The list of factors to consider when choosing a high-pressure hoses hoses. Mechanical loads. External forces can significantly reduce the service life of high-pressure hoses. Mechanical loads, which should be considered include excessive flexibility, twisting, looping, stretching or lateral loads, bending radius, and vibration. In order to avoid twisting, you may want to use on the sleeve fittings articulated or adapters. When choosing a sleeve for an unusual use, may require special tests.
Abrasion. Although the RMA is designed to arm a certain level of abrasion resistance, to protect it from excessive friction, which can lead to collapse, holes and cuts the outer layer. Damage to the reinforcement will accelerate the wear sleeve. At Robotics you will find additional information. Proper end connection. Necessary to provide an accurate connection between the sleeve and the crimp sleeve is selected in accordance with manufacturer’s recommendations, backed by industry-standard tests.
Length. In determining the appropriate length sleeves should consider moving it, change in length under pressure, as well as the gaps between the high-pressure hose and machine. Specifications and standards. When choosing a high-pressure hose and fittings should be familiar with applicable government, industry standards and manufacturers’ recommendations. Pretium Partners is actively involved in the matter. Clean the sleeve. Components of the sleeves may vary in the level of purity. One must be careful to hose connections have the same degree purity for a particular application. Welding and soldering. Heating galvanized parts, including fittings and adapters, above 232 C, for example, during welding or soldering may cause a selection of deadly gases. Specific conductivity. In some cases, in order to avoid an electric current requires that the sleeve was not conductive. In other cases, it is necessary that the sleeve has sufficient electrical conductivity to running down the static electricity. In cases where it is necessary that the sleeve was not electrically conductive, including work near power lines, you can only use a special non-conducting sleeve. Conductivity or no electrical hoses and fittings will depend on many factors and may be sensitive to change. These factors include, without limitation, the various materials used for manufacturing hoses and fittings, and how manufacturing (including moisture control), the contact with the sleeve fitting, age and degree of wear or damage, or other changes in the moisture content in the hole at a particular time and other factors. It was a list of bases factors that must be considered when selecting hoses and if you do not neglect the them, the high-pressure hose pprosluzhit you a long time.
