After a section of the pipeline is taken out of service we clean it and inspect with a remote-controlled camera. The analysis of the video (or DVD) from the sewer inspection forms the basis to create a detailed computer report on the technical condition of the pipeline.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_custom_heading heading_semantic=&#8221;h3&#8243; text_size=&#8221;h3&#8243;]INSTALLATION[\/vc_custom_heading][vc_column_text]The first stage involves the preparation of a sufficiently long section of PE pipe for installation (by welding the required number of prefabricated sections) and placing such lining on installation rollers. The principle of SWAGELINING consists in temporary deformation of the lining by reducing its diameter which results in its elongation. The purpose of this is to make it easier to insert the prepared section of lining into the old pipeline.<br \/>\nDuring the process towing force is controlled all the time, preventing PE material from excessive stretching. Having completed the installation, towing force is removed from the earlier deformed pipe, and it returns to its original dimensions due to internal tension existing in the lining. This results in a tight-fit of the PE pipe to the walls of the rehabilitated pipeline, so called close-fit.<br \/>\n[\/vc_column_text][vc_custom_heading heading_semantic=&#8221;h3&#8243; text_size=&#8221;h3&#8243;]CONTROL[\/vc_custom_heading][vc_column_text]<strong>CCTV INSPECTION<\/strong><\/p>\n<p>Once the installation is finished and drains are opened a CCTV acceptance inspection is made and recorded on a DVD or another storage medium.
