Summary

D.{John DeLooze - Company Secretary} Introductory (Purpose of Investigation)

Samples of "Superflexit" flexible tubing, said to be suitable for fuel and oil were received for test at R.A.E. from France.

Range of Investigation

Samples of two sizes were received - 16 m.m. and 24 m.m. bore. They were subjected to the following tests :-

(a) Vibration for 232 hours under slight pressure of paraffin.

(b) Hydraulic resistance on 6 ft. lengths.

(c) Temperature by means of oil at 50 lb.per sq.inch pressure and 100°C. for 50 hours.

(d) Bursting pressures at the end of period mentioned in (a).

(e) Chemical tests on the inner lining.

(f) Composition of the tube was examined and the specific weights measured.

(g) End connections were made up and fitted.

Conclusions

(a) Vibration - no leakage of any kind occurred.

(b) Hydraulic resistance - This was about 200 - 300% more than plain copper tube of similar bore for 6 ft. lengths using water.

(c) /
