack ...
Magnetic flux leakage (TFI or Transverse Field Inspection technology) is a magnetic method of nondestructive testing to detect corrosion and pitting in steel structures, for instance: pipelines and storage tanks.
The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.
PHOENIX — The U.S. military flew six victims from the tragic New Year's fireworks explosion in Honolulu to an Arizona facility due to limited bed space at Hawaii's only burn center, officials ...
The Consumer Financial Protection Bureau (CFPB) on Wednesday warned that credit card companies devaluing or canceling reward points, cash back or miles rewards programs may be breaking the law.
Two survivors of the bombing — each 100 or older — are planning to return to Pearl Harbor on Saturday to observe the 83rd anniversary of the attack that thrust the US into World War II.
