What is Union
A pipe union a Forged Steel Pipe Fitting is a secure and semi-permanent connection between two pipes. Most pipe unions consist of two pipes connected together via a third piece. All three are threaded to make a firm connection. While unions are similar to couplings, they are generally easier to take apart and allow pipes of different metals to come together safely.
This joining method is common in household and commercial pipe systems. At first glance, a Pipe Coupling and a pipe union seem very similar. They both connect two pipes together using a male and female threading system. The main difference between the systems comes from the actual method of joining. Two coupled pipes screw together directly, one inside the other. To take the pipes apart, every pipe that connects to the coupled pipe needs to turn. In a full pipe system, this would mean the entire system needs to come apart to remove one pipe.
Pipe Fitting unions are common in all sorts of basic plumbing situations. Houses and businesses typically use these pipe systems because they are easy to maintain and repair. On the downside, since they have more threaded parts, they are more likely to leak than standard couplings. As a result, dangerous or high-pressure liquids are often moved through pipes joined via other methods.
