Thermite

isol8’s Engineered Thermite Reaction Heaters – Safe, Controllable, Effective & Reliable

Safe 

API-RP67 compliant 

Two independent fail-safe barriers to prevent initiation 

isol8’s initiation device includes independent pressure and temperature switches that can be set to ensure thermite ignition cannot occur outside of the wellbore, compliant with API RP 67.

Exceptionally high ignition temperature

isol8’s proprietary thermite heater recipe has an exceptionally high ignition temperature, which serves as a built-in safety feature. Our thermite requires an external ignition source capable of reaching temperatures above 1,832°F (1,000°C), reducing the risk of accidental activation during handling and deployment. isol8’s heater recipes pass the UN screening test (5 minutes, 1000 °C ignition / V-block test) demonstrating that the thermite is NOT readily combustible. 

Proprietary ingredients mitigate hydrogen generation when wet

Isol8’s thermite passes the UN Dangerous Goods water reactivity test, producing less than 1 litre of flammable gas, per kg, per hour. 

Controllable, effective & reliable

• The thermite heaters can be surface, timer or motion activated. They can be deployed on slickline, digital slickline, electric wireline or pipe.
• No surface power is required to initiate the reaction. isol8’s dual initiation system provides redundancy and assured reliability.

Top-Down, Bottom-Up or Simultaneous Top-Down/Bottom-Up

isol8’s high expansion, bead deployment tool reacts from the bottom-up. The cast on heater toolstrings typically operate from the top-down. However, isol8 can also offer simultaneous bottom-up/top-down.
