Are metal spiral tubes the same as metal bellows?
The spiral tube called spiral steel tube or spiral welded pipe, the low carbon steel or low alloy structural steel strips in a helical line certain angle (called forming angle) rolled into a tube, then the tube welding seam made up, it can be used in narrow strip production of large diameter steel pipe. The pitch of a spiral pipe is much larger than that of a bellows.
Hello. The two are not the same. The difference lies in. The pitch of a spiral pipe is much larger than that of a bellows. The maximum material thickness of the spiral tube is much thicker than that of the bellow. The diameter of a spiral tube can be very large. But the bellows can't be too big in diameter.
The spiral pipe is mainly used in the pipeline of petroleum and natural gas, and its specifications are indicated by outer diameter * wall thickness.
The corrugated pipe is extruded by the extruder, the winding pipe is wound in a circle, and the prestressed metal corrugated pipe is a reserved channel.
