Answer


Given


  • Internal pressure of pressure vessel = 2 MPa

  • Internal diameter of pressure vessel = 250 mm

  • Material of cylinder = SAE1020



Calculations

The formula for calculating the thickness of the cylinder is:

t = (P * D) / (2 * S * E + 0.8 * P)


  • t = thickness of the cylinder

  • P = internal pressure

  • D = internal diameter

  • S = allowable stress of material (SAE1020) at operating temperature

  • E = weld joint efficiency (assumed to be 1 for seamless cylinder)



From the material specification, the allowable stress of SAE1020 at operating temperature can be found to be 117 MPa.

Substituting the given values in the formula, we get:

t = (2 * 250) / (2 * 117 + 0.8 * 2) = 3.17 mm


Answer

Therefore, the thickness of the cylinder is 3mm.
