Differences between threaded And welded pipe fittings

April 26, 2025


Pipes move things like water, air, or gas from one place to another. To make the pipes work, they must be connected strongly and safely. There are two common pipe fittings. One is called threading. That means the ends of the pipes have little ridges that let them screw together, like putting a lid on a jar. Welded pipes are powerful and last long, but they can't be taken apart easily. Welding takes special tools and skills. Threaded fittings are faster and simpler.

Threaded Pipe Fittings & How Do They Work 

Threaded fittings have ends that are shaped like screws. These ends help the fittings twist onto other pipes. You do not need glue or heat to make them work. You just twist and turn the fitting until it is tight. These fittings are suitable for homes, schools, or small shops. They are best for short pipe systems where water pressure is not too high.

Welded Pipe Fittings & Why Are They Strong 

Welded pipe fittings are joined by melting the ends of the pipes. A pipe fitter uses heat and tools to melt the metal. Then, the pipes are joined together to form one strong piece. When the melted parts cool down, they stay stuck together. This makes the pipe very strong and solid. It does not come apart easily. many years. They are perfect for places with hot water or high water pressure.
