Below are the list of validation checks we have incorporated in API 1102 – Pipeline Crossing Railroad (Gas and Liquid)
| Parameter | Validation Check |
|---|---|
| Operating Pressure | “Numerical value for operating pressure should be between 0 – 5000 [psi]” |
| Pipe Depth | “Numerical value for pipe depth should be between 6 – 14 [ft]” |
| Bored Diameter | “Numerical value for bored diameter should be between D and D + 6 [in]” |
| Operating Temperature | “Numerical value for operating temperature should be between -20 and 450 [deg F]” |
| SMYS | “Numerical value for SMYS should be between 24,000 – 80,000 [psi]” |
| Outside Diameter | “Numerical value for outside pipe diameter should be between 2 – 42 [in]” |
| Wall Thickness | “Numerical value for pipe wall thickness/outside pipe diameter ratio (tw/D) should be between 0.01 and 0.08!” |
| Wall Thickness | “Pipe wall thickness can not be less then 2.03 [mm] for pipes with outside diameter less or equal 185.75 [mm]” |
| Wall Thickness | “Maximum pipe wall thickness can not be greater than 39.7 [mm] for pipes with outside diameter equal or greater then 355.6 [mm]” |
| Wall Thickness | “Insufficient pipe wall thickness for given operating conditions” |
| Wall Thickness | “In accordance with CFR 192 minimum required wall thickness should be XX inch and currently wall thickness is ** inch” |
| Installation Temperature | “Numerical value for Installation temperature should be between -20 and 450 [deg F]” |
