Pipeline steel is a kind of steel specially used for transporting natural gas and petroleum with special requirements. Why do oil and gas pipelines use pipeline steel as the transportation pipeline? Because pipeline steel has the following characteristics. First, the pipeline steel is strong, and it is not easy to break. If it breaks during transportation, the consequences are unimaginable. Second, the , pipeline steel is durable. Pipeline steel is buried deep underground for a long time and has good corrosion resistance. Third, the pipeline steel is resistant to high temperature and will not deform under high temperature.
