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.
