The seamed pipe is welded out after the steel plate is formed; The seamless pipe is rolled out with a steel bar through a piercing technique; Generally speaking, the price of seamless pipes is higher than that of seamed pipes, and the pressure-bearing capacity of the same wall thickness is also high with seamed pipes. However, modern welding technology can also achieve the quality of seamless pipe, and the advantage of seam pipe is that the wall thickness is even. This pipe knowledge is provided by.
