So, What is Swaging?

Swaging is a cold forging process
where the dimensions of an item are altered using a die or dies.
Swaging is not the lining of a well by placing a slightly smaller casing inside a bigger one. In water well repair, our swaging tool employs steel jaws (dies) which exert up to 200 tons of force, fusing a steel sleeve to the existing casing. This process restores the casing back to its original shape, thickness & strength. Here are three common methods for swaging that we use in the repair of water wells:

I’ve Got Bad Water in the Upper Aquifer!
Years ago, before the intrusion of industry, farming, and population
growth, the quality of water from the primary aquifer was superior. One of the prices we all pay for progress is looking for better water in the deeper zones of a well. If a well has contamination in upper zones it should be sealed to stop the infiltration into the uncontaminated zones.

Our unique solution to this problem involves using a sealant on the outside of an expandable sleeve (see illustration). The sleeve is lowered and swaged out, bonding the sleeve to the casing. The sealant is sandwiches between the sleeve and the casing, filling any gaps. An additional sleeve is then swaged for reinforcement. The end result is a well that is free of transmission from a contaminated zone.

There’s a Hole in My Casing!
A small hole in a well can cause big problems. Holes can let in contaminates, debris, as well as adding “fill” to the bottom of a well. Small holes tend to not stay small holes. Formation material (sand and gravel) entering holes make them even larger. A dentist will fill a cavity to prevent the loss of a tooth. In the same way, a swage repair in a water well will prevent the potential loss of that well.

My Well Just Caved in!
A break in a well occurs when extraneous forces cause the metal in the casing to stress, fatigue, and then fail. Some of the common reasons for casing failure are ground subsidence (stove-piping), ground movement along fault lines, exterior voids or caverns collapsing due to formation erosion, or simply the toll from years of corrosion. Cave-ins are among the toughest well repairs. In the many years of dealing with these tough problems Welenco Water Well Technology has developed powerful swaging tools that can repair and reinforce these areas with thick strong casing making the well as good as a new.
