Ventilation hoses made of PVC are used in mines, tunnels and workplaces with explosion risk.
Temporary party and event tents must also be heated and ventilated. Just like the tents, the laid heating pipes are not made of metal, but with flexible vinyl material. The hoses can be made in any length and diameter. They can also be used for heating or for drying buildings. When they are not needed, they can be folded and stored in a space-saving manner.
With the corresponding Leister welding machine, the hoses can be pre-fabricated before the so-called liners are inserted into the existing pipes. This procedure is more cost-effective, does not interfere with the environment as much as other rehabilitation methods and is suitable for repairing aging pipes.
