Nuclear and Power
Fine Tubes has a pedigree of developing tubes for the nuclear industry dating back to the 1970s, when we started supplying nuclear fuel cans to the UK’s first generation of gas cooled reactors. As nuclear power has evolved, so has our expertise and we have manufactured products for agr, pressurized water, light water, heavy water and fast breeder reactor technologies. Today you will find our tubes deployed in plants in the EU, the US, Canada, India and China.
Because nuclear power involves hazardous materials, strict compliance, integrity and precision are absolutely critical. We can control tube dimensions down to a tolerance of just ¼ the diameter of a human hair. Meanwhile, reactor fuel cans using our tubing operate at 650°C non-stop, for five years, without fail. Our 100% reliable components are also used in steam generators, heat exchangers, control and instrumentation units, and more.
Fine Tubes has reached this position in the market by working in partnership with our customers. Our experts will work side-by-side with engineers from design and engineering through testing and certification, and on to manufacture and delivery. Our product integrity is assured from melt to the finished tube.
We not only have the plant capacity to make quality assured tubing compliant with RCC-M, ASMEIII QSC for nuclear programs, but we also have a track record in helping the industry advance by developing new solutions.
