HOSE FOR CONNECTING TO GLASS BURNER AND METHOD FOR SUPPLYING RAW MATERIAL GAS USING THE HOSE

摘要

PURPOSE:To provide a glass-burner connection hose effective in preventing the condensation of raw material gas, improving the safety and facilitating the setting of a glass burner, and to provide a method for supplying raw material gas using the hose. CONSTITUTION:The objective glass-burner connection hose has a double-layer structure consisting of an inner tube 10 for passing a raw material gas, having bending flexibility and essentially resistant to the expansion in radial direction and an outer tube 11 having bending flexibility, essentially resistant to the constriction in radial direction and surrounding the inner tube to form a heat- insulation vacuum space around the inner tube. A raw material gas is supplied through the hose.
