The pu hose is a common hose in everyone’s daily life. There are many matters needing attention in the process of use. As a professional pu hose manufacturer, I will introduce the precautions in the use of PU hoses.
a. When designing the hose pipeline, the space position of the pipeline assembly and disassembly and debugging should be ensured to avoid the interference of the mechanical device on the pipeline.
b. Compressed air should be used to remove impurities in the joints and joints before taking over. Pipes should be neat and beautiful. Attention should be paid to the working environment temperature of the hose, as it will directly affect the pressure resistance and reliability of the hose.
c. The PU hose should not be too long to reduce the air pressure loss in the pipeline. The radius of curvature of the pipeline is above the specified value, and the bent part should not be too close to the joint to avoid leakage and avoid twisting of the hose. When tightening the threaded pipe joint, pay attention to the proper tightening torque.
d. Try not to allow the pipe to rub and twist as far as possible to avoid working in high temperature working environment to prevent the pipe from rupturing. Please do not apply tensile or twisted load to the pipe, otherwise the pipe may be cracked, detached and damaged.
e. Water or heat medium oil, please use a heat-resistant water pipe, otherwise, it may be broken due to aging. If the pipe is watered, please use an intubation. If you do not use an intubation, the tube may fall off.
f. Leave sufficient allowance for the length of the piping. When installing the pipe on the quick plug, the cross-section of the pipe should be vertical, and the outer periphery of the pipe must not be damaged or elliptical. When the PU pipe is used, the working environment may have chemical gases that may Causes the pipe to crack. When the pipe is used, for example, it may affect the working pressure and even cause the pipe to rupture.
