Abstract: A fluid connection joint to couple tubular pipes intended to convey gas, compressed air and other fluids. The fluid connection joint includes a deformable internal ring having sealing surfaces internally to engage with an outer surface of a first tubular element and frontally to engage with a second tubular element. The deformable internal ring is located within a housing that is coupled to a flange of the second tubular element by fixing screws. The tightening of the fixing screws results in a substantially radial compression of the internal ring and seals around the first tubular element and a second substantially axial compression of the frontal seal against the flange.

Abstract: A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may be a non-integral torque collar. Alternatively, the fitting may also be pulled up by turns or may have an integral torque collar. In still another embodiment, a stroke limiting member is provided that may be used to enable a fitting that is designed to be pulled up by turns to also be pulled up by torque. In other embodiments, the non-integral torque collar may be installed onto one of the fitting components, and then deformed so as to prevent or make it more difficult to remove the torque collar after installation onto the fitting component.

Abstract: This invention relates to a surface heat treatment method in a salt bath at low temperature, suitable for partially hardening the surface of a workpiece through heat treatment, including plating the surface of a workpiece with a first metal layer; partially peeling the first metal layer; heat treating the workpiece at a temperature of 400 to 500° C. for a predetermined period of time; and totally peeling the first metal layer. Thereby, low-temperature heat treatment is effective at heat treating the workpiece while minimizing deterioration of corrosion resistance.

Abstract: An improved compression conduit fitting to be attachable to threadless conduit. The conduit fitting includes a generally cylindrical body with a longitudinal internal bore extending therethrough. The body has an externally threaded conduit receiving end and an externally threaded conductor egressing end located opposite the receiving end. A gasket of annular shape is placed within the internal bore of the body. Moreover, an internally threaded gland nut of annular shape is slideably positioned over the conduit to be securely attached to the body. Finally, a compression ring of annular shape is interposed between the gland nut and the body to compresses one end of the conduit against the gasket, thereby forming a liquid tight seal.
