Metal hose is an important part of modern industry. Wire and cable protection tubes and civil shower hoses used as signals for wires, cables and automatic instruments, from 3mm to 150mm. The small caliber metal hose (inner diameter 3mm-25mm) is mainly used for the sensing line protection of the precision optical ruler and the protection of the industrial sensor lines. Its main functions are:
First reducing the installation stress of the pipe
In complex piping system, there are many difficulties in installation work due to the limitation of the space location conditions: the pipe can not be installed, and the pipe that is bent past and coming up will inevitably cause partial cold correction. Depending on the diameter of the tube and the actual situation in the field, the cold correction amount is from several millimeters to dozens of millimeters, and some are hundreds of millimeters. It has been proved that the greater the amount, the higher the internal stress, and the residual stress in the pipeline system, which is undoubtedly a great hidden interest. Some type of bearing lubricating oil conduit in some type of engine has many faults in actual operation, which is caused by excessive installation stress.
Because the metal hose can bend at any time and the internal stress generated by bending under the condition of rated bending radius is very small, it can bring great convenience to the installation work, and it also plays a certain role in ensuring the safe operation of the pipeline system.
This is the main reason that some piping systems must use a metal hose.
Two position movement of compensation pipe
Due to the need of loading and unloading die, the movable cylinder on the vulcanizing machine will move upwards and downwards. After the reciprocating movement of the copper snake tube, the fatigue fracture will occur, although it can continue to be used after repair, but the parking repair will cause time loss. Although the rubber tube has good softness and strong fatigue resistance, it is also a weak link in pressure, temperature resistance and aging resistance. After several months of use, it can no longer continue. The good comprehensive performance of the metal hose is fully reflected here.
In general industrial field, besides pressure and temperature, there are often some harsh conditions such as fatigue, corrosion, vibration, compression, impact and so on. In such a case, it is most appropriate to compensate for the location and movement of pipelines with metal hoses.
Three absorb vibration of piping system
The metal hose on the connecting pipeline, not only can absorb part of the vibration generated by the noise, but also absorb fluid pulsation in the pipe system noise, greatly improve the housing environment. Metal hose can absorb vibration, it can not only improve the ability of system fatigue damage, but also can reduce the effect of noise reduction. Therefore, the pipe system of some giant buildings is used with metal hose, because this is the reason.
