Spiralweld Pipe Manufacturing

The spiralweld manufacturing process is one of the most cost effective ways to produce steel pipe. The mill setup offers a varying degree of flexibility, allowing for a wide range of pipe diameters and wall thicknesses to be produced. As a result, Skyline Steel is able to offer spiralweld products to many structural and non-structural markets at the most economical cost.

Weld Method
The weld is the critical structural component of the spiralweld process. All Skyline Steel spiralweld pipe is manufactured using the Double-Sided Submerged Arc Welding (DSAW), also known as Electric Fusion Welded (EFW) technology. During the DSAW process, the molten weld and the arc zone are protected from atmospheric contamination by being submerged under a blanket of granular fusible flux. When molten, the flux becomes conductive and provides a current path between the electrode and the base metal. The penetration achieved by using the DSAW process allows for higher weld travel speeds, without sacrificing quality; ultimately resulting in improved productivity and lower costs.

Spiralweld Process
Skyline Steel's production facilities capitalize on ultra-modern pipe rolling technology. Steel is continuously fed into the mill, edges are prepared and the pipe is welded on the inside diameter (ID) and outside diameter (OD) thus generating full penetration welds.
