How do you connect metal pipes?

There are several methods to connect metal pipes, including threading, using pipe fittings, and using Klemp pipe fittings.

Methods for Connecting Metal Pipes

Here's a breakdown of common methods:

Threading: This involves cutting threads into the ends of the pipes so they can screw together with a threaded fitting.
Pipe Fittings: These are separate components that join pipes together. Common examples include:
- Elbows (for changing direction)
- Tees (for creating branches)
- Couplings (for joining straight lengths)
- Unions (for easy disconnection later)
Klemp Pipe Fittings: These fittings offer a simple, weld-free, and thread-free way to connect pipes tightly. According to the reference, using Klemp pipe fittings is the easiest way to connect pipes, as it provides a tight connection without requiring threading or welding.

Method	Advantages	Disadvantages
Threading	Strong, reliable connection.	Requires specialized tools for threading; can weaken pipe at the threads.
Pipe Fittings	Versatile, can be used for a variety of applications.	Requires sealant to prevent leaks; some fittings may reduce flow rate.
Klemp Pipe Fittings	Easy to install, requires no threading or welding, provides a tight connection, reusable. According to the reference, it is the easiest.	Can be more expensive than other methods; may not be suitable for high-pressure applications depending on the specific fitting.
