What is the material of the oil cooler in the lubricating oil of the centrifugal compressors in ethylene plants? Some say naval copper is used for such constraints, while others use 316L entirely. Can 316L be used in circulating water systems with a chloride concentration of 300–400?
It seems that copper-nickel alloys and duplex stainless steel are used quite often, right? Fiberglass works too.
There is also the effect of temperature; generally, corrosion of stainless steel by chloride ions occurs only at temperatures above 60°C. In the conditions typical of gas stations, 316L stainless steel can withstand chloride ion concentrations of up to 700 ppm.
The 316L material should work.
