Issues that Need Attention in The Use of Stainless Steel Metal Hoses
Different types of stainless steel metal hoses have different bending radii. Their ratings are very small. Generally speaking, within such a large range, it is not difficult to accurately and appropriately determine the actual bending radius of the hole. If repeated bending pain and stress concentration will indirectly threaten the service life of the metal hose; if R tends to infinity, the original length needs to be increased, which will directly affect the structural design of the system. Additional vibration will be generated; the metal hose used in the piping system is too long, which will produce less fluid resistance, etc. Of course, shortening their length can avoid the above-mentioned problems. However, blindly shortening can not achieve the purpose of compensation, vibration reduction, and noise reduction. At the same time, other advantages of metal hoses have not been fully reflected. Therefore, determining the length of the metal hose is a very critical task.
The use of rigid elbow joints eliminates torsion and obtains a satisfactory bending state. Use rollers equal to the bending radius to eliminate excessive bending of the stainless steel metal hose. Use a movable roller with the same bending radius to eliminate the bending and twisting caused by the staggered stainless steel metal hoses. Use the bottom plate to prevent the stainless steel metal hose from bending. Two rigid bending plates are used to eliminate the staggered bending and twisting of the stainless steel metal hose. Separate and fix two cross stainless steel metal hoses with special clamps to avoid friction damage.
Due to the needs of mold loading and unloading, the movable cylinder above the vulcanizer will move on both sides. After repeated reciprocating movements, the copper serpentine tube will break. Although you can continue to use it after repairing, repairing the parking machine will cause time loss. The hose has good flexibility and strong fatigue resistance, but its compression resistance, temperature resistance, and aging resistance are weak items. After several months of use, it can no longer be used. It fully embodies the good overall performance of the metal hose. In general industrial fields, in addition to pressure and temperature, there are also severe conditions such as fatigue, corrosion, vibration, compression, and impact. In this case, it is more appropriate to compensate for the positional movement of the pipeline.
