How to make a choice between Welded Steel Pipe and Seamless Steel Pipe?

To make a choice for a project between different types of steel pipe or tube seems always a headache issue among most of end-users in life.

In the steel market, we can often find two major categories of pipe: welded steel pipe and seamless steel pipe. There are many customers have asked us about how to make a choice between these two types of pipe. Here we will provide you with more information in detail.

Obviously, the difference in the basic manufacturing method is from their names. Seamless pipe is extruded and drawn from a billet while welded pipe is produced from a strip that is roll formed and welded to produce a tube. Generally speaking, there is a difference in the steel pipe prices between these two types of pipe due to different manufacturing methods in a mill.

Although the working pressure of welded pipe is 20% less than that for a similar seamless pipe, working pressure is not the determining factor for choosing seamless pipe over welded pipe for analyzer sample lines. The difference in potential impurities, which reduce the corrosion resistance of the finished pipe, is why seamless pipe is specified.

As we have talked more about the advantages of seamless steel pipe in use previously, today we would like to talk more as follows.

Advantages Of Welded

Welded pipes are typically more cost effective than their seamless equivalents.

Welded pipes are usually more readily available than seamless. The longer lead time required for seamless pipes can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate.

The wall thickness of welded pipes is generally more consistent than that of seamless pipes.

The internal surface of welded tubes can be checked before manufacturing, which isn’t possible with seamless.

Advantages Of Seamless

The main perceived advantage of seamless pipes is that they don’t have a weld seam. Traditionally, the seam of welded pipes has been viewed as a weak spot, vulnerable to failure and corrosion. For many years, this fear was probably justified. However, in recent years improvements in the manufacturing process for welded steel pipes and other welded pipes have boosted the strength and performance of the weld seam to levels indistinguishable from that of the rest of the pipe.

Seamless pipes provide peace of mind. Although there should be no issues with the seams of welded pipes supplied by reputable manufacturers, seamless pipes prevent any possibility of a weak seam.

Seamless pipes have better quality, or roundness, than welded pipes.

As it is well known, everything has two sides. Each type of steel pipe also has their own merits and drawbacks. What really matters to you is to select the proper type of products for your project as per the specific requirements of the practical applications. On the other hand, it is also important for end users to take a cost budget into consideration in advance.
