Customer purchase A105 Blind Flanges surface need galvanized
Customers in the purchase of flange in the purchase order will indicate the surface of flange rust treatment, often we use on A105 Blind Flanges product surface rust oil, yellow paint or black paint, sometimes meet some customers will special treatment with cold galvanized and hot galvanized these two disposal methods, carbon steel A105 Blind Flanges product price is low, anti-corrosion performance is far less than stainless steel, alloy steel material of flange.In order to make the flange Anti-corrosion performance and service life extension customers choose to galvanize on the A105 Blind Flanges product surface.Customers choose galvanizing on their own, as long as we add the cost of galvanizing when we order.Flange Galvanizing has the difference between hot galvanized flanges and cold galvanized flanges.Hot galvanizing is the process of soaking A105 Blind Flanges products into condensed zinc with a temperature of 440-465℃. The iron matrix and molten zinc respond to constitute the iron-zinc alloy layer on the appearance of the whole workpiece, while cold galvanizing is the A105 Blind Flan The processing process of ges flange needs to galvanize the flange, because the cost of galvanizing is much more expensive than surface rust oil, yellow paint or black paint, customers have to galvanize the surface of A105 Blind Flanges flange due to the process of use.Although the price is a little expensive surface after galvanized treatment can play a good anticorrosion effect, but also can extend its service life.
Haokun company has from the feeding, forging, heat treatment, machining, surface treatment, packaging, and other integrated operations, the company has an annual output of 20,000 tons of flange production line, can strictly in accordance with the US standards ANSI, API, MSS, AWWA, DIN, Japanese standard JIS, British standard BS and national standard GB to design and production.
