Upgrade with Seamless Steel Pipe

For anyone that’s ever seen a construction site before, we probably all assume that all steel pipe is the same. This is not the case, however. There are quite a few varieties of steel piping used in the construction industry. Kelly Pipe offers an array of quality seamless steel pipe to meet the needs of a variety of clients. Not sure why any one pipe would get a job done better than another? Keep reading for some of the key advantages to using seamless steel.

Better Pressure Ratings

The key to understanding the benefits of seamless steel pipe is to understand the pressure that pipes are typically put under. In welded steel pipes, the welded seam is the most vulnerable to pressure, as it has been fused at this fault line. Seamless steel pipes do not have this seam because they have not been welded, meaning that the pipe is equally strong around its entire circumference. Herein lies seamless steel’s key advantage – it can withstand more pressure. This also means that it’s much easier to determine any pressure calculations since you don’t have to take weld quality into consideration.

Seamless pipe can be more expensive than traditional welded pipes, but the increased pressure-withstanding ability means you can use thinner, lighter pipes, which cuts down on costs overall. Talking to the steel experts at Kelly Pipe can help you make the right choice for your project.


Seamless pipe is a continuous extrusion of alloy, which gives it a round section you can rely on. This makes it incredibly useful for adding fittings or installing pipes. Traditional welded pipe, on the other hand, is wrapped around another form when it’s welded, introducing stress and other variables to the process, meaning it can never be perfectly round.

Greater Strength

Seamless steel pipe has greater strength under loading than welded pipes. When a pipe is filled with materials, it’s crucial that it not burst with the weight. Since seamless pipes don’t have a seam, they’re less likely to leak or falter. This is why they’re so popular in modern applications such as oil rigs, pipelines, offshore rigs and ship building.
