Flange nut and general Hex Nut are basically the same in size and thread specification, but compared with hexagon nut, it is a one-piece gasket and nut, and there are anti-slip tooth patterns on the bottom, which increases the nut and nut. Compared with the combination of ordinary nut and washer, the surface area of the workpiece is in contact, which is firmer and has greater tensile force.
Generally, the specifications of common flange nuts are generally below M20. Because most of the flange nuts are used on pipes and flanges, they are limited by the workpiece, and the specifications of flange nuts are smaller than those of nuts. Some flange nuts above M20 are mostly flat flanges, that is, there is no tooth pattern on the flange surface. Most of these nuts are used in some special equipment and special places, and the general sales manufacturers do not have stock.
Flange face nut connection factors
When selecting nuts for flange connection, factors such as pipeline operating pressure, operating temperature, medium type and gasket type should be considered at the same time.
The gasket type, like the operating pressure and operating temperature, directly imposes requirements on the strength of the fastener material. For example, the flange connection of a low-pressure, highly toxic medium pipeline sealed with a spiral wound gasket, although the operating pressure and temperature of the pipeline are not high, because the specific pressure required to form the initial sealing of the spiral wound gasket is large, so The fasteners are required to bear a large load, so in this case, the fasteners are required to be made of high-strength alloy steel.
