Anticorrosive chemical device manufacturing process

Abstract

The invention relates to an anticorrosive chemical device manufacturing process. The process includes the steps of 1, device inner wall welding joint and pipe opening treatment, 2, device inner wall surface roughening treatment, 3, device oil dirt removal and stress treatment, 4, device inner wall surface washing, 5, antioxidant rolling coating, 6, device inner wall surface adhesive coating, 7, anticorrosive board shearing, 8, board face adhesive coating, 9, board adhesion, 10, board push, 11, board welding way forming and 12, welding way cleaning. By the adoption of the anticorrosive chemical device manufacturing process, when a board is attached to the surface of the inner wall of a device, vacuumization is performed firstly, then the board is heated, and a squeezing tool is adopted for pushing operation so that it can be guaranteed that the board is attached to the surface of the inner wall of the device without a gap and a bulge, the long-existing problems that the board cannot be completely attached to the surface of the inner wall of the device and is likely to be stripped in the prior art are solved, the anticorrosion performance of the inner wall of the chemical device is remarkably improved, and therefore the service life of the chemical device is remarkably prolonged.

Description

technical field [0001] The invention relates to a manufacturing process of chemical equipment, in particular to a manufacturing process of anti-corrosion chemical equipment. Background technique [0002] Most of chemical equipment and containers used to store chemical materials need to have anti-corrosion function. In order to improve the corrosion resistance of metals, corrosion-resistant plates are often lined on the inner wall surface of chemical equipment. These plates must first be installed and attached to the inner wall surface of the equipment, and then the plates are attached to the inner wall surface of the equipment by vacuuming. , and then weld the plates into a whole. The defect of this manufacturing process is that there is a deviation between the shape of the plate and the surface of the inner wall of the equipment. Since the plate generally has high strength and rigidity, the method of vacuuming cannot make the plate and the inner wall surface of the equipme...

AI Technical Summary

Problems solved by technology

The defect of this manufacturing process is that there is a deviation between the shape of the plate and the surface of the inner wall of the equipment. Since the plate generally has high strength and rigidity, the method of vacuuming cannot make the plate and the inner wall surface of the equipment completely fit, often There are gaps, and long-term use will cause the plates to separate from the inner wall surface of the equipment, thereby reducing the service life of chemical equipment
