The three major roles of luoying metal hose

The three major roles of luoying metal hose
1, the installation of the pipeline is subject to force in the complex piping system, due to the constraints of space and location conditions, the installation work is often a variety of difficulties: the formed pipe can not be installed; local cold correction inevitably occurs. According to the pipe diameter and site specifics, the amount of cold correction varies from a few millimeters to tens of millimeters, and in some cases up to hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress, and the installation stress left in the piping system is undoubtedly the largest. A certain type of engine a section of bearing lubricating oil pipe in the actual operation of several fracture accidents, is the installation of stress is too large. As can be bent at will, in the rated bending radius bending generated by the internal stress is small, so can bring great convenience to the installation work, the operation of the pipeline system also plays a good role. This is the main reason why some piping systems use metal hoses.
 
2、The position of the compensation pipeline will be moved up and down by the movable cylinder on the vulcanizing machine due to the need of loading and unloading the mould. Copper serpentine tube reciprocates many times, fatigue fracture will occur. Although it can continue to be used in the future, the discontinuation of use will cause time loss. Although the rubber hose is flexible, it is weak in pressure and temperature resistance, etc. Generally, after a few months of use, it can not continue to use. The good comprehensive performance of metal hose is fully reflected here. In general industry, in addition to pressure and temperature, there are often fatigue, corrosion, vibration, compression, shock and other harsh conditions, in this case, it is appropriate to compensate for the position of the pipeline movement. 3. Absorbing vibration of piping system In a giant building, the air conditioning of the hall is provided by a 6FWB unit fixed in the basement. The vibration of the unit is transmitted to the floor hall through the bridge connecting the pipes, and the noise value reaches 45 dB. In such an environment, people always have a sense of discomfort. After improving the design, metal hoses were connected to the connecting pipes in series, which not only absorbed part of the noise generated by the unit vibration, but also absorbed a large amount of noise generated by fluid pulsation in the piping system. At this time, the noise value of the ground hall is only 33dB, matching the environment in the hall. Metal hose can absorb vibration, not only can improve the fatigue damage capacity of the system, but also can achieve the effect of noise reduction. This is why some piping systems use metal hoses.
