FIELD: chemistry.
SUBSTANCE: said coating comprises the first ZnNi alloy cladding layer having a Ni content of 5% to 9% and a layer thickness of 3 mcm to 9 mcm formed on the surface of the steel pipe, the second ZnNi alloy cladding layer having an Ni content of 10 % to 15% and a layer thickness of 1 mcm to 3 mcm deposited on the first ZnNi alloy cladding layer, and a chromate film formed on the second ZnNi alloy cladding layer.
EFFECT: obtaining a heat-resistant corrosion-resistant cladding coating with improved machinability, including in the bending region of the pipeline.
