Liquid chlorine vaporizer is a kind of equipment that converts liquid chlorine into gas. It is mainly used in the chlor-alkali industry and is the key equipment in this industry. The common types are mainly tubular vaporizer and coil vaporizer. The liquid chlorine vaporizer will encounter some common faults during its use. As users, we should know how to solve these problems.
The main reason for the failure of the liquid chlorine vaporizer in the process of use is corrosion, but this kind of corrosion is not a single one, which can be divided into several categories, such as crevice corrosion, pitting corrosion and stress cracking corrosion. This article will focus on one of them to see how to solve the crevice corrosion problem.
Crack corrosion is one of the more common problems, which mainly occurs in the form of cracks, mostly in places with insufficient oxygen supply. It can occur in the same material or in different materials, but at least one of them is metal material.
In order to avoid and solve the problem of crevice corrosion of liquid chlorine vaporizer, the sufficient supply of oxygen should be guaranteed in the production process, because the probability of crevice corrosion will be very small when the supply of oxygen is sufficient. Secondly, try to avoid the formation of sedimentary layer during production. Another very effective way is to increase the content of molybdenum in the alloy, which can effectively prevent corrosion.
