High density polyethylene (PE) pipeline has the characteristics of light weight, long service life, safety and convenience, etc., and fused HDPE pipeline overcomes the shortcomings of bonding and threaded connection, which is generally recommended for the
Three scanning modes of phased array
2019-11-08
Phased array inspection is getting more and more attention due to its efficient defect detection effect. Phased array inspection can accomplish tasksthat conventional ultrasound cannot, and the working speed of inspectors is greatly improved, which is in
Beam Deflection of Phased Array Probes
2019-11-26
Beam deflection and sector scanning are important factors to distinguish UT and phased array. And the performance of acoustic beam
deflectionplays an important role in the reliability of phased array inspection.In order to research the effects of freque
Friction stir welding (FSW), as a new solid phase welding technology, has better tensile, fatigue and bending properties than traditional welding methods.Welding process does not need gas protection, no dust and spatter and other advantages.However...
Application of DMA probes in nuclear reactor
2020-01-05
In nuclear reactor, zirconium and zirconium alloys, steel and nickel alloys, and aluminum alloys are the three main types of structural materials.........
Thickness Measurement
2020-01-10
There are various thickness-measuring methods used in a variety of applications, and a proper thickness measurement method helps complete inspection task more efficiently....
When we use phased array probes, sometimes side lobes and grating lobes are often generated that we do not want to see. The inspectors depend on the main sound path emitted by the probe for detection, and the grating lobe is generated because part of the
The Function of Wedges
2020-01-20
Wedges are generally used in phased array weld inspection, which have two main functions: (1) protect probes, (2) aassisted angle deflection.
for example:a phased array wedge of 55 degrees can be practically detected by electronic deflection....
What affects the TOFD probes?
2020-01-09
Time-of-flight di raction (TOFD) method is a sensitive and accurate method for the nondestructive testing to inspect welds and defects.The use of TOFD probes enable crack sizes to be measured more accurately.....
