1 Scope 1.1 This recommended practice describes procedures which may be used to “prove-up” the depth or size of imper- fections. Included in this practice are the recommended pro- cedures for ultrasonic prove-up inspection of new pipe using the Amplitude Comparison Technique and the Amplitude- Distance Differential Technique for evaluation of 1) surface breaking imperfections in the body of pipe and 2) surface breaking and subsurface imperfections in the weld area of electric resistance, electric induction or laser welded pipe and 3) surface breaking and subsurface imperfections in the weld area of arc welded pipe. For the purpose of this document, pipe is defined as including casing, plain-end casing liners, tubing, plain-end drill pipe, line pipe, coiled line pipe, pup joints, coupling stock, and connector material. 1.2 Prove-up inspection is a method to evaluate the radial depth of imperfections detected by automated inspection equipment or other nondestructive testing (NDT) tech- nique(s) to determine acceptance criteria compliance with the appropriate API specification. 1.3 The recommended prove-up practices established within this document are intended as a guide, and nothing in this guide should be interpreted to prohibit the agency or owner from supplementing the guide with other techniques or extending existing techniques. 1.4 This RP covers evaluation, a description of inspection methods, calibration and standardization procedures, and inspection personnel requirements for prove-up. 1.5 Appendix A of this document is provided as an over- view to inform the user of the basis for the techniques out- lined in this RP. 1.6 Appendix B of this document provides a procedure for determining if imperfections are surface breaking and a for- mula for calculating the sound path distance for a circumfer- ential or axial scan of a curved surface and a sample look-up table.
3.6 angle beam: An inspection method in which the angle of incidence or refraction is other than perpendicular to the surface of the test object being inspected. This includes the use of shear waves and longitudinal (compression) waves. 3.7 angle beam block: A specified type of reference standard used for the angle beam method. 3.8 angle of incidence: The included angle between the beam axis of the incident wave and a line perpendicular to the surface at the point of incidence. 3.9 angle of refraction: The included angle between the beam axis of a refracted wave and a line perpendicular to the refraction interface. 3.10 API: Abbreviation for American Petroleum Institute, headquartered in Washington, D.C. 3.11 artificial discontinuity: See reference indicator. 3.12 ASNT: Abbreviation for American Society for Non- destructive Testing, headquartered in Columbus, Ohio. 3.13 ASTM: Abbreviation for American Society for Test- ing and Materials, headquartered in West Conshohocken, Pennsylvania. 3.14 axial scanning: Scanning for imperfections with a transverse orientation. The transducer is aligned with the lon- gitudinal axis of the pipe. 3.15 calibration: The comparison of an instrument with, or the adjustment to, known reference(s) often traceable to the National Institute of Standards and Technology (NIST). 3.16 certification: A written declaration stating compli- ance with stated criteria. 3.17 circumferential scanning: Scanning for imperfec- tions with a longitudinal orientation. The transducer is aligned perpendicular with the longitudinal axis of the pipe. 3.18 couplant: A material (usually a liquid) used between an ultrasonic transducer and the test specimen to conduct ultrasonic energy between them.
3.27 gate: An electronic device for monitoring signals in a selected segment of the trace on an A-scan display. 3.28 gate start: The position along the A-scan display where the gate begins. The displayed value may be expressed in inches or microseconds. 3.29 gate width: The length of the gate along the A-scan display as measured from the gate start. The displayed value may be expressed in inches or microseconds. 3.30 IIW block (International Institute of Welding): See angle beam block. 3.31 imperfection: A discontinuity or irregularity in the product. For exact definitions and illustrations of specific imperfections, see API Std 5T1. 3.32 indication: A response from nondestructive inspec- tion that requires interpretation in order to determine its signifi- cance. 3.33 instrument delay control: An electronic circuit used to adjust the start of the time-base. May also be referred to as the zero control. 3.34 instrument material velocity control: An elec- tronic circuit used to adjust the length of the time-base rela- tive to the velocity of the material being inspected. May also be referred to as the range or calibrate control. 3.35 inspection: The process of examining pipe for pos- sible defects or for deviation from established standards. 3.36 inspector: A person who is qualified and responsi- ble for one or more of the inspections or tests specified in this document. 3.37 k factor: A derived factor for calculating depth when using the Amplitude Distance Differential Technique (ADDT).
