ASTM A213 TP347H High Frequency Welding Fin Tube With SS409 11Cr Fin In Fired Heater
We have own Fin Tube manufacturer factory. Our factory has more than 50 production lines. Our factory adopts the method of high frequency current, which can quickly complete the welding, and the production efficiency is significantly improved. At the same time, the high-frequency welding technology can ensure that the weld is uniform and high strength, and the physical and chemical properties of the welded joint are better than that of ordinary welding. The high frequency welding heating is rapid and the heat affected zone is small, which reduces the deformation and stress concentration of the material and helps to maintain the overall performance of the tube.
