Rolling Mill Stands are used to control the outer diameter of the pipe during the elongation and diameter finishing processes. Mill Stands in rolling mills consist of several components and systems, all of which are subject to high temperatures, high loads and extreme conditions. API Engineering has been involved in the design and supply of a variety of custom built rolling mill stands for Seamless Tube Mills around the world.
Roll stands are designated by the roll shaft diameter. For example, our RT-1000 stand is a 1 shaft machine, and our RT-8000 stand is an 8 shaft machine. Our single-point adjustment (SPA) top roll shaft adjustment has essentially become a standard feature on all new mills. It also can easily be retrofitted to your existing mill whether its a Rafter machine or not.
