The high-pressure teflon hose can withstand high temperature, how many degrees, mainly depends on its specific material characteristics, thickness, the use of environmental and possible surface treatment and other factors.
High temperature resistant range
1.General scope：
Normally, a high-pressure teflon hose can withstand a sustained high temperature of about 260 degrees.
Under the condition of instantaneous high temperature, its tolerance temperature can reach 400 degrees.
2. Special conditions
In some special conditions, such as low pressure and low speed gas flow, the heat resistance of high pressure teflon hose may be higher, even up to 300 ° C.
Material characteristics
High-pressure teflon hoses are made primarily of polytetrafluoroethylene (PTFE) materials, which have excellent heat resistance. PTFE is chemically stable, able to tolerate all strong acids (including aqua regia) , strong oxidants, reducing agents and various organic solvents except molten alkali metals, fluorinated media and sodium hydroxide above 300 ° C. High-pressure teflon hose also has the characteristics of wear resistance and self-lubrication, low friction coefficient, which makes it in a variety of complex environment can maintain a stable working state.
Application scenarios
High-pressure teflon hose is widely used in chemical industry, pharmacy, food processing and other industries because of its excellent high temperature, low temperature and chemical corrosion resistance. In the chemical industry, it can effectively transport all kinds of chemicals; in the pharmaceutical industry, it can ensure a clean and sterile transport environment; in the food processing field, it can also guarantee food safety and hygiene.
Points to note
1. Thermal expansion and contraction: although the high-pressure teflon hose can withstand low temperatures to -190 degrees, but the use of extreme low temperature, the need to consider the thermal expansion and contraction of the hose performance. Generally safe and effective limit of use temperature is recommended around -70 degrees.
2. Pressure limit: in addition to high temperature resistance, high-pressure teflon hose can also withstand high pressure (such as about 100 bar) , but in practical applications need to choose the appropriate hose specifications and models according to specific conditions.
High-pressure teflon hose under normal conditions to withstand the continuous high temperature of about 260 degrees, the instantaneous high temperature can reach 400 degrees. Under certain circumstances, its temperature resistance may be higher. However, in the use of the need to pay attention to the thermal expansion and contraction of the impact of pressure constraints and other factors.
