The quality of rolled flange is good and the forging flange quality is good
Forging is good. Flange: it's also called flanged flange or flanged. The flange is the part of the pipe connecting the pipe to the pipe. So when has the machine and pipes, generally use flange as the fittings, and forging flange, currently USES is a molding, performance comparison thick steel made, thus using the compact connection, not easy because of the external force to pull the bad.
Obviously, the forging flange is of good quality. It's very simple, you can make a difference from their craft.
The winding flanges are mainly made of iron or thin steel, and they are formed by winding, which makes the tension of the external forces less strong and can cause damage. So the forged flange
The winding flanges cut the middle plate into the right sliver, and the length of the strip depends on the size of the large flange. Then the coil is rolled into a circle and welded to the seams. And then flatten it with the press, mud bed for processing line and chamfering, etc, finally is to use dial cooperate with drilling machine in bolt hole punching processing. The winding flanges cost less than the forged ones. But some large flanges are not forged. This type of product is heavily weighted by the theory weight, and is calculated without the weight loss of waterline, stop, bolt hole, and Angle. The price of the tablet is lower, but if you have large flanges such as a swallowtail, the price will be higher. The theoretical weight is calculated by the formula above. That is to say, big general or curly! Or the cutting board! Small, mostly forged! But overall! Forged is better than volume! Forge a lathe to process a car! The roll is bad processing! The car is very expensive!
