Performance features:
1.The installation is simple and economical. The maximum length of high frequency welding spiral fin tube can reach 6 meters, which reduces the connection points, makes the installation more economical and fast, and reduces the probability of water leakage at the joint.
2.It is easy to maintain, After the installation of high frequency welding spiral fin tube, it is no longer necessary to maintain.
3.High efficiency, high frequency welding spiral finned tube for fin and steel tube winding full contact welding, heat dissipation area is more than 8 times of smooth tube.internal more smooth,internal flow resistance is small.
4.Long service life, high mechanical strength of fin and tube combination, tensile strength of more than 200MPa, both inside and outside of the tube are hot-dip galvanized.
