What is the difference between a threaded pipe and a welded pipe?

Difference Between Threaded Pipe and Welded Pipe

In piping systems, threaded pipes and welded pipes are two common types of connections used to join components together. The main difference between a threaded pipe and a welded pipe lies in the method of connection.

Threaded Pipe:

A threaded pipe has threaded ends that allow for easy connection by screwing two pipes together. This type of connection is convenient for applications that require frequent disassembly and reassembly, as the pipes can be easily unscrewed and replaced. However, threaded connections may not be as strong as welded connections and may be susceptible to leaks if not properly sealed.

Welded Pipe:

On the other hand, a welded pipe is joined by welding the ends of two pipes together. Welded connections are known for their strength and durability, making them ideal for high-pressure or high-temperature applications. However, welding requires specialized equipment and skills, making it a more permanent and less flexible option compared to threaded connections.

In summary, the main difference between a threaded pipe and a welded pipe is the method of connection: threaded pipes use screw threads for assembly, while welded pipes are joined by welding the ends together.
