Calculation of pipe weld equivalent
Thread Content
The welding workload in the equipment area = total length of pipelines × 0.127 (correction factor) × pipeline diameter + (number of elbows × pipeline diameter × 2) + (number of tees × pipeline diameter × 3) + (number of flanges × pipeline diameter) + (number of reducers × pipeline diameter × 2). The welding workload in areas other than the equipment area = number of welds (total length of pipelines / length of each individual pipeline) × pipeline diameter + (number of elbows × pipeline diameter × 2) + (number of tees × pipeline diameter × 3) + (number of flanges × pipeline diameter) + (number of reducers × pipeline diameter × 2). Dear seniors, I would like to ask how the number of welds is calculated in the welding workload of areas other than the equipment area. Is the length of each individual pipeline 6 meters? Thank you all first!
The total length of the pipeline multiplied by 0.127 (the correction factor) should give the average length of 1/0.127 = 7.87.
The pipeline inch diameter is the nominal diameter divided by 25, right? Thank you.
The number of welds in the external pipe gallery is calculated at 60% of the total installations; the numbers for the tank area, utility systems, and production auxiliary facilities can be adjusted appropriately according to the actual conditions of the project.
I’m new to this area, so I might not have explained it clearly to you. What does it mean that the number of welds accounts for 60% of the entire device? I’m currently in contact with the local supervisor who handles orders – how should I calculate the number of welds? Thank you
Welding equivalent of the outer pipe = Calculation method for pipeline welding work in the plant area × 0.6； Ground pipes are not applicable.
