A steam boiler, 1.2 meter in diameter, generates steam at a gauge pressure of 0.7 N/mm2. Assuming the efficiency of the riveted joints as 75%, find the thickness of the shell. Given that ultimate tensile stress = 385 MPa and factor of safety = 5
Added by Tracy N.
Step 1
- Diameter of the steam boiler (D) = 1.2 meters - Gauge pressure (P) = 0.7 N/mm² (Note: 1 N/mm² = 1 MPa) - Efficiency of the riveted joints (η) = 75% or 0.75 - Ultimate tensile stress (σ_t) = 385 MPa - Factor of safety (N) = 5 - The task is to find the thickness Show more…

Design a double riveted double strap butt joint for the longitudinal seam of a boiler shell, 750 mm in diameter, to carry a maximum steam pressure of 1.05 N/mm² gauge. The allowable stresses are: σ = 35 MPa; τ = 28 MPa and ρ = 52.5 MPa. Assume the efficiency of the joint as 75%.

A boiler is constructed of 8 -mm thick steel plates that are fastened together at their ends using a butt joint consisting of two 8 -mm cover plates and rivets having a diameter of $10 \mathrm{mm}$ and spaced $50 \mathrm{mm}$ apart as shown. If the steam pressure in the boiler is 1.35 MPa, determine (a) the circumferential stress in the boiler's plate apart from the seam, (b) the circumferential stress in the outer cover plate along the rivet line $a-a,$ and (c) the shear stress in the rivets.
