Technology:
Static cracking
In 2007 the company, by contract for the Lower Silesian Machine Factoru ZANAM-LEGMET LTD. in Polkowice, has replaced the sanitary pipeline DN 200. This task was achieved by way of the static cracking method. Works consisted of inserting the PE pipeline in to the existing, obstructed sewage system made of concrete and stoneware pipelines laying at 3 to 4.5 meters without an open dig. The above method was used because of the depth, at which the pipeline lay, the harsh water and ground conditions, close proximity to housing and preexisting non-registered underground infrastructure devices.
