Advantage of welded steel pipe

Welded steel pipe is continuous online production, the thicker the thickness, the unit and dissolves equipment investment, the less it has economical and practical. The thinner wall thickness, its input-output ratio will be reduced. The advantages and disadvantages of the process of the product decided it, general welding steel tube of high precision, uniform wall thickness, high brightness tube appearance (level determines the surface of the steel plate of steel tube surface brightness), can be arbitrary length. As a result, its application in high precision, low pressure fluid embodies its economy and aesthetics.

Welded steel pipe production technology is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than straight seam welded pipe, use a narrow billet production of larger diameter welded pipe, you can also use the same width of billet in the production of different pipe diameter welded pipe. But compared with the same length of straight seam pipe, weld length by 30 ~ 100%, and the production speed is low. As a result, a small diameter welded pipe are mostly with straight seam welding, large diameter welded pipe for the most part adopts spiral welded.
