How to Choose Seamless Pipe or Welded Pipe in Construction?

Date:2021-08-26    keywords: seamless pipe vs welded pipe in construction
When undergoing any construction process, it is crucial to have the correct materials. When that project involves any type of piping, someone will have to make a decision between welded and seamless pipes. That decision is not always a straightforward as it appears.

For example, there are many regulations regarding the use of welded pipes. This based on the materials traveling through the pipe and the pressure those materials will travel under. Therefore, it’s important to know about seamless steel pipes before making a decision.

Advantages of Seamless Pipe:
Welded pipes are more vulnerable to failure at the weld location, even if a seam may not be visible. Despite improvements in welding technology, a welded pipe can handle a maximum pressure 20% less than that of a seamless pipe. 

There are other advantages to the seamless pipe. A seamless pipe does not require any weld integrity testing and, in most cases, a heat treatment. That’s because seamless pipes harden during the manufacturing process.It is also possible to substitute a seamless pipe for a welded pipe. Meanwhile, a welded pipe cannot take the place of a seamless pipe due to strong regulations. 

Most importantly, seamless pipes are more resistant to corrosion. They contain fewer impurities and defects related to malleability. These usually arise in the welded portion of a welded pipe.

Advantages of Welded Pipe:
While the seamless pipe has many advantages, the welded pipe (LSAW/ SSAW/ ERW pipe) may have some as well. For example, a welded pipe is less expensive than a seamless one, and they have a shorter procurement lead time.

It is not always necessary to use a seamless pipe, but the oil and pharmaceutical industries often require them. The high temperatures and pressures related to their products make seamless pipes a necessity.

As a result of industry regulations, engineers need to consider the pipe’s manufacturing and grade. Seamless and welded processes cannot manufacture all grades.To meet strict deadlines, an engineer must have a thorough understanding of manufacturing constraints.

Whether a seamless or welded pipe is the right choice for a particular construction project is a complicated decision relying on multiple factors and resources. What the pipe will be transporting is the main consideration.
Seamless pipe may be more costly and difficult to come by, but it is a sturdy and versatile product that could reshape the future of engineering.
