Electroless Nickel in Chemical Processing

A key consideration for the Chemical Processing Industry is finding a way to extend equipment life without affecting the purity of the product. Electroless Nickel is a conversion coating that is able to form a protective barrier for a range of parts. One of the great advantages of the process is and depending on its thickness and phosphorus level can be used to counteract a number of different chemically corrosive environments.

Conditions

ENP is suitable for use in protection against a wide range of different chemicals. These include Sodium Hydroxide, Phosphorus Oxychloride, Benzoyl Chloride, Benzitrichloride, Phosphoric Acid and many more. Low Phosphorus deposits (1-2%) perform better when dealing with Alkaline solutions such as Sodium Hydroxide. Medium Phosphorus deposits (7-9%) will perform similarly to Stainless Steel and can combat chemicals acidic in nature. High Phosphorus Deposits are better when dealing with acidic corrosion from chemicals such as Phosphoric Acid.

Minimum Thickness is typically recommended at 40 microns but for more corrosive environments 75 microns may be better suited. In order to get the best results, proper surface preparation is needed.

Suitable for:

Steel Compressors, valves, cooling tower equipment such as pumps, nuts and bolts, heat exchangers, filter units, pump housing impellers, mixing blades and more.
