Advantages and Disadvantages of Welded Steel Pipe

Welded steel pipe is a continuous online production, the thicker the wall, the greater the unit and the investment in welding equipment, it is more economical and practical. The thinner the wall thickness, its input-output ratio will be a corresponding decline. The process of the product to determine its advantages and disadvantages, the general welding steel pipe with high precision, uniform wall thickness, tube inside and outside the table high brightness (steel plate surface grade steel pipe surface brightness), can be any length. Therefore, it is in the high-precision, low-pressure fluid applications reflects its economy and aesthetics.

Welding steel pipe production process is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the pipe with larger diameter can be produced with the narrow billet. The pipe with different diameter can also be produced with the same width. However, compared with the same length of the straight pipe, the weld length increased by 30 to 100%, and the production rate is low. Therefore, the smaller diameter of the pipe are mostly used straight seam welding, large diameter welded pipe are mostly used spiral welding.
