Abstract: The invention is a round, flexible, hollow tubular insert to be affixed in a central position within pressurized sprinkler pipes, water pipes and water mains. The insert will be employed to prevent sprinkler pipe, water pipe and water main ruptures due to the water within the sprinkler pipe, water pipe or water main freezing.

The insert is constructed with guides to maintain a position in the center of sprinkler pipes, water pipes and water mains to absorb the radial freezing of water. By such absorption, the outer sprinkler pipe, water pipe or water main itself will not be over-pressurized, thereby avoiding the possibility of a rupture. Upon the thawing of the frozen water, the flexible, hollow, tubular insert will return to its original shape.

Abstract: A rotating tag bar is positioned below a progressive cavity pump stator for supporting at least a portion of a rod string a rotor. A tubular housing is secured to the stator and is fitted with a rotatable platform. The platform blocks downward stretch of the rotor and then rotatably support the rotor on a thrust bearing. Thereby, rotor-imposed loads on the platform translate into tensile loads directed into the stator, which is suspended from tubing string, lessening the load on the rod string and thereby both reducing the need for extreme accuracy in rotor positioning and reducing rod string and tubing wear. Optionally, a no-turn tool transmits load from the stator into the casing. In operation, the rotor is landed to contact the platform. The rotor is then lifted a distance less than the anticipated stretch so that when in operation, the rotor sets down on the platform and transfers at least a portion of the rod string load into stator.
