ABSTRACT:
An anchor support is provided for a double-containment piping assembly having at least one outer piping component defining a first diameter, and at least one inner piping component received within the at least one outer piping component and defining a second diameter less than the first diameter and forming an approximately annular space between the inner and outer piping components. The anchor support has a cylindrical outer-component support section defining a first approximately annular support surface having a first diameter approximately equal to the first diameter of the at least one outer piping component for contacting and supporting the outer piping component. An approximately cylindrical inner-component support section of the anchor support is spaced laterally relative to, and located approximately at an opposite end of the anchor support relative to the outer-component support section. The inner-component support section defines a second approximately annular support surface having a second diameter which is less than the first diameter and approximately equal to the second diameter of the inner piping component for anchoring and supporting the inner piping component within the outer piping component. A tapered connecting section of the anchor support defines a conical-tapered surface extending between the outer-component support section and the inner-component support section and tapering inwardly from one end adjacent to the outer-component support section to another end adjacent to the inner-component support section.
