Your Trusted Partner for API Tanks and ASME Pressure Vessels
At Tate Metalworks, we build custom tanks and pressure vessels in every size and design. Projects that are around 14' and smaller in diameter are typically built at our facility in Roebuck, SC and delivered to your site ready for installation. Larger tanks and vessels are erected on-site at your location. We mobilize teams nationwide to provide industries with custom-built API tanks and ASME pressure vessels. We will work with you to find the best solution for your process. Limited access due to existing equipment or buildings, time constraints, or last-minute changes to nozzle locations are obstacles we have dealt with many times. We are ready to work with you whatever your challenges may be, and we have a proven track record of success.

API 620 Tanks
API 620 tanks offer the advantage of storing products at elevated pressures and reduced temperatures compared to API 650 tanks. Industries that commonly utilize API 620 storage tanks include chemical, agro chemical, pulp & paper, biofuels, petrochemical, waste water treatment, and cryogenic storage.
Common Configurations
In addition to the structural features below, API 620 storage tanks can be designed with accessories such as insulation support, ladders, spiral stairs and platforms to optimize its design to fit your space and operations.
- Flat Bottom Tanks: Ideal for maximizing storage capacity and cost-effectiveness
- Cone Bottom Tanks: Perfect for efficient drainage and easy cleaning
- Dished Head: Efficient for containing pressure while optimizing internal volume & material usage
- Umbrella Roof: Economical option that provides water drainage and vapor space
- Flat Roof: Cost-effective solution that is easy to access for maintenance and inspection
Common Applications
- Cryogenic liquid storage of oxygen, hydrogen and ammonia
- Liquefied Natural Gas (LNG)
- Liquefied Petroleum Gas (LPG)
- Biogas
- Specialty Gases
- and more!
API 620 tanks are best for:
- Low-pressure storage (up to 15 psi)
- Suitable for liquids stored at temperatures up to 250°F (121°C)
- Typically for large-diameter tanks that are often field-erected
- Storage of a large volume of liquids in excess of 5 million gallons
- Various shapes beyond just vertical cylindrical tanks and horizontal tanks like silos and cone bottom tanks and dished head roofs
API 653 Standard Repair & Reconstruction
API 653 plays a critical role in ensuring the integrity and longevity of your above-ground storage tanks. At Tate Metalworks, we specialize in providing expert API 653 tank repair and reconstruction, with a focus on bottom, shell, and roof replacements. Our services ensure that your storage tanks remain compliant with industry standards while minimizing downtime and extending the life of your assets.
ASME Pressure Vessels & Reactors
Tate Metalworks’ ASME pressure vessels are engineered for excellence, meeting the highest safety and quality standards outlined in ASME Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code.
Industries where ASME pressure vessels are most commonly found for product processing include chemical, agro chemical, advanced recycling, biofuels, petrochemical, pulp & paper, bioplastics, renewable natural gas (RNG), pharmaceutical, coatings, and foam.
Common Configurations
In addition to the structural features below, ASME vessels & reactors can be designed with accessories such as insulation support, ladders, spiral stairs and platforms to optimize its design to fit your space and operations. Furthermore, half pipe jackets, dimple jackets and internal coils can be included depending on your processing needs.
- Flanged & Dished Head: A common, yet versatile, choice for pressure vessels
- 2:1 Elliptical Head: Elongated shape that is good for handling internal pressure
- Hemispherical Head: Strongest shape and ideal for high pressures
- Leg Supported Bottom: Economical for smaller vessels with easy access underneath
- Skirt Supported Bottom: Distributes weight evenly, which is ideal for large vessels
- Half-Pipe Jackets: Simple yet efficient for heating or cooling
- Dimple Jackets: Larger surface area for enhanced heat transfer
Common Applications
- Pressure vessels
- Reactors
- Reactor vessels
- Pyrolysis reactors
- Bioreactors
- Distillation columns
- Jacketed tanks
- OEM vessels
- Reactor vessels
ASME pressure vessels are best for:
- High pressure storage up to 3,000 psi
- Suitable for processing liquids at temperatures in excess of 800°F (427°C) and more depending on the metallurgy
- Suitable for shop built vessels to large field erected columns and towers over 100 feet in height.
- Best for vertical or horizontal cylindrical tanks with dished bottoms and top heads and either leg or skirt supported.
