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 42crmo4+qt alloy steel plate equivalent, 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.
Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of 42crmo4+qt alloy steel plate equivalent, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
Our quality and service commitment: 42crmo4+qt alloy steel plate equivalent product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
