Round or square fins

Product Features : 

The outer surface of the double-head electric heating tube is equipped with circular or square fins, and then welded and fixed, bent into different shapes. The fins are round and rectangular in order to better and faster heat dissipation. Used in ovens, ovens, aging room, solar air dry burning. As the core component of electric heating equipment, the performance stability of electric heating tube directly affects the products to be processed ! Air dry burning series electric heating pipe, with flexible structure, safety and environmental protection, good thermal conductivity, long service life, high mechanical strength, convenient installation, safe and reliable. The shape of Annai electric double-head electric heating pipe is straight, U-shaped, L-shaped, W-shaped, fin-shaped and shaped. 

Application areas : 

Water, oil, chemical medium, corrosive acid and alkali solution, hot pressing mold and other liquid and gas heating. It has good adaptability to harsh environment and can also be used for heating and melting of metals with low melting point ( lead, zinc, tin, babbitt alloy ).
