    摘要: A method and apparatus for stabilizing an interior surface pipe within an exterior casing pipe are disclosed. The casing stabilizer apparatus comprises a cylindrical separable hanger body made up of a pair of body half-sections. Each body half-section includes tapered exterior walls and an interior bore with serrated teeth therein for gripping a surface pipe placed within said bore when assembled. A downward depending lip portion defining a space for engaging the uppermost end of the exterior casing pipe is also provided on each hanger body half-section. A locking means is provided for securing the body half-sections together. The hanger body is attached to an interior surface pipe above the exterior casing pipe, and then lowered onto the exterior casing pipe.
