The most common problem is pipe blockage, hehe
The most common issues are blockages in the sulfuric acid pipes, freezing of water pipes, freezing of hydrochloric acid pipes, as well as crystallization in alkali arthroscopes and chlorine water pipes
The first is anti-freezing; the second is the thermal expansion and contraction of non-metallic pipes. These are the two main aspects we are focusing on at present
Crystallization, frozen tubes, valve leaks – all are caused by temperature differences
Can hydrochloric acid freeze as well? ? Be careful of pipes freezing and cracking, which can cause unnecessary losses

When winter arrives, some pipes in chlor-alkali plants are prone to freezing, such as chlorine water pipes, primary water pipes, pure water pipes, etc. For certain types of steel pipes, anti-freezing measures can be taken by installing heating tubes; but how can fiberglass pipes be protected from freezing? Another time, for water pipes, what other methods are there besides having water flow continuously? ?
