ABSTRACT:
A mold made of steel and intended for manufacturing tubular objects by a centrifugal casting concrete method is formed of two semicylindrical shells having longitudinal flanges to which locking wedges are welded. The locking wedges provided on the two opposing flanges have oblique surfaces cooperating with each other. The oblique surfaces of the locking wedges extend over a plane of separation between two flanges when the mold is in a closed position.
