Welded Stainless Steel Pipes
Stainless steel welded pipe in the production process, the tank will be uniformly squeezed, and then the line bright solid melting annealing, then the surface will become very smooth, so that it is not easy to scale, but also easy to clean, to achieve the purpose of saving time and effort. In addition, its wall thickness is uniform and can be arbitrarily measured, so its accuracy is very high. Moreover, stainless steel also has good corrosion resistance, so its service life can be very long.
