Abstract

In modern industry, pipelines play an important role, especially in the oil and gas sector. Pipes are susceptible to corrosion, especially those in aggressive environments such as PLTD Namlea, which is directly adjacent to the coast. Corrosion, as a natural process of metal degradation, is inevitable, but it can be controlled to extend the life of the pipe. This study measured the thickness of the pipes at PLTD Namlea using Ultrasonic Testing (UT) to determine the corrosion rate and remaining service life. Based on measurements, the minimum thickness of pipes at various measuring points (Measuring Points / MP) still meets the API 574 standard, which must not be less than 1.8 mm. The average corrosion rate ranges from 0.336 to 0.358 mm/year. These values affect the rate of degradation of the pipe and the remaining service life, which ranges from 5.5 to 6.1 years at various measurement points. Pipes that have a higher corrosion rate will have a shorter remaining service life. Overall, the pipeline at PLTD Namlea is still laid. Keywords: Pipe, Corrosion Rate, Remaining Life

Abstract

Ambon Peaker 30 MW. These pipes are prone to corrosion, especially if not protected by a coating, which leads to thickness reduction and shortens the operational lifespan of the pipes. The thickness measurement will be carried out using an Ultrasonic thickness gauge to determine the corrosion rate and the remaining life of the pipe. The standards referenced in data collection are the American Petroleum Institute (API) 570 and the American Society of Mechanical Engineers (ASME) B31.4. The research will be conducted by the author from August 28, 2024, to August 30, 2024, at PLTMG Ambon Peaker 30 MW, Salahutu District, Central Maluku Regency, Maluku Province. The research results show that the minimum thickness reduction indicates a corrosion rate of 0.228 mm/year at Thickness Measurement Location (TML) 17 and 18, while the maximum thickness reduction shows a corrosion rate of 0.564 mm/year at Thickness Measurement Location (TML) 3. Pipes with lower corrosion rates have a remaining life of 5.4 years, while pipes with higher corrosion rates have a remaining life of up to 31.9 years. In conclusion, coating protection is essential to reduce the corrosion rate and extend the service life of the pipes. Keywords: Pipe thickness, Corrosion rate, Pipe remaining life, Ultrasonic thickness gauge.

Abstract

ABSTRACTThe Ambon Peaker Gas Power Plant (PLTMG Ambon Peaker) is an electrical infrastructure facility powered by gas turbines, located in Waai Village, Central Maluku Regency, Maluku Province. The fuel oil storage tank used by the Ambon Peaker since 2019 is situated directly near the coastline, making it very vulnerable to damage, particularly from corrosion on its metal plate walls. Therefore, maintenance is necessary to prevent any unwanted workplace accidents. This tank stores fuel oil. The author conducted calculations for minimum thickness and corrosion rate to determine the remaining lifespan of the tank. The results indicate that the critical point is located at course 1, with a remaining lifespan of 121 years. This can be influenced by various factors, such as environmental conditions and fluid characteristics. Tank maintenance also needs to be considered to ensure the tank's reliability, allowing it to operate longer and preventing the need for corrective maintenance. Keywords: storage tank, corrosion rate, wall thickness, remaining life.
