If you’re using a seamless or welded pipe, then there are sometimes differences between the two. A seamless pipe will have a smooth surface, while a welded pipe has small bumps on it. The smooth surface of a seamless pipe makes it more resistant to corrosion and air permeation, so more of your fluid can flow through a seamless pipe than a welded one. A seamless pipe has been molded together without any seams. Welded pipes are those which have been welded at each joint and where the welding metal goes through the other side and melts to form a seam.

After knowing the difference between the two, the real question that one often asks is as to why there is such a difference. To answer this question we have given you a glimpse of the same 

Why is there a Difference Between a Seamless and Welded Pipe?

Seamless pipes are made of only one piece of metal. Welded pipes are also made of two pieces, but they are joined together with a weld. The seam is what can lead to leaks if it becomes worn out, so the welded pipe is more durable and longer-lasting than its seamless counterpart. A seam is a groove that is cut into the surface of a pipe or tube and is typically used for joining two pieces of pipe or measuring the distance between different points. Welding joins metal to metal by melting the parts together. A seamless pipe does not have any welding seams because it was made using a single piece of metal and therefore doesn’t need to be joined with another piece. A seamless pipe is a pipe that has been welded using a single process and without any weld joints. The metal surface is smooth and uninterrupted and the outside diameter of the pipe is not visible. A welder, when welding a seamless pipe, can use either electric or gas-powered torches to melt the metal in one operation. Welding a seamless pipe also gives it two different types of walls: inside and outside walls that are made up of different thicknesses.

How to Identify the Difference Between a Seamless and Welded Pipe

The difference between a seamless and a welded pipe is how they were made. A seamless pipe is created when a steel tube is rolled into a round shape with no ends left sticking out, while a welded pipe has an open joint at one end and the other end being finished by welding the pieces together. Welding is created to help with corrosion and contamination. There is a stainless steel sleeve added around the inner pipe for this reason. The smooth outer surface of a seamless pipe can usually be found in use on water and steam lines. Welded pipe requires more maintenance than seamless pipe because the welding process creates joints that require periodic checking. The seamless pipe can often be found in thinner wall thicknesses, which means it is easier to install and repair.

Are There Any Pros or Cons of Having Pipes Welded vs Seamed?

A seamless pipe will have no sign of a seam. They have been installed by welding to create a seal on the inside and outside of the pipe. A welded pipe will have a visible tell-tale sign of a seam running along its circumference. Seamless pipes are more likely to last longer than welded pipes because they don’t have these cracks in them from being handled too often. Pipe welding is a process that uses high pressure, friction, or heat to join pieces of metal together so they are permanently bonded. It is the most common type of fabrication used in construction. Pipe seaming, on the other hand, is a manufacturing process that involves manipulating the inside diameter to create an interference fit with the pieces being joined.

Pipe Selection, Welded or Seamless? 

Regardless of the way that further developed manufacturing strategies for continuous-time can convey welded pipes comparable to seamless pipes, still, the consistent pipes are liked in a limit of the cases. Regardless, for gigantic size directing applications (>24 inch NPS) welded pipes are for the most part favored due to less expense. Close by cost, various limits like estimation to thickness extent, openness, disintegration resistance, etc are considered for pipe decision.

Conclusion

There are two types of pipes that are welded together. One is called a seamless pipe and one is called a welded. A seamless pipe has no seams in the pipe at all, which makes it more durable than the welded pipe. Seamless pipes are more commonly used for water piping systems because they do not require joints or bolts to stay together, making them easier to use and less costly for installation. This article discusses what seamless and welded pipes are. A seamless pipe allows a liquid to flow through it, while a welded pipe has a seam in the metal.
