METHOD OF MOUNTING PIPELINE FOR TRANSPORTATION OF AGGRESSIVE MATERIALS Russian patent published in 2004 - IPC

Abstract RU 2222747 C2

FIELD: oil and gas producing industry; construction. SUBSTANCE: according to invention metal shells of definite length with one layer of low-carbon or low-alloy steel and one layer of corrosion-resistant steel are welded to pipes made of low-carbon or low-alloy steel, then coating is applied to inner surface of each pipe and its mated shells, said coating is made of corrosion-resistant non-metallic material, after which butt joint is welded. Length of shells is 100-200 mm, and inner layer of shell is of thickness not less than 0.5 mm, being made of ferrite corrosion-resistant steel containing above indicated components. Relationship of different components is specified in description of invention. EFFECT: improved reliability of pipeline. 6 cl, 1 tbl
