Types of Stud Bolts
Depending on the threading pattern and design, various types of stud bolts are available as listed below:
Depending on the threading pattern and design, various types of stud bolts are available as listed below:
* Fully threaded stud bolt or continuous threaded stud bolt having uniform thread throughout its length.
* Tap end stud bolts having unequal threads from each end and non-threaded center.
* Double-end stud bolts having both ends threaded of equal lengths and a non-threaded center.
* Flange Stud bolts: Fully threaded stud bolts with chamfered ends specifically used for flanged connections.
* Double-end stud bolt with reduced shank: the non-threaded center part is of a reduced diameter than the actual diameter.
* Tap end stud bolts having unequal threads from each end and non-threaded center.
* Double-end stud bolts having both ends threaded of equal lengths and a non-threaded center.
* Flange Stud bolts: Fully threaded stud bolts with chamfered ends specifically used for flanged connections.
* Double-end stud bolt with reduced shank: the non-threaded center part is of a reduced diameter than the actual diameter.
Stud Bolt Materials
For high-temperature and pressure services, ASTM A193 is the most widely used flange material. Grade B7 and B7M are the most frequently used A193 material grades. For low-temperature services, ASTM A320 Gr L7, L7A, and L7B are used. Other stud bolt materials include the following:
