Structural Feasibility Study on the Slidable One-Touch Extension Fitting for Plastics Pipes with Virtual Assembly and Experiments
Structural feasibility study on a Slidable One-Touch Extension (SOTE) fitting for profilewalled drainage and sewer pipes was performed. SOTE fitting was developed for the purpose of accommodating large thermal deformation that could occur during installation, which if not treated properly in design can cause problems such as loosening of the pipe and in some cases cracking of the support constraint. SOTE fitting assembly process was examined via virtual assembly to determine the structural soundness and thermal deformation behavior was investigated for its design efficiency and performance. For both analyses the finite-element method was utilized and corresponding experiments were also performed to support the findings. Finally, cyclic fatigue tests were carried out on fittings followed by the leak proof test to determine integrity of the SOTE fittings. Through analysis and experiments SOTE fitting was shown to perform its designed functions with required structural stability.
