Píopa Studded

Studded pipes represent a significant advancement in heat transfer technology. These pipes feature studs that are welded along the complete length of the outer surface of a metal pipe. Their purpose is to enhance heat transfer efficiency in diverse settings, ranging from power generation to petrochemical processing. Studded pipes serve as integral components in various industrial applications.

The base pipe in our studded pipes is typically fabricated from low carbon steel or alloy steel, including options such as P3, P5, P9, P11, and more. The studs, on the other hand, are commonly made of mild steel or can be tailored to meet specific customer preferences. Our studded pipes come in various dimensions and can be personalized to match individual customer requirements.

The steel studs are affixed to the pipe using automatic resistance welding, resulting in the creation of superior forge welds. This welding procedure allows for the pairing of various stud and pipe grades, encompassing carbon, low alloy, stainless steels, and high nickel alloys. Following the studding process, alloy steel pipes undergo stress-relief treatment in accordance with the pertinent specifications corresponding to the steel's class and grade.

Due to their relatively straightforward cleaning process, studded pipes, also known as nail head pipes, find utility in furnaces and fired heaters as a substitute for high-frequency welded finned pipes in situations where the process application is prone to substantial fouling on the external surface.

An electric current is applied by connecting it to the stud and pipe, and the resistance within this circuit generates the required heat for welding. The highest resistance, and consequently the maximum heating, occurs at the point where the stud interfaces with the pipe. Various types of tooling are used to exert pressure, forging the stud and the pipe together at this region of maximum heating. These resistance welding processes result in a robust metallurgical bond between the stud and the pipe while minimizing the heat-affected zone (HAZ) within the pipe. The application of pressure to forge the fin and the pipe together helps reduce the heat input necessary for welding. This product is primarily employed in fired heaters operating under very high pressure and temperature conditions, mainly within petroleum refineries.

Achieves a welding connection success rate exceeding 90 percent.
