Test Report

Shop test pressure determination for Chamber bounded by BOTTOM HEAD and TOP HEAD based on user defined pressure

Shop test gauge pressure is 5.25 kg/cm2 at 20.00 °C

The shop test is performed with the vessel in the horizontal position.

Notes:(1) The zero degree angular position is assumed to be up, and the test liquid height is assumed to the top-most flange.

The field test condition has not been investigated for the Chamber bounded by BOTTOM HEAD and TOP HEAD.

The test temperature of 20.00 °C is warmer than the minimum recommended temperature of -30.61 °C so the brittle fracture provision ofUG-99(h) has been met.

Vessel Characteristics

Vessel height: 112.9130 ft (34.42 m)Vessel Weight:

Operating, Corroded: 118,486 lb (53,744 kg)

Empty, Corroded: 111,551 lb (50,599 kg)

Vacuum, Corroded: 118,486 lb (53,744 kg)

Period of Vibration Calculation

Fundamental Period, T:

Operating, Corroded: 1.572 sec (f = 0.6 Hz)

Empty, Corroded: 1.500 sec (f = 0.7 Hz)

Vacuum, Corroded: 1.572 sec (f = 0.6 Hz)

The fundamental period of vibration T (above) is calculated using the Rayleigh method of approximation:

T = 2 * PI * Sqr( {Sum(Wi * yi2 )} / {g * Sum(Wi * yi )} ), where

Wi is the weight of the ith lumped mass, andyi is its deflection when the system is treated as a cantilever beam.

Anchor bolt load (operating, corroded + Wind)

P = -0.6*W / N + 48 * M /(N*BC)= -0.6*118,461.7 / 20 + 48 * 886,365.7 /(20*94.25)= 19,016.73 lb (8,625.846 kgf)

Required area per bolt = P / Sb = 1.056506 in2 (6.816157 cm2)

The area provided (1.678 in2) by the specified anchor bolt is adequate.

From table 12.4 for k = 0.3378221:

K1 = 2.359863, K2 = 1.60895

L1 = 15.0093, L2 = 47.69108, L3 =24.71917

Total tensile force on bolting

T = (12*M - 0.6*W *(L1 + L3))/(L2 + L3)= (12*886,365.7 - 0.6*118,461.7 *(15.0093 + 24.71917))/(47.69108 + 24.71917)= 107,893.7 lb (48,939.75 kgf)

Tensile stress in bolts use the larger of fs or bolt preload = 0 psi

fs = T / (ts * (d/2) * K1)= 107,893.7 / (0.1154617 * (92.51968/2) * 2.359863)= 8,559.868 psi (601.8177 kg/cm2)

Total compressive load on foundation

Cc = T + W + Bolt Preload= 107,893.7 + 118,461.7 + 0= 226,355.3 lb (102,673.1 kgf)

Foundation bearing stress

fc = Cc / (((tc - ts) + n*ts)*(d/2)*K2)= 226,355.3 / (((5.51181 - 0.1154617) + 9.2889*0.1154617)*(92.51968/2)*1.60895)= 470.13 psi (33.05325 kg/cm2)

As fc <= 750 psi the base plate width is satisfactory.
