23 Excel Model Features: Easy to Handle Flexible Minimum Cost Time Saving

24 Verification & Comparison
Excel Model Construction Optimization Verification & Comparison

25 Model Importance Material Saving: For a pipe force: Fp=1502 lb;
Current Technique: V=30*16*16=7680 ft^3 Excel Model:minimzed to V=4288 ft^3

26 Model Importance Material Saving: For a pipe force: Fp=1502 lb;
Typical Solution Obtained by Saudi Aramco Engineer: V=30*16*16=7680 ft^3 Excel Model:minimzed to V=4288 ft^3 % Saving: =45%

27 Results Concluded The dimensions for a given force can be obtained using: Model (Solver) Tables Charts Equations

28 Results Concluded Equations: with h1 = 3 ft For W=4H:
H= x B= x0.4072 W = x d= x0.3794 For W=8H: W = x H= x0.3905, B= x d= x0.4162

29 Results Concluded Equations: For x=1000 For W=4H: H= 10.6 B= 6.6
W = d= 6.4

30 Results Concluded Important Notice
The dimensions are exponentially related to the pipe’s force magnitude Approximately Min 40% saving in material
