Abstract
Abstract A novel hose design for coupling steam generator sources to steam operated equipment and the like. The hose is provided with at least one layer of wire braid interspersed with flexible resilient layers to withstand high steam pressure. A seamless closed Fiberglas braid inner sleeve is provided in the bore of the hose to restrain rubber particles which may break away from the hose wall from entering the steamline so as to prevent foulup of delicate mechanisms coupled to the steam hose.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
205 words
For use in coupling a steam generating source to steam operated equipment, a relatively light weight flexible cylindrical shaped hose assembly for conveying steam at pressures in excess of 150 psi said hose assembly comprising: a seamless lightweight braided innser sleeve; a first seamless tubular layer of steam resistant resilient material surrounding said inner sleeve; a second seamless braided intermediate sleeve surrounding said first tubular layer and having braids formed of a plurality of wire strands collectively adapted to withstand the high pressures developed within the bore of the hose assembly and to enhance the ability of the hose assembly to retain its normal cylindrical shape; a second seamless steam heat resistant tubular cover layer formed of a resilient material and surrounding said intermediate sleeve; said inner sleeve being affixed to the inner surface of said first seamless tubular layer and defining the inner wall of the hose assembly, said inner sleeve comprising braided strands of steam and heat resistant glass yarn interlaced to form a closed woven sleeve exposed to the steam passing through the bore of the hose assembly for preventing particles which may break away from said first seamless tubular layer from entering into the flow of steam passing through said bore.
