Why do spiral coolers use stainless steel pipes
A spiral cooler is a part of a refrigeration system and is a heat exchanger that converts a gas or vapor into a liquid and transfers heat from a pipe to the air near the pipe in a very fast manner. The operation process of the spiral cooler is exothermic, and the temperature of the spiral cooler is higher. Therefore, the spiral cooler has high requirements for stainless steel pipes.
1. Good heat transfer performance: generator condenser, when the raw material of the cooling pipe is replaced with stainless steel brass, heat exchange: both sides of the heat exchange pipe, that is, the heat dissipation form and heat dissipation coefficient on both sides are the same, only the material of the heat exchange pipe and the heat dissipation coefficient are the same. Wall thickness causes a change in wall resistance, but the change in wall thickness is relatively small.
2. High strength: The strength and elastic modulus of stainless steel are higher than those of copper. However, since the original pipeline is seismically calculated according to the natural frequency of the pipeline, the speed of the steam turbine caused by resonance is avoided to be 3000rp/s, which makes the gap between the partitions relatively large.
