Many different fitting designs may be attached to the hose assembly. Selection of the proper material for the end fittings must be considered. Fitting materials such as carbon steel, malleable iron, stainless steel, bronze or brass may or may not be the same as the hose assembly material. Correct attachment of the fittings is essential to the integrity of the assembly.
DO NOT COMPRESS
OR EXTEND AXIALLY.
Corrugated metal hose installed in-line with the longitudinal axis of the piping should not be subjected to axial movement.
DO NOT TORQUE
Metal hose assemblies should not be used to compensate for bolt hole misalignment. Floating flanges will help to minimize twisting of the metal hose. Pipe unions will help to reduce twisting during connection to the piping. The use of two wrenches will help to keep the hose from twisting when tightening the pipe union.
DO NOT ALLOW HOSE MOVEMENT
IN MULTIPLE PLANES.
Flexing a metal hose in two separate planes of movement will torque the hose assembly. Always install the metal hose assembly so that flexing occurs in one plane only and this is the same plane in which bending occurs.
AVOID SHARP BENDS.
Use elbows to avoid severe bends near the end of the metal hose assembly.
CENTERLINE BEND RADIUS.
The minimum centerline bend radius for dynamic flexing should never be less than the values in the product specification tables.
