What is Master Bolt?
Master bolt, which stands for stud bolt or threaded rod, is the most widely used in the oil and gas industry. You should also know that Master Bolt is one of the main connections in the petrochemical industry. Other industries such as the construction and mining industries use Ostad Bolt, and the production lines of machinery and automobile industries and the cement and water and sewage industries are also not without this part, and it is considered one of the basic components of the mentioned industries.
Master Bolt can be considered a specialized type of fastener. Because its most use is to close flanges and other metal parts. Flange connections will be made with a special type of screws called Studbolt. Do you know about flanges? Flanges are a type of connecting pipes, valves and devices to each other, which look like a disc, which provide the connection of two parts to each other with the help of screws and bolts.
Master Bolt’s appearance
If we want to describe the appearance of Master Bolt, we must say that this type of screw is a threaded rod that is closed with a hexagonal nut on both sides. This tool is used together with two heavy nuts, which are called huinut. Normal screws have heads, but master bolts do not have heads, that’s why they are called headless screws.
At present, Nikan Tek Iranian Company is able to produce and market all kinds of industrial and utility bolts and nuts. Advanced technology and devices are used to make master bolts and this company produces its products daily with the best materials and standards.
What are the specifications of Master Bolt?
A number of screws are used for each flange connection, the amount of which is determined according to the number of holes in the flange. The type and pressure class of the flange determines the diameter and length of the screws. Regarding the length size, you should know that inch bars are defined according to the ASME B16.5 standard.
The distance between the first and last thread determines the length of each master bolt. Therefore, the chamfers that exist before the thread of both ends of each rod will not be considered as part of its length. It should be noted that to calculate the length of the metric rods, they also consider the widths on both sides.
