There is a common belief in the tubing industry that seamless tubes are better in terms of life expectancy. This is if you compare to ERW. Often people believe that the weld seam of ERW tubes is a real weak point. What we are going to do in this post is provide a rundown of seamless boiler and ERW tubes. By doing this, we hope to reveal the truths about the industry assumptions that plague your purchasing decisions.
ERW tube manufacturing
Prior to diving into it our topic, we need to say that many changes have taken place in the creation of ERW tubes. These days, with the manufacturing, process, and control technology advancements, we can achieve zero defect weld consistency. This was not the case a few decades ago. In truth, specification bodies tend to treat seamless and ERW tubes alike today.
Another frequently occurring allegation is that ERW tubing corrodes as easily as the weld. However, the fact of the matter is if you don’t employ any exterior electrodes, it destroys any chance of differential corrosion. In modern times, ERW tubes get normalised in the last phases to gain a homogenised microstructure. This is to rule out any chance of corrosion. For the best ERW steel tubes West Midlands provides, give us a call today.
Exterior defects
Seamless tubes are characterised by exterior defects of numerous lengths. ERW tube tends to have fewer issues here. This is thanks to the advent of contemporary manufacturing practices. They improve the quality of both the outer and inner surface.
Thicknesses
For the thickness variation between the two models, seamless designs typically get characterised by huge differences. ERW tubes on the other hand have far less variation. Thus, the heat transfer might not be uniform with seamless. Additionally, and most importantly, for the same tonnage and nominal thickness, you can produce more lengths of ERW tubing.
Lengths and affordability
ERW tube is available in longer lengths if you compare to seamless boiler tubes. They are also more affordable too. As such, it is often sensible to pick modern ERW tubing over their seamless counterparts. You just have to take the pressure into account.
