Abstract
| Small diameter thin-walled pipes, typically with a diameter less than 20 mm and a ratio of outer diameter to wall thickness is 20 or
above, have increasingly become a key value adding factor for a number of industries including medical applications, electronics
and chemical industries. In high-energy physics experiments, thin-walled pipes are needed in tracking detector cooling systems
where the mass of all components needs to be minimised for physics measurement reasons. The pipework must reliably withstand
the cooling fluid operation pressures (of up to 100 bar), but must also be able to be reliably and easily joined within the cooling
system. Suitable standard and/or commercial solutions combining the needed low mass and reliable high-pressure operation are
poorly available. The following review of literature compares the various techniques that exist for the manufacture and joining of
thin-walled pipes, both well-established techniques and novel methods which have potential to increase the use of thin-walled
pipes within industrial cooling systems. Gaps in knowledge have been identified, along with further research directions.
Operational challenges and key considerations which have to be identified when designing a system which uses thin-walled
pipes are also discussed. |
