Abstract
A non-curable injectable ester containing packing material for use in the repair of leaking valves contains a calcium sulfonate grease containing at least one polyalphaolefin, an ester, an anti-wear/anti-galling agent, a binding/thickening agent and a plasticizing agent.
Claims20
An injectable packing stick extrusion for use in the repair of a leaking valve subjected to fluid flow through or into a conduit controlled by the valve, the packing stick extrusion comprising:
- (a) a calcium sultanate complex grease comprising at least one polyalphaolefin;
- (b) at least one anti-wear/anti-galling agent;
- (c) at least one binding/thickening agent;
- and
- (d) a plasticizing agent miscible with the calcium sultanate complex grease
- wherein the packing stick extrusion, when injected, repairs the valve without interrupting the flow of the fluids through or into the conduit.
An extruded stick for repairing valve gates or stems comprising:
- (a) a calcium sultanate complex grease comprising at least one polyalphaolefin;
- (b) at least one anti-wear/anti-galling agent;
- (c) at least one binding/thickening agent;
- and
- (d) a plasticizing agent miscible with the calcium sulfonate complex grease wherein the extruded stick is capable of adhering to the valve gate or stem to be repaired and further is resistant to degradation and decay caused by the action of water and hydrocarbon within a conduit controlled by the valve gate or stem and further wherein the extruded stick exhibits a cone penetration value at 77° F. from about 75 to about 100, ASTM 0217.
A water-insoluble valve packing extruded stick for use in the repair of a leaking valve subjected to fluid flow through or into a conduit controlled by the valve, the extruded stick comprising:
- (a) a calcium over-based sulfonate in a base oil, the base oil comprising a lubricating oil and a polyalphaolefin oil;
- (b) at least one anti-wear/anti-galling agent;
- (c) at least one binding/thickening agent;
- (d) an ester;
- and
- (e) a plasticizing agent miscible with the calcium sulfonate complex grease wherein the non-curable water-insoluble valve packing stick has a putty consistency and, when injected, repairs the valve without interrupting the flow of the fluids through or into the conduit and further wherein the non-curable water-insoluble valve packing stick exhibits a cone penetration value at 77° F. from about 75 to about 100, ASTM D217.
