Petroleum and Process Industries
Superior performance in supercold environments makes Alcoa aluminum an ideal material for handling fluids such as liquified natural gas (LNG) efficiently, safely and economically. Its excellent mechanical properties at cryogenic and ambient temperatures, combined with superior corrosion resistance, make it attractive for applications such as LNG tankers or storage tanks.
Wider Alcoa aluminum requires fewer plates for welded structures, reducing the number of welded joints and lowering fabrication costs. For example, LNG tank domes can be spun formed from one Alcoa plate circle up to 197 in. (5.00m) in diameter.
Alcoa aluminum is used in a variety of petroleum and process industry applications including:
- Oil and gas field machinery and equipment
- Cryogenic process and gas manufacturing and storage equipment
- Equipment for nuclear, fuel, coal gasification, ocean thermal fusion and geothermal requirements
- Petroleum refinery machinery and equipment
- Chemical industry (including plastics) machinery and equipment
- Food, dairy products and beverage industry machinery and equipment
- Water treatment, including desalting and sewage treatment machinery and equipment
Examples of aluminum structures include:
- Prilling towers
- Storage tanks
- Heat exchangers
- Blenders or mixers
- Scrubber towers
- Cooling towers
Alcoa aluminum’s light weight and superior corrosion resistance make it a star performer in the marine industry. When designed into ocean-going yacht and ship structures, aluminum is one of the most cost effective materials available. Its lighter weight improves weight distribution, expands equipment capacity, increases payload, improves stability, decreases displacement and facilitates ship design and operation. Size for size, ocean-going aluminum yachts are stronger, faster, and more fuel efficient because of aluminum’s high strength-to-weight ratio. Lightweight aluminum materials are essential to naval combatant ships because of the expanded use of on board electronics hardware and damage control equipment. Aluminum also increases speed and improves maneuverability. For LNG ship construction, aluminum has the additional advantage of higher strength and ductility at cryogenic temperatures.
Alcoa aluminum is used for a variety of marine applications:
- Commercial ship and boat construction and repair
- Surface effect ships and air cushion vessels
- Naval and coast guard ship and boat construction and repair
- Commercial LNG ship construction, equipment and repairs
- Hydrofoil vessels
- Other non-recreational water transportation equipment
- Super structures and hulls on cruise ships and ferry boats
- Hulls for ocean-going yachts and fishing or work boats, especially for drilling and operating offshore oil and gas wells
