Abstract

Ensuring the structural integrity of casing heads under high-pressure conditions is crucial in oil and gas well safety. This study applies Finite Element Analysis (FEA) using Solid-Works 2024 to evaluate a 13-5/8 5K × 13-3/8 5K casing head design under hydrostatic pressure up to 7,500 psi, following API 6A standards. Unlike conventional designs that rely on a single material, this research compares AISI 4130 alloy steel and Stainless Steel 410 to assess their structural performance and interchangeability. The simulation analyzed stress distribution and deformation, revealing both materials stayed well within safe limits, with a maximum Von Mises stress of 18,196 psi and deformation of 0.00006112 inch. The results demonstrate that material substitution is structurally viable, offering a cost-effective and supply-chain-resilient solution. The novelty lies in validating design adequacy through simulation of the weaker material, confirming its suitability for both. This method enhances design flexibility and material selection strategies for pressure-containing components.

Abstract

The use of cladding methods in manufacturing corrosion-resistant pipes is crucial for industries such as oil and gas, chemical plants, and pressure vessel manufacturing. This study focuses on ASTM B424 UNS N08825, a corrosion-resistant alloy (CRA) to be used as the surface layer for steel pipes. The cladding method involves forming CRA sheets into longitudinal pipes, followed by welding the joints, annealing, and rapid cooling before high process expansion to surface layer the steel pipes. At a temperature of 930-990°C, the annealing process aims to reduce stress and improve material properties, followed by rapid cooling to stabilize the microstructure. Various tests were conducted on the CRA liner pipes with or without annealing and quenching, including tensile testing, hardness testing, chemical composition analysis, and microstructure examination. The results showed that the material's ultimate tensile strength and hardness significantly increased after the treatment, with better uniformity in the microstructure. This study concludes that annealing and rapid cooling enhance the mechanical properties and stability of ASTM B424 UNS N08825, allowing the cladding process on steel pipe surfaces to be performed flawlessly and making it suitable for high-performance applications in corrosive environments.

Abstract

This study examines the mechanical and microstructural behavior of API 5L X65QS/QO PSL2 seamless carbon steel pipes subjected to a hot induction bending process followed by quenching and tempering. The research aimed to evaluate the combined effect of mechanical deformation and heat treatment on the material’s strength, hardness, and toughness. Experimental procedures were performed on a 12-inch seamless pipe bent at 900 ± 15 °C, quenched in agitated water at 15 °C, and tempered at 660 ± 15 °C. Mechanical testing revealed that the Ultimate Tensile Strength (UTS) and Yield Strength (YS) increased by approximately 8.5%, while hardness decreased slightly from 215 HV to 210 HV. Elongation improved from 29% to 32%, indicating enhanced ductility. Microstructural analysis showed a fine ferrite–pearlite structure with an ASTM grain size number greater than 8, confirming effective grain refinement achieved through controlled heat treatment. Overall, the combined hot induction bending, quenching, and tempering processes successfully produced a fine-grained material with improved strength, ductility, and toughness, demonstrating its suitability for high-performance and high-pressure pipeline applications.

Abstract

This study investigates the mechanical and macro structural performance of welded joints produced by Flux-Cored Arc Welding (FCAW) and Gas Tungsten Arc Welding (GTAW) on API 5L Grade B low-carbon steel pipes used in marine CO2 fire suppression systems. The experimental work involved tensile, bending, hardness, and macro structural tests to evaluate the influence of each welding process on joint integrity. Both FCAW and GTAW joints exhibited high mechanical strength, with ultimate tensile strengths of 506MPa and 516MPa, respectively, exceeding the minimum requirement for API 5L Grade B steel. Fracture occurred in the base metal rather than the weld zone, confirming the superior strength and sound fusion quality of the joints. GTAW demonstrated slightly higher tensile performance and cleaner weld morphology due to the controlled heat input and stable arc achieved with 100% argon shielding, whereas FCAW produced marginally higher hardness in the heat-affected zone due to CO?-induced cooling effects. Macro structural analysis revealed complete penetration and the absence of porosity, slag inclusions, or cracks in both processes. The results comply with AWS D1.1 and ASME Section IX standards, confirming that both welding methods or their hybrid application are suitable for producing safe, reliable, and regulation-compliant marine fire suppression pipelines.

