ASTM A691 GR 1.25 CR

ASTM A691 GR 1.25 CR pipes are available in sizes ranging from 1/2 inch to 36 inches in nominal bore (NB) with wall thicknesses up to 75 mm. These pipes cater to diverse project requirements with customizable options such as plain, beveled, or threaded ends, as well as surface finishes like black painting, galvanized, and anti-corrosion coatings. Manufactured to stringent ASTM specifications, these pipes undergo rigorous heat treatments, including normalizing and tempering, to achieve optimal mechanical stability. With a tensile strength range of 450 to 585 MPa and a yield strength of 275 MPa minimum, these pipes ensure reliability under extreme conditions.

The material composition of ASTM A691 GR 1.25 CR pipes includes 1.25% chromium and 0.5% molybdenum, which enhance their resistance to oxidation and thermal stress. They also contain a balanced mix of carbon, manganese, phosphorus, sulfur, and silicon, providing excellent weldability and toughness. These features make them ideal for applications in oil refineries, chemical plants, and shipbuilding, where high-strength, corrosion-resistant materials are critical.

Dimensional tolerances for ASTM A691 GR 1.25 CR pipes are precisely maintained, with an outside diameter variation of ±1% and a wall thickness tolerance of +12.5%/-10%. This ensures compatibility with international standards and seamless integration into various industrial systems. Additionally, these pipes are available in multiple schedules, including SCH 40, SCH 80, SCH 120, and SCH XXS, providing versatility for diverse operational demands. Custom lengths of up to 12 meters are also offered to meet specific project requirements.
