Show that you are care to your family, and that's what I've done last night. I have to taken care a few problems in my family, start from my daughter and the others, and I feel so free now because the problems step by step will solved, I hope. And now continue with the Pipe and Fabrication, now we will know more about Rolled Pipe, Root Edge, Root Face, etc.
Rolled Pipe.
![]() |
rolled pipe |
Pipe produced from a forged billet which is pierced by a conical mandrel between two diametrically opposed rolls. The pierced shell is subsequently rolled and expanded over mandrels of increasingly large diameter. Where closer dimensional tolerances are desired, the rolled pipe is cold- or hot-drawn through dies and then machined. One variation of this process produces the hollow shell by extrusion of the forged billet over amandrel in a vertical, hydraulic piercing press.
Root Edge.
A root face of zero width.
Root Face.

nomenclature root face |
