Roben, Mfg, Inc. is a leading manufacturer of API tanks, specializing in the design, fabrication, and supply of high-quality tanks that meet the stringent standards set by the American Petroleum Institute (API). With our expertise and state-of-the-art manufacturing facilities, we deliver reliable and efficient API-certified tank solutions that meet the most demanding requirements across various industries.
What is an API Tank? An API tank is a storage container designed and constructed according to the standards set by the American Petroleum Institute. These tanks are primarily used for storing petroleum, petrochemical products, and other liquids in the oil and gas industry. API tanks ensure safe storage and handling of these materials while adhering to internationally recognized standards.
We utilize advanced tank design software and follow rigorous quality control procedures to ensure compliance with API standards.
1. What is the difference between API 650 and API 620 tanks?
API 650 tanks are designed for atmospheric storage of liquids, while API 620 tanks are for low-pressure storage of liquefied gases with vapor pressures up to 15 psig.
2. How often should API tanks be inspected?
Inspection frequency depends on the tank’s service, but generally, external inspections are recommended monthly, with internal inspections every 5-10 years as per API 653 guidelines.
3. What is a floating roof tank, and when is it used?
A floating roof tank has a roof that floats on the surface of the stored liquid, reducing vapor space and emissions. It’s commonly used for storing volatile liquids like gasoline.
4. Can API tanks be repaired or modified?
Yes, API tanks can be repaired or modified according to API 653 standards. This work should be performed by qualified personnel with appropriate certifications.
5. What safety features are required for API tanks?
Common safety features include overfill protection systems, emergency vents, fire-fighting systems, leak detection systems, and grounding for static electricity dissipation.
6. How long do API tanks typically last?
With proper maintenance and corrosion protection, API tanks can last 30 years or more. Regular inspections and maintenance are crucial for maximizing lifespan.
7. What is the maximum size for an API 650 tank?
API 650 does not specify a maximum size, but practical limits are typically around 300 feet in diameter and 80 feet in height, depending on design parameters.
8. How do I choose the right API tank for my application?
Consider factors such as the product to be stored, required capacity, operating conditions, local regulations, and site constraints. Consult with a qualified tank manufacturer or engineer for the best selection.
9. What is the purpose of a tank foundation in API tank construction?
The foundation provides a stable base for the tank, distributes the load evenly, and helps prevent settlement that could cause tank deformation or damage.
10. Are there environmental regulations specific to API tanks?
Yes, API tanks are subject to various environmental regulations, including EPA’s Spill Prevention, Control, and Countermeasure (SPCC) rules and emissions control requirements under the Clean Air Act.
