Abstract: A method and apparatus for an improved safety cam lock fitting having side by side double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on the inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space therein between. A lever latching mechanism may be used to prevent the cam levers from being inadvertently opened.

Abstract: A fluorine gas functionalized surface of a fixture is chemically bonded to a fiberglass sump using a resin. The resin chemically reacts with the functionalized surface creating a strong, chemical bond between the fixture, which penetrates the shell of the sump, and the fiberglass shell of the sump. For example, the surface of the fixture is functionalized by a fluorine-containing gas mixture in an autoclave at a temperature, pressure and duration that creates C?O double bonds at the surface of a polyethylene fixture. The resin chemically reacts with the C?O double bonds and bonds with a fiberglass transition fitting capable of being joined to the shell of the sump.

Abstract: A process for treating a pin having an external threaded portion and a box having an internal threaded portion wherein the process provides a threadable joint having a high galling resistance. One embodiment of the present invention includes applying a lubricant on the threaded portion of at least one of the pin and box. The threadable joint is made up by threadably engaging the threaded portions of the pin and box to a recommended torque according to the American Petroleum Institute and then breaking out the threaded joint. The making up and breaking out step with lubricant applied on the threaded portion of at least one of the pin and box is performed a plurality of times. One of the threaded portions of the pin and box is then case hardened. The threadable joint made from this process is highly resistant to galling without the requirement of any lubricant.
