01What Is API 650 Tank

API 650 is the global universal standard for atmospheric vertical welded steel storage tanks. It is the most widely accepted specification for oilfield tank farms, refineries, petroleum terminals and industrial crude oil storage projects worldwide. All our tanks are fully designed and fabricated strictly according to API 650 latest edition, meeting international bidding and project acceptance requirements.

02API 650 Tank Types

We provide full series API 650 vertical storage tanks for large oil storage projects:

1. API 650 Fixed Roof Tank

Ideal for fuel oil, heavy oil and low-volatility petroleum storage. Stable structure, low maintenance cost, widely used in auxiliary tank farm areas.

2. API 650 Internal Floating Roof Tank (IFR)

Best choice for crude oil storage. Greatly reduces oil vapor loss, prevents explosion risk, improves storage safety, the mainstream type for large oilfield tank farms.

3. API 650 External Floating Roof Tank (EFR)

Applied for super-large capacity crude oil tanks above 10,000m³, ultra-low volatilization, suitable for refinery and central oil depot projects.

08API 650 FAQ

Q1What is the difference between API 650 and API 620?

API 650 is for atmospheric storage tanks, the standard choice for conventional crude oil tank farms. API 620 is for low-pressure large storage tanks for special mediums.

Q2Are your tanks fully API 650 certified for overseas bidding?

Yes. Every design, fabrication and testing procedure strictly complies with API 650 latest standard, with complete English document set for project review and customs clearance.

Q3Can you customize API 650 floating roof tanks?

We provide full API 650 fixed roof, internal floating roof and external floating roof customization for all 1000m³+ large tank projects.

Q4How do you guarantee API 650 quality?

We adopt API 650 standard structural calculation, automatic welding and 100% NDT inspection, strictly follow standard wall thickness and safety configuration.
