Detailed Description:
The structure feature of twisted tube is that every cross section is an oval, when when assembled into heat exchangers they exchanger they can be mixed bundles (that is, the mix of twisted tubes and bare tubes), and also can be a pure twisted tube bundle.
The unique structure of twisted tube can make the flow in tube pass and shell pass in the spiral motion at the same time, by this way it enhanced the turbulent intensity. The heat transfer coefficient of the twisted tube is 40% higher than the normal one, but the pressure drop is almost the same.
As twisted tube has been fast developed and improved in recent years, it is much more reliable and effective, which can almost be used in all kinds of shell and tube heat exchangers. More than 1000 twisted tube heat exchangers have been used since 1984, which can be used in gas-gas, liquid-liquid and liquid-gas heat transfer process, including chemistry, petroleum, food, papermaking, electric power, metallurgy, mining, and urban heating industries.
