ABSTRACT:
A method and apparatus for rolling transversely ribbed pipe consists in that the rib after forming is deflected in the direction of rolling parabolically, the external pipe is pressed down to the core pipe, and deflecting the rib and pressing down the external pipe onto the core pipe is carried out during one revolution of the pipe, and afterwards the rib is straightened.
The apparatus has three tools provided with roll-formed disks, for supporting and straightening, whereby the second - in the direction of rolling - part of the profile of supporting disks is concave, preferably parabolically, and the last - in the direction of rolling - tool is provided with a supporting disk the outer diameter of which is from 0.1 to 0.8 mm larger than the outer diameter of the other supporting disks.
