Analysis Non-Destructive Test of API Five Layer Carbon Steel Pipe Weld Test

Abstract

This article presents a comprehensive analysis of non-destructive testing methods applied to the welding of American Petroleum Institute five-layer carbon steel pipes in gas piping systems, with a focus on the Integrated Terminal Surabaya. The study emphasizes the critical role of welding processes, particularly Shielded Metal Arc Welding, in ensuring the structural integrity and safety of gas transportation infrastructure. Adhering to industry standards such as American Society of Mechanical Engineers IX, the research evaluates the effectiveness of non-destructive testing techniques, specifically radiography and dye penetrant testing, in identifying weld defects such as porosity and incomplete fusion that may compromise the reliability of welded joints. Radiographic examinations utilize gamma rays to produce detailed images, while dye penetrant tests highlight surface irregularities, both of which are essential for maintaining operational safety in high-pressure environments. The findings reveal that meticulous quality control measures, including pre-weld inspections, real-time monitoring, and rigorous post-weld evaluations, are paramount in preventing catastrophic failures. This study underscores the importance of adhering to established standards and implementing effective non-destructive testing practices to enhance the safety and efficiency of gas piping systems, thereby mitigating risks associated with gas transportation.
