* Unbraided Working Pressure given in table are one quarter of the pressure value, which will cause the hose to elongate and take a permanent set.
** Bursting Pressure apply to both Close and Normal pitch with Stainless steel braid, bursting pressure are given rather than working pressure to allow each Engineer to determine his own safety factor. The above table is to be considered only as a general guide, due to the commercial variation of tube gauges and manufacturing limitations.
Flexible Hose Assemblies
Flowflex Stainless Hose is corrugated from specially drawn thin wall tubing help to a micrometer tolerance throughout the entire length
FlowFlex Hose- Assemblies are available in sizes from 1/4 Inches to 8 Inches I.D. and in length
Flowflex Hose-Assemblies can be used at temperature from –196 degrees + 600degrees
Flowflex Hose-assemblies are pressure and vacuum tight and in smaller sizes the permissible operation pressure reaches 200 kg/cm2
Flowflex Hose-assemblies are used in chemical plants, paper plants, Tire moulds, Air-Conditioning plants, Textile machinery, steam-conveying lines, Gas-filling, Power houses, Oil Refineries
All Fittings and Flanges are supplied welded to the braided or unbraided hose. Secure further information by sending us your individual requirement.
Stainless and Mild Steel, may be specified as Rigid, floating and mild steel with stainless steel facing rings. |
