Calculating the Optimum Angle of Filament-Wound Pipes in Natural Gas Transmission Pipelines Using Approximation Methods

Abstract

Given the increasing use of composite materials in various industries, oil and gas industry also requires that more attention should be paid to these materials. Furthermore, due to variation in choice of materials, the materials needed for the mechanical strength, resistance in critical situations such as fire, costs and other priorities of the analysis carried out on them and the most optimal for achieving certain goals, are introduced. In this study, we will try to introduce appropriate choice for use in the natural gas transmission composite pipelines. Following a 4-layered filament-wound (FW) composite pipe will consider an offer our analyses under internal pressure. The analyses' results will be calculated for different combinations of angles 15 deg, 30 deg, 45 deg, 55 deg, 60 deg, 75 deg, and 80 deg. Finally, we will compare the calculated values and the optimal angle will be gained by using the Approximation methods. It is explained that this layering is as the symmetrical.

Static and Dynamic Mechanical Properties of 3D Printed ABS as a Function of Raster Angle

“…The resulting pattern can be presented by a regular diamond-shaped cell with a simple laminated +ϕ/−ϕ fiber orientation [9]. In the case of these materials, a winding angle of 55 • (see Figure 1) provides the best mechanical performance, especially considering ring stiffness of the material, very important from a technological point of view [10,11]. In comparison to conventional manufacturing processes used for thermoplastic materials, FDM printing creates near-net-shape components with over 90% material usage.…”

The main goal of the presented research work is to analyze the influence of fill angle on tensile properties of 3D printed samples, as well as noticeably less frequently analyzed, impact performance and dynamic mechanical behavior to optimize further manufacturing processes [12].…”
