The hose has excellent leakproofness, high flexibility and resistance against:

• elastic expansion;
  

• traction;
  

• flection;
  

• abrasion;
  

• blows,
  

• vibrations, owing to pitch of helical formation;
  

• high temperatures up to +600 °C 

APPLICATION:
It is used for tubing of old and new chimneys in single and multistory buildings where solid, liquid and gaseous combustibles are used for heating.
The old and new chimneys made of porous materials (bricks, argile tubes, ceramics etc) do not offer necessary guarantee for normal and long-lived exhausting of burning products.
The fissures and suspected joints in these chimneys can provoke:

• polluting of rooms by toxic gas infiltration,

• damaging the inside walls by infiltration of corrosive liquids which result from condensation of buring products and

• dissipation of energy.

The classic chimneys are not adapted to technical conditions and possibilities of all heating units with several heating elements.
Installation of flexible tube in old or new chimneys offers the following advantages:

• considerable reduction of flow resistances;

• improvement of draft;

• perfect corrosion resistance;

• perfect protection of penetration of burning products and their compounds trough house facades,

• considerable reduction of condensation;

• avoidance of soot sedimentationit eliminates fire possibility and

• exact adjusting of chimney diameter and heating unit power
