Internally Coated Fittings Flanges

Why Internal Coating ?

Oil and gas fluids contain solid particulates such as sodium chloride, potassium chloride, other salts, carbonates, sulfates, partially polymerized oils, including waxes and paraffins as well as silicas, dirt and greases. Some of these particulates dissolve in the fluid while some remain in suspension. Traveling through pipelines at speeds approaching 200 mph, these particulates become aggressively corrosive projectiles. Coatings designed for internal pipeline application must be engineered to withstand the high impact created by these fast moving particulates. Internal Pipe Coatings have been designed to protect the internal surfaces of (steel) pipe against corrosion as well as provide flow enhancement.
