The pipe reinforced with bandages in a polyethylene mantle is a special variant of production of a preinsulated pipe in a polyethylene bandage for underground trenchless pipe laying. It is used in laying at the site with high load on the surface of PUF pipe-line – under automobile roads and similar infrastructure. Such pipes are laid in steel protective casings of larger outer diameter which give additional protection from pressure of ground and transport.
