Advantages of large diameter stainless steel pipes

1. Welded steel pipes are produced continuously online. The thicker the wall thickness, the greater the investment in the unit and welding equipment, and the less economical and practical it is. The thinner the wall thickness, the corresponding decrease in its input-output ratio.

2. The process of large-diameter stainless steel pipes is determined. Generally, welded steel pipes have high precision, uniform wall thickness, and high brightness inside and outside the pipe (the surface brightness of the steel pipe is determined by the surface grade of the steel plate), and can be arbitrarily scaled. Therefore, it embodies its economy and aesthetics in high-precision, medium- and low-pressure fluid applications.

3. The production process of welded steel pipe is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the welded pipe with a larger diameter can be produced with a narrower billet, and welded pipes with different diameters can be produced with the same width billet. However, compared with the straight seam pipe of the same length, the weld length is increased by 30~100%, and the production speed is lower. Therefore, most of the welded pipes with smaller diameters adopt straight seam welding, and most of the large-diameter welded pipes adopt spiral welding.
