Extrusion method for seamless steel pipe

With the wide application for seamless steel pipe, manufacturers would adopt more advanced technology for the high quality products for customers. And today, we would like to discuss a kind of basic production process for seamless steel pipe-extrusion method.

First of all, what’s the definition of extrusion method. It means the metal blank into the extruder barrel, under this situation, extrusion molding and extrusion rod will compose of "closed" container by applying pressure to force the metal extruded rod extrusion die orifice outflow from. And then, for the direction of extrusion and metal lever, we will divide extrusion method into two kinds. They are forward extrusion and backward extrusion.
