Applications of Piping Materials in Oil and Gas

Upstream Operations

• Carbon steel is widely used for drilling and production pipelines.

• Composite materials are ideal for deepwater operations.

Midstream Operations

• High-pressure pipelines transporting crude oil or natural gas typically use alloy steel.

• HDPE is suitable for short-distance and temporary transport systems.

Downstream Operations

• Stainless steel is prevalent in refineries due to its resistance to corrosive byproducts.

• Copper-nickel alloys are essential for heat exchangers and cooling systems in processing plants.
