If the temperature in the operating environment exceeds the pipe's limit, the pipe will begin to slowly melt. This not only affects the normal operation of other components but also causes the pipe to lose its intended function. In the past, it may have been challenging to find a type of pipe that could meet such requirements. For instance, in boilers and combustion chambers, pipe systems are needed to transport fuel. In these areas, due to the combustion of fuel, the temperature can be extremely high. Even though steel pipes have a relatively high melting point, they may not be able to withstand such high temperatures. Once the temperature in the operating environment approaches the pipe's limit, the performance of the pipe will significantly degrade.
