Lubricant Additive For High Pressure, Temperature Conditions
Chemtex's specifically formulated extreme pressure lubricant, is for use in drilling equipment, to counteract the lubricating deficiency at high pressure and high temperature conditions. When the pressure between two operating metal surfaces rises, most of lubrication squeezes out and hence become difficult to operate.
The lubricant produces a surface layer with a shear strength lower than the metal surfaces, which enables it to form a protective coating, reducing friction, wear-tear and surface scoring.
Why is lubrication required?
It is of utmost necessity to lubricate the bit and the stem, while drilling, otherwise the frictional force between the drill string and wellbore / casing can lead to several problems, causing high torque and drag. This leads to premature damage of drilling tools, owing to extreme drilling conditions.
