How is the production process of china WN flange?The process will consist in mixing the layers, grinding, polishing with high temperature grinding tool. In this process we will apply high quality material finishing with super high temperature polishing tool using the "W" polishing process using a polishing tool of 3.2°C. The following is how the process of china WN flange is performed:- The WN flange is filled with sand and placed on the grinding table, it is then heated at 120°C for an hour and after the process of polishing has been completed, the sand will come out.If you have any questions, please don′t hesitate to ask, we would be glad to help you in the future.

How to distinguish WN flange and butt welding flange?A WN flange is a straight, straight, flat flange and a butt welding flange is some kind of tapered section, usually called a "lip flange", that encloses the weld. The WN flange generally has a diameter of one inch or less, while butt welding flanges can have a diameter of 1/4 or 1/8 to 1 inch.How are WN and butt welded together In some instances WN flanges and butt welding flanges can consist of the same flange material, but it is important to note that WN flanges can contain non-wound (stretching) welds for a number of reasons. The most common reasons are a high weld strength, or an increased thermal tolerance such as the inclusion of a flange or filler material.
How to weld WN flange?1. If you want to do a simple weld, the best way is to connect the flange with some heat shrink tape. You can use the super glue to secure the flange. If you wish to weld more complex flanges, you can use heat shrink film.2. You need to be a certified welder to do this. I highly recommend to use a Weldless or Heat Resistant process to weld with WN flanges. 3. When you are done, use a hammer and hammer to drive the flange, to connect all connections with a weld.4. Leave the flange at a safe room temperature.
What are the precautions for WN flange welding?A standard flange steel is a steel rod welded to a pre-drilled metal sleeve or flange that protects the steel from corrosion while the metal is being welded to the flange. The steel sleeve is welded to the steel flange. A welding torch is used between the steel sleeve and the flange. There are other precautions that should be taken to prevent the steel from being damaged by the flange weld.
