Difference between seamless and welded pipeSeamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or seam.It is suitable for bending and flanging. The most advantage is increasing the ability of withstanding higher pressure.Seam

Steel pipe piles are widely used in various situations such as supporting piles and friction piles. Especially when it is used as a supporting pile, it can be fully driven into a relatively hard supporting layer, so it can exert the bearing effect of the strength of the entire section of the steel.

1) The size of steel wire, steel bar, steel pipe in diameter, steel wire rope, etc., can be expected in a well-ventilated storage shed, but it needs to be the bottom of thatch.2) Steel products, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various

The difference between hot-rolled seamless steel pipe and cold-rolled seamless steel pipeIn terms of processing technology: Hot rolling is hot processing, and cold drawing is cold processing. Hot rolling is rolling above the recrystallization temperature, and cold rolling is rolling below the recrys
