What is a Reinforcement PAD?

Reinforcing Pad or RePAD or RF Pad is a donut-shaped pad that goes around the branch of a branch joint to add strength to the joint. It resembles a round metal washer that has been bent to conform to the curvature of the pipe.With the increase in pipe size, the cost of branch connection fittings increases. Sometimes, such fittings are not readily available as standard pieces. So, it is a standard method to fabricate the tee by cutting a hole in the header and welding the branch in the pipe. But the section where the straight pipe is punctured becomes weak section due to the presence of that hole. So to handle the pressure and reduce the stress concentration in that region the thickness is increased locally in the form of reinforcement pad or RF Pad. Similar situation arises for Pressure Vessel Nozzle Connections. To increase the pressure and load carrying capability of the equipment nozzles, RF Pad are welded. These reinforcement pads provides additional strength and capability to the pipe.

Uses of Reinforcing PAD

1. Normally Reinforcing pads are used at stub-on and stub-in branch connections if required per the line list or if required per the branch chart in the piping material specification. By using reinforcing pads it is not required to strengthen the complete header pipe. Clause 304.3.3 of ASME B 31.3 provides equations to check if any welded piping branch connection requires reinforcement.

2. Support trunnions are provided with reinforcement when specified by piping stress engineers. When supports loads of trunnions are more than the bearing capability of the trunnion, reinforcing pads are welded at the parent pipe and trunnion junction to enhance its load-carrying capability. However please keep in mind that reinforcement on trunnions from elbows is not suggested as standard practice, So it should be avoided to the maximum extent possible. The requirement of reinforcement must be specifically mentioned in the isometric drawing for conveying to the construction team.
