As a pioneer in the field of non-destructive testing (NDT) and asset management, TechCorr uses sophisticated methods and careful analysis to tackle challenging problems and guarantee the integrity and security of vital infrastructure. In this industry, it is critical to implement maintenance procedures that are exact, dependable, and proactive. Our most recent examination and assessment of a kerosene piping system, known as SK-077, highlighted the vital significance of thorough inspection procedures and focused fixes.
The inspection of the SK-077 system was conducted in accordance with the latest API 570 standards, focusing on the segment from the tower T1 to the pumps P-4 (P-4A, P-6A) within a crude plant. TechCorr’s highly skilled NDE inspectors thoroughly inspected the system and found that it had been subjected to difficult circumstances, including fire damage, and excessive wear.
The Challenge: The primary areas of concern at pipe rack support bases were burned coatings, insulation failures, and general corrosion. Each of these problems needed to be thoroughly inspected and dealt with right away.
Ultrasonic testing (UT), one of the crucial methods used, showed significant wall loss in several places, with results showing a drop of almost 60% from the nominal thickness. Particular condition monitoring locations (CMLs) were found; the worst degradation was seen at CMLs 6, 7, 10, 11, 12, and 13. Our engineers were able to create a focused maintenance plan and identify the locations that needed repairs the most urgently thanks to this data.
TechCorr experts suggested several remedial steps to fix these problems. These included applying sophisticated coating systems to guard against more corrosion and environmental exposure, replacing deteriorated piping sections, and installing wear pads to stop crevice corrosion at support contact areas. Additionally, the team recommended installing support gussets at the pump’s inlet and outlet connections to lessen stress and vibration-induced damage.
TechCorr’s approach extends beyond immediate repairs to include preventive measures. For example, TechCorr’s team stressed the significance of using high-quality insulation materials and appropriate sealing techniques to avoid moisture intrusion, a typical source of corrosion under insulation (CUI), in order to combat continuous corrosion under insulation. Regular inspection intervals were also set, with UT surveys every 10 years and visual examinations every five years, to guarantee ongoing monitoring and prompt intervention.
The assessment also made clear the necessity of better site drainage and housekeeping in order to stop environmental variables from accelerating the deterioration of the infrastructure. TechCore experts recommended carefully cleaning and recoating the affected parts in compliance with NACE SSPC-SP-3 requirements, which are specifically tailored for the maritime climate of the site, in order to extend the lifespan of the components.
TechCorr proved its dedication to guaranteeing the efficiency, dependability, and safety of crucial piping systems by implementing these cutting-edge NDT procedures and thorough maintenance plans. In addition to resolving the immediate challenges, our skilled team’s ability to recognize and handle these issues successfully laid the groundwork for improved long-term asset management, highlighting TechCorr’s position as a leader in the sector.
