A new highly efficient heat exchanger tube which can replace the tube array. It has the characteristics of high thermal coeffiaxis of pipe body changes periodically, medium in the pipe maks eddying and it increases coefficient of heat transfer highly. Corrugated tube expands not easy to make fouling. The corrugated tube has also the capacity of self-thermal stress of tube plate. The pass will never burst and leak out, it makes heat exchanger safe and durable. The production capacity of our compny comes to 30 tons per day. In addition, our company can customize different specifications of corrugated tube.
