Higher heat transfer coefficient stainless steel,carbon steel,
copper twisted fin tubes
What is twisted tube?
Twisted tube is a kind of enhanced heat transfer tubes and its
structure feature is that each cross section on is oval, when
assembled heat exchanger they can be mixed bundles. That is, the
mixture of twisted tube and plain tube, and also can be a pure
twisted tube bundles.
Seamless steel twisted tubes used for producing heat exchangers are
complet one tube without any joints. And the heat transfer
coefficient of the twisted tubes is 40% higher than the plain
tubes, while the pressure drop is almost same.
Tubes are firmly supported while allowing a well-distributed
longitudinal flow along the tubes. While stresses and other
mechanical considerations are similar to conventional baffled heat
exchangers, the twisted tube bundles provide absolute resistance to
vibration. Repair is the same or similar as for conventional heat
Tubes can be made in a variety of materials: carbon steel ,
stainless steel ,monel, brass, nickel etc.
