Fig. 2. Types of maintenance

The choice of a corrective or systematic strategy, Fig. 2, is highly dependent on the incidence of failure and the ability to generate considerable losses in terms of shortfall and safety. This choice is made with a view to guaranteeing the quality of the pipes to be maintained by: • Improving production performance; • Improved reliability and increased probability of proper operation; • Availability assurance; • Ensuring maintainability by adopting optimal solutions. 2.2. Damage Model Modeling the damage of pipes in CPVC supports a multitude of experimental parameters Gugouch (2019) and Gugouch (2023). Fig. 4 illustrates the traction curves at different temperatures Merah (2003).
