-14- TWIST LOCK JUNCTION BETWEEN REFRACTORY TUBULAR SHAPES ABSTRACT OF THE DISCLOSURE The disadvantages of the prior art are substantially overcome by a twist lock junction and method having the mating joints of refractory tubular shapes formed in a polygonal configuration. Each junction includes a polygonal female recess and a complimentary interfitting polygonal male projection. The female recess is dimensionally larger than that of the adjoining male projection. When either the female or male joint is rotated clockwise or counterclockwise relative to the other, a multi point wedging or "twist lock" effect occurs. This wedging condition offers a tighter fit than the conventional gravity or circular fit. In addition, this "twist lock" effect squeezes the mortar applied to the joints and forces a thin seal near the sites of the point loading. This decreases the chance of metal leakage or fracture of the mortar seal due to mechanical abuse.
