Internal coating applied in liquid form or in powder form on steel pipes used for the production and transportation of oil, gas, water, industrial and corrosive fluids, etc.
It is especially used in production and conduction pipelines and drilling tools (drilling pipes, sucker rods, packers, pumps, tubing, casing, etc.) installed in oil fields likely to cause corrosion problems and paraffin deposit, as well as in special connections for the protection of welded joints.
Given it properties, apart from innes anticorrosive protection, it improves fluids process and transportation hydraulic conditions.
After contaminants have been removed, the pipe surface is blasted to be later coated using the following alternative materials:
A. Liquid paints, which reach thicknesses of up to 300 µm and involve:
B. Powder paints which reach thicknesses of up to 600 µn and involve:
