Les tuyaux carrés en acier carbone creux sont des sections structurelles creuses en acier au carbone. Ils ont une coupe carrée et sont utilisés dans une variété d'applications, y compris la construction, l'ingénierie et la fabrication. Ces tuyaux sont connus pour leur force, leur durabilité et leur résistance à la corrosion. Ils sont généralement fabriqués à partir d'acier au carbone à chaud ou formé à froid et peuvent être produits dans une gamme de tailles et d'épaisseurs. Les extrémités des tuyaux peuvent être carrées, biseautées ou simples, selon l'utilisation prévue. Les tuyaux carrés en acier en carbone creux sont couramment utilisés dans la construction de bâtiments, de ponts et d'autres structures, ainsi que dans la fabrication de machines et d'équipements.

| Short Description | Spiral welded pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe. Full scale tests have shown that high quality spiral welded pipe is as strong as API pipe. The strength and flexible manufacturing of spiral welded pipe make it the product of choice for a variety of applications. |
