Rolled and 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. Rolled and welded pipe can be made in diameters of up to 16 feet and over 2.0 inches in thickness.

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 ERW and spiralweld manufacturing processes.

plate

PLATE

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

cutting

CUTTING

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.

bevel

BEVELING

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

bending

BENDING

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.

welding

WELDING

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

CIRCUMFERENTIAL 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

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 

FINISHED PIPE

The finished pipe is then removed and ready for delivery.
