Using pipe cracking, an existing pipe does not necessarily need to be replaced size for size, host pipes can be upsized to larger diameters to accommodate for increased use.
With pipe cracking a continuously welded pipe is pulled through an existing pipe not requiring any joints between pulling points, therefor there is minimal chance of leaks in comparison to open trench spigot and socket pipes.
Trenchless techniques are advantageous in several conditions, namely for pipelines..
– In developed areas where excavations must be kept to a minimum
– Under roads where traffic disruptions must be avoided
– Under surfaces which would require costly re-instatement
– In areas with heavily concentrated services
– Underneath permanent structures
– HDPE Butt Welding
– HDPE Electrofusion Welding
– Pipe Repairs and Replacement
HDPE (High Density Polyethylene) type of pipes has become prominent in the Civil Engineering industry recently. We found ourselves installing more and more HDPE over the last couple of years. As one knows, it is imperative to inspect each weld post welding on these types of pipes. It is with this in mind Nejeni Management decided to fully equip our CCTV Crew with all the equipment to not only do the inspections of welded HDPE pipes but also sewer pipeline inspections. To date, we have inspected and reported on in excess of 1000km pipelines.
Inspection Survey Reporting Software
WinCan is an easy-to-use reporting package that gives professional, clear and concise reports, which can be customised to your needs. Our technicians include photographs captured directly from the survey video footage and record short video clips to help provide as much information as possible.
WinCan also offers detailed analysis and reporting of defects and has the ability to do post-rehabilitation surveys.
NEJENI can offer “BEFORE” and “AFTER” photographs printed together as evidence that repairs have been carried out correctly.
Nejeni has emerged into the Civil Engineering playing field as a dynamic, reliable, innovative and quality focused company. Through the alignment with key role-players in the Civil environment, we have strategically gained knowledge and experience coupled with a raw desire at striving to deliver only best.
The slogan: “ensuring a better South Africa through the provision of quality workmanship” reflects the work ethics of the entire TEAM and has become the motto and vision of Nejeni.
