Which is cheaper, welded steel pipes or seamless steel pipes, for small diameters? ? Where is the dividing line? It seems that welding small-diameter steel pipes is actually more difficult

Welded pipes are made from steel plates; it is more difficult to roll smaller-diameter pipes than larger ones

The price of small diameter tubes is related to the thickness; thickness
