Полипропиленовые трубы. Технические характеристики

Основные физико-механические параметры PPR труб, подтвержденные российскими стандартами (ГОСТ):

  • температура плавления: +149С (ГОСТ21553);
  • плотность: 0,9 г/куб. см (ГОСТ15139);
  • предел текучести (растяжение): от 24-х до 25-ти Н/кВ. мм (ГОСТ11262);
  • предел прочности на разрыв: от 34-х до 35-ти Н/кВ. мм (ГОСТ11262);
  • удлинение по достижении предела текучести: 50%;
  • коэффициент расширения полипропиленовых труб: 0,15 мм/ммС (ГОСТ15173);
  • теплопроводность (при +20С): 0,24 Вт/мС (DIN 52612);
  • удельная теплоемкость (+20С): 2 кДж/кгС (ГОСТ23630).
