Threaded flange is a kind of flange which uses thread to connect with pipeline. It is a kind of non welding flange that the inner hole of flange is processed into pipe thread and connected with pipe with thread.
The production of a part may be very important to the operation of a machine, but if it is only a single part, its value may not exist. Therefore, people use flange to put these large and small parts together into a complete machine or structure, and play the role of each part as much as possible. Screw tapping flange is one of the flange.
The threaded flange has the characteristics of convenient installation and maintenance. Because it can be disassembled and tightened, the use of this flange is more convenient for the maintenance and cleaning of the machine.However, it is not suitable to use the threaded flange in any case.
1. Because the temperature fluctuation in the threaded pipe is relatively large, it is strongly affected by the environment, so it is better to weld the flange in the environment above 20 ℃ or below - 40 ℃.
2. Different machines need different sizes of flanges for installation.
3. Therefore, in order to unify the standards, the state has determined the standard size of the threaded flange.
4. For the facilities with different specifications, the threaded flange with different sizes can be used.
5. Our country's regulations on the threaded flange include the specifications, forms and size parameters: the inner diameter is 48 to 408.6mm, with a wide range.
6. Flange outer diameter is about 50 - 840, bolt thickness 14 - 52 bolt hole distance is 4 - 36.
7. In the refrigeration and ventilation equipment, the production of screw flange is very common, every refrigeration and ventilation equipment will have the appearance of screw flange.
1. With a threaded flange, of course, there must be a threaded pipe to match in order to be equipped successfully. In order to meet the size of the threaded flange, the threaded pipe also has a relatively wide range of specifications.
2. These threaded pipes are generally made of the same material as the threaded flange to achieve the same quality and complete effect.
3. At present, both the threaded flange and the threaded pipe are basically made of steel material, because the steel material has strong compression resistance and good corrosion resistance compared with other materials.
4. As the steel material is relatively hard, it is very convenient and not easy to break in the process of installation.
5 It has achieved the ideal effect of using the threaded flange and is an ideal material for making the threaded flange.
6. The use of the threaded flange not only greatly extends the service life of the equipment and facilities, but also brings endless convenience for maintenance.
