ASTM A335 P11 Alloy Steel Studded Pin Finned Tube / Pipe For Heat Exchanger
Studded Fin Tube/ Studded Pin Finned Tubes are tubes used in heat exchangers that have protruding studs and fins on their surface. These help to increase the surface area of the tubes, which in turn improves the heat transfer efficiency. These tubes are commonly used in high temperature and high pressure applications, such as in the chemical, petroleum, and natural gas industries. The studs can be made of a variety of materials, including carbon steel, stainless steel, and other alloys. The fins can also be made from different materials, such as aluminum or copper. Studded Pin Finned Tubes are designed to withstand harsh operating conditions and are a reliable choice for heat transfer applications.

Advantages of Studded Tubes
Studded Pin Finned Tubes are often chosen for heat transfer applications because they offer several advantages over other types of tubes. The studs and fins on the surface of the tubes increase the surface area, which improves heat transfer efficiency. This means that a smaller heat exchanger can be used to achieve the same level of heat transfer as a larger one, resulting in cost savings. Additionally, the studs and fins help to disrupt laminar flow and promote turbulent flow, which also enhances heat transfer. Studded Pin Finned Tubes are also durable and can withstand harsh operating conditions, making them a reliable choice for high temperature and high pressure applications.
1. As the pin rib of the studded tubes is a cantilever structure with a compact structure, the pin rib will vibrate under the impact of the air flow, making it difficult to accumulate soot.
2. due to the strong turbulent flushing of flue gas, the studded tubes heat exchange element has high heat transfer efficiency and strong self ash removal capability.
