A stud is a fastener that resembles a rod. Along the entire length of which, or only at both ends, an external thread is provided.
Various technological processes can be applied in the production of studs. These include:
– turning;
– milling;
– boring;
– drilling;
– drawing;
– cutting;
– thread rolling;
– grinding;
– thermal and galvanic treatment.
The material of fasteners, design dimensions and other parameters are primarily regulated by GOST and OST.
In the production of studs (diameters from M 12 and up), we use the thread rolling method with a tolerance field of 6g (8g). Thus, this method makes it possible to manufacture GOST and OST flange studs of type A and B.
Description
Studs for pipe flange connections in accordance with GOST and OST are fasteners representing a metal rod with a thread.
SILENA produces studs from heat-resistant, stainless and other alloyed steels.
| Steel | 35, 40Х, 30ХМА, 20ХН3А, 09Г2С, 20Х13, 12Х18Н10Т, 14Х17Н2, 10Х17Н13М2Т, 45Х12Н14В2М, 25Х1МФ, 37Х12Н8Г8МФБ. |
Stud production is carried out in accordance with GOST and OST.
| Standard | GOST 9066-75, GOST 22032-76, 22033-76, 22034-76. And also on GOST: 22035-76, 22036-76, 22037-76, 22038-76, 22039-76, 22040-76, 22041-76, 22042-76, according to OST 26-2040-96 and etc. |
In addition, the plant makes full bore studs and according to the Customer drawings. Metric thread M (dimensions are given in millimeters) is the main thread for threaded products. Thus, threaded rods are produced with increased and normal precision. Precision classes A and B, respectively.
Stud production is carried out as soon as possible. All products are accompanied by quality documents.
Own stud production allows controlling the quality of products. As a result, to maximize the satisfaction of Customers requests.
GOST, OST flange studs are widely used in mechanical engineering, in the chemical and mining industries, in the oil and gas complex, and in construction.
You can also purchase studs according to the ASME standard from us.
In the SILENA company, in addition to studs, you can order nuts according to GOST OST ASME from various grades of steel.
