Composites tubes MANUFLEX®
Manuflex® tubes are comprised of an NBR nitrile rubber inner tube, a single galvanised steel braid and an outer cover in translucent flexible PVC.
The inner tube is obtained by extrusion.
It is then braided in a horizontal braider and passes through an angle head extruder which applies the outer cover in translucent polyvinyl chloride to protect the steel braid from external aggression.
Manuflex® tubes are :
- Very robust with regards to impacts.
- Highly polyvalent.
- Very flexible.
- Easy to maintain.
Very flexible, Manuflex® tube is highly safe for everday use. its burst pressure is very high and its translucent PVC outer cover, whilst protecting the steel braid, allows users to check the condition of same.
It is for this reason that this is used as a multipurpose hose in the chemical industry.
Admissible working temperatures of Manuflex® tubes range from 0°C to +60°C.
Marking of manuflex tubes is as follows : tecalemit flexibles - part N° - manuflex - ID - batch N°
|Table of Manuflex® working pressure ratios with regards to working temperatures|
|T(°C)||0° to +20°||30°||40°||50°||60°|
The values of working pressure ratios according to working temperatures indicated above represent only the average of the results obtained from burst pressures divided by a safety factor, given that these are variable according to tube diameter and wall thickness.
