<p>A fiber-reinforced plastic pipe and a centrifugal casting method for the preparation therof, in which the pipe wall contains filler and reinforcing fibers; in the preparation, at both pipe ends on the outer side of the pipe wall, a lug having a length of between 40 and 150 mm and, optionally, at one or several points throughout the pipe on the outer side thereof, slots having a width of between 80 and 300 mm are respectively formed in situ. This is performed using a centrifugal casting mold disposed in which, on the inner side at both ends thereof, are insert rings corresponding to the size of the lugs and, provided at one or several points, longitudinally of the mold, are insert rings that correspond to the size of the slots.</p> |
