Difference between straight seam steel pipe and seamless steel pipe

- Dec 28, 2016 -

Straight seam steel pipe and seamless pipe production technology are the main differences, there are two parts. Straight seam pipe is the iron after bending, the comfort, welding processes, such as production, allowing a weld. Seamless hot-rolled round steel through the mill is out, there is no welds.

Curly straight seam steel pipe is made of steel by welding to complete, is no weld cracks for seamless, seamless pipe is made of round steel produced an overall circular steel tubes directly, using embryos directly out of steel. Straight seam steel or pipe is after curly made of welded steel pipe after molding, welded steel pipe production process is simple, high production efficiency, different specifications, General strength of less than seamless. Straight seam steel pipe and seamless pipe production technology are the main differences, there are two parts. Straight seam pipe is iron, press

Bend, hekou, welding processes, such as production, allowing a weld. Seamless hot-rolled round steel through the mill is out, there is no welds. Seamless and ERW pipe diameter wall thickness equal circumstances, pressure on the seamless pipe and solid, is much greater than for straight seam pipe. High pressure tube for engineering chose seamless, no pressure or low pressure works in permitting, to choose cheap straight-seam pipes.
