ANTI-CORROSION TAPE COMPRISING AT LEAST FOUR LAYERS Russian patent published in 2025 - IPC B32B25/04 B32B25/18 B32B27/30 B32B15/06 F16L58/10 

FIELD: chemistry.

SUBSTANCE: invention relates to anticorrosion tape systems used in pipes and pipelines, and concerns anticorrosion tape, method of its application, method of its production and use. Anticorrosion tape comprises at least four layers. At least two layers of anticorrosion tape in the form of bearing sheets include at least a single-layer carrier, and at least one layer of the carrier is formed as a bearing layer. At least one other sheet of anticorrosion tape is made in the form of a connecting sheet and includes at least one connecting layer, wherein the connecting layer includes a material containing at least one butyl rubber and/or at least one polyisobutylene, and at least one connecting sheet is placed between two bearing sheets. At least one other sheet of anticorrosion tape is formed as anticorrosion sheet and is placed on at least one exposed surface of at least one bearing sheet.

EFFECT: invention provides creation of anticorrosion tape, which, in particular, makes the second operation unnecessary with respect to supply of pipes, pipelines, tubular objects, pipelines and parts making up pipelines, and possibility of its functioning, providing additional properties.
