Carbon Steel R Pad 90 Sch80-Sch40 ASTM A420 WPL6 36"x16" Pipe Fitting

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.
