METHOD FOR MANUFACTURE OF FIRE RESISTANT HOSE ARMOURED WITH METAL BRAIDING Russian patent published in 2009 - IPC F16L11/00 

FIELD: technological processes.

SUBSTANCE: in method for manufacture of fire resistant hose armoured with metal braiding by means of coaxial fire resistant layer on it from siliceous textile soaked with solution of organosilicic rubber and polymerised to rubber-like condition, layer of siliceous textile in process sequence is applied between layers of metal braiding, afterwards it is soaked by hose submersion with plugged ends in solution of organosilicic rubber and polymerised, at that solution of organosilicic rubber used is solution of 100 mass parts of low molecular organosilicic rubber paste in 50 mass parts of benzene, and duration of soaking is assigned as 10 minutes.

EFFECT: higher efficiency of fire protection of fire resistant hose armored with metal braiding.
