Production technology of Galvanized flange
In the pipe fittings, especially the consumption of flange and elbow, often use cold galvanizing and hot galvanized these two disposal methods, to improve the anti-corrosion performance and service life of flange, after all, the flange of carbon steel material cost is low, anti-corrosion performance is far better than stainless steel, alloy steel and other material flange. Haokun company also has customers sometimes according to their own needs, choose a certain galvanizing way. When communicating with our customers, we should ask whether the customer requires a hot-dip galvanized flange or a cold-dip galvanized flange? Because there is a difference between hot galvanized and cold galvanized flanges. Since it is called "hot-dip galvanized flange" and "cold-dip galvanized flange", it is obvious that the galvanized temperature in the application process is different, so the galvanizing process is also different. Hot galvanized flange process is, the first is the flange into 440-465℃ of condensed zinc stop disposal process, iron matrix and molten zinc response, in the whole workpiece appearance form iron-zinc alloy layer, the price of g zinc flange is different, we in the customer offer must communicate clear customer is the price of hot galvanized flange or cold galvanized flange price. Galvanized flange customers also have technical requirements, our customers recently purchased a batch of Galvanized flanges, customers purchase most of the flange surface requirements for galvanized treatment, yesterday in the weekly meeting of our manager and foreign trade sales salesman colleagues discussed the customer about the galvanized flanges. This customer also made an order for a galvanized flange last year. Our factory processed the sealing surface of the flange. The galvanized layer on the flange sealing surface caused the factory to reprocess the sealing surface. This time, our manager suggested that the process flow of galvanized flange can be changed, and then the first hole and galvanizing process is finished before processing the flange sealing surface. Changing the process flow of galvanised flanges is also a good recommendation。
