Abstract: A tubular member 12 having an internal and/or external metal thread 18, 20 at one end thereof, at least part of the thread 18, 20 being coated with an alloy of copper and tin, said alloy containing 5 wt % to 95 wt % copper. The tubular member 10 can be combined with another tubular member 14, 16 to provide a threaded connection 10 having improved galling resistance.
Abstract: A pipe connector comprises a tubular pin member having an outer generally frusto-conical peripheral surface provided with annular projections, and a tubular box member having an inner peripheral surface corresponding to the peripheral surface of the pin member, which overlies the peripheral surface of the pin member when the members are fully engaged together, and is provided with annular grooves in which the projections on the pin member are engaged. At the inner end of the peripheral surface of the pin member, the pin member is provided with an annular projection extending in the direction of the free end thereof, overlying the peripheral surface thereof and providing a first radially outer radial surface portion and a second radially inner radially inwardly directed surface portion. The free end of the box member is provided with corresponding radial and radially outwardly directed surface portions.
