The âtransformationâ of straight pipe to bent pipe takes place in the heated narrow annular zone which moves continuously along the length of the bend as the bending process advances (Figure 1). The heating of this zone is effected by means of an induction ring (Figure 2).
Budget at completion (BAC): The total planned value (PV or BCWS) at the end of the project. If a project has a Management Reserve (MR), it is typically not included in the BAC, and respectively, in the Performance Measurement Baseline.
By themselves, PVCâs do not present any problem. Bigeminy, Trigeminy, Quadrigeminy, etc. - ventricular bigeminy is the occurrence of a PVC every other beat, trigeminy is every third beat, quadrigeminy every fourth beat. The main point with these types is that the PVCâs are more frequent in these circumstances. They are otherwise little different from PVCâs.
