Root node of the lack of penetration tube defects, should be measured defect echo amplitude RBJ-1 test block measured on the artificial echo amplitude (UF) the difference between dB, namely for UF who dB.

On defect root is not welded tubular joints, should on determination of defect echo amplitude RBJ-1 block artificial echo amplitude measurement (UF) decibel difference between included UF dB.

To the pipe junction root penetration flaw, should not determine on the flaw echo scope RBJ-1 briquette to measure artificially between echo scope (UF) a decibel interpolation, the idea makes UF gentleman dB.

The roots of the managed nodes should be measured not welding defects and shortcomings, echoes RBJ-1 test piece rate at UF artificial detection range () echoes the decibel level of the margin between UF taxi dB, counted.

On defect root is not welded tubular joints, should on determination of defect echo amplitude RBJ-1 block artificial echo amplitude measurement (UF) decibel difference between included UF dB.
