Internal Coatings Maximize Flow and Reduce Friction

In many industries the loss of line pressure over time is accepted as an unavoidable problem and part of the cost of doing business. Often, this loss results from the inherent roughness of older internal coatings—such as metal cladding and thermally-sprayed metal films—or from corrosion and sludge build-up. But a solution is now provided—by the unique surface qualities of InnerArmor films…

Properties of InnerArmor Coating in Friction Reduction

First, InnerArmor films are extremely hard. Second, they have an exceptionally low coefficient of friction. Third, they are hydrophobic—they repel water. Which means that liquids slide quickly across an InnerArmor-coated surface. The net result is that InnerArmor improves flow dynamics and reduces line-pressure loss. It means that smaller diameter pipe—which costs less—can be used to move the same amount of fluid.

Effect of InnerArmor Coating in Reducing Friciton

In addition, in applications involving reciprocating action—such as pistons moving inside of cylinders—carbon-based InnerArmor films actually create a graphitic interface layer, which produces a self-lubricating effect! The coating reduces the coefficient of friction to levels as low as 0.03, and wear factors to as low as 10-7 mm3/(Nm).

Efficiency of InnerArmor Coatings

By reducing friction, InnerArmor coatings can improve efficiency and performance in a multitude of applications such as downhole oil products, automotive engines, chemical production processes, pipeline coating, pulp and paper manufacturing and more.