Abstract

Improving energy efficiency and temperature stability in freezer systems is a critical issue due to high energy consumption and thermal fluctuations that can degrade the quality of frozen products. Previous research has generally focused on compressor optimization and active refrigeration systems, while the use of Phase Change Materials (PCMs) as passive energy storage media in small-scale freezers is still limited. This study aims to analyze the effect of adding PCMs on the cooling load and thermal performance of the freezer. The methods used include designing a three-layer wall model (aluminum–polyurethane–PCM), calculating conduction energy, sensible heat, and latent heat, and comparing seven types of PCMs using an analytical approach and CoolTools-based thermal simulation. The results show that dry ice gel provides the best performance with the lowest total cooling load of 29.02 W and latent heat of 5.40 × 10⁵ J/kg. The system has a COP of 2.36 with a thermodynamic efficiency of 53.74%. PCM integration has been proven to reduce temperature fluctuations and reduce system workload, thus contributing scientifically to the development of energy-efficient freezer designs based on passive thermal energy storage.

Abstract

Gears are essential components in mechanical transmission systems, responsible for transferring power between shafts in various types of machinery. The strength of gears plays a critical role in the efficiency and reliability of these systems, as improper load handling can lead to material failure or gear damage. This study aims to analyze the strength of gears by considering several factors such as material properties, geometry, and operational conditions. The materials tested in this research include carbon steel SAE 1045, alloy steel SAE 4140, and stainless steel (SS 304), all of which are commonly used in gear applications. The gear geometry analyzed includes variations in module (2 mm and 3 mm), the number of teeth (20 teeth), and the pressure angle (20 degrees). The research methodology includes Finite Element Analysis (FEA) to simulate stress distribution on gears under both dynamic and static loading conditions, along with experimental testing to validate the simulation results. The results show that SAE 4140 alloy steel exhibits superior tensile strength and wear resistance compared to SAE 1045 carbon steel, though at a higher cost. Stainless steel (SS 304) offers excellent corrosion resistance but lower tensile strength, making it less suitable for high-load applications. Additionally, increasing the gear size (3 mm module) reduces stress on the teeth but increases the overall size and weight of the gear. This study provides important insights into material selection and gear design, helping to improve the strength and durability of mechanical transmission systems.

Abstract

Thermal performance of mold plays a critical role in determining the quality and productivity of aluminium casting products, including fishing sinkers. Improper temperature distribution within the mold can lead to casting defects, uneven solidification, and extended cooling time. This study focuses on the thermal optimization of an aluminium fishing sinker mold through the design and improvement of cooling channel configurations. Numerical simulations based on heat transfer analysis are conducted to evaluate temperature distribution, cooling efficiency, and solidification behavior within the mold. Several cooling channel designs are analyzed and compared to identify the most effective configuration for achieving uniform temperature distribution and enhanced heat dissipation. The results show that optimized cooling channel design significantly reduces temperature gradients, shortens cooling time, and improves overall casting quality. This study demonstrates that thermal optimization through proper cooling channel design is an effective approach to enhancing the performance and reliability of aluminium fishing sinker molds.

Abstract

This study discusses the performance of the liquid cooling system on the Honda Vario 125 motorcycle to understand its effect on the thermal efficiency of the engine during operation. The liquid cooling system plays a role in keeping the engine temperature stable, so that the combustion process takes place more effectively. The test was carried out by taking data on cylinder head temperature, coolant temperature, and fuel consumption at various engine rev levels. The data obtained is analyzed to assess the ability of the cooling system to reduce temperature rise and keep the engine at an optimal working range. The results show that at medium to high cycles, liquid cooling systems are able to maintain temperature stability with relatively small fluctuations. These more stable thermal conditions contribute to improved combustion efficiency which is reflected in decreased specific fuel consumption and increased thermal efficiency. These findings indicate that the cooling system design on the Honda Vario 125 has adequate capabilities to maintain consistent engine performance, especially in daily use with load variations. This study can be a technical reference in the development of motor vehicle cooling systems.

Abstract

This study aims to evaluate the effect of shielding gas types, namely carbon dioxide (CO₂) and argon, on the quality of welded joints in the Gas Metal Arc Welding (GMAW) process with low carbon steel as the base material. The research method was carried out experimentally using a steel plate measuring 150 mm × 75 mm × 6 mm and an ER70S-6 electrode wire with a diameter of 1.0 mm. The welding process was carried out with an inverter-type GMAW machine using fixed parameters: 120 ampere current, 22 volt voltage, 4 mm/s welding speed, 12 mm stick-out distance, and 15 liters per minute shielding gas flow rate. The specimens were divided into two groups based on the shielding gas, namely pure CO₂ and pure argon. Evaluation of the joint quality was carried out through tensile tests, Vickers hardness tests on three main zones (weld metal, heat affected zone, and base metal), as well as microstructure and visual observations. The results showed that the specimens with argon gas had a higher average tensile strength (460 MPa) than CO₂ (420 MPa). The hardness values were also higher and more even in the argon specimens, with a finer and more uniform microstructure. In conclusion, the use of argon produces welds with better mechanical and metallurgical qualities than CO₂. Therefore, argon is more recommended for welding low carbon steels that require high strength and precision.
