<p><em>Valve (valve) as one of the industrial products, is needed by companies engaged in controlling fluid flow for efficiency. This need is widely used by power companies and the oil and gas industry. The purpose of using valves is to limit and control liquids under high pressure conditions. One valve that is often used is the gate valve, which is a valve with a type of motion fully open and fully close. The demand for this gate valve requires a product with certain specifications to have a design with a good level of strength. In other words, a good valve product (valve), must have a good strength, safe and in accordance with the needs to be tested. This study aims to analyze the gate valve 2 9/16 WP 3,000 psi to ensure the valve produced is according to specifications, strong and resistant to fluid pressure. The method used is Finite Element Analysis (FEA) with the 2018 Solidworks software. The analysis is performed on the gate valve with a full open, full closed state and with gradual loading starting at 1,000 psi, 2,000 psi and 3,000 psi resulting from Computational Fluid Dynamics (CFD). The analysis was carried out at 300C, Based on the results of the analysis with FEA, it was stated that the gate valve 2 9/16 WP 3,000 psi was strong and safe to use. The safety factor value is significantly higher than the minimum permissible safety factor value.</em></p>

Three Dimensional Finite Element

Large diameter integral steel flanges are widely used in many applications in the oil and gas industry. The flanges of nominal pipe sizes, 26-inch and above with ring-joint gaskets as specified in ASME B 16.47 Standard, are used in the offshore applications for the transportation of oil and gas from production facilities. These pipelines require flanged connections at end terminations, mid-line tie-ins and expansion loops. The conventional design of large diameter steel flanges is based on one-dimensional analytical methods similar to the procedure in ASME VIII Boiler and Pressure Vessel Code, Division 1 Appendix 2. The effects of axial forces and bending moments are approximated by calculating an equivalent pressure. This usually results in conservative designs for the large flanges because it estimates the required stud pre-tension based on the assumption that the gasket will be unloaded entirely to a minimum stress, whereas only a small section of the gasket is subjected to low stress. This technical paper presents the quasi-static, nonlinear, and three-dimensional finite element models of large diameter steel flanged joint for the determination of stud pre-tension and change of stud tension under various loading conditions. The finite element analysis results are compared with the results obtained by using the equivalent pressure method and flange “Joint Diagram”.

Accurately predicting the burst strength is very important in the casing design for the oil and gas industry. In this paper, finite element analysis is performed for an infinitely long thick walled casing with geometrical imperfections subjected to internal pressure. A comparison with a series of full-scale experiments was conducted to verify the accuracy and reliability of the finite element analysis. Furthermore, three predictive equations were evaluated using the test data, and the Klever equation was concluded to give the most accurate prediction of burst strength. The finite element analysis was then extended to study the effects of major factors on the casing burst strength. Results showed that the initial eccentricity and material hardening parameter had important effects on the burst strength, while the effect of the initial ovality was small.

Casing design is one of the most important parts of the well planning in the oil and gas industry. Various factors affecting the casing material needs to be considered by the drilling engineers. Wells partaking in thermal oil recovery processes undergo extreme temperature variation and this induces high thermal stresses in the casings. Therefore, forecasting the material behavior and checking for failure mechanisms becomes highly important. This paper uses Finite Element Methods to analyze the behavior two of the frequently used materials for casing - J55 and L80 steels. Modeling the casing and application of boundary conditions are performed through Ansys Workbench. Effect of steam injection pressure and temperature on the materials is presented in this work, indicating the possibilities of failure during heating cycle. The change in diameter of the casing body due to axial restriction is also presented. This paper aims to draw special attention towards the casing design in high temperature conditions of the well.
