The large storage tank bottom support ring is a critical load-bearing component for pressure vessels and
Heavy-duty Equipment in the
Petrochemical Industry. Designed exclusively to bear the self-weight of equipment, it does not come into contact with pressurized media, thus avoiding the risk of stress-induced deformation caused by medium pressure.
Manufactured via the
Ring Rolling process, this product is made of high-quality 42CrMo alloy steel and undergoes
Heat Treatment as well as high-precision machining. The annealing process effectively eliminates
Forging residual stress, ensuring exceptional structural stability and long service life under static load conditions. It serves as a reliable load-bearing foundation for large storage tank bottom support systems, providing stable support for heavy petrochemical equipment.
We implement a rigorous full-cycle manufacturing and quality inspection process as follows:
1.Incoming Material Inspection
2.Blank Cutting
3.Ring Rolling
4.Post-Forging Inspection
5.Heat Treatment: Normalizing → Annealing (Eliminate Forging Residual Stress)
6.Heat Treatment Inspection
7.Mechanical Property Testing
8.Precision Machining: Rough Turning → Semi-Finish Turning → Finish Milling
9.Comprehensive Inspection:
Dimensional & Geometric Tolerance Check
Non-Destructive Testing (Ultrasonic Testing, MT Magnetic Particle Testing)
Traceability Marking
10.Anti-Corrosion Treatment
11.Cleaning | Packing | Storage

Industry Applications
Our large storage tank bottom support ring is specifically optimized for heavy-duty static load scenarios in the petrochemical industry, with core applications including:
- Large Petrochemical Storage Tanks: Primary bottom support components for crude oil, chemical raw material, and finished product storage tanks
- Heavy Pressure Vessel Auxiliary Structures: Load-bearing bases for stationary pressure vessels that do not directly contact pressurized media
- Industrial Heavy Equipment Foundations: Stable support components for large-scale mixing equipment, separation devices, and reaction vessel auxiliary systems
Product Advantages
- Normalizing + annealing heat treatment completely eliminates forging residual stress, preventing deformation and cracking under long-term static load.
- Full-process inspection combined with advanced equipment (e.g., ultrasonic detector, coordinate measuring machine) ensures zero internal defects and dimensional compliance.
- Flexible customization of outer diameter (≤ 5m), width, thickness, and weight (≤ 9t) to match different tank specifications and load requirements.
- Professional zinc spraying and painting treatments extend service life in harsh petrochemical field environments.
