Product Introduction

The stud tube (also known as the needle tube) adopts a square or hexagonal arrangement and is equally divided into cylindrical needles welded on the surface of the heat exchange tube. The square or hexagonal reinforced heat exchange nail head tube is assembled and welded to form a high-efficiency and energy-saving needle tube heat exchange tube group. Because the nail head tube needle rib is a cantilever structure and has a compact structure, under the impact of the air flow, the needle rib will produce Vibration makes it difficult for soot to accumulate; coupled with the strong turbulent scouring of the flue gas, the heat transfer efficiency of the heat exchange element of the nail head tube is high, and it has a strong self-cleaning ability.
