Product Description
Welded Waste Oil Storage Tanks
Engineered for leak-proof containment of lubricants, hydraulic fluids, and machining coolants with superior environmental compliance.
Superior Welded Construction
Seamless welded integrity prevents leaks, with modern submerged arc welding (SAW) creating joints with less than 0.1% porosity, exceeding API 650 standards for hazardous liquid storage.
Key Advantages
- Pressure Resistance: Withstand 2.5-4X more internal pressure than bolted equivalents (tested to 30 PSI)
- Customization: On-site welding allows integration of baffle walls, heating jackets, and multi-chamber configurations
- Lifespan: 25-40 year service life vs. 10-15 years for polyethylene tanks
- Regulatory Compliance: Meets EPA 40 CFR 264.193 requirements for secondary containment
- Recyclability: Steel tanks offer 90%+ scrap metal value vs. landfilling costs for plastic
Material Selection Guide
| Material | Thickness Range | Corrosion Resistance | Temp Limit | Cost Index |
|---|---|---|---|---|
| Carbon Steel (ASTM A36) | 3/16" - 1/2" | Moderate (needs coating) | 800°F | 1.0 |
| 304 Stainless Steel | 1/8" - 3/8" | Excellent | 1500°F | 3.2 |
| Duplex 2205 | 3/16" - 1/2" | Superior (chloride resistance) | 600°F | 4.8 |
| Corten Steel | 1/4" - 1" | Atmospheric corrosion | 750°F | 1.7 |
Advanced Welding Technologies
- Automated GMAW (MIG) Systems: Achieve 15% thicker weld deposits than manual welding
- Real-Time Weld Monitoring: Detect flaws down to 0.005" during fabrication
- Robotic Circumferential Welders: Ensure ±0.5° angular accuracy in cylindrical tank assembly
Maintenance & Inspection
Annual Inspections: Ultrasonic testing for wall thickness and dye penetrant testing on welds
Coatings: Coal-tar epoxy for acidic oils, zinc-rich primers for coastal environments
Upgrades: IoT-enabled pressure sensors and explosion-proof vents for flammable oils

Frequently Asked Questions
How does welding affect tank certification?
Welded tanks require ASME Section VIII Division 1 certification for pressures above 15 PSIG. Always request mill test reports (MTRs) for materials.
What's the lead time for custom welded tanks?
8-14 weeks for engineered systems, depending on size (standard 5,000-50,000 gallon capacity).
Are welded tanks earthquake-resistant?
When designed per API 650 Appendix E, they withstand seismic zones up to Zone 4.
