Abstract

Corrosion of API 5L Grade B steel is a common challenge in industries where the material is exposed to corrosive environments, such as saline solutions. To combat this issue, corrosion inhibitors are often used to protect the steel. This study explores the effectiveness of two inhibitors—Triethanolamine (TEA) and Cocamide DEA (CDEA)—in reducing corrosion on API 5L Grade B steel. By calculating the corrosion rate and inhibitor efficiency, we evaluated the protective properties of each substance. The results showed that TEA provided better corrosion protection, with a corrosion rate of 0.00045 mpy, compared to CDEA’s rate of 0.0009 mpy. Additionally, TEA demonstrated a higher inhibitor efficiency of 70.97%, while CDEA showed only 41.94%. These findings suggest that TEA is a more effective choice for preventing corrosion in API 5L Grade B steel, offering a viable solution to enhance the material’s durability in harsh environments.

Abstract

The electric current magnitude is a fundamental parameter that directly affects penetration characteristics and weld bead geometry. This study analyzes the effect of current variations on physical and mechanical properties in the cladding process using the Shielded Metal Arc Welding (SMAW) method. The materials used are low-carbon steel and HV-600 electrodes with a diameter of 3.2 mm. The SMAW method was applied with current variations of 100 A, 120 A, 140 A, and 160 A. The tests carried out were NDT liquid penetrant, macro structure, micro structure and Vickers hardness. The results indicate a positive correlation between increasing current and hardness values in the weld area, with the highest hardness recorded at 665.803 HVN at 160 A and the lowest at 515.143 HVN at 100 A. Meanwhile, in the Heat Affected Zone (HAZ), a non-linear pattern was observed, with a maximum hardness of 263.237 HVN at 120 A and a minimum of 219.110 HVN at 140 A. Microstructural analysis revealed the formation of ferrite, pearlite, bainite, and martensite phases in the weld area, providing insights into optimizing welding parameters to enhance the mechanical properties of low-carbon steel cladding.

Abstract

Corrosion in flowline pipes represents one of the critical challenges frequently encountered in the oil and gas industry, particularly within fluid transportation systems in the upstream sector. This issue significantly compromises material performance, incurs substantial economic losses, and poses serious occupational safety risks. Carbon steel, commonly used in flowline pipes, is highly susceptible to corrosion due to exposure to aggressive environments, including high humidity, formation water, and corrosive gases such as H₂S and CO₂. In line with the growing demands for infrastructure reliability and compliance with safety standards, effective corrosion mitigation has become increasingly urgent. The degradation of pipe integrity due to corrosion can jeopardize the long-term reliability of fluid transport systems, potentially leading to severe operational disruptions and escalating maintenance costs. This study aims to investigate the primary causes of corrosion and evaluate the effectiveness of applied mitigation strategies on flowline pipes at a production facility. The methods examined include the application of protective surface coatings and the use of wrapping systems to inhibit direct contact between the metal and corrosive agents. Additionally, pipe wall thickness measurements were conducted to estimate the remaining service life of the flowline system based on the extent of corrosion-induced degradation. The findings of this study are expected to offer technically sound and practically applicable recommendations for corrosion control, thereby enhancing operational reliability and contributing to the sustainable performance of oil and gas infrastructure.

Abstract

This research presents a Level 3 Fitness for Service (FFS) analysis, focusing on stress evaluation in the suction side of gas compressor piping in a gas-fired power plant in Indonesia, using the Finite Element Method (FEM). To expedite numerical calculations and reduce computational time, the analysis employs line elements within FEM, enabling efficient and timely assessment. The modeled operational conditions include sustained, expansion, and occasional seismic loads, providing a comprehensive view of pipeline behavior under various stress scenarios. The study results indicate that all pipeline segments analyzed show no potential for failure, with code ratios below 1. The sustained load has a code ratio of 0.71 with a maximum stress of 97.64 MPa, an expansion load of 0.66 with a maximum stress of 136.90 MPa, and an occasional seismic load, the highest at 0.70 with a maximum stress of 129.27 MPa. Among all loading scenarios, the compressor suction segment exhibits the highest code ratio, indicating the need for heightened attention in maintenance management. It is recommended that condition monitoring and inspection efforts be focused on this segment to prevent potential failure. The findings conclude that all code ratios from each loading scenario are acceptable, confirming that the pipeline segments meet the required safety standards. This reinforces the reliability of the pipeline system and validates the effectiveness of Level 3 FFS analysis in guiding maintenance strategies and risk management for critical gas pipeline systems.

Abstract

Non Destructive Test is a testing and analysis method carried out to evaluate and detect differences in characteristics or defects that arise in materials, components, structures or systems without causing damage to the part being tested. Liquid Penetrant Test is a Non-Destructive Test method using Liquid Penetrant containing Fluorescent by utilizing power capillarity which is the ability of the penetrant liquid to enter the gap discontinuity and developer work to lift the liquid back up which penetrates into cracks so that defects and corrosion can be detected. The purpose of this test is to determine discontinuities in the fabricated material by using 3 variations of penetrant temperature 5℃, 10℃ - 38℃, and 75℃ using 2 pieces of 7075 Aluminum material. Experiments carried out at normal temperatures (10℃-38℃) show clear indications of the material. while experiments using temperatures of 5℃ and 75℃ will make the indication on the material unclear (false indication) due to various factors such as viscosity, dwell time, penetration, developing.
