Various Types of Stud and Bolt
Various types of studs and bolts are manufactured and used in different industries.
These studs are mainly made from iron or steel. They are used in various applications like oil refineries, pipelines, and flange joints. Stainless steel is another popular material used for making studs and bolts. Metal is mostly used in the oil and gas industry.
Depending on the material, the stud and bolts are made in different grades. They are also manufactured in different diameters. The size of a stud is determined according to the pressure class of the flange. In some cases, the studs are manufactured with different plating and plastic end caps. Moreover, studs are available with different thread profiles.
A stud and bolt are similar to a screw in that it consists of three components: the stud, the nut, and the bolt head. However, the nut has a hexagonal shape while the stud has a flat head. The stud is placed in the hole of a flange and the nut screws into the stud. When the two pieces are connected, the clamping force generated by the nut results in an even distribution of the torque load. Using a wrench, a technician can loosen or increase the tension.
Various studs and bolts are designed and manufactured to fit into the holes of mating flanges. They are also used in manufacturing, oil and gas, and general industries. They are usually used in high-pressure bolting situations. They are also used for sealing. They are manufactured in imperial and metric sizes. Usually, studs and bolts are identified by their grade marking and material identification stamp. Besides this, a number of studs and bolts are manufactured with different thread profiles. Some of the common thread profiles include UNC, UNF, and ACME.
The thread pitch on a stud and bolt is measured in threads per inch (TPI). It is important to determine the proper thread pitch. There are two main types of thread pitches: symmetrical and non-symmetrical. The symmetrical thread pitch type is easier to inspect. Nevertheless, non-symmetrical types are harder to inspect.
Typically, the most commonly used thread pitch is symmetrical. Basically, it means that the angle of the threads is 60 degrees. It is considered to be the most useful. It is useful in many applications, such as steel, aluminum, and copper.
When studs and bolts are heated after manufacturing, they develop higher mechanical strength. They are also treated to provide greater stress tolerance. After this, the studs are annealed or tempered. They are then subjected to additional heat to ensure their tensile strength. They are ideal for use in industries with temperatures between 200 and 575 degrees Celsius.
In addition to the above, the material of the nut must be compatible with the mated stud. This is done by slightly stretching the bolt before the nut is inserted. There are various types of nuts and bolts, including hex nuts, acorn nuts, and oval nuts. The type of nut and bolt used for each application depends on its purpose. For example, a hex nut can be used for quick screwing while an oval nut is used for more accurate screwing.
