Can the water guide pipe in the boiler be made of stainless steel?

The "water guide pipe" in the boiler smoke box uses the flue gas at the tail of the boiler to heat the boiler feed water to save energy.

Therefore, the most important performance of the pipeline is high temperature resistance and corrosion resistance.

Comparatively speaking, the comprehensive performance of stainless steel pipe is superior to other metals.

The conclusion is ok.

Wish you a happy life!
