Purpose:
The purpose of this letter is to present the calculated design pressures for the existing Williams 16"
pipeline and the new tie-ins and laterals.
Design:
This design meets the requirements of ASME 831.8.
From Section 84L.1.1:
25t
P =-Pgy
Where:
P = design pressure (psi)
5 = pipe yield strength (psi)
1 = pipe wallthickness (in)
g = pipe outside diameter (in)
F = design factor
E = longitudinaljoint factor
T = temperature derating factor
Resu lts:
Three pipe segments were analyzed using the design pressure formula from ASME 831.8 and the results
are in Table l below.

Calculations:
Segment 1:
Buried Pipeline: Middle Fork - Williams Lateral (New line - X52)
16" x .375 wallAPl 5L X52 PSL2 PEB DRL ERW w/FBE (14-16 mils)
D=15inOD
t = 0.375 in wallthickness
S = 52,000 psi
F = 0.72 Class t, Division 2
E = 1.0 Electric Resistance Welded
T = 1.0 250F or lower
p = (2*S*t)/D'tF'tE*T design pressure (psi)
P = 2*52000*.375/L6*.72=1755.0 psi
Segment 2:
Buried Pipeline: Middle Fork - Williams Lateral (New line - X65)
L6" x.375 wall X55 FBE externally coated pipe
D=16inOD
t = 0.375 in wallthickness
S = 65,000 psi
F = 0.72 Class 1, Division 2
E = 1.0 Electric Resistance Welded
T = L.0 250F or lower
p = (2*S*t)/D*F*E*T design pressure (psi)
P = 2 *55000* .37 5 / L6* .7 2=219?.75 psi
Segment 3:
Buried Pipeline: Williams L5" GV Plant to Greasewood (X52 segments)
t6" x.2L9 wall X52 FBE externally coated pipe
D=15inOD
t = 0.219 in wallthickness
S = 52,000 psi
F = 0.72 Class L, Division 2
E = 1.0 Electric Resistance Welded
T = 1.0 250F or lower
p = (2*S*t)/D*F*E*T design pressure (psi)
P = 2*52000* .219/L6*.72=1024.92 psi
