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.

Mechanical characteristics:

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 exchangers.

Material: 

Tubes can be made in a variety of materials: carbon steel , stainless steel ,monel, brass, nickel etc.
