The corrosive effect of chloride ions on stainless steel

2011-10-29View Original

Thread Content

There is a type of stainless steel pipe with a wall thickness of 0.6 mm. It is now to be used with frozen saline containing 20% CaCl2, at temperatures ranging from 10 to 40 degrees. What is the approximate service life of such a pipe?

The tube is too thin; it will probably last at most a year.

It also depends on the flow rate design and the equipment structure.

Without a corrosion margin, it’s completely unusable

A polymer-based chlorine reducer can be added. In the past, the most effective methods for removing chloride ions were anion exchange resins or reverse osmosis, but both required additional external equipment, which posed certain limitations in terms of operation and use. It is difficult to remove chloride ions chemically, as most compounds of chloride ions are highly soluble in water, making them hard to eliminate. The ionic chlorine remover introduced and developed by our company utilizes the world’s most advanced polymer nanotechnology; it is a macromolecular organic compound synthesized through bioengineering under specific conditions, and it is capable of rapidly removing chloride ions from water under various water quality conditions, with an effective removal rate of over 80%. This product has many advantages, such as low cost, fast response speed, simple operation, and no need for additional equipment. Contact: Zhang Wujin 13817223104 ike5@163.com

For frozen saline, it’s better to use carbon steel pipes; those with a thicker wall thickness can still be used.

Sandvik stainless steel pipes possess excellent resistance to chloride ion corrosion, or in other words, resistance to halide ions. If you would like to know more, please contact me!

Given that the operating temperature isn’t very high, carbon steel pipes lined with polyethylene or polypropylene can be used; they meet both the requirements for corrosion resistance and strength, and their price is acceptable.

Reply to 5# ike5: Dude, what needs to be transported is a CaCl solution – why go and remove the chloride ions?
