A hammer union includes a male sub, a threaded female sub, a threaded union nut disposed around abutting ends of the threaded female sub and the male sub, the abutting ends of the threaded female sub and the male sub include contact surfaces perpendicular to a longitudinal axis of the hammer union, and an outermost diameter of the perpendicular contact surfaces and a minor thread diameter of the female sub are equidistant from a longitudinal axis of the hammer union. A method of assembling a hammer union includes inserting a plurality of load segments between a threaded union nut and a male sub, threadedly engaging internal threads of the threaded union nut with external threads of a female sub, and engaging flat contact surfaces of abutting ends of the male sub and the female sub.

A discharge arm assembly for a truck or trailer-mounted pumping unit comprises a jumper line which is connected to the outlet of the pumping unit, a base unit which is connected to the outlet of the jumper line, and an articulated arm which is connected to the outlet of the base unit. The base unit includes a base conduit which is rigidly secured to the truck or trailer and a swivel arm which is rotatable about a generally vertical axis. The articulated arm comprises a first generally straight pipe which is connected to the swivel arm by a generally 90&#xb0; elbow. A brace member comprises a first end which is connected to the swivel arm and a second end which is connected to the first pipe to thereby support the first pipe for movement in a generally horizontal plane.
