	Q235b advantages of spiral steel pipe
      

      
	Spiral welded pipe strength is generally higher than the straight seam welded pipe can be used to produce a larger blank diameter pipe larger pipe can also use the same width of the diameter of the pipe production of different pipe. However, compared with the same length of the straight seam pipe, weld length increased by 30 to 100%, and the production rate is low. Therefore, most of the smaller diameter welded pipe straight seam welding, large diameter spiral welded pipe are mostly used.
