Fig. 3. The use of a plasma torch on the Ruby made it easy for workers to gouge out excess metal.


Fig. 4. In the past, pipe line builders needing to gouge out excess metal had to rely on hand grinding. The process was lengthy – typically taking at least 45 minutes for each small area – and dangerous with flying debris causing an average of one serious eye injury per day.


a pipe beveller, speeds up the process of cutting pipe for bends and preparing ends of pipe sections for fitting. With a recommended 0.75-in cutting capacity, the system can run at full capacity off of a 15kW engine-drive generator or at lower amperage off of a 12kW engine drive. Tese cuts were traditionally done with oxyfuel, but the faster cut speeds of plasma reduce the amount of time the tie-in crews spend standing around waiting for the pipe to be prepped. Kevin Berryman, the tie-in foreman for Associated,


has also found that the cut quality of plasma has reduced or eliminated the need for grinding the weld area after the cut—another time savings. Better cut quality and smoother cuts results in easier ‘fit ups’ of the pipe, which in turn results in better welds and fewer field repairs needed. “Plasma is all about time and efficiency in our line of work,” says Berryman. ●
