DISPOSABLE SERIES
Disposable CO2 Fracturing Tube
Single-use gas expansion fracturing tubes for safe, efficient, and regulation-free rock fragmentation. No detonation, no shock wave, no permits required.
Why Choose Disposable CO2 Fracturing Tubes?
Contained chemical reaction generates high-pressure gas for rock breaking — no detonation, no open flame, no hazardous emissions
Extreme Safety
No spark, no arc, no flame. Impact, friction, and static electricity cannot trigger detonation. CO2 is inert – no risk of gas explosion in coal mines.
Eco-Friendly
Only CO2 released as primary gas (acts as flame retardant). No toxic gases (CO, NOx), minimal dust, low noise. Fully compliant with environmental regulations.
Cost Effective
No explosive permits, no specialized storage, no professional guards needed. Operating costs reduced by 30%+ compared to traditional blasting. Simple training sufficient.
Fast & Efficient
Fracturing completes in 4 milliseconds. No misfire, no post-blast inspection needed. 9V low-voltage initiation with 2000V external firing device.
Directional Control
Fracturing direction is controllable. Supports delayed initiation. Energy levels adjustable based on rock hardness and project requirements.
No License Required
Not classified as explosives. No blasting license needed. Easy transport and storage. No special security personnel required.
How It Works
Resistance Test
Measure tube resistance with tester. Ensure value is within standard range (tolerance: ±0.5Ω).
Wiring
Connect tubes in series. Use 0.5mm² copper wire for branches, 1mm²+ for main line. Seal joints with waterproof tape.
Loading
Insert tube with lead end facing hole bottom. Leave ≥30cm outside. Backfill with fine gravel (1-2mm) then larger gravel (3-5mm) to seal the hole tightly.
Initiation
Personnel evacuate to safe distance (≥50m). Safety officer sounds alarm. Blaster charges to >2000V and fires on countdown.
Ventilation
After fracturing, ventilate continuously. Enter work area only after gas detection confirms safety.

Technical Highlights
4ms Instant Response
Upon electrical initiation, the internal chemical compound reacts within 4 milliseconds, generating a large volume of high-pressure gas (primarily CO2) that expands to fracture rock. Energy is released precisely when and where needed.
9V Low-Voltage Initiation
Compatible with standard high-voltage initiators (2000V+). Simple series or series-parallel wiring connection. No specialized blasting equipment required. Operators can be trained within hours.
PPR Tube Material
High-strength PPR construction with pure copper wire leads (0.55mm²). Extended 15mm wire connection for reliable field operation in all conditions.
Zero Sensitivity
Certified by national authorities with zero sensitivity to impact, friction, flame, and static electricity. The safest rock breaking method available today.
Frequently Asked Questions
What is a disposable CO2 fracturing tube?
It is a single-use sealed PPR tube containing an internal chemical compound (gas-generating agent) and an electric match. When electrically initiated, the compound reacts rapidly within milliseconds, generating high-pressure gas (primarily CO2) that expands and fractures the rock. The tube ruptures during the process and is not reusable.
How is it different from reusable CO2 fracturing systems?
Reusable systems use steel tubes that can be recovered after each blast (up to 5000+ uses). Disposable tubes are single-use – simpler logistics, no recovery needed, lower per-use cost, and eliminates the safety risk of “flying tubes” during operation.
Do I need a blasting license to use these tubes?
In most jurisdictions, CO2 fracturing tubes are NOT classified as explosives. No blasting license, specialized storage, or transport permits are typically required. However, always verify local regulations before use.
What is the minimum order quantity?
We accept orders from as low as 100 pieces per model. Bulk discounts available for orders over 1,000 pieces. Contact us for custom pricing based on your project requirements.
Can it be used in underground coal mines?
Yes. The primary gas generated by the internal chemical reaction is CO2, which is inert and actually suppresses combustion, making these tubes safe for use in low-gas coal mines where traditional explosives pose explosion risks. Always follow mine safety protocols.
