ABSTRACT:
One embodiment of the present invention is an insulated curved metal pipe characterized by a curved body of a given length having a first section, a central section and an end section. The body has a monolithic refractory lining extending for the length of the body which is in contact with the internal surface of the first section and second section and which is spaced apart from the internal surface of the central section by a flexible insulating material, whereby the insulated curved pipe has greater flexibility (i.e., less stiffness) than otherwise possible when the cast refractory is in contact with the internal surface of the entire curved body. The curved pipe also includes a plurality of anchors attached to the internal surface of the curved body. Importantly, the anchors in the central section are sufficiently flexible to permit at least some deformation of the central section of the body relative to the refractory.
