As a highly versatile flexible hose available on the market, PU Tube features flexibility, smooth inner walls, low flow resistance, reliable sealing and moderate wear resistance. These advantages make it widely adopted in various material transfer applications. It can carry many industrial and conventional civilian fluid media, though it also has clear usage boundaries for transported materials. Matching suitable media is essential to maintain stable long-term operation and extend service life.
For gaseous media transfer, this is the most common application where PU Tube performs best. In daily industrial production, automated equipment, pneumatic tools, pneumatic valves and automated assembly lines, PU Tube is primarily used to convey compressed air and serves as the standard hose for pneumatic systems. Besides compressed air, it can steadily transport nitrogen, oxygen, carbon dioxide and other common clean gases under normal or low pressure. The smooth inner wall of PU Tube reduces gas transmission resistance and releases no impurities to contaminate conveyed gas. It ensures stable operation of pneumatic equipment without blockages or leakage.
For liquid media transfer, PU Tube works with normal-temperature fluids that have no strong corrosivity. In civilian and light industrial settings, it safely delivers room-temperature fresh water, purified water and ordinary diluted water-based agents. In light manufacturing, auxiliary food processing and small-scale auxiliary chemical applications, it can carry various non-corrosive, low-viscosity lightweight liquids including general water-soluble additives and diluted cleaning solutions at ambient temperature. Its good flexibility and bending resistance adapt to moving and bent pipeline layouts without fluid transfer efficiency dropping due to tube deformation.
At the same time, users must understand forbidden media for PU Tube to guarantee safety and tube integrity. PU Tube cannot be used for strong acid or strong alkali materials. High-concentration acid and alkali fluids corrode tube walls and break down polymer molecular structures, which hardens the tubes and causes cracking and leakage. It also cannot carry benzene, ketone, ester and other high-concentration organic solvents. These solvents dissolve and swell PU materials and lead to tube failure. In addition, high-viscosity slurry, fluids with abundant solid particles and high-temperature heavy oil are not recommended, as they may clog pipelines and accelerate abrasion and aging of tube walls.
In summary, the strengths of PU Tube for material transfer lie in clean, low-pressure and room-temperature gas and liquid delivery. It is the preferred hose for pneumatic control systems and small clean fluid transport. As long as users avoid strongly corrosive, dissolving and heavily abrasive media and select ordinary clean gas and liquid materials, PU Tube can fully demonstrate its advantages of flexibility, durability, stable transmission and cost efficiency to meet fluid transfer requirements of most small and medium-sized equipment.
