A672 GR D70

ASTM A672 GR D70 pipes typically have diameters starting at 16 inches, with wall thicknesses ranging up to 3 inches. The chemical composition includes 0.25% carbon, 0.98% manganese, 0.64% molybdenum, and 0.45% silicon, providing an optimal balance of strength and ductility. These pipes deliver a minimum yield strength of 37 MPa and a tensile strength of 65 MPa, making them suitable for high-pressure applications. They are often coated with anti-corrosion treatments such as black paint, varnish, or 3LPE coatings for enhanced durability in harsh environments.

The versatility of ASTM A672 GR D70 pipes makes them ideal for structural purposes and fluid, gas, and oil transmission in industries like petroleum refineries, power generation, and chemical processing plants. Their ability to withstand pressure variations and moderate temperatures ensures reliable performance in critical operations. These pipes are available in various surface treatments, including galvanized and epoxy-coated options, to meet diverse application requirements.

ASTM A672 GR D70 pipes comply with stringent standards such as ASME SA672 and ASTM A672, ensuring consistent quality and reliability. Heat treatments, including normalization and stress-relief processes, may be applied based on class requirements. Each pipe undergoes rigorous testing methods such as ultrasonic examinations, radiographic inspections, and Charpy V-Notch tests to meet industry standards for safety and performance.
