Pipeline Lamination Effect On Freeze Plug

To accomplish the freeze a jacket cryogenic.

Pipeline lamination effect on freeze plug.

Tests have been carried out with plugs holding in excess of 8 000 psi. This means that the ice cracks and fills with water re freezes cracks and so on until a plug is created. Once the freeze plug is set we are able to determine which side the leak is on eliminating half the pipeline. The pipe freeze is a controlled process where the ice that is created is very brittle due to the very cold temperature.

Freeze plugs can also be used to locate small leaks during hydrotesting by reducing the length of pipeline by half with every isolation. Koppl pipeline services method of pipe freezing sometimes causes concern to those individuals that have dealt with ruptured piping due to freezing. The pipe freeze plug expands along the length of the pipe and the result is stress free ice. 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 ice pipe freeze plugs.

Pipe freeze plug technology is a simple cost effective method to perform pipeline maintenance or modifications without draining. Ruptures occur when the ice plug forms expands and causes pressure to build between the plug and a dead end. Is it the cryogenic effect on the piping material that is actually responsible for such a pipe failure. This allows for very little drain down or refill having to bleed problematic air out of pipes during refills and in many cases no system downtime.

The pipe ruptures when the pressure builds beyond its designed pressure rating. When water freezes within piping it develops an internal freeze plug which grows outward in both directions of the pipe id. 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. Pipe freezing is a non intrusive cost effective and quick method to perform pipeline modifications without draining the system.
