Teflon hose may be used in a variety of severe conditions. Teflon is resistant to practically all chemicals, with the exception of a few highly potent redox agents, and retains its useful function as a hose across a temperature range of around -73°C to 260°C. It is perfect for various applications because to its lack of adhesion, low coefficient of friction, and moisture resistance. Its characteristics remain constant over time and it is resistant to bending and vibration.
Teflon hoses typically have a spiral lining or inner tube made of polytetrafluoroethylene (PTFE) and a jacket. The hose often has stainless steel metal fast connectors on both ends. Typically, the inner diameter ranges from 5 to 200 mm. There are several uses for this hose in the factory. For instance, Teflon hoses are utilized in steel mills as hydraulic, high-pressure, and lubricating oil hoses during flat die operations. On the flat casting line, there are close to 300 hydraulic cylinders, each of which has two Teflon hoses. At 93 °C and 20.7 million Pascals, these pipes supply hydraulic fluid containing phosphate vinegar (207 bar). Lubricants with temperatures ranging from -29°C to 66°C are also fed through Teflon hoses in the self-lubricating system of the flat die at a pressure of 10.35 million Pa.
Teflon hoses are widely used in the chemical industry to carry strong alkaline or extremely corrosive chemicals. For instance, LCP Chemicals employed Teflon hoses five years ago to load chlorine into tankers at -18°C instead of copper-nickel alloy tubes. The hoses’ lifespan was tripled, and the price was decreased. Mercury is poured through the pipes at 77–102 °C to produce sodium hydroxide and hydrogen. The previously utilized carbon steel pipes were soon corroded by the caustic soda corrosion at high temperatures and would leak at the joints as a result of thermal expansion and contraction. Instead of using carbon steel pipe, Teflon hose with a stainless steel wire braided jacket provides longer service life, increased safety, and decreased maintenance costs.
Teflon hose is frequently utilized as compressor pipework, fluid transfer lines, cooling water lines, oil gauge lines, and brake lines in the transportation sector. For the compressor exhaust, a 250–500 cm long, 16 cm inner diameter pipe has been used in truck engines for more than 15 years. The most crucial quality of the aforementioned application is flexibility. When Teflon hose was first introduced in the 1960s, copper hose was previously used, but it was frequently damaged over the truck’s lifetime. With stainless steel wire preparation, Teflon hose life and truck life are now about equal, decreasing repair times and maintenance costs.
Since PTFE is non-adhesive and resistant to the solvents used in coatings, Teflon Teflon hose is also utilized in the coatings industry for coating transfer and dosing. Another aspect of Teflon hoses, moisture resistance, also becomes crucial with the introduction of urethane coatings. Teflon hose can efficiently stop moisture penetration because urethane coatings are sensitive to moisture; a small amount of moisture can cause them to cure prematurely. Teflon hose may be used as an industrial ultrasonic vapor degreaser nozzle because of its flexibility and resistance to perchloroethylene and chlorinated hydrocarbon solvents.
