Investigation of the design parameters affecting the safety factor in fittings by using Taguchi method

Abstract

Introduction. In Turkey, it has been observed that unqualified Chinese fittings are used in water and natural gas connections. Domestic production industry of cast iron did not remain competitive. It is thought that due to the production of aluminum pipe fasteners and corrosion resistance, production easiness and low cost, it can be preferred. Material and methods.For the design of aluminum tee pipe fittings, the authors have proposed a new design. This design incorporates angled inner surface and bracelet design with some standard measurements. In this study, the parameters forming the new type design are determined. Design parameters and their levels are specified. Pressure endurance analysis was performed by using the finite element method. The Taguchi method was used to reduce the number of experiments and to investigate of optimum conditions of the effects of the parameters on the pressure balance. Results. The results of compressive strength analysis were listed by using the ANSYS program. Variations in weight, elastic deflection amount, vertical and horizontal axis maximum stress amounts were analyzed by Taguchi method andvariance analysis. The percent effect ratios of the design parameters were investigated. Conclusions. With this work, it is desired to optimize in design and production. Minimum weight and maximum safety coefficient are desired. Although the weight is not much, the parameter values that increase the strength were determined.
