I found a chart with recommended torque values for ASTM A193 B7 bolts for use with carbon steel flanges but how are the torque values affected when using the same bolts with CuNi flanges? It seems like different flange materials would require different amounts of clamp load.
By applying an axial force of 10,426 lb. to the pipeline in the direction away from the tie-in, the max axial stress created is 2,305 lb/in^2 and the max code stress created is 38,942 lb/in^2. The pipeline has an allowable stress of 46,071 lb/in^2. What should the PBSJ be set at?
I have a piping configuration where a feeder pipline (4" S/80 API 5L Gr. B) ties into a receiving pipeline subsea (as shown on the attached). The feeder pipeline travels parallel to the receiving pipeline just before it 90's into the receiving pipeline. Just before the feeder pipeline travels...
