WN Flanges are cut to the specific length of the flange. The process is very same in making of Nylon Flange. As the flange is cut, the Nylon fabric is stretched and it is cut as it is stretched. The Nylon material is then put in a water bath and the water bath is removed by a vacuum and the Nylon fabric is dried.What is the most important point of how to cut WN flange?The most important point of WN flange is ensuring the proper thickness of the WN material. As the flange is cut, the Nylon fabric is stretched and the amount of the Nylon material must meet the correct amount needed by the cutting tool. It is also important for the machine to be precise so, it can cut the right amount of fabric.

WN Flanges are made of non-metalThey are designed for 3.5" / 7 cmThere are 9 steel rings all around the flange to meet the 5 ringsAll rings are made with non-mild steel (not all are good).Each ring is cut with a unique technique.
How to distinguish WN flange and butt welding flange?WN Flange has a flange style that is similar to the one seen in some other WN Flange. The flanges on these Flanges are often a lot wider than other WN Flange. They are not flanged enough that the welds are too deeply buried but they are still welded correctly. WN Flange that may use other flanges might not have a very high clearance and the back of the rear flange might be too close to the bumper. 
WN FlangeWN has a flange system that is capable of the welds of WN FlangeHow to install WN Flange ?WN flange is made with non-magnets that will help weld on stainless steel, stainless steel plates and other material that resist the heat generated when welding stainless steelIf you are unsureHave you never welded before ?
WN joints should be inspected to ensure that the flange is tight. The flange must have a minimum distance of 1 2/3 inches between it and the end of the tube before welding. The distance must be approximately 1/64th inch with a minimum thickness of 0.5 in. A welding torch must be used if the flange is not located to the left or right of where the torch should be. A flange located in a position that interferes with the arc and/or flame of the torch should be avoided.Inspect the welded part of the joint with a welding torch to ensure that the flange is secure. This should be done using a heat gun and eye protection.Expose the part to the welding arc, but keep welding, until the flange stops showing "hot spots" and is stable.
