Frequently Asked Questions

About Pipe Freezing  

 

What is Pipe Freezing? 

 

Pipe Freezing, or freeze plugging, is a method used to isolate sections of a liquid filled pipe system, while 

maintaining pressure throughout. It is also used to minimize draining expensive fluids, or having to backfill 

systems, which can cause additional problems to develop.   

 

Certain system criteria must be met when performing a Pipe Freeze application.  Sub-Zero Pipe Freezing Services provides a simple questionnaire to help gather all the information required to properly quote and execute any Pipe Freezing project.  We also take the information over the phone to further provide customer convenience. 

 

Below is an example of the information our questionnaire will ask, so that we can properly respond to a client's needs:

 

  • Pipe Size(s)

  • Number of Freeze Plugs

  • Fluid Type(s) 

  • Temperature(s)

  • No Flow Condition Required

  • Freeze Location(s)

  • Additional Information...

What are the Benefits of Pipe Freezing? 

 

Pipe Freezing is a quick solution to keep labor costs and system down-time to a minimum. 

 

  • It Is Cost Effective; Saves Time And Money

  • Isolates Work Area - Allowing The Rest Of The System To Remain Active.

  • Allows Control of Hazardous Fluids

  • Avoids Costly Drain-downs

  • Complete Shutoff: No Leak-By. Ideal For Soldering or Welding
