What is the Standard for Pipe Flanges?

I. Introduction

A. Definition and Importance of Pipe Flanges

1. What Are Pipe Flanges?
   • Picture this: You’ve got pipes, valves, and all sorts of plumbing gear in a piping system. Now, how do you connect them seamlessly? That’s where pipe flanges strut onto the stage. These are like the connectors that bring everything together. They make assembling and disassembling a breeze, whether you’re fixing a leak or tweaking the system for better performance.
2. Significance in Piping Systems
   • Now, why are these flanges such a big deal? Well, think of them as the glue holding your piping system together. Their job is not just to connect pipes; they’re the MVPs ensuring smooth fluid or gas flow. But that’s not all – they also make your life easier when it’s time for maintenance or repairs. Imagine not having to dismantle the entire system just to fix a small issue. That’s the magic of pipe flanges.
