What material is good for using in spray towers to inject water?
Thread Content
The tower is relatively small, making it difficult to carry out anti-corrosion measures inside. If carbon steel is used, it will corrode over time. PP has a relatively high price. Stainless steel, at a higher price. Composite board?
Now, the difference between carbon steel and stainless steel isn’t that great anymore, right?
How much is carbon steel? Stainless steel is still quite expensive.
Currently, the price gap between carbon steel and stainless steel sheets is narrowing. You can consider going straight for stainless steel.

How do you make the comparison? Do you compare the price of one ton of carbon steel with that of 1 ton of PP? The density of carbon steel is more than 7 times that of PP; therefore, the tower made of carbon steel needs to be at least 4 mm thick, while one made of PP requires 10 mm thickness. The volume difference is 2.5 times. Weighted carbon steel is three times that of PP, and its price is about one-fourth of PP’s; in terms of production costs, steel is likely to be more expensive than PP. There are no towers made of carbon steel, so there is no empirical data for comparison
Carbon steel plate: 3000, stainless steel: 20000. Is the price difference very small?
I mean it’s shrinking; it used to be bigger.
PP does not calculate costs based solely on weight. The production cost is much higher than that of carbon steel.
