Type of metal hose

Company  Kohaflex for assembling of metal pressure hoses uses for most of applications pressure hoses in yardage type Parallel, Parallel K10, Parallel K20, Parallel 700 and type DUO. 


Hoses Parallel

are manufactured by roll bending of thin strips from stainless steel into thin-walled tubes, welded longitudinally by micro-plasma. Subsequently is on thin-walled tubes mechanically or hydraulically formed cold-parallel (toroidal) wave.


After that are corrugated hose braided with one or more layers of braid with wire from stainless steel, to increase the pressure resistance and mechanical protection. 







Hoses DUO

are manufactured by winding of profiled thin strips of stainless steel on helix and the resistance (seam) welding the circumference of the hose in place of transfers profiles.


After that are corrugated hose braided with one or more layers of wire braid from stainless steel to increase the pressure resistance and mechanical protection.





When selecting the type of hose it is necessary to base selection on maximal working pressure in conjunction with maximal working temperature.  If the operating temperature of the medium is above 100 ° C is necessary to use a type of hose which nominal pressure is greater , or equal to adjusted operating pressure (max. operating pressure / pressure coefficient k +).

Optimal hose length is calculated according to "Rules for the calculation" (see catalog). In particular, it is necessary to prevent twisting of hoses and wrap the ends.

Detailed design parameters of various types of hoses can be found in the catalog. For special application could be use special type of hose.
