The invention provides an anticorrosion layer protective structure of a pipeline of a
directional drilling crossing section and a method for manufacturing the anticorrosion layer protective structure. The anticorrosion layer protective structure comprises a steel
pipe and an anticorrosion layer. The anticorrosion layer covers the outer surface of the steel
pipe, and a composite protective layer further covers the outer surface of the anticorrosion layer. The method for manufacturing the anticorrosion layer protective structure includes steps of (1), pretreating the anticorrosion layer of the pipeline; (2), distributing
resin adhesive; (3), discharging yarns and dipping the yarns in the
adhesive; (4), winding and forming the yarns; (5), trimming the yarns. The anticorrosion layer protective structure and the method have the advantages that the anticorrosion layer protective structure of the pipeline is excellent in abrasion-resistant and scratch-resistant performance, high-
temperature resistance and
corrosion resistance; the method for manufacturing the anticorrosion layer protective structure is high in
mechanization and
automation degree, the defect of easiness in generating bubbles due to the fact that
glass fiber cloth is adhered on the surfaces of existing anticorrosion
layers layer by layer and the shortcoming of degradation of the strength of products due to
stress concentration at interlacing points of cloth marks and the
tail ends of short glass fibers can be overcome, and the
shear strength of the protective layer can be greatly improved.
