Duplex (Double Layer) Tube TH

Duplex (Double Layer) Tube

Corrosion-resistant steel pipe with sealed different materials.

 Sealed double layer pipes created via the cold draw method are used for varying corrosion conditions. They have a successful track record in the water condensers of furnace power plants; oil refinery plants, petrochemical plants and other heat transfer devices. 

 With the ability to combine with rifle tubes, etc., these pipes can be used to control costs as well as corrosion conditions.

Potential range of manufacturing

In some cases, it may be possible to work outside the potential range of manufacturing. Please feel free to contact us.


The outer-inner surface introduced on this website is an example. Please feel free to contact us regarding possible fabrications.

Options depend on our cold drawn steel tube manufacturing capabilities.

Inner-outer sealing is carried out using cold drawing. This results in extremely high adhesion.
