  • Method of protecting the internal surface of a pipeline against corrosion
    Patent number: 4828796
    Abstract: A method of protecting the internal surface of a pipeline against corrosion resides in introducing into the pipeline a composition comprising 0.01 to 1 part of a phosphate and a silicate. The phosphate can be sodium polyphosphate or monosubstituted potassium phosphate. The silicate can be an alkaline metal silicate or silicon dioxide. The weight ratio of the phosphate to the silicate varies from 9-50:1, respectively, and the composition includes up to 100 parts of water. The composition is formed by fusing the phosphate and the silicate at a temperature of about 800 to 10000 degrees C. and cooling the fused composition until a vitreous structure is formed. The composition is then introduced into a pipeline containing water having a P.sub.2 O.sub.5 concentration of about 0.3 to 3.5 milligrams per liter.
