How To Classify The Welded Pipe According To The Cross-section Shape

- Jun 30, 2017 -

Welded pipe According to cross-section shape can be divided into round pipe and abnormity pipe. The special-shaped tube refers to a variety of non-circular cross-section of steel pipe, including the wall thickness and unequal wall thickness. The special-shaped pipe with the same wall thickness is a non-circular circular cross-section with the same shape in the inner and outer contour of the Annular cross section; The most of the special-shaped tubes with thick wall are produced by cold drawing and special shaped pipe production line. The special-shaped pipe with unequal wall thickness is produced by extrusion or cold drawing. Special-shaped tube mainly include: square tube, rectangular tube, oval tube, flat oval tube, semicircular tube, hexagonal tube and equilateral tube, and so on, as shown in the diagram below as a variety of profiled steel pipe cross-section shape.
