PU lined wear resistant reducer pipe Features: 1, Anti-fouling: polyurethane elastomer surface is smooth, non-polar, non-hydrolyzable. It can prevent the adhesion of fouling layer, with outstanding anti-fouling 2, Good wear resistance: polyurethane elastomer has excellent wear resistance, abrasion value test results are usually in the 0.03-0.2mm3 / m range, which is about 3-5 times of the natural rubber. 3, Corrosion resistant performance: polyurethane elastomer corrosion resistance of acid, alkali, salt and water and other media 4, Low temperature performance, to adapt to wide temperature range: polyurethane elastomer has good low temperature performance, mainly in the brittle temperature is very low (-50 ℃ ~ 70 ℃) suitable for -50 ℃ ~ +100 ℃ temperature range of media applications.
