Mandals Tube In is developed for renovation of leaking drinking water mains. It is a strong circular woven hose extruded with a flexible polyethylene material (PE). The weave is made from high tenacity filament polyester yarn and is covered inside and outside by the “extrusion through the weave” production method, giving an outstanding adhesion level to the PE-material as well as being firmly encapsulated.
|
The hose is packed in a “U-shape”, which in combination with high flexibility allow easy installation into the host pipe by pulling, even through sharp bends. No steaming is needed to inflate the hose afterwards. By recoupling and just setting the installed hose under normal water pressure, it opens up and expands towards the inner host pipe wall. Special end couplings are available on request.
Mandals Tube In is a semi-structural, stand-alone hose which will ensure continual water supply even if the host pipe should break.
Prior to installation all that is needed is a regular cleaning procedure of the host pipe by Polly Pig or other cleaning method.
The easy installation and short down period of the water supply make the Tube In a unique renovation system for drinking water mains.
Standard length is 200 meters. Longer lengths can be made on request.
