Abstract
PURPOSE: To prevent the generation of microcracks, increase the speed of pipe making and improve productivity by warm forming a titanium or its alloy strip at specific temps. en route of processes for forming the same into a pipe shape.
CONSTITUTION: A strip 1 consisting of titanium or its alloy is passed between fin pass rolls 2a, 2b, and is formed into a pipe shape. Between fin pass rolls 2b, 2c prior to welding with squeeze rolls 5, the strip 1 is heated to below 400°C and above the temp. defined by the equation I, where T is the lower limit temp. °C, t is pipe wall thickness mm, R is pipe radius mm down to the central part of the wall thickness, and v is pipe making speed in m/min. Thence, it is warm formed with fin pass rolls 2C, and is passed through the rolls 5 and sizing rolls 2d, whereby it is made into a pipe. Here, the reason for limiting the upper limit of the heating temp. lies in that above the limit temp. coloring occurs in the surface of the stirp.
