The use of cosmetic plastic hose environment and maintenance methods

The use environment of cosmetic plastic hose and maintenance method of cosmetic plastic hose should be managed carefully, don't drag on sharp or abrasive surface, bending or flatten, for example, don't let the wheels rolling on the hose. Can you list some are below the influencing factors of cosmetic tube service life. Pressure filling hose products should not exceed the prescribed design work pressure. Temperature of cosmetic plastic hose goods should not be prescribed by the hose manufacturer, or use the recommended temperature range. Environmental cosmetic plastic hose cannot be used beyond the design requirements of environment. As to its applicability in doubt, or need to use in a special or under different conditions, the hose manufacturer shall be consulted. Plastic hose bending radius cannot be set by the hose manufacturer or recommend the bending radius of the following is used, otherwise the delivery of materials will be limited. Should avoid near the hose joint bending or torsion, because in these locations continuous bending causes hose fatigue damage increased, resulted in hose premature failure torsional stress cosmetic plastic hose usually are not suitable for working under distortions. Tensile stress only in the case of special design, hose can withstand tensile stress. If you have any doubt, the applicability of the hose can ask hose manufacturer. Vibration can make the hose vibration fatigue fever, especially near the joint, can lead to premature failure hose assembly. Understand the design and production of the hose from hose manufacturer whether can withstand the vibration. End pipe before installation at the end of pipe fittings, check whether the fitting and hose is match, the installation method is reliable. If in doubt, should consult manufacturer of hose and fittings. The edge of the pipe joint is smooth, must ensure that the tail piece, collar, such as the size of the attachment, can effectively seal to ensure correct installation. Must be controlled clamping pressure and clamping torque, pressure and torque is not enough or too much, otherwise will lead to assembly premature failure. In order to insert the pipe connection hose, recommend the use of water or soap and water. Electrical performance test such as electrical performance requirements for hose and hose assembly, can regularly test according to GB 9572. Repair unless otherwise required in the relevant rules and standards, cosmetic plastic hose and hose assemblies shall periodically test or inspection, to ensure its continuing use of applicability. Should pay special attention to the hose joint and nearby, and the hose of normal aging or use, misuse or accident damage caused by abnormal cases caused by performance deterioration.
