The most common Reinforcing Pads accommodate an outlet at a 45° or 90° angle. The setting is important as the width of the template will change depending Reinforcing pads (repads, branch connection pads, lateral/nozzle reinforcing pads) strengthen locations where pipes intersect. Attention! calculations based on the pressure-area methodology, the question arises whether a reinforcement pad efficiency factor should be included to compensate for the gap between the reinforcing pad and the vessel wall. “A branch connection is the joining of two intersecting pieces of pipe that split a process flow. Typically used when the branch size is less than half of the run size, WeldFit also offers partial reinforcing saddles. The welds that are present in the nozzle will also participate in the reinforcement area. If there were any meaningful safety concerns with the split re-pad joint, the committee would have said "yes". The gap is the reason that the combination of pad and vessel wall cannot be regarded as completely integral, so that the Full-Encirclement Reinforcing Saddles are used to provide reinforcement for branch outlets when the code dictates further strength may be required. 1 (click for larger image) Our reinforcing saddles are manufactured in: Carbon A234 WPB; A234 WPC; Low Temp A420 WPL-6 According to the size of the main pipeline, the THREADED FITTING needs an additional reinforcement like a: Weldolet or Pad.
