Fire engineering flexible hose with roll grooved
Roll grooved flexible hose is a corrugated stainless steel hose with external stainless steel braided mesh. It is commonly used in high temperature or highly corrosive applications where a rubber hose is not suitable. It is also popular in permanent piping installations and short lengths (jumper) in potable water, cooling, steam, or other liquid applications where a rubber hose does not provide enough flexibility or a long enough service life (rubber and plastics will degrade when subject to the elements). Our standard is the SS304 or SS316 tube with the SS304 single braided reinforcement (also available in double braided mesh cover). The braided mesh acts as a reinforcement to increase pressure ratings and prevent elongation - it is not designed to withstand dragging or abuse. It is also available with no reinforcement for vacuum or drain lines. In order to reduce the chance of failure, flexible metal hose cannot be "twisted / torqued" or flexed on more than one plane - special care must be used during installation.
Roll grooved flexible hose are made of annular corrugated 304 stainless steel tube covered by a tightly woven 304 stainless steel braided mesh for long lasting durability, the corrugations are very close pitched for maximum flexibility. Roll grooved flexible hose assembly has carbon steel grooved fittings on each end to provide optimum performance, flexible hose reduce pipe wall noise transmission, prevent pipe fatigue, simplify alignment problems and reduce equipment flange stress available in a variety of dimensions. Also, when flow velocity exceeds a certain value, resonant vibration can occur in hose and lead to premature failure (increasing the hose diameter or use of a liner can combat this problem). If vibration is severe, contact us for application information.
