When choosing high pressure sleeves, first of all, you should pay attention to the manufacturer, because they most likely will not, similar and interchangeable.
If any components are already installed on the equipment, then you should take into account their manufacturer before the choice.
Before choosing a high pressure sleeve, you need to find out what the length of the hose is needed, what is the size of the sleeve, the way of laying. All this should be in the initial project. Be sure to inspect the appearance of the RVD. It should not have cracks and bumps. When replacing the old sleeve with a new, check the compliance of the standards and sizes. Find suitable high -pressure sleeves on . all. Biz is very simple.
If the RVD operates at a temperature above the recommended, then its service life will be significantly reduced. Therefore, when choosing, refer how recommended the temperature of the fluid and the environment. Take into account the influence of the external heat source if one will.
Each RVD has permissible internal pressure parameters created by the liquid inside the sleeve. Make sure that the sleeve does not stretch and does not twist. There should not be external extraneous loads on it. If this rule is violated, then its ability to withstand the set pressure will be significantly reduced. If there was no excess of the RVD, then you should use the fittings. In addition to fittings, the quality of crimping affects the service life.
RVDs are divided into two types, which determines the type of hose amplification. So there are hoses having a metal braid or metal navigation. But these are the most common. In addition, more highly specialized RVDs are produced. So there may be a textile braid, rubber layer, etc. D. But such sleeves are in demand very rarely.
