Steel Structure Engineering of China National Petroleum and Natural Gas First Construction Company

Petroleum steel structure engineering involves the design, fabrication, and construction of steel structures used in the exploration, extraction, processing, storage, and transportation of petroleum and its by-products. These projects play a critical role in the energy sector, supporting the infrastructure needed for safe and efficient petroleum operations.

Design Considerations

Load and Stress Analysis:

Dead loads (weight of the structure).

Live loads (equipment, personnel, and dynamic operational forces).

Environmental loads (wind, waves, and seismic activity).

Corrosion Resistance:

Use of corrosion-resistant steel (e.g., CORTEN steel).

Protective coatings (epoxy, galvanization, or cathodic protection).Temperature Resistance:

Design for high and low temperatures in processing and cryogenic storage.

Fire Safety:

Fireproofing steel with spray-applied coatings or encasing in concrete.

Material Standards:

Compliance with codes like API (American Petroleum Institute) and ASME standards.

Benefits of Steel in Petroleum Projects

Strength-to-Weight Ratio:

Essential for supporting heavy loads while minimizing material use.

Fabrication Flexibility:

Prefabrication allows faster construction and precision.

Durability:

Resistant to harsh environments with proper treatments.

Modularity:

Simplifies transportation and installation in remote or offshore locations.
