Fin Tube

Fin tube is available in fin counts of 30, 32, 36 and 43 fins per inch (FPI)

Fin tube provides 3 times the external surface area of bare tube.

Fin surface is smooth without burrs and folds, which makes it difficult for fouling and easy for cleaning, low flowing resistance.

The Laser Welded Finned Tube is a highly efficient and durable heat exchange component widely used in petrochemical plants, power stations, and air-cooling systems. Using advanced laser welding technology, the fins are precisely bonded to the tube surface without filler materials, ensuring excellent thermal contact and mechanical strength. This process eliminates thermal resistance caused by conventional welding, significantly improving heat transfer performance. The Laser Welded Finned Tube offers outstanding corrosion resistance, superior bonding quality, and a longer service life even under extreme temperature and pressure conditions. Compared with traditional high-frequency welded finned tubes, the Laser Welded Finned Tube provides higher energy efficiency, lower maintenance cost, and more stable operation. It is the preferred solution for modern heat transfer equipment that demands precision, performance, and reliability.

Used in boilers, furnaces and fired heaters. A continuous fin is attached to the base tube by high frequency electric resistance welding in order to give an efficient and thermally reliable bond.
