The merchandise covered by this order is welded carbon and alloy steel structural pipe (other than stainless steel pipe), more than 406.4 mm (16 inches) in nominal outside diameter (large diameter welded structural pipe), regardless of wall thickness, length, Production processes for Welded Pipes IspatGuruSteel pipes are long, hollow tubes which are used mainly to convey fluid or fluidized products from one location to another. They are produced mainly by two distinct production processes which result in either a welded pipe or a seamless pipe. Welded steel pipes are produced with either a longitudinal seam or a spiral (helical) seam.
Early carbon steel pipe producers employed a manufacturing method called butt-welding. The butt-welding process was quite elementary in that it merely rolled a piece of heated steel plate into tubular form and created a longitudinal weld through compression and direct heat.Electric Resistance Welded Pipe, ERW Steel Pipes, Electric direct coiling welded steel pipeASTM A178 standard referes to electric-resistance-welded tubes with minimum-wall-thickness.

No filler is used in making the weld.
Structural welding is a process by which the parts that are to be connected are heated and fused, with supplementary molten metal at the joint. A relatively small depth of material will become molten, and upon cooling, the structural steel and weld metal will act as one continuous part where they are joined. Fillet weld Fillet weld 1Carbon Steel Pipe - an overview | ScienceDirect TopicsSteel pipes are fabricated from steel plate bent to a circular form or they may be continuously produced from a coil of steel strip bent to a spiral and butt welded along the spiral seam. Joints between coil ends of spiral welded pipes are known as skelp end welds.Effects of Corrosion on Mechanical Properties of Welded direct coiling welded steel pipeIn this study, welded carbon steel pipe (SPW 400) was used to evaluate the change of its mechanical properties according to corrosion accelerations performed at various quantities of electric char direct coiling welded steel pipe
In this paper, a new steel damper named X-shaped pipe damper (XPD), is proposed and examined. The proposed damper is made through welding two oppositely positioned pipe halves to form a X-shaped core, and connecting the X-shaped core to side plates with fillet welds or circumferential welds.History, Uses, and Physical Characteristics of Steel Pipestrength. As welded pipe became predominant, using 50 percent of the material yield stress became widely accepted. Helically formed and welded pipe was developed in the early 1930s and was used extensively in diameters from 4 in. (100 mm) through 36 in. (875 mm).
