Thermoplastic pipes are utilized in all of the industrial fields for example water, sewage and gas piping systems and also other industrial applications, much like the transport of minerals and slurries. Choosing the HDPE pipe fittings depends on many criteria. First of all, it depends in the conditions of use of each and every kind of material. Secondly, all depends on the expense of the chosen material lastly the mastering in the material’s scenarios of failure.
The very last criteria are possible with the mastering from the material characteristics and the ability to detect the failure, burst or crack, before its occurrence. The adopted approach has to be proactive to facilitate the prediction from the failure and help the maintenance staff to apprehend the piping system’s damage on the right time. With this paper, we chose HDPE pipes as material for your study. Then, we leaded a new approach of failure analysis and prediction using new models. These models are obtained using a modified version of the stress controlled unified theory, a static damage model using burst pressures as well as a static damage model making use of the time to failure. For this reason, we used burst pressures of undamaged HDPE pipe fittings as opposed to ultimate stresses. Then, we created groove notches with different degrees of depth.
The obtained burst pressures from the pipes happen to be viewed as the residual burst pressures utilized in our damage models. The representation of your obtained data based on the life fraction gave us an idea regarding the critical life fraction and therefore the critical groove depth which is often allowed. This data continues to be confirmed by three damage models. Then, we determined the many stages of harm to help the predictive maintenance to define the safe intervals of the PEX-AL-PEX pipe. Moreover, three of the developed models, presented in this particular paper, represent a simplified approach to evaluate the damage according to static tests only, without doing any dynamic tests. The developed inexpensive approach could be a tool which can help the industrials to get 18dexkpky anticipative maintenance strategy and respect the security requirements. Also, it can help these people to do quick checks or launch audit pursuit to the manufacturers’ factories for HDPE pipes’ quality control and conformity check with regards to the codes.
