Applying high frequency induction heating principle the fin tube is made by high frequency welling the steel band spirally and longitudinally on the outside of the tube.The main applications of the fin tube are heating,drying and cooling in the field of oil, chemical,boiler,power station, metallurgy,light textile,food,coach,building materials and machinery etc.The features of the radiator made by fin tube are high welding seam strength,good metal joint surface,low heat resistance, high radiation efficiency, small volume,compact structure and economizing materials etc.
  A complete set of production equipment for spiral of longitudinal fin tube made by our company has the advantages of advanced technique,reliable performance and easy operation.The high frequency induction heating equipment is designed and made for welding fin tube,which guarantees an over 90% weld efficiency especially stainless steel and alloy steel fin tube,higher welding strength and fine-looking externals.We are engaged in designing and making 200Kw and 300Kw single loop high frequency induction heating equipment for welding fin tube without competition.Our product are used by well-know enterprises in the oil, chemical and boiler radiating pipe trades. The high frequency equipment made by our company uses SCR voltage adjustment device controlled by microcomputer.The multiple protective devices and the failure blinking function of the equipment make the maintenance very convenient.
  Spiral winding and welding device is a national patented product that fills a national bland and makes great contribution to the development of the high frequency fin tube trades.Using the similar and advanced equipment of other countries for reference we developed a new generation of high frequency spiral winding and welding device which takes the lead level in China. Our company is the only one to make it. The production efficiency of the new generation is more than twice as high as the old one and the rate of the welding finished products,welding strength and quality have remarkable increase.
