Studying the Effect of Corrosive Liquids on Pipes Properties of Unplastizied Polyvinyl Chloride (UPVC) Which is Used in Sewage Purpose

Abstract

The current study concerns with studying some mechanical and physical properties of different samples taken from Unplasticized Polyvinyl Chloride (UPVC) pipes used in sewage purpose. Impact strength, compressive strength, shore-D hardness, and diffusion coefficient also were calculated for the samples immersed in different solutions (Wastewater, HCl-0.5N, and Tape water) for four months. Results showed that the mechanical properties of samples were affected by solutions and reduced by (3 – 5)% for impact strength and (10%) for compressive strength. Values for diffusion coefficient (D) were calculated, it was found that (HCl-0.5N) had a higher value, followed by wastewater then tape water. No cracks were observed, and there were no changes in sample’s dimensions after immersion in solutions.
