Introduction
Roben Manufacturing fabricates aluminum api tanks for operators who need API 650 or API 620 storage tanks built from aluminum for chemical compatibility, weight, cost, or regulatory reasons. Our shop maintains qualified welding procedures, certified welders, and full inspection capability for aluminum construction.
What Is Aluminum API Tanks?
Aluminum API Tanks are API-standard storage tanks fabricated from aluminum to take advantage of the alloy's specific properties — corrosion resistance, weight, temperature performance, or cost. Roben's aluminum api tanks carry the same API certification, ASME documentation, and National Board registration as our standard fabrications.
Why You Need Aluminum API Tanks
- Material Compatibility: Aluminum construction matched to the specific chemistry and operating conditions of your product service.
- Code-Stamped Construction: ASME Section VIII and API standards apply equally to all material grades — full traceability and documentation included.
- Service Life Optimization: Aluminum selection minimizes corrosion, scaling, and material loss over decades of operation.
- Total Cost of Ownership: Higher-grade materials often deliver lower total cost when corrosion allowance, coatings, and replacement intervals are factored in.
- Qualified Fabrication: Roben's qualified welding procedures and PQRs cover aluminum construction with full NDE documentation.
Specifications and Technical Characteristics
- Material Grades: 5083, 5454, 6061-T6, 3003 per service requirements
