Detail Facts of API 5L X70 PSL 2 Carbon Steel Line Pipes

About API 5L X70 PSL 2 Carbon Steel Line Pipes

API 5L X70 PSL 2 is a high-strength carbon steel line pipe that is used for transporting oil, gas, and other fluids in pipelines. PSL stands for "product specification level," and PSL 2 indicates that the pipe is manufactured to a higher level of quality and performance than PSL 1.

Here are some key specifications and features of API 5L X70 PSL 2 carbon steel line pipes

• Material: API 5L X70 PSL 2 line pipes are made from carbon steel with a composition of manganese, phosphorus, sulfur, and silicon. The exact API 5L X70 Chemical Composition can vary depending on the production process and the manufacturer.
• Size range: The size range of API 5L X70 PSL 2 line pipes can vary depending on the manufacturer, but it typically ranges from 2 inches to 48 inches in outer diameter.
• Yield strength: The minimum yield strength of API 5L X70 PSL 2 line pipes is 70,300 psi, or 485 MPa.
• Tensile strength: The minimum tensile strength of API 5L X70 PSL 2 line pipes is 82,700 psi, or 570 MPa.
• Elongation: The minimum elongation of API 5L X70 PSL 2 line pipes is 22% for longitudinal and 20% for transverse specimens.
• Charpy V-notch impact testing: API 5L X70 PSL 2 line pipes must pass Charpy V-notch impact testing at a temperature of -20°C (-4°F) and with a minimum average energy of 27 J (20 ft-lbf).
• Hydrostatic testing: API 5L X70 PSL 2 line pipes must undergo hydrostatic testing to ensure that they meet the required pressure rating.
• Corrosion resistance: API 5L X70 PSL 2 line pipes have good corrosion resistance, which is important for pipelines that transport fluids that can be corrosive.

API 5L X70 PSL 2 line pipes are commonly used in the oil and gas industry for long-distance pipelines, offshore pipelines, and other applications that require high-strength and corrosion-resistant materials.

API 5L X70 Chemical Composition

Depending on the manufacturing method and the manufacturer, the API 5L X70 Chemical Composition line pipes might change, but the following is a typical composition: Carbon (C) is represented by 0.28%, Silicon (Si) by 0.45%, Manganese (Mn) by 1.35%, Phosphorus (P) by 0.030%, Sulfur (S) by 0.030%, Niobium (Nb) by 0.07%, Vanadium (V) by 0.06%, Titanium (Ti) by 0.04%, Aluminum (Al) by 0.06%, Copper (Cu) by 0.22%, Nickel (Ni) Compared to other carbon steel materials, the carbon content of API 5L X70 PSL 2 line pipes is relatively low, yet it is sufficient to give great strength and durability. The strength and toughness of the material are enhanced by the addition of additional alloying elements including silicon, manganese, niobium, vanadium, and titanium to the composition.

It is crucial to remember that the precise composition of API 5L X70 PSL 2 line pipes might change based on the production process and the unique requirements of the application. The manufacturer is required to submit a test report demonstrating conformity with the stated specifications, and the chemical composition is often mentioned in the purchase order.
