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

FCAW is a semi-automatic welding method that offers advantages in welding speed, weld quality, and flexibility in various welding positions. The process begins with equipment preparation, selecting welding parameters according to the Welding Procedure Specification (WPS) standard, and then carrying out welding using root pass, fill pass, and cap pass techniques. Evaluation of welding results is carried out through visual inspection and non-destructive testing (NDT), such as Magnetic Particle Inspection (MPI) and Ultrasonic Thickness Testing (UT) to ensure the quality and integrity of the joint. The results show that the FCAW method is highly effective in supply boat fabrication, especially when supported by good work procedures, adequate operator skills, and strict quality control. This research is expected to provide a practical overview and serve as a reference for students and industry in implementing welding technology in the shipping sector.

Abstract

This paper presents an experimental analysis of resonance behavior in a mechanical vibrating beam. A cantilever beam made of aluminum was subjected to forced vibrations using a shaker, and the frequency response was measured with an accelerometer. Resonance frequencies for the first three modes were determined and compared with theoretical predictions based on Euler-Bernoulli beam theory. The experimental results showed excellent agreement with theoretical values, with errors less than 1%, validating the approach. This study underscores the importance of understanding resonance in mechanical structures to prevent failures due to excessive vibrations.

Abstract

The welding process is a metal joining method that utilizes high heat energy, which can trigger changes in the microstructure, deformation, and the emergence of residual stress in the area around the joint. This study aims to examine the impact of variations in heat input in the Submerged Arc Welding (SAW) process on the microstructure and toughness of SM 490 steel, especially in the weld area and heat-affected zone (HAZ). The SAW method was chosen because it has high efficiency, is easy to automate, and is able to produce good quality joints. This study used three levels of heat input, namely 2.1 kJ/mm, 3.16 kJ/mm, and 4.3 kJ/mm. Based on the test results, increasing heat input causes slower cooling, which affects the formation of microstructures such as ferrite at the grain boundary, acicular ferrite, Widmanstätten ferrite, bainite, and martensite. Acicular ferrite with fine size and interlocking pattern is known to contribute to increasing the toughness of welded joints. The maximum toughness in the weld zone, amounting to 117 Joules, was achieved at a heat input of 3.16 kJ/mm with a test temperature of 0°C. Meanwhile, the best toughness value in the HAZ of 17.5 Joules was recorded at a heat input of 2.1 kJ/mm at a temperature of -20°C. The results of this study confirm that appropriate heat input settings are very important to obtain optimal microstructure and toughness in welding SM 490 steel using the SAW method

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.

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.
