LT583 EN856-4SP 4 Wire Spiral Hydraulic Rubber Hose
A. Regarding the hose and fittings assembly shall consider the following aspects;
Working environment; environment temperature, weather condition and other external contact objects.
Conveying medium: liquid, gas, paste, powder, or mixture of several media;
Medium transmission mode: positive pressure transmission, negative pressure suction;
Working conditions: pressure, temperature and flow of conveying medium; Pulse or motion frequency; Chemical properties of the medium;
B. Hoses and hose assemblies have limited service life. Factors leading to reduced service life include:
The bending radius of the hose installation is too small, and the hose body is torsional deformation;
Hose installation free length or movement length is not enough, squeezed, rubbed, stretched and twisted by external forces;
The working temperature or pressure of the hose exceeds the designed working temperature or design working pressure;
The hose connection does not meet the standard, and the quality of the buckle is unqualified;
Poor operating conditions, hose outer rubber layer is polluted and corroded (such as spraying paint), mechanical damage, etc.;
