Mandrel have been plagued with excess wear, corrosion, erosion, de-lamination of chrome and low drilling times due to the high drilling tool rental. Most hydraulic mandrels have historically been chrome plated or nickel plated. Due to the flexing and drilling pressures, these traditional coatings have limitations.
Select appropriate coatings to increase drilling times, reduce wear, increase corrosion resistance and reduce repair times.
The application of SuperChrome I, SuperChrome II and Armorclad considerably improves the chemical resistance, increase wear resistance and better corrosive resistance to both alkaline and acidic environments.
Main benefits are lower porosity, harder coating, quicker repair times and increased production life. Switching from hard chrome eliminates the historical issues of fractures in coating allowing for de-lamination of coating and pathways for contamination to penetrate to the substrate material.
