API Female/Male Threaded Welded Fig 2002 Fig 2202 Hammer Union

Hammer Unions are designed to enjoin mud tanks instantly without having to deal with the flange connections at all. If the mud tanks are not aligned in the right kind of way necessary hammer unions can still be used in order to make absolutely non-leak seals that are tightened. They generally have three parts, a male, a female, and a nut. The male part is an external threaded portion that is welded on the end of a pipe already connected to a tank wall. The pipe continues further through the nuts towards the O-ring in order to enter into the female part. They are then hammered and tightened together. Hammer adjustments are the most necessary parts. Unions have a locked up O-ring that is squeezed together into the "D" square cross section area thereby sealing the fluid pressures up to 150 psi in opposition to the external diameter of the connecting pipe in the hammer unions.
