02Oil Tank Type Classification

We provide standardized & customized large oil tanks in multiple types, fully compliant with corresponding API standards, covering all large-volume industrial storage scenarios.

1. Vertical Storage Tank (API 650 / API 620)

Mainly used for large-scale oil depot and refinery storage projects above 1000m³. Includes fixed roof tank, internal floating roof tank, external floating roof tank and dome roof oil storage tank. Features large storage capacity, low volatilization and safe, stable operation.

2. Horizontal Pressure Tank (API 650 / API 620)

Applicable for special terrain and low-pressure large-volume petroleum storage. Compact structure, good pressure resistance and flexible installation — suitable for auxiliary storage and segmented large-capacity storage projects.

3. API 12D Field Tank

Customized for outdoor oilfield field operation scenarios, with strong environmental adaptability and simple, reliable structure — specially designed for on-site crude oil temporary and fixed storage in oilfield sites.

06FAQ

Q1What tank types and capacities can you customize?

We specialize in 1000m³–100,000m³ large oil tanks, supporting custom vertical fixed roof, dome roof, internal/external floating roof tanks and horizontal pressure oil tanks. All products comply with API 650/620/12D standards to match large-scale industrial oil storage needs.

Q2Do your tanks meet API 650 international standard?

Yes. All design, fabrication and testing strictly follow API 650, including our dome roof oil storage tanks — fully applicable to overseas oilfield and bidding projects.

Q3How to solve the transportation problem of large tanks?

We adopt split plate pre-fabrication (including split manufacturing of large dome roof components), pack with standard containers, effectively reducing logistics cost and avoiding oversize transportation restrictions.

Q4What’s the difference between API 650, API 620 and API 12D tanks?

API 650: standard atmospheric vertical storage tank (including fixed roof, floating roof and dome roof tanks) for conventional crude oil tank farms. API 620: designed for low-pressure large-volume storage scenarios. API 12D: professional field tank for on-site oilfield storage, fully customizable per project requirements.

Q5Do you provide on-site installation abroad?

Yes. We provide overseas on-site assembly, welding, testing and one-stop turnkey service for all tank types including dome roof oil tanks.

Q6What are the advantages of dome roof oil storage tanks?

Our API 650 compliant dome roof oil storage tanks adopt integral arched roof design without internal supports, featuring higher structural stability, strong wind/snow/impact resistance, good overall tightness, low oil gas volatilization, and no roof water or dust accumulation. They are more durable and require lower maintenance costs than traditional fixed roof tanks — ideal for harsh outdoor and high-standard petrochemical storage projects.
