The distinction between seamless and seamed tubes
If you are comparing different types of steel tubing, you will discover a few interesting details. For example, there are tubes that have a weld seam along their length. Others don’t have this. It is the key distinction between seamless and seamed tube.
The reason why the tubes have this difference is due to the manufacturing procedure. People create seamless tubing using an extrusion procedure. Here, they pierce a hole through a bar to create a hollow cylinder. Afterwards, you roll and stretch the section to the necessary diameter.
Welded or seamed steel tubes begin as flat rectangle pieces of metal. You roll them into cylinders and weld along the join. This leaves a visible weld line along the tube. You can hide this however using heat treatments or other processes to smooth everything out.
Both methods are performed to the highest standards to produce a strong steel tube. This also ensures that the tubes are within tolerances that could apply to their load-bearing capacity and dimensions.
In principle though, seamless tubes eradicate a clear-cut weak point. They are what people prefer for most high-pressure projects. But, the manufacturing procedure is more difficult and the tubes typically come with a higher price. However, the extra strength makes up for it.
The middle ground
There are those who can’t use seamless or ordinary welded tubes though and need an alternative. This is where ERW ones come into play. They act as a middle ground between the two. This process melts the steel’s edges to weld it together. Consequently, the ERW tubing has a smoother weld from the outset. You can then treat this using heat to hide the evidence of its existence.
At the end of the day, ERW tubes are an excellent alternative to the seamless models. They are not 100% seamless. Yet, they do possess advantages over ordinarily welded tubes because there is no added filler metal and a small heat zone.
