  • Patent number: 8042252
    Abstract: The coupling includes a mandrel and a coupling outer sleeve. In a method for installing the coupling on a pipe, the mandrel is inserted into the inner diameter of an end of pipe with an outboard end of the mandrel protruding from an end of the pipe. Then the outer sleeve is positioned over the pipe to form a length of substantially concentrically arranged, overlapping parts of the mandrel, the pipe and the sleeve. Then the sleeve is crimped over at least a portion of length, which engages the pipe between the sleeve and the mandrel. Either before or after sleeve is crimped over the pipe, the sleeve is connected to the outboard end of the mandrel.

  • Patent number: 8017562
    Abstract: Phosphate esters useful for gelling hydrocarbons in combination with a metal source are disclosed along with methods of preparation of the phosphate esters. Fouling in oil refinery towers has been attributed due to distillation of impurities present in phosphate esters used to gel hydrocarbons for oil well fracturing. The improved method of preparation of the phosphate ester results in a product that substantially reduces or eliminates volatile phosphorus, which is phosphorus impurities that distill up to 250° C., and increases the high temperature viscosity of the hydrocarbon gels formed using the phosphate esters.
