Welded Studded Fin Tube | Studded Tube for Heat Exchange
The welded studded fin tube heat exchange enhancement element is a series of cylindrical welded on the surface of the steel tube by a pin tube automatic welding machine. Its characteristics are:
1. Square circumference is evenly divided and welded;
2. Hexagonal circumference is evenly divided and welded.
Compared with the traditional pin tube manufacturing process, the square and hexagonal pin tube heat exchange enhancement elements are welded to avoid the phenomenon of welding pins falling off after forced stretching by tooling after welding, making the pin tube welding more firm and the welding pins not easy to fall off.
The pin tube welding pins, diameter, length, longitudinal spacing, circumferential welding pin number and welding pin inclination are all factors that affect the heat transfer of the pin tube, so they need to be systematically considered to be more practical. The square and hexagonal circumferences are equally divided to arrange welding and pin-shaped tubes, which have a larger expansion surface. The pin-shaped tube has a disturbing effect on the fluid, which can significantly increase the heat transfer coefficient. It is suitable for the occasions of enhanced heat transfer of high-viscosity oil products, heavy oil and other media.
Welded studded fin tube is a common pipe material, widely used in construction, chemical, petroleum and other industries. Its structural characteristics are mainly reflected in the two parts of the pipe body and the nail head. The pipe body is usually made of materials such as metal or plastic, and has a certain strength and pressure resistance to ensure stability and safety when conveying fluids. The nail head is a raised part formed by welding, casting or machining at a specific position of the pipe body. Its shape is similar to the head of a nail, hence the name.
The functions of the welded studded fin tube are mainly reflected in the following aspects:
1. Connection and fixation: The existence of the nail head makes it easier to fix the pipe with other structural parts during installation, improving installation efficiency and reliability.
2. Withstand pressure: The body design of the Welded studded fin tube can withstand a certain internal pressure to ensure that it will not break or deform when conveying fluid.
3. Anti-vibration and shock absorption: The existence of the nail head can absorb and disperse the vibration caused by fluid flow or external impact to a certain extent, reducing damage to the pipeline system.
4. Easy to maintain: Due to the special structure of the nail head, it is more convenient to disassemble and install when performing pipeline maintenance or replacement.
5. Improve fluid dynamics: The design of the nail head can affect the flow state of the fluid in the tube, reduce fluid resistance, and improve conveying efficiency.
In summary, the Welded studded fin tube not only enhances the physical properties of the pipe through its unique structural design, but also improves its functionality in practical applications, making it one of the indispensable pipes in industrial and civil fields.
