Large-Diameter Welded Steel Pipe
large-diameter welded pipe is manufactured at the
Kashima Steel Works. The steel plates are first
bent into U-shapes, formed into round shapes by
the O-ing press, and then have their seams submerged-arc
welded. With over 90 percent of these large pipes
used in energy fields such as oil and natural gas
pipelines, reliability is the foremost demanded.
Sumitomo Metals is already the global leader in
the manufacture of high-purity steel pipe resistant
to corrosion from hydrogen sulfide, high-strength
heavy wall pipe to withstand high-pressure transport,
and other high value-added products.
