Signals can be produced by discontinuities located either on the external or internal surface of the tube or by discontinuities totally contained within the walls. On-line eddy current examining would not be subject to end effect.

Historical Version e2443 – view previous versions of standard. The effect of foreign materials on the tube surface and signals due to tube supports are typical of the factors that must be considered.

The illustration above shows a standard lineset with suction line insulated see chart for available insulation thickness. Currently there is no ASTM specification for insulated copper tube. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but atm not provided as part of the standard.

For such applications, the technical differences associated with the use of internal probe coils should be recognized and accommodated. BoxArlingate Ln.

For such applications, the technical differences associated with the use of internal probe coils should be recognized and accommodated. AIAWilson Blvd. Since the density of eddy currents decreases nearly exponentially as the distance from the external surface increases, the response to deep-seated defects decreases. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

The liquid line is normally not insulated, but can be special ordered astj be insulated. The effect of foreign materials on the tube surface and signals due to tube supports are typical of the factors that must be considered. See E for additional details regarding the in-situ examinations using internal probes. Since the density of eddy currents decreases nearly exponentially as the distance from the external surface increases, the response to deep-seated defects decreases.

Note 1-This practice may be used as a guideline for the examination, by means of internal probe test coil systems, of installations using tubular products where the outer surface of the tube is not accessible. Relevant indications are those which result from nonacceptable discontinuities.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
