“Designed by the Oilfield, for the Oilfield”

SOUTHWEST MANUFACTURING INNOVATIONS is proud to offer a full line of wing Hammer Unions from Figure 100 to Figure 1502.

SOUTHWEST MANUFACTURING INNOVATIONS Hammer Unions are “Designed by the Oilfield, for the Oilfield”. Significant time was spent with oilfield suppliers and end users to gain an understanding of their requested changes and improvements that could be incorporated into a new line of Hammer Unions ideally suited for the oilfield. SOUTHWEST MANUFACTURING INNOVATIONS, then incorporated those requested changes for the purpose of developing the “Best of Breed” in wing Hammer Unions.

SOUTHWEST MANUFACTURING INNOVATIONS Hammer Unions are produced with a forging process as opposed to a casting process.

The Difference Between Casting & Forging:

Casting is the process where metal is heated until molten. While in the molten or liquid state, it is poured into a mold or vessel to create a desired shape.

Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state.

Why use forgings?

Forging offers uniformity of composition and structure. Forging results in metallurgical re-crystallization and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product particularly in terms of impact and shear strength. (In this case, strengthens the Hammer Union in terms of impact and shear strength.)

Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part.

The advantages of forging include:

  • Generally tougher than alternatives

  • Will handle impact better than castings

  • The nature of forging excludes the occurrence of porosity, shrinkage, cavities and cold pour issues.

  • The tight grain structure of forgings making it mechanically strong.

  • The tight grain structure offers great wear resistance without the need to make products “super-hard”.
