flexible metal hose annular

Flexible Metal Hose >> Annular corrugated pipe

 

Stainless steel braids added to corrugated metal hoses significantly improve the pressure that the hose can withstand. 
High pressure flexible hose are usually single or double braided for higher pressure capabilities. Its corrugated bore
can be T321 in annular construction, while the braided layers use 304. Standard pitch (close pitch) is designed for great flexibility.

High pressure braided hoses are capable of withstanding extraordinarily high temperature and pressure applications,
such as hydraulic systems.
