2. ¿Qué es un Spiral Finned Tube Machine 

A spiral finned tube machine wraps fins on a tube to generate a continuous spiral structure. The equipment also produces exact fin geometry to enlarge external area. Owing to this, the finished tube provides superior heat transfer in air-cooled systems.

Boilers, gas coolers, air heaters, power plants, petrochemical equipment, and a host of industrial heat exchangers use spiral finned tubes.

3. Working Steps of Machine

En spiral finned tube machine is composed of the following working steps:

• The operator loads the bare tube into the machine.
• The feeding unit feeds the fin strip to the forming system.
• The forming system forms the spiral fin shape.
• The machine attaches the fin to the tube by welding or pressure.
• The cutting system cuts the fin at a preset length.
• The finished tube leaves the machine for inspection.

Due to the high precision of the machine operation, the tube obtains uniform fin spacing and strong bonding.

4. Main Spiral Finned Tube Machines and Types

1. High-Frequency Welded Spiral Finned Tube Machine

The high-frequency welded spiral finned tube machine welds the steel fins to the tube by high-frequency energy. The process gives strong mechanical bonding.

2. Laser Welded Spiral Finned Tube Machine

The laser welded spiral finned tube machine joins the strip to the tube with a laser. The process is featured with low heat input and strong accuracy.

3. Extruded Spiral Finned Tube Machine

The extruded spiral finned tube machine extrudes the aluminum sleeves into spiral fins. This type gives the excellent corrosion resistance.

4. G-Type Spiral Finning Machine

The G-Type spiral finning machine embeds the fin into the groove of the tube. It features better thermal conductivity.

Differences between the types are mainly in the temperature range they support, the materials they process, and the applications they are applied to.
