4 s LABORATORY ANALYSIS - 3 TUBES 1 GENERAL REQUIREMENTS GPUN: 1. PERFORM IN GENERATOR EDDY (ONSITE) CURRENT INSPECTION
- 2. PERFORM OUT OF GENERATOR EDDY CURRENT INSPECTION EITHER ONSITE OR AT LABORATORY LABORATORY: 1. ANALYZE AT LEAST THREE (3) EC INDICATIONS (OFFSITE) AS IDENTIFIED BY GPUN.
- 2. DOCUMENT THE AS-RECEIVED CONDITION OF THE TUBE SAMPLE BY PHOTOGRAPHY.
- 3. PERFORM EDDY CURRENT TESTING OF TUBE SAMPLES IN ACCORDANCE WITH GPUN PROCEDURES.
- 4. MACROSCOPICALLY CHARACTERIZE THE SURFACE TOPOGRAPHY AND MORPHOLOGY IN THE IMMEDIATE VICINITY OF EACH EDDY CURRENT (EC)
INDICATION.
- 5. MEASURE CIRCUMFERENTIAL AND/OR AXIAL EXTENT OF EACH CRACK, PIT OR OTHER DEFECTS ON TUBE SECTIONS IDENTIFIED BY GPUN FOR METALLURGICAL EVALUATION.
- 6. ANALYZE CRACK FACES AND CORRODED AREAS FOR CONTAMINANTS BY ESCA AND AUGER.
'O
, SAMPLE SECTIONING
- 1. SECTIONING SHALL BE DONE TO LIMIT
. DISTURBANCE OR CONTAMINATION OF THE EDDY CURRENT INDICATION. CARE SHALL BE TAKEN SO AS NOT TO CUT THROUGH ANY EC INDICATION.
- 2. INITIALLY, SELECTED TUBE SAMPLES SHALL BE SLIT LENGTHWISE TO EXAMINE THEIR ID SURFACES. PHOTOGRAPHS SHALL BE TAKEN WITH A HIGH-QUALITY CAMERA TO RECORD THE GENERAL CONDITION OF INTERNAL SURFACES. CLOSE UPS SHALL BE TAKEN OF ALL EC INDICATIONS, AS WELL AS CORROSION DAMAGE NOT DETECTED BY ECT.
- 3. THE INSIDE SURFACE OF EACH TUBE SHALL BE EXAMINED FOR CORROSION DAMAGE (CRACKS AND PITS) USING A STEREO MICROSCOPE. PARTICULAR ATTENTION SHALL BE GIVEN TO THE AREA OF THE SUSPECT DEFECT.
- 4. THE CIRCUMFERENTIAL/ AXIAL EXTENT OF EACH EC DEFECT SHALL BE MEASURED UNDER A STEREO MICROSCOPE WITH A RECTICLE MARKED OFF IN MILLIMETER OR MIL UNITS AND RECORDED. FOR THOSE INDICATIONS WHICH ARE NOT GOING TO BE ANALYZED BY MICROCHEMICAL METHODS FLUORESCENT DYE PENETRANT TESTING MAY BE USED TO HIGHLIGHT THE DEFECT FOR DIMENSIONING PURPOSE.
P
t f
. METALLOGRAPHY al M
- 1. METALLOGRAPHY SHALL BE PERFORMED ONATHREE EC INDICATIONS TO DETERMINE THE SIZE AND CHARACTERISTICS OF EACH INDICATION.
- 2. METALLOGRAPHIC SPECIMENS SHALL BE GROUND, POLISHED IN SMALL INCREMENTS OF ABOUT 10 MILS OR AS DIRECTED BY GPUN OVER THE ENTIRE LENGTH.0F THE DEFECT. MAXIMUM AXIAL AND RADIAL DIMENSIONS SHALL BE RECORDED FOR EACH INCREMENT. MEASUREMENTS SHALL BE MADE WITH A RECTICLE MARKED OFF IN MILLIMETER OR MIL UNITS.
'I
.i l
- 'SEM/ MICROCHEMICAL ANALYSES
- 1. ONE EC DEFECT SHALL BE EXAMINED IN THE SCANNING ELECTRON MICROSCOPE.
- 2. MICRO-CHEMICAL ANALYSES SHALL BE PERFORMED ON THE SURFACE SCALE AND THE MECHANICALLY OPENED IGA FACES. TECHNIQUES SHALL INCLUDE ENERGY DISPERSE X-RAY ANALYSIS (EDX) FOR ELEMENTAL COMPOSITION OF SURFACE SCALE AND DEPOSITS, AND ELECTRON SPECTROSCOPY (ESCA)
FOR IDENTIFICATION OF CHEMICAL FORM OF ELEMENTS IN SURFACE FILMS ON THE TUBE INSIDE DIAMETER AND IGA FACES.
