Claims (1)
- Части покрытий из пластмассового материала на металлических трубах, которые были либо сняты, либо повреждены, ремонтируют с использованием одного или более сегментов полого цилиндра, имеющего внутренний радиус, равный внешнему радиусу металлической трубы, и внешний радиус, равный сумме внешнего радиуса металлической трубы плюс длина от 80 до 120 % толщины покрытия. Сегмент полого цилиндра изготовляют из полимерной композиции, предпочтительно вспененной, содержащей 92-98 мас.% термопластичного полимера, выбранного из полипропилена кристаллических сополимеров пропилена, содержащих от 2 до 25 мол. % этилена и/или альфа-олефина с 4-10 атомами углерода гетерофазные композиции, содержащие этот пропилен или кристаллические сополимеры пропилена в комбинации с одним или более эластомерными олефиновыми сополимерами; 2-8 мас.% наполнителя, имеющего задачу блокирования ультрафиолетового излучения.
