Cold Cutting Without Heat, Sparks or Risk
Abrasive cold cutting uses high-pressure water mixed with abrasive media to cut through steel, pipework and structural components — without heat, sparks or vibration.
This makes it the preferred method in environments where traditional hot works are unsafe or restricted, including petrochemical, COMAH and live processing facilities.
Designed for Live and High-Risk Environments
Abrasive cold cutting is deployed where safety and control are critical:
-
Petrochemical and COMAH sites
-
Refineries and chemical processing plants
-
Live pipelines and pressurised systems
-
Storage tanks and pressure vessels
-
Confined or restricted access environments
Enables cutting and access without introducing ignition risk or structural disturbance.
Controlled Access, Isolation and Removal
We use abrasive cold cutting to create safe, precise openings and separations within complex industrial environments:
-
Pipework and pipeline cutting
-
Pressure vessel access openings
-
Tank and containment entry cuts
-
Structural steel sectioning
-
Controlled removal of redundant plant
All works are planned and delivered to maintain safety, system integrity and site operations.
Part of a Controlled Demolition System
Cold cutting is rarely used in isolation.
It is often the enabling method that allows safe access for further controlled demolition:
-
Cut access → Robotic Demolition inside vessels or structures
-
Cut isolation points → Hydrodemolition or structural modification
-
Section steel → enable lifting, removal or internal works using Diamond Drilling & Sawing
This is where GNAT differs — methods are combined, not bolted on.
Project Examples in Live & Hazardous Environments
Why Abrasive Cold Cutting
