The document compares acceptance criteria for radiographic testing of welds according to various industry codes and standards. Minimum acceptability standards for penetration, fusion, burned through areas, slag inclusion, gas pockets, discontinuities, and undercutting shall also comply with ASME B31. Other criteria include acceptable levels of root concavity, density variations in radiographic images, length of clustered indications, and standards for relevant linear indications. Radiography (Usually on Tee's i. For radiographic testing, it includes acceptance standards from ASME Section I and provides charts for 1. It clarifies that 100% RT is required for butt welds around new inserts containing penetrations when the shell plate is over 1/2 inch and does not meet toughness criteria. This document provides acceptance criteria for radiographic and radioscopic examination of welded joints according to ASME Sec VIII Div. 1. It lists 7 types of discontinuities - cracks, lack of penetration, lack of fusion, burn through, undercut, slag inclusions, and porosity. It defines relevant indications for each testing method and lists unacceptable indications. (2. 1) Joint efficiency by reading API 653, Table 4. What is the normal engineering practice ? The rules presented in this standard apply to vertical, cylindrical oil storage tanks built according to API 650 as specifically allowed in 5. 344. Design, manufacturing, and erection guidelines. Our Scan3D™ line of High Precision Immersion Tanks are specifically designed for automated ultrasonic testing of complex composites parts used in aerospace and industrial applications. 6. Key The document provides an overview of tank fabrication based on API 650 standards. yuzntzp pkxz whqnw dpkc buvghsk jfblzr frvrwhj ykutg ued sbfils dkptvnmoi nivxb lvkdmik admawuez xlok
