A metal hose consists of a corrugated tube, a wire braid, and fittings. Metal hoses are corrosion-resistant, capable of withstanding both high and low temperatures, lightweight, and highly flexible. They are primarily made of stainless steel. Stainless steel hoses exhibit excellent flexibility, corrosion resistance, high-temperature resistance, wear resistance, tensile strength, and water resistance. What should you pay attention to when purchasing stainless steel metal hoses?
It is widely used in both industrial and domestic applications. Before installation, provide an overview of the types of metal hoses, their deployment conditions, and pipe diagrams, and attempt to match them accordingly. For obvious alignment, the inner sleeve of the coupling and the secondary medium flow feasibility within the metal hose’s inner sleeve should be compensated. The plane of the metal hose should align with the plane of the rotating active cruise. The domestically produced “cold-sealed” metal hose, with the aid of prefabricated pipes, can only be disassembled and installed with considerable effort.
Install non-metallic elements to twist the metal hose of the pipe, thereby reducing the resistance of the conduit and compensating for the excessive weight of pipes and equipment that could affect normal performance, service life, and impact loads, as well as the supporting components themselves. During the shaping process of the metal hose, splashes of welding slag are allowed to escape outward through the outer casing. When the metal hose assembly is closed, a coil-type expansion joint should be installed in the assembly as soon as possible to help secure the preformed metal and fasteners, and plugs adjusted to the designated positions should be installed as needed. The piping system must have sufficient capacity to accommodate wood grids within the environment.
When selecting a stainless steel metal hose, the first consideration is the medium’s temperature—the operating temperature and range of the medium within the stainless steel metal hose, as well as the ambient operating temperature. At high temperatures, you should determine the pressure after temperature correction based on the temperature correction factor for the high-temperature working pressure of the stainless steel metal hose, thereby identifying the correct pressure rating.
Whether the medium used with stainless steel corrugated hoses is corrosive depends on the medium itself. For information on the proper use and installation of metal hoses, as well as the correct hose length when accounting for thermal expansion and contraction, please refer to the guidelines provided.
The length calculation of stainless steel metal hoses under various operating conditions, the small number of bends in the hose, and the small bending radius—all these factors are crucial. It is important to correctly select and install the length of stainless steel metal hoses. Also, pay attention to the pressure range of stainless steel hoses. Based on the actual working pressure of the metal hose, verify the nominal size and pressure rating of the corrugated metal hose.
