PE 100 pipes are produced according to their diameters and pressure classes as straight tube or tube coil. PE pipes can be rotated
360 without using pipe bend depending on mechanical features of its raw material.

Because of this feature coil diameters can be 18-35 times more than pipe diameter. Top connection number is decreasing in tube coil pipes.
Projects are completed fast by instalment speed. The costs of instalment, labour, shipping and storage are decreasing.
Due to the
