An angled-line source that is simplified into an equivalent parallel line source if the its standoff distance is equal to or less than the effective length of the line. The calculation uses a point source solution that simplifies methods for an angled line source.
Minimum distance from the pipeline to the nearest explosive charge must be greater than two times outside pipe diameter.
Maximum allowable angle between pipe and explosive line must be less than 90Λ
π ,π΄Β β Distance from the Charge to the Pipeline(ft)
π΅Β β Angle Between Pipe and Grid(deg), convert to Radians =Β π΅(0.0175)
