Seamless steel pipe and welded pipe are mainly different molding process. Welded steel pipe, such as water pipes, generally through the flat plate by welding after bending up, you can find a seam in the above; is generally thicker in diameter spiral weld. The seamless steel pipe is generally the molten steel through the annular slit of the backlog by stretching out before treatment processes such as molding, so that no seam. In performance, especially on the bearing capacity has greatly improved as compared with ordinary steel, it is often used for high voltage devices. Such as hydraulic equipment, piping connections. The welded steel pipe weld area is its weak link, weld quality is also affecting the overall performance of the main factors
Seamless pipe: seamless steel pipe is a kind of hollow cross-section, no seams around the circle, square, rectangular steel. Seamless steel pipe or solid steel ingot is made of the capillary tube through the hole, then through the hot-rolled, cold rolled or cold call is made. Seamless steel pipe with a hollow cross-section, a large number of pipes for conveying fluids, such as steel and solid steel round bar compared to the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding.
Welded pipe: welded steel pipe, also known as pipe, plate or strip is formed through the curl made of steel after welding. Welded steel pipe production process is simple, efficient, and more varieties and specifications, equipment, less capital, but the general strength of less than seamless steel pipe.
