Description
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. With our state-of-the-art machinery and high-quality materials, we produce rolled & welded pipe that meet your exact application needs.
Union Steel can roll both thick and thin plate into large and small diameter tube or pipe. With CNC control we can offer industry leading repeatability from the first section to the last and our operators can produce cones, transition pieces and lobsterback sections as required.
Rolled and Welded Steel Pipe Features
- Carbon steel or stainless-steel fabricated products
- Variety of thicknesses
- Variety of diameters
- Variety of heights or lengths
- Pipe coating protects our pipes from damage over time
