Oil Gas Industry API 5L PSL2 Petroleum Steel Pipe
API 5L PSL1 X65 is a kind of seamless steel pipe for oil pipeline, which is mainly used to transport oil and natural gas. The product materials mainly include Gr B,X42, X52, X60, X65, and X70. Customers can choose their own products according to their own needs. Please refer to the table below for specific chemical composition and physical performance. In addition, the product specification level is divided into PSL1 and PSL2, which have different inspection requirements, chemical composition, and different mechanical properties. In total, PSL2 is higher than PSL1, so when ordering according to API5L standard, it is necessary to indicate in the contract that whether the specification level is PSL1 or PSL2 (API5L pipeline pipe).
The surface can be painted and marked, the two ends can be threaded and blunted, the two ends of the steel pipe can be equipped with pipe caps and protective covers, and various export packaging methods can ensure the safe transportation of products. Our products sell well all over the world, and high-quality products are unanimously recognized by customers.

Features of Petroleum Steel Pipe
- High Strength: Petroleum steel pipes are constructed from high-strength materials to withstand the high pressure and stress associated with the transportation of petroleum products. Common materials used include carbon steel, stainless steel, and alloy steel.
- Corrosion Resistance: The pipes are designed to resist corrosion, as petroleum products can be corrosive in nature. Corrosion-resistant coatings or linings are often applied to the pipes to protect them from the corrosive effects of the transported fluids.
- Seamless Construction: Seamless petroleum steel pipes are preferred over welded pipes in many applications due to their superior strength and integrity. The absence of welding seams eliminates potential weak points and enhances the overall structural integrity of the pipe.
- Heat Resistance: Petroleum steel pipes are designed to withstand high temperatures encountered during the transportation of hot fluids, such as hot crude oil or steam. The materials used are selected for their ability to maintain their mechanical properties even at elevated temperatures.
- Pressure Resistance: Petroleum steel pipes are engineered to withstand high-pressure conditions. They are manufactured with thick walls and are designed to handle the internal pressure exerted by the fluids being transported.
- Size Range: Petroleum steel pipes are available in various sizes and diameters to accommodate different flow rates and volume requirements. They can range from small-diameter pipes used in local distribution networks to large-diameter pipes used in long-distance pipelines.
- Connection Options: Petroleum steel pipes can be produced with different end connections to facilitate easy installation and connection with other pipeline components, valves, or fittings. Common end connections include threaded ends, flanged ends, and welding ends.
- Compliance with Standards: Petroleum steel pipes are manufactured in accordance with industry standards and specifications to ensure their quality, reliability, and compatibility with existing infrastructure. Some commonly followed standards include API (American Petroleum Institute) standards and ASTM (American Society for Testing and Materials) specifications.
These features collectively ensure the safe and efficient transportation of petroleum products through pipelines, meeting the stringent requirements of the oil and gas industry. It is important to note that specific features may vary depending on the application, operating conditions, and regulatory requirements governing the particular pipeline system.
