specific Embodiment approach
[0032] As a specific embodiment of the pipeline anticorrosion coating processing method provided by the present invention, wrapping the stainless steel coil with the topcoat on the outer surface on the cast iron pipe includes:
[0033] In the process of unwinding the stainless steel coil, the outer surface of the stainless steel coil is sprayed with topcoat.
[0034] The stainless steel coil is wrapped along the axial direction of the cast iron pipe or spirally wound on the cast iron pipe around the circumferential direction of the cast iron pipe.
[0035] Since the finish paint with certain flexibility is selected, the finish paint can be pre-sprayed on the outer surface of the stainless steel, and then the stainless steel is wound into a stainless steel coil. For manufacturers with operating space, the topcoat can be sprayed when the stainless steel coil is unrolled to avoid damage to the topcoat. The stainless steel coil can be wrapped along the axial direction of the cast...

Abstract
The invention provides a pipeline anti-corrosion coating processing method, and belongs to the technical field of pipeline coatings. The processing method comprises the following steps: 1, the surfaceof a cast iron pipe is preprocessed, and a preset standard is reached; 2, a stainless steel coil coated with finishing paint on the outer side of the stainless steel coil wraps the cast iron pipe, and the inner side surface of the stainless steel coil is bonded and fixed to the cast iron pipe; and 3, blocking glue is applied along the side edge of the stainless steel coil. The finishing paint provided by the pipeline anti-corrosion coating processing method can be pre-sprayed on the stainless steel coil, and after the pre-treatment of the cast iron pipe is completed, the stainless steel coilcan be bonded to the cast iron pipe in a short time; compared with the traditional mode that the stainless steel coil and the finishing paint sequentially spray the cast iron pipe, the spraying of thefinishing paint and the pretreatment of the cast iron pipe can be carried out independently; and compared with spraying, by a wrapping mode, the coating method not only improves the anti-corrosion effect, but also improves the working efficiency, and reduces the resource waste and cost investment.
Description
technical field [0001] The invention belongs to the technical field of pipeline coatings, and more specifically relates to a processing method for pipeline anticorrosion coatings. Background technique [0002] With the increase of the service life of the buried earth graphite cast iron pipeline, the outer wall coating and the pipe wall will corrode. In severe cases, the pipeline will be perforated or even ruptured, leading to failure of the pipeline and further causing leakage. Existing anti-corrosion treatment is usually carried out by spraying anti-corrosion material on the cast iron pipe. Due to the long length of the cast iron pipe, the processing time is long, the work efficiency is low, and the cost input is relatively large. Contents of the invention [0003] The purpose of the present invention is to provide a pipeline anticorrosion coating processing method, which aims to solve the problems of long processing time, low work efficiency and large cost input. [000...
