Product Description
The B4C-HV80-14 represents the pinnacle of industrial blast nozzle engineering. With an 80mm extra-long venturi profile and a massive 14mm orifice, this nozzle is designed for the largest compressors (900-1600 CFM) used in shipyard, petrochemical, and pipeline surface preparation operations. Manufactured from premium hot pressed boron carbide, it delivers 400-600 hours of continuous service life under the most demanding conditions.
After extensive comparative testing of all commercially available nozzle materials under identical high-volume blasting conditions (G25 steel grit, 110 PSI, 1200 kg/hr flow rate), hot pressed B4C demonstrated the following wear life advantages:
| Material | Average Wear Life (Hours) | Relative Life |
|---|---|---|
| Hot Pressed B4C (WNRLN B4C-HV80-14) | 400-600 | 12x baseline |
| Silicon Carbide (SiC) | 80-120 | 2.4x baseline |
| Tungsten Carbide (WC-Co) | 40-60 | 1.2x baseline |
| Reaction Bonded SiC | 30-50 | 1x baseline |
| Alumina (Al₂O₃) | 15-25 | 0.5x baseline |
| Cast Iron / Hardened Steel | 3-8 | 0.1x baseline |
For a shipyard operating two 1200 CFM compressors on double shifts (16 hours/day), the annual nozzle cost comparison is striking:
- B4C nozzles: ~12 replacements/year at $60/unit = $720/year per blast station
- SiC nozzles: ~60 replacements/year at $35/unit = $2,100/year per blast station
- WC nozzles: ~100 replacements/year at $50/unit = $5,000/year per blast station
Beyond the direct savings, reduced nozzle change downtime (15 minutes per change) recovers approximately 20 productive blasting hours per year per station when using B4C nozzles, worth thousands in labor and equipment utilization.
Each B4C-HV80-14 undergoes ultrasonic inspection for internal defects, laser bore profilometry for dimensional verification, and a documented hardness test before shipping. Every nozzle is serialized and comes with a material certification report.
