Introduction of Slip-on Flange Forging Methods
This technical article introduces us about some main forging methods of slip-on flanges according to the movement of the forging die.
How to Correctly Select Flange
This technical article introduces us in details about that some main ways and methods that we can choose and select flanges correctly.
Thin-walled SS Tube Is Increasingly Widely Used
With the implementation of reform and opening policy and the development of economy, thin-walled stainless steel tubes are more and more popular.
Venezuela's Manufacturer Will Set Up Factories in Cuba
The company is evaluating the factory of the pipeline construction project, thus it is going to set up factories in Cuba.
NDRC: Increase Gas Imports and Oil Reserves in Winter
The National Development and Reform Commission decided to increase gas imports and oil reserves in this winter in the meeting held on November 13.
What kinds of Polishing Methods used for Large Flanges?
Electrochemical polishing is also called electrolytic polishing. In the process of electrolytic polishing, large stainless steel flange is considered as anode, insoluble metal is considered as the cathode, put the two poles into the electrolytic cell at the same time, power on direct current (dc) to produce selective anodic dissolution, thus increasing the surface brightness of large stainless steel flange, achieving mirror effect. Environmental protection formula of electric polishing liquid is without chromium anhydride and less dosage of phosphoric acid, reducing the pollution emissions. Formula without phosphoric acid and chromic anhydride solves the environmental problem of wastewater discharge, is a brand new type of pollution-free green electrochemical polishing agent, Its technological process such as processing conditions are the same as the original basically, polishing effect is also basically the same, having ensured the polishing quality. In the process of production, the surface of stainless steel is easy to appear some black oxide coating or micro inequality, influencing its use value. Only reprocessing such as mechanical polishing, chemical polishing and electrochemical polishing treatment is adopted to improve its own value, good results can be achieved.
