The difference between Q345B reelpipe, Q345B LSAW pipe and Q345B SSAW pipe

Q345B reelpipe is formed steel pipe billet from the steel plate through the roller machine, and then welded into Q345B steel pipe by submerged arc welding or electric welding, and then to other plastic equipment to fix the diameter. The single production efficiency of Q345B reelpipe is low, and pipe quality is unstable, dimensional precision is low, but simple equipment investment for Q345B reelpipe is not that high.

Q345B LSAW pipe is formed by the high frequency welded pipe machine, then the Q345B steel pipe is welded by high frequency heating. The outer burr is scraped off through the scraper. Finally, the straight seam Q345B LSAW welded pipe is produced by cutting the diameter and cutting the size. This is the production method of straight Q345B LSAW welded pipe which is usually described now. It is literally a straight welded pipe. The straight welded Q345B LSAW pipe has the advantages of high efficiency, high pipe quality, high precision and good unity. It is the first choice for large-scale steel pipe production.

The difference between the Q345B LSAW pipe and Q345B SSAW spiral welded pipe is that the weld line of Q345B SSAW pipe is a spiral curve, but both Q345B LSAW pipe and Q345B SSAW pipe as well as Q345B reelpipe are welded steel pipe.
