Equalizing Prongs

In your downhole operation, the pressure is on to keep operations running smoothly and safely. An equalizing prong is run to allow pressure to equalize before pulling the plug running tool. To ensure the safety of your team, don’t take chances when it comes to your pressure equipment. The prong-type equalizing housing or assembly is the most commonly used method of sealing and equalizing across the set plug downhole and is often recommended for use where they may be debris present. Its function is to ensure that any pressure differential across the plug can be equalized prior to recovery. Usually a separate equalizing trip is made before pulling the plug tool on slickline, however, combined running tools and prongs are sometimes used and are routine when pulling the running tool on coil or drillpipe. 


Running and equalizing prongs are commonly screwed into running and pulling tools to perform functions necessary in manipulating subsurface devices. 

Equalizing Prong Applications

  • Wellheads
  • Hydraulic Fracturing
  • Service Trucks
  • Core Analysis
  • Mud Systems
  • Compressions Systems
  • Vapor Recovery Units

Equalizing prongs are designed to be set using a slickline toolstring. Prongs are set with a series of pulling, screwing and jarring actions. The mechanism puts stress on your slickline, wireline and tools to activate those tools’ settings. However, that stress can cause cracking, corrosion and kinks for inferior or worn slickline.

Central Wire Industries sells slickline to be used in conjunction with available equalizing prongs to reduce the chances of those failures. By following established usage guidelines throughout the life of your CWI GD™- SUPA® Slickline, you can protect against pressure-induced weak points or stress failures caused by other manufacturer’s defects. Regardless of the tool’s weight, the nominal sizing of the tube, the well pressure or temperature, our slickline are your best choice for consistent performance with equalizing prongs.
