Through our intensive cooperation with the leading manufacturers of metallic flexible hoses Belman can deliver effective solutions across a wide range of applications.
Metallic flexible hoses are very flexible, they can absorb large movements and can be supplied with customised lengths to suit the installation. This gives great design freedom, enabling their installation in the most limited of spaces, where no other appropriate flexible solution could be used. Metallic flexible hoses are frequently deployed in situations where it is not operationally or economically viable to use expansion joints for the absorption of movement. Metallic flexible hoses are fitted to permit movements created by thermal changes in the system or mechanical influences such as vibrations from pumps or compressors installed with flexible mounts.
Metallic flexible hoses are manufactured as a convoluted tube and are usually fitted with a wire over braid. The convoluted core is produced from stainless steel or nickel alloy sheet with annular or spiral convolutions. For some applications the core can be produced as a multi-ply arrangement. The braid acts to support the core against pressure and also provides a restraint to prevent the expansion of the length of the core under positive internal pressure. For use in higher pressures environments multiple layers of braid are used to increase the pressure resistance of the metallic flexible hoses assembly.
