Product Advantages
l Heading, laying down and connecting the HDPE Silicon Duct can be performed under ambient temperatures of -20°C to +50°C.
l If temperature drops below -20°C, the HDPE duct get brittle so that their breaking can occur if they are stressed, above all by impacts. Neither damage nor deterioration of the mechanical properties of the HDPE duct occurs during storage of the pipe without handing under lower temperatures usual in our climatic conditions (up to -30°C).
l Minimum bending radius for pipe’s dimensions must not be exceeded. This is 20 times value of their outer diameter.

Packing Information
l Standard length of the coil is 2000m (2KM).
l The HDPE Silicon Duct shall be coiled to the removable steel pan directly. The outer silicon duct shall be covered with light-tight plastic film.
l Both ends of the HDPE Silicon Duct shall be sealed with the plastic cap to prevent the entry of moisture during shipping, handling and storage.
