Drain Lining Foundation Course – TubeGun

In 2006, ER Technical created a drain lining course. We have modified this course into what it is now. A foundation training course for Cured-in-Place Pipe (CIPP) using the Tube gun inversion method.

This course is ideal for a new starter to lining and/or someone new to using the inversion method using a tube gun. The course is held at our Chester depot and is 50/50 Theory/practical.

Course Content

  • Drain lining methods and equipment
  • Health & Safety considerations
  • CIPP lining overview
  • Liner construction
  • Resin types and impregnation
  • Types of cures
  • Setting up the TubeGun
  • Installing an inversion liner
  • Best practice during liner installation

    Tubegun Pocketjet is a handheld inversion unit that easily installs liners with dimensions 50-150mm, up to 5mm thickness. With a simple press of the trigger, the liner is inverted into the pipe. Tubegun Pocketjet is primarily intended for shorter installations up to approx. 15 meters, but longer distances are possible. Tubegun Pocketjet is delivered complete with inversion nozzles for DN50, DN75, DN100 and DN150mm.

    Re-Tec are proud to be the exclusive dealer for the Tube Gun pocket Jet in the UK. We are encouraged by the unprecedented amount of enquiries we have received, that this leap innovation will be a great success.

    If you are interested, we are taking orders online.

I went on the tube gun lining course which I would recommend anyone that buys the system should go on. Paul was very clear when explaining how the system worked & even went out of, he's way to put the course on for me separately which I appreciate. I also picked up some tips while I was there which was very useful. I will definitely be buying more materials from Re-Tec in the future. Once again thank you.
