Product Description

Product Introduction

This H-type finned tube welding machine is a high-efficiency automatic production line equipped with 3×160KVA intermediate frequency inverter power supply, specialized in welding single and double H-type finned tubes for heat exchange systems. It features automatic fin feeding via a hopper and precise base tube positioning, realizing simultaneous welding of left and right fins with the base tube at the welding position. The welding time per pair is less than 3 seconds, boasting a welding fusion rate over 98% and excellent welding strength (tensile strength >200MPa). Adaptable for tubes of 1-14m in length, 19-56mm in diameter and fins of 2-3mm in thickness, it can weld various material combinations like carbon steel and stainless steel. With high dimensional accuracy and stable performance, the machine produces H-type finned tubes with firm welding, uniform heat transfer and strong structural stability, ideal for waste heat recovery systems of power plant boilers, industrial kilns and marine power units.
