 Composite tube (compound tube) suitable for applications where the conditions outside and inside the tube require material properties that cannot be met by one material only.
The composite tube consists of two different alloys metallurgically bonded together to achieve good thermal transfer properties. One alloy is used to withstand corrosion, while the other often is an approved pressure vessel material. Typical applications for Total Piping Solutions composite tubes are steam boilers with corrosive condtions, such as: - Black liquor recovery boilers (BLRB)
- Syngas coolers
- Waste heat boilers
- Waste-to-energy boilers
Total Piping Solutions composite tube have been installed in more than 400 boiler units worldwide since the 1970s. Contact us for references. Composite tube materials | Total Piping Solutions grade | UNS | ASTM/
