Frequently Asked Questions
What is Pipe Freezing
Pipe Freezing is a method that uses an ice plug to temporarily block a section of a pipeline, allowing maintenance or modifications without draining the entire system.
What are different Pipe Materials and Fluids that Can Be Frozen?
Pipeontec commonly work with materials like carbon steel, stainless steel, and copper alloys. It’s effective for fluids such as Chiled water, Cooling water, Crude oil, Bolier Feed Water, Sea Water and water based fluids and chemicals.
How Long Does It Take to Form an Ice Plug?
The freezing time varies with the pipe diameter. Small pipes upto 4″ can be frozen less than an hour however large sizes in the range 20″ or above can take upto 12hour to freeze.
What Industries Use Pipe Freezing?
The service is widely used in Utility markets, District cooling networks, Oil and gas industry, Offshore and Onshore Well heads etc.
Advantages of Freezing over Other Isolation Methods?
Pipe Freezing is often faster and more cost-effective option than conventional methods like shut-down and system draining, especially in complex systems that do not allow system shut down.
What is the Pipe Temperature Required for Freezing?
The exact temperature depends on the fluid and pipe material, but typically, temperatures below -20°C (-4°F) are needed to form a reliable ice plug.
How Is the Ice Plug Removed After the Repair Done?
The ice plug is allowed to thaw (melt) naturally, restoring normal flow through the pipeline without additional additives. Controlled heating option is available for rapid restoration of pipeline operation.
Can Pipeontec’s Be Used for Emergency Repairs?
Yes, Pipeontec’s is an excellent option for emergency repairs where immediate isolation is needed without shutting down the entire system.
Does Pipeontec’s Affect the Integrity of the Pipe?
No, when done correctly,Pipeontec’s does not damage the pipe. The process is controlled to ensure that the pipe’s structural integrity is maintained.
