A798/A798M-13 is a standard specification for steel pipes, plain-end or threaded-end, used for underground installation of thermoplastic-lined steel pipes and fittings.
The chemical composition of A798/A798M-13 steel grade includes elements such as carbon, manganese, phosphorus, sulfur, copper, and nickel. The carbon content is limited to a maximum of 0.30%, while the manganese content ranges from 0.30% to 1.20%. Phosphorus and sulfur are restricted to a maximum of 0.045%. Copper and nickel are present in small quantities to enhance corrosion resistance.
The key properties of A798/A798M-13 steel grade include high strength, good ductility, and excellent corrosion resistance. It is specifically designed for underground applications where resistance to corrosion and durability are essential.
This steel grade is commonly used in the oil and gas industry for pipelines, underground transportation of volatile chemicals, and water distribution systems. Its corrosion resistance and high strength properties make it suitable for harsh underground environments.
In summary, A798/A798M-13 steel grade has a well-defined chemical composition with controlled amounts of carbon, manganese, phosphorus, sulfur, copper, and nickel. Its key properties include high strength, good ductility, and excellent corrosion resistance, making it ideal for underground applications in the oil, gas, and water industries.
