What is the advantage of flange bolts
Could it be tighter? Ordinary bolt heads are thick, hard to shape, and vibrate when they are well. The flanged parts of the flanges can be slightly shaped, and can be more firmly locked. And on into the hole, if ordinary bolts can't do the tool use, flange bolt head is small, also play a role fastening flange plate below, but can use a special tool into the hole, and socket head bolts around the same principle. Again is flange top flat cushion to use, the material that is softer, not wear-resisting is safer, do not cause perforation. The above is a personal guess, only for reference.
The flange is the connecting device of two large diameter pipes, usually two flanges and several fastening bolts. Carbon steel flanges are the flanges of carbon steel. Low carbon steel has a low plastic strength, and when added to the right amount of carbon, it becomes hard and the plastic decreases strength. Flange connection is likely to be high tensile, compressive, anti-twist and shear strength, and carbon steel flange is a good choice. The determination of nominal pressure not only according to the maximum working pressure, still need according to the maximum operating temperature and material characteristics, not only meet the nominal pressure is greater than the pressure of work.
What is a flange bolt? In general, the flange is a way of heat treatment. A bolt is connected to an object
A bolt is a removable removable connection that connects an object's part The flange is connected to the valve
