This pin finned tube welding machine employs Siemens SINUMERIK802 control system for easy and simple operation. The pin finned tube welding device is generally used to weld the steel pin to the base pipe for boilers. High automatic. the welding equipment is capable of completing pin feeding (2 heads), welding, indexing, base tube feeding, etc.The pin pitch and angle can be adjusted, freely.
Technical Parameters of Pin Finned Tube Welding Machine.
This machine is specifically designed for high-frequency welding cylindrical pins onto the outer surface of base tubes. Its spirally arranged pins (3-8mm in diameter, 5-15mm in height) increase the heat transfer area to 3-8 times that of a plain tube. Its core functions include base tube positioning, pin feeding, high-frequency welding, and finished product inspection. It is compatible with a variety of materials, including carbon steel, chrome steel (0Cr13), and stainless steel (Cr18Ni8).

Studded Finned Tubes Produced by Pin Finned Tube Welding Machine
Pin finned tube welding machine for carbon steel, stainless steel tube & pipe welding featured with high efficiency and reliable.
Pin Finned Tube Welding Machine Produced the Studded Fin Tube
Pin finned tube welding machine is primarily used to manufacture serrated industrial welded studded fin tube. Its core process is high-frequency welding technology. The equipment uses high-frequency current instantaneous heating to achieve a metallurgical bond between the base tube and the fin material, ensuring joint strength and heat transfer efficiency.


Studded Pin Finned Tube Welding Machine
The stud is the core heat transfer element of the stud-finned tube. It is cylindrical or truncated-conical in shape and is metallurgically bonded to the base tube through high-frequency welding.
Diameter Range: 3-8mm (4-6mm is common)
Height Range: 5-15mm (8-12mm is commonly used for heavy oil heating)
