High temperature resistance: the maximum sustained working temperature is up to 70 degrees, the maximum transient temperature is up to 95 degreesHeat preservation: low thermal conductivity result in preserving heatNon-toxic: no heavy metal additives, not be covered with dirt, not be contaminated by bacteriumLower installation costs: light weight and ease of installation can reduce installation costsHigher flow capacity: smooth interior walls result in low pressure loss and high volume 90°Elbow  (Soc)Spec(mm)Suttle(gram)PCS/OPPL2016.23400L25262000L32451000L4076600L50128360L63253200L75467100L90634    80L1101200    40L1102300    40
