Hydraulic hose in use and design should note the following

reusable hydraulic hose fittings in use and design should note the following:
1, the bending radius of hydraulic hoses should not be too small, usually not less than the value "of hydraulic hose assemblies technical features" in the regulations. Connection hose assembly and fittings should have a straight part, this length should not be less than twice the pipe diameter.
2, hydraulic hose assembly should take into account the length of the hose after a pass into the pressure oil, the length of the shrinkage will occur, the general shrinkage of 3 to 4 percent of the tube length. Therefore, when hose assembly installation, not allowed to be in tension.
3, metric hydraulic hose fittings assemblies should be installed to ensure that does not happen torsional deformation. Hose joint axis should be placed in the plane of movement, to avoid each other at both ends of the hose impaired movement.
4, hydraulic hose should avoid contact with the sharp parts on mechanical and friction, so as not to damage the pipe.
