NUMERICALS ON THIN PRESSURE
VESSELS
By: Praveen Kadian
A steel tube having a bore of 10 cm, wall
thickness 1.5 mm is plugged at each end to
form a closed cylinder with internal length of
300 mm. The tube is completely filled with oil
and is subjected to a compressive load of 60
KN. Determine:
a) Pressure produced on oil
b) Resulting circumferential stress in tube.
Koil= 2800 N/mm2, Es= 210 Gpa, v= 0.28
Q. A steel pipe 30 cm in dia and 6 mm thick is
subjected to a pressure of 2.8 Mpa. Estimate
the hoop stress in the pipe under this pressure
and also when wound, before stressing with
wire 2.5 mm dia, carrying a tension of 70 Mpa.
What is the stress in the wire when pipe is
under pressure?
Es=210 Gpa, vs= 0.25
