The in-situ plating process was developed to coat steel components which, because of their size or location, could not be transported to normal plating facilities. ENP’s patented process was first developed to protect equipment in aggressive environments on platforms in the North Sea. However, this process is now available to most industries in all parts of the world.
This procedure is ideal for plating vessels, tanks, cooling jackets, exchanges, piping, and other equipment or components that cannot be transported to a traditional plating facility. Although in-situ plating was only occasionally practiced in the past, it has never been as practical or as economical as it is today.
The high phosphorus alloy produced by the in-situ process is metallurgically bonded to steel substrates and is free of porosity. The high strength and hardness of electroless nickel coatings in turn provides a superior resistance to abrasion and wear. Electroless nickel is commonly used to protect components against galling, scoring, erosion, fretting and cavitations. Electroless nickel coated surfaces also offers easy release and cleaning and helps protect against production contamination.
High phosphorous electroless nickel coatings are known for their outstanding corrosion resistance. They have been used for more than 40 years to solve corrosion problems in many industries, especially in oil, gas and chemical process facilities. In these aggressive environments, 25 to 75 micron thick coatings have provided years of reliable service.
