Structure and manufacture of twisted tube 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 manufacturing process of twisted tube includes:"partial pressure" and "distortion". The tube’s cross section is nearly an ellipse, of which the ratio of long axis and short axis is designed according to the flow velocity in tubes passes and shell passes of heat transfer tubes. When the flow rate in tube pass is low, the ratio of the long axis and short axis shall be increased, or the flow surface shall be reduced in order to increase the flow rate. Enhanced heat transfer principles of twisted tube 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.

Zhejiang Huanchen Super Flux Tube Science Technology Co., Ltd is a private stock enterprise with a registered capital of 13.8 Million RMB and over 10,000 manufacturing coverage. The company is located in Jiaxing City with strong economic growth and advantageous traffic condition.
    The company is one of the leading companies in the related industrial field with good R&D team, well- equipped lab and special intellectual property right.
    The main business scope is series of high efficiency heat transfer tubes and tech consulting service. Main products include high flux tube、twisted tube 、fluted tube,etc. We are targeting on process of heat and mass transfer、high efficient heat transfer、waste heat recovery and material separation. 
    The company insists on the “global standard, tech oriented, high quality and superior service” strategy. Our products has won good reputation in many industrial fields such as  oil & petrol, mineral oil, air separation and refine chemical industrys, etc.
