Abstract
PURPOSE: To make it possible to manufacture a titled pipe in which the innermost layer is formed by a coil of a thin plate thickness by winding the innermost layer and the 2nd layer on a mandrel of the same size as the inside diameter of a required pipe until at least the winding of the 2nd layer to a round is finished.
CONSTITUTION: A strip plate 1 being a coil material of an extra thin plate thickness for forming the innermost layer is too low in rigidity to permit sound welding when it alone is wound spirally. This also gives trouble such as infeasibility of winding a strip plate, thicker than the plate 1, to be wound later at a minimum interlayer space. To prevent this, the strip plate is wound on the mandrel 3 which is made coincide its outside circumference with the inside circumference of the required pipe and it is bound by welding. Accordingly, the mandrel 3 is only required to have a length in the pipe axis direction up to where the winding of the strip plate 2 of the 2nd layer to a round is finished. The mandrel, with its center of revolution being the center of the pipe axis, is rotationally driven at a peripheral speed corresponding to the feed speed for winding. In the case of winding to 3 or more plies, there is no need for the mandrel 3.
