DESIGN YOUR CUSTOM VACCUM RATED STAINLESS STEEL VESSEL
Engineered for Full Vacuum & Pressure Integrity
At EIC Tanks, we design and manufacture vacuum rated stainless steel vessels engineered to withstand internal vacuum conditions without structural failure or deformation.
Vacuum service introduces compressive stresses that standard storage tanks are not designed to handle. Improperly engineered vessels can collapse under full vacuum conditions, creating safety risks and costly downtime.
Our vacuum-rated vessels are structurally reinforced and mechanically designed to maintain integrity under:
• Full internal vacuum
• Combined vacuum and pressure cycles
• Heated vacuum applications
• Agitated vacuum processing
Each vessel is engineered based on your specific operating conditions.
WHY VACUUM RATING REQUIRES SPECIALIZED ENGINEERING
Unlike positive pressure, vacuum service places compressive stress on the vessel shell. This requires careful calculation of:
• Shell thickness
• Stiffening rings
• Head design
• Nozzle reinforcement
• Agitation loads under vacuum
Our engineering team evaluates external pressure design requirements in accordance with ASME Section VIII Division 1 when applicable. We ensure the vessel will not buckle or deform during full vacuum operation.
ASME VACUUM PRESSURE VESSEL CONSTRUCTION
When required, we fabricate ASME-certified vacuum pressure vessels designed for external pressure conditions. Our vacuum vessels can be built for:
• Full vacuum service (29.92 inHg)
• Combined pressure and vacuum ratings
• Jacketed vacuum applications
• Temperature-controlled vacuum processing
Each code-stamped vessel can be supplied with National Board registration and supporting documentation.
VACUUM MIXING & PROCESS APPLICATIONS
Vacuum vessels are commonly used for:
• Deaeration
• Solvent removal
• Controlled atmosphere processing
• High-viscosity blending
• Pharmaceutical and cosmetic production
When agitation is required, we calculate torque and motor sizing to account for operation under reduced pressure conditions. Available configurations include top-entry mixers, anchor agitators, sweep systems, and high-shear assemblies engineered specifically for vacuum environments.
Jacketed & Heated Vacuum Vessels
Many vacuum processes require precise temperature control. We offer jacketed vacuum vessels with:
• Steam heating
• Hot oil systems
• Conditioned water cooling
• Zoned thermal control
The vessel shell and jacket are engineered together to withstand both vacuum and heating stresses simultaneously.
OUR STEP-BY-STEP VACUUM VESSEL ENGINEERING PROCESS
1. Process & Operating Condition Review
We review your maximum vacuum level, operating temperature, agitation requirements, and compliance standards.
2. External Pressure Design Calculations
Our engineers perform external pressure calculations to determine shell thickness, reinforcement spacing, and head design.
3. Approval Drawings
You receive detailed approval drawings outlining vessel dimensions, reinforcement placement, nozzle configuration, and support structure. Fabrication begins only after approval.
4. Fabrication & Quality Control
Our fabrication team welds and assembles the vessel under strict quality standards. Reinforcement integrity and dimensional accuracy are verified throughout production.
5. Final Inspection & Documentation
Each vessel undergoes inspection prior to shipment to confirm compliance with engineering and code requirements.
CUSTOM OPTIONS & INTEGRATED CONTROLS
Vacuum-rated vessels can be equipped with:
• Vacuum-rated sight glasses
• Vacuum relief valves
• Load cells
• Temperature probes
• CIP spray systems
• Insulated cladding
• Explosion-proof motors
• PLC control panels
• Custom discharge valves
All accessories are selected to maintain vacuum integrity and operational reliability.
BUILT FOR STRUCTURAL RELIABILITY & LONG-TERM PERFORMANCE
Vacuum conditions demand precision engineering and structural reinforcement. Our vessels are designed to prevent collapse, deformation, and fatigue over repeated operating cycles. EIC Tanks delivers vacuum-rated stainless steel vessels built for real-world processing environments where safety and performance cannot be compromised.
