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. Rolled & Welded pipe is made from sections of plate rolled into cans. The seam of the can is welded and then the individual cans are welded together to make the finished pipe.

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 rolled and 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.

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:

Rolled & Welded Pipe Sizes:

  • Diameters up to 204 inches
  • 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.

Applications of Rolled & Welded Steel Pipe

Steel pipe offers mechanical and physical characteristics that make it one of the most versatile construction products available. As a structural element, steel pipe remains unrivaled when compared to alternate materials. The flexibility offered by the manufacturing process, quality control and low production cost positions steel pipe to be the new shape of steel in many industries.

  • Bearing Piles: Driven steel piles are a very efficient way to carry loads from structures and one of the most tested elements in the construction industry. Pipe piles offer several advantages over other types of driven piles.
  • Drilled Shaft Casing: Pipe casing, temporary or permanent, is often required during the construction of drilled shafts. The casing is used to hold the hole open while the reinforcement cage and concrete are installed.
  • Structural Sections: The symmetry of pipe gives it the same bending strength, in any direction, which makes it an excellent product for the resistance of buckling.
  • Combination Walls: Large diameter pipes have high bending strengths and are often used in combination sheet pile walls.
  • Threaded Micropile Casing: Micropiles are small diameter, bored cast-in-place piles, with most of the applied load being resisted by steel reinforcement.
  • Mining: Personnel, equipment and air shafts are all integral parts of the mine. Vertical pipe sections are often used to construct the shafts.
  • Sign Poles, Towers, & Transmission Lines: Sign poles and towers are designed to resist large bending loads at the base of the structure. The availability and wide variety of thicknesses of large diameter pipe allow designers to pick the exact size needed to handle their particular project.
  • Jacked & Bored: The placement of underground utilities is often done with jacked and bored pipe.
  • Line Pipe: Welded steel pipe provides an effective method for transporting liquids, air, and gas. Steel pipe is pound per pound stronger than any other type of line pipe.

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


During this last step of the manufacturing process, cans are fit together using the submerged arc weld (SAW) process, according to customer requirements for specific lengths.

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.

finished pipe


The finished pipe is then removed and ready for delivery.
