Description
Our H-gilled boiler fin tube welding machine is developed for manufacturing fin tube composed of single or twin pipes. The fin tube is widely used on the boilers. This fin tube welder consists of push trolley, pneumatic system, welding unit, and support frame.

Controlled by PLC, the H-gilled boiler fin tube welding machine offers semi-automatic production. The production process includes manual steel pipe feeding, manual fin tube unloading, manual fin loading, and automatic fin delivering. The fin spacing and length can be set up on the PLC. Importantly, the fin spacing for one tube can be varied.
