Pipeline Freezing

Often, hotels and shopping centers are required to modify or repair certain air duct/water pipelines in the building without shutting off the main valve.

We shall propose the best solutions for our customers so as to provide minimum disruption to customers’ operations and at the same time complete the project smoothly.

Pipeline Freezing

Simply put, is a control method for isolating pipes, through application through Pipeline Freezing. Pipeline freezing begins by drawing heat away from the product in the pipe until it reaches a temperature below freezing. Until the product solidifies to form an ice plug inside.


Tube freezing method?

Pipeline freezing typically involves the use of liquid nitrogen during a controlled solid ice formation in the pipeline. Once the freezing state is reached, it is capable of withstanding very high differential pressures and provides extremely effective reliable isolation, allowing changes to be completed without draining all the water.

In what cases is pipe freezing applied?

  • Valve settings
  • Replace the tube part
  • Device isolation
  • Terminate the pipeline branch
  • Pipe redirection
  • Bypass the pipe
  • Metering Settings

What materials are pipes usually made of?

  • Carbon steel
  • Nickel alloy
  • Copper-based alloys
  • Kunifer
  • Aluminum alloy
  • Stainless Steel
  • Ductile and cast iron

What kind of products are pipes usually used for?

  • Country
  • Acid
  • Coolant
  • Paint
  • Alcohol
  • Oil
  • Liquid food products
  • Chemicals
  • Wastewater
  • Applications of pipe freezing service
  • Cooling water
  • Fire protection system
  • Processing system
  • Fuel oil series
  • Mud Road
  • Hydraulic control line
  • Water system
  • Hydrocarbon risk
  • Water spray line
  • Heat exchanger line
  • Heating Service
  • Cold water system

What are the benefits of freezing pipes?

  • Pipeline freezing is widely acknowledged as a safe, reliable and highly cost effective method of temporary pipeline isolation and offers a number of key benefits, some of which are: –
  • No drainage is required, thus avoiding costly and time-consuming venting procedures
  • No need to arrange for bulk transfer/liquid storage
  • Cuts loss of expensive fluids, such as treated water and system inhibitors.
  • Fix hazardous material handling problems and increase safety when working on lines containing contaminated or volatile liquids.
