In the petrochemical industry, oil pipeline steel pipes play a crucial role in transporting crude oil, gas, and chemicals from extraction wells to refineries, as well as for product distribution and storage. Key criteria for these products include superior durability, resistance to corrosion in marine and chemical environments, high-pressure tolerance, and extended longevity, all of which contribute to optimizing operational costs and enhancing safety.
Common Types of Oil Pipeline Steel Pipes in the Petrochemical Industry
The selection of common oil pipeline steel pipes in the petrochemical industry today is based on manufacturing materials, production technology, and international technical standards.
Carbon steel, alloy steel, and stainless steel are the three primary material groups that meet the demands of demanding operational environments, such as offshore extraction, petrochemical processing, and high-pressure fuel transport.
Carbon Steel Pipe
- Advantages: Carbon steel pipe are known for their strength and durability. They’re ideal for high-pressure environments and are commonly used in refineries and transportation pipelines.
- Applications: Transporting crude oil, natural gas, and water in upstream, midstream, and downstream operations.
Stainless Steel Pipe
- Advantages: Stainless steel offers excellent resistance to corrosion, making it a popular choice in environments with high moisture or chemical exposure.
- Applications: Ideal for offshore drilling platforms and areas prone to corrosive substances.
Alloy Steel Pipe
- Advantages: Alloy steel contains added elements like chromium and molybdenum, enhancing its heat resistance and durability.
- Applications: High-temperature environments such as those found in power plants and processing facilities.
The two most common product lines are welded steel pipe and seamless steel pipe.
Welded steel pipes are suitable for large-scale pipeline systems at a reasonable cost, while seamless steel pipes offer superior durability, leak resistance, and excellent pressure resistance.
Additionally, galvanized steel pipes provide enhanced chemical corrosion resistance, extending their service life when installed in outdoor projects, offshore pipelines, or saline environments.
International standards such as API 5L (for oil and gas pipelines), ASTM, and quality management certifications like ISO 9001 and ISO 3834-2, along with AISC regulations, are mandatory benchmarks in the production and operation of oil pipeline steel pipe systems.
API 5L steel pipes are carbon steel pipes used for oil and gas transmission. They include pipes manufactured in seamless and welded (ERW, SAW). The grades include API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services.
