SPIRAL WELD PIPE. Spiral Weld Pipe, as the name implies, is a steel pipe which has a seam running its entire length in a spiral form.

Continuous Weld pipe in sizes NPS 1V2 and smaller are normally put in standard bundles as indicated in the following chart.
Spiral pipe (helically welded pipe) has been produced industrially in the U.S. since 1888. Production technology for longitudinally welded and helically welded pipe developed more or less in tandem, but somewhat staggered in time, which resulted in some pipe being applied in operations for which they were not produced.he real issue is not whether a pipe is helically welded or longitudinally welded; the issue is who made the pipe and what technology was used with what experience â regardless whether it is longitudinally or helically welded pipe.
