Definitions
- a centring sleeve 30 Arranged peripherally around the annular part 24 of the hot-air nozzle is a centring sleeve 30 with a gap forming a clearance between the centring sleeve and the annular part 24 dimensioned to receive the open end of the outer tube.
- the centring sleeve 30 shapes the tube end to and maintains it at nominal cross-sectional dimension and centres the outer tube relative to the hot-air nozzle and thus the whole double tube 10.
- the tube materials of the inner tube and the outer tube may be different and thus not have the same thermal activation characteristics.
- the individual (separate) passages 26 and 31 can be adapted in order by empirical trials to overcome any problem caused by different kinds of material.
