FIELD: anti-corrosion protection of pipe-lines. SUBSTANCE: two lengths of pipe made from same material as pipe-line are used as current-insulating inserts. Adjacent ends of lengths are insulated one from another by dielectric material and are linked by means of permanent coupling joint. EFFECT: improved electrochemical protection and decreased expenses. 3 dwg
