What are Hammer Unions?

The Benefits of Using the Standard Union

Hammer unions in particular are designed to enjoin mud tanks instantly without having to deal with the flanged connections at all. In case if the issue is so that the mud tanks are not aligned in the right kind of a way necessary hammer unions can still be used to in order to make absolutely non-leak seals that are tightened.

Parts of the Product for Union Drilling

Hammer Unions in general have three parts, a male part, a female part and a nut part. The male parts of the unions are the external threaded portions that are welded to the end of a pipe that is connected to the tank wall. Hammer union nut is through which the pipe continues further leading to the huge o-ring thereby entering into the female part. Hammer adjustments are the most necessary parts. The nut that is threaded on the interior is hammered and tightened on to the female part. 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. Unions generally are available in the market in two basic types,

  • Hammer Standard Union
  • Hammer Sour Gas Union

But you should remember not to accidentally swap the standard service parts with the sour-gas service parts.

Important Characteristics of Manufactured Products

Unions that characterize quality are inspected thoroughly by the manufacturer to ensure that they give service over a prolonged period of time and show tenacity even under extreme conditions. Unions generally have three haul nuts and self-locking ACME threads which offer quick make-up and break-out at the same time. Unions are often color hinted in order to ensure swift and easy identification. Unions may also include an elastomer seal which is decided according to the elements like size, style and pressure rating.

Unions in general make available pressure-tight & constructive sealing for low-pressure services (1,000 to 2,000 PSI). The sphere-shaped exterior of the male sub and the angular exterior of the female sub lead to the formation of a metal-to-metal seal, which is further accentuated by the ball and the tangent. Unions range from 1 inch to 12 inches in the midst of freezing functioning pressures starting from 1,000 and going up to as much as 20,000 PSI.
