Liquid nitrogen pipe freezing equipment.
It utilizes liquid nitrogen in a controlled and automated system to safely and reliably freeze static liquids in a selected section of pipe or tubing.
The pipe freezing kit eliminates the need to drain systems and shut down operating equipment when making pipe repairs.
Jt equipment service brings today s latest technology we will freeze the piping using the patented accu freeze system the most advance pipe freezing system in the world.
Direct liquid nitrogen pipe freezing is the most common procedure used to establish isolation on a pressurised pipeline requiring the application of liquid nitrogen to the external surface of the pipe.
The standard accu freeze af1000 kit is used to create an in line ice plug capable of withstanding 2000 psi in pipes up to 12 inches in diameter.
The arctic freeze kit can freeze lines from 1 4 to 2 00 through 1 4 to 6 00.
Put simply pipefreezing is a non intrusive controlled method of providing pipeline isolation through the application of liquid nitrogen the pipework freezing process begins by drawing out the heat from the product within the pipe until it reaches a temperature below its freeze point until eventually the product freezes to form an internal ice plug.
The accu freeze kit af 1000 liquid nitrogen pipe freezing system can freeze lines up to 12.
Using liquid nitrogen or co2 to isolate the problem area in the pipeline by freezing the product inside the pipe to form one or more solid pipe freeze plugs.
The kit uses liquid carbon dioxide to create ice plugs in sections of pipes.
Hft pipestoppers accu freeze the controlled liquid nitrogen ln2 pipe freezing system is a method to freeze stationary liquids in a selected section of a pipe or tubing.
When an ice plug is formed the necessary modifications are made.
The freezing chamber is installed on the pipeline.
Pipe freeze services 1 2 36 pipe freezing is a non intrusive cost effective and quick method to perform pipeline modifications without draining the system.
Kits are supplied with three freezing jackets for pipes 4 13 77mm o d and two 20 hoses.
The chamber is sealed to the pipe with special tape to contain the liquid nitrogen that will be injected.
This transfers the low temperature liquid nitrogen through the pipe reducing the pipe fluid to a temperature below its freezing point and.
Using liquid nitrogen ift isolates your problem area in the pipeline or vessel by freezing the product inside the pipeline to form a solid plug.
The qwik freezer kit is a more commercial grade co2 pipe freezing system that can freeze lines single or dual 3 8 1 1 2 through 3 8 to 8 00.
Figure 1 left picture liquid nitrogen is injected and the pipeline monitored.
