What is a Repad?

A pad is a pad is a pad, right? Wrong!  But we're the wear pad people, right?! Well not exactly. Wear pads are what we're more commonly known for, but that's not all that customers request. They send us all sorts of requests and one of the items we get are repads. I wasn't very familiar with these when we first started selling them, but now they're something we do pretty frequent for customers. At this point, you're probably asking what the heck is a repad?

The quick and dirty answer is that a repad, is a reinforcing pad. Well how is that much different than a wear pad? It's massively different. It looks like a doughnut that goes around a piece of pipe where it joins another pipe. These reinforcements are welded onto the piping system where the stress on the system is too high at a junction between pipe, this is called a Stub-in.

Like you, I didn't think these pads were all that complicated, but once I started digging into them, they're apparently a bit more complex and important in the grand scheme of things. First off, they require pipe stress analysis to determine if the weakening from cutting open the pipe and then joining them has created a potential hazard in the piping system. Secondly, it appears they are not the easiest things to draft up and draw once an engineer has decided one is needed. PVEng even has tips and trick on how to use different commands to draw and design repads in pipe stress software.
