Nucor Skyline

There is only one manufacturer to trust- Nucor Skyline, when it comes to rolled and welded pipe. With our state-of-the-art machinery and high-quality materials, we produce rolled and welded pipe that meet your exact application needs.

Our manufacturing plants are located throughout the region with the ability to serve the needs of private and public projects. Contractors can confidently contact one of our sales representatives to discuss the exact specifications needed for their welded steel pipe. Our team of experts can assist you with ordering the right rolled and welded pipe for your project needs. We ensure on-time delivery to keep you on track for your project completion.

We understand how important it is to trust the steel pipe produced for your application needs, which is why we offer two options for testing our products. We are well equipped to handle in-house testing, and we have partnerships with third parties who can ensure the rolled and welded pipe you ordered meets your exact specifications. 

Proudly made in the USA, our steel pipe can be manufactured to meet the design needs of your public or private project in the following pipe sizes: 

Steel Pipe Sizes:

  • Diameters up to 204 inches (17 feet)
  • Wall thickness up to 2.25 inches

Custom lengths and fabrication services are available to meet the needs of contractors throughout the US. We pride ourselves in creating the pipe you need to complete your project on time, every time. Whether you have a standard request or something that is out of the ordinary, give us a call and we will happily discuss your needs and help you place your order.

Pipe Rolling, Tube Rolling

When it comes to the manufacturing of rolled and welded steel pipe, the process used is pipe rolling (also known as tube rolling). In order to create your welded pipe, we employ a team of engineers and welders to ensure the job is completed right the first time. We employ a widely used process that has a proven record of success and allows us to continually create rolled and welded steel pipe used for public and private projects in various industries.

We begin with the highest quality raw material to ensure we can create a pipe that meets your wall thickness requirements. Once we verify the raw material meets our rigid standards, we place it on a burning table. This table allows the material to be heated to a temperature that is easy to work with during the cutting process. It helps us create cleaner lines and improves our accuracy. We can use both plasma and cutting gases to shape the raw materials into the exact length and width dimensions you provide. It is crucial your dimensions are exactly what you need for your pipe before you start this section of the process. 

After cutting the pipe, the next part of our tube rolling process includes beveling. This creates a sloped edge, which is necessary for preparing the pipe for the next stage of the process. It improves the aesthetic of the pipe and makes it safer for our welders to work with. We value our workers and their safety in our day-to-day operations.

Once beveled, we move to the bending portion of the steel pipe rolling process. We take your cut and beveled pipe and place it on our lengthening rolls. Our roll system allows us to create an evenly rolled pipe. This is crucial for creating a can (also known as a true cylinder).

At this point, we are ready for welding. Our welding process is broken up into two stages to ensure your pipe is perfectly welded together. The first is longitudinal welding, which welds the long seam of the pipe on both the inside and the outside. The final welding step is circumferential welding. Using the submerged arc welded (SAW) process, we fit the cans together to create the specific length you request for your pipe. Whether you need two cans welded together or 15, we offer many pipe sizes, custom lengths, and fabrication services that will provide you with the steel pipe you need for your project.

Before we say the pipe is ready for shipment, we conduct our quality control testing. We can test on-site and/or at a third party. If necessary, we even offer ultrasonic testing to prove that both welding processes were completed correctly and do not have any defects. Once we know from our QT and/or UT tests that the pipe is manufactured correctly, your pipe is ready for shipment. We remove the pipe from the manufacturing facility and send it to your job site. Our pipe is always fastened securely to ensure it is not damaged during shipment.

Our pipe rolling/tube rolling process is perfect for private and public contractors who need rolled and welded pipe for their projects. We can manufacture pipe to your exact wall thickness, length, and material specifications. Contact us today to get started!

Manufacturing Process

Rolled & welded pipe is one of the oldest processes of manufacturing steel pipe. This manufacturing process is utilized when the pipe wall thickness exceeds the capabilities of the high-frequency electric resistance weld (ERW) pipe and spiralweld pipe manufacturing processes.



The raw material – pieces of flat steel plate – is received into our manufacturing plant.



A single flat sheet of steel plate is cut on a burning table using plasma or cutting gases. This plate is cut according to the required width and length for each individual can that will form the final product.



After the plate is cut, it is transferred to the beveling station where the plate edges are beveled and prepped for welding.



After beveling, the plate is transferred to the bending rolls. Nucor Skyline uses a 4-roll system to produce a true cylinder, also referred to as a can.



The can is then staged for longitudinal welding (Long Seam). During this process, the seam between the two plates is welded on both the inside and outside.

circumfirential welding


According to customer requirements for specific lengths and pipe sizes during this last step of the manufacturing process, cans are fit together using the submerged arc weld (SAW) process.

quality control


Once the welding is complete, the finished pipe is visually inspected by Quality Control (QC) and, if required, Ultrasonic (UT) testing is performed to ensure the weld is defect-free.

The finished pipe is then removed and ready for delivery.
