At PTS, we are aware of the difficulties involved in maintaining pipeline systems, particularly in modifying live pipelines without interfering with operations. That is where our cryogenic pipe freezing services come in very handy. It is quick, effective, and non-invasive, enabling the isolation of the pipeline without draining or shutting down the entire system.
What Is Pipe Freezing?
One of the safest and economical ways to temporarily isolate a pipeline is called pipe freezing or cryogenic freezing. The process is done by forming a pressure-resistant ice plug using an external coolant, which is usually liquid nitrogen, on the pipeline. It is particularly suitable where valves are to be replaced, tie-ins and other remedial works are to be carried out without incurring major downtime or fluid losses.
Materials We Work With
At PTS, we provide pipe freezing services on all types of pipe material, such as:
- Carbon steel
- Stainless steel
Understanding Pipe Freezing and Its Benefits
There are numerous operational benefits of pipe freezing, especially in live conditions where system shutdown is not an option.
The major advantages of the Pipe Freezing Services are:
- Full drainage is not necessary, which saves time and minimises the waste of fluids
- The system remains online, and there is no necessity to shut down completely
- economical because of less labour and quick turnaround
- Faster operation, no refilling or purging is required
- Solutions that can be customised, e.g,site-specific jackets built to suit the constraints of a site.
Our Pipe Freezing Services
We have our, experienced engineers and stringent quality controls so we can provide cryogenic freezing solutions under the most challenging environments.
Application Focus: Hazardous Fluid Systems
Pipe freezing has proved to be a necessary solution to isolate dangerous or chemically aggressive pipelines, particularly when draining is not safe, environmentally friendly or cost-effective. We commonly apply cryogenic freezing of chiller lines and HVAC systems to allow valve replacements and tie-ins without process interruption or exposing workers to hazardous fluids.
Application Focus Live Modifications & Internal Inspections
Pipe freezing allows localised action in live systems where the ability to keep the system running is crucial. This enables clients to carry out internal checks, bypass lines or isolate defective areas safely and within a short time. Our freezing jackets are designed to be deployed quickly and to keep the full system pressure throughout the process, which reduces risk and downtime, keeping operations live.
Industries That Benefit From Pipe Freezing
Our pipe freezing services are reliable in many industries, such as:
- Transmission pipelines
- Data Centers
- Power generation
- Fire protection systems
- Office buildings
- Institutions and hospitals
- Shopping centres and malls
- Airports
- Hotels and apartment blocks
