摘要： A tube coupling assembly includes first and second generally cylindrical coupling components each terminating in a radially outwardly extending flange surrounding a sealing end face. The coupling components are positioned in axial alignment and an improved nut assembly is provided for selectively driving the sealing end faces toward one another. The nut assembly comprises a sleeve-like main body positioned in surrounding relationship to the first and second coupling components. A nut member is threadedly connected with a first end of the main body and engages with the radially outwardly extending flange on the first coupling component on the side opposite its sealing face. A split-ring connector comprising cooperating half-ring members is positioned in surrounding relationship to the second end of the main body and releasably connected thereto. The half-ring members include radially inwardly extending flanges engaged with the radially outwardly extending flange on the second coupling component on the side opposite its sealing face.

摘要： A gasket and retainer arrangement for use in a coupling of the type having first and second coupling components with opposed end faces including sealing ribs extending axially therefrom with an annular sealing gasket interposed therebetween comprises a retainer device for maintaining the gasket in a predetermined located position relative to the end face of one of the components. The retainer includes a generally sleeve-like body defining a retaining portion closely received over the one component at an area rearwardly from the associated radial end face. A plurality of axially extending leg portions are spaced about the retaining portion and extend axially beyond the associated end face. The annular sealing gasket has an outer periphery of a diameter at least slightly greater than the inner diameter of the sleeve-like body with recesses formed in the outer periphery to receive the axially extending leg portions whereby the gasket is maintained in aligned relationship with the end face.

摘要： An orbital welding apparatus comprising a modular weld head unit including a circular rotor carrying a welding electrode for rotation about an axis for welding abutting ends of tubular members positioned in alignment on the axis. A drive assembly for driving the rotor includes a motor unit carried in a separate modular housing for ready manual connection and disconnection from the weld head unit. In the preferred form a transmission module is connected with the motor unit and connects to the weld head unit by a flexible drive shaft assembly to allow the motor unit to have substantially any desired orientation relative to the weld head unit. There is also disclosed a separate clamping assembly for holding the tubular members relative to the weld head unit.

摘要： A tube coupling comprises first and second coupling components having transversely extending sealing end faces in aligned face-to-face relationship. First and second nut members are arranged to drive the sealing end faces toward each other. An annular anti-twist member is located between the first nut means and the first coupling member for conducting axial forces from the first nut member to the first coupling component. The annular anti-twist member and the second nut member include axially engaged portions for preventing relative rotation therebetween.

摘要： A clamping device for holding cylindrical workpieces having a nominal radius R which varies from a minimum of (R-A) to a maximum of (R+B), where A and B are the limits of the tolerance range for the nominal radius. The clamping device includes opposed clamp halves each having a clamp face adapted to be moved toward and away from one another and each of the clamp halves carrying a rigid collet element adapted to engage on opposite sides of cylindrical workpieces when the clamp halves are moved toward one another. According to the disclosure, each of the collet elements has a semi-cylindrical clamping surface extending inwardly from the clamp face of the respective clamp half. Each semi-cylindrical clamping surface has a radius substantially equal to R+B) with the center of the radius being offset outwardly of the clamp face of the respective clamp half an amount at least equal to (A+B). Preferably, the center of the radius is offset an amount at least equal to (A+B+C), where C is the tolerance deviation permitted to the radius (R+B).
