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.

The finished pipe is then removed and ready for delivery.
