Problems solved by technology

[0002] At present, there are mainly two kinds of coating processes for industrial steel pipes: hot-dip coating and cold coating, and the coating is generally zinc-aluminum elements. Although zinc-aluminum elements are coated on the inner and outer surfaces of steel pipes, the steel pipes have certain corrosion resistance, but the resistance The corrosion performance is poor, and this kind of steel pipe cannot be galvanized continuously on-line, so that it lacks sufficient competitiveness, which is reflected in the hot-dip galvanized aluminum steel pipe disclosed in the Chinese patent application number 201120409121.3

Embodiment Construction

[0012] The present invention will be further described below in conjunction with embodiment.

[0013] Referring to the accompanying drawings, the online continuous coating process of this embodiment: place the raw material black steel strip on the uncoiler, subtract the initial part of the steel strip through an automatic shearing and welding machine, then carry out lettering (engraving the company's product code), and pass through the pinto Adjust the frame and the adjusting frame, and enter the spiral loop feeder to adjust and control the feeding speed. After passing through the high bracket, the front and back sides of the cleaning equipment are washed by high pressure water, and the cleaned steel strip flows into the next link: using the coiling equipment The steel strip is rolled and formed to get the pipe; the formed pipe enters the automatic welding equipment, and the joint is subjected to high-frequency welding; the welded part flows into the next process, and the raise...

Abstract

An online continuous plating process comprises placing a raw material black steel belt on an uncoiling machine, shearing an initial portion of the steel belt through an automatic shear welding machine, performing lettering, performing adjustment through a flat supporting frame and an adjustment frame, entering a spiral loop feeding machine to perform adjustment control on the feeding speed and performing high pressure water washing, rolling pressure forming and high frequency welding after passing through a high supporting frame; cutting protruding welds which are formed at the welding position; removing the residual water on the inner wall of a steel pipe through an air cutter, enabling zinc-rich paint to uniformly coat the inner wall of the steel pipe through a spraying gun, performing pickling and preheating and simultaneously baking the zinc-rich paint in the steel pipe; immersing the liquid zinc to the outer surface of the steel pipe through a zinc pump to form the zinc bonding, performing X-ray cooling, performing an online eddy current inspection test, flowing into a sizing unit to shape, performing chrome plating treatment, performing a UV (Ultra Violet) coating process, performing drying and cutting, performing end chamfering end-flatting and inkjet coding and performing automatic packaging. According to the online continuous plating process, the online continuous pipe production and zinc plating is adopted and accordingly the production efficiency can be improved, the labor cost is reduced, the product flexibility is high, and the product competitiveness is improved.
