Abstract
The paper analyzed the chemical resistance of polyethylene (PE) pipes, some attention paid to the general phenomenon of degradation which influences polyethylene life. The influence of synthetic condensate (50% (by mass) n-decane and 50% (by mass) 1-3-5 trimethylbenzene) about the strength and durability of polyethylene pipes was established . Keywords: polyethilene pipe, chemical resistance, strength, durability.
