Brass Ni-Carb Barrels
Ni-carb barrels are precision honed before plating. A hard nickel composite coating, containing silicon carbide hard particles distributed throughout, coats the entire barrel including the threads. The inside diameter is subsequently polished to finished size. Available Ni-carb plate thicknesses are 0.0015” minimum or 0.003” minimum.
The impermeable hard nickel coating offers substantially improved corrosion resistance and the silicon carbide hard phase increases wear resistance. Featuring hard nickel composite containing silicon carbide particles plated inside a precision honed C443 admiralty brass tube to form a tough and low friction matrix.
They are recommended for moderate abrasive and severe corrosive well conditions.
