A672 GR K85

The ASTM A672 Grade K85 pipes are available in nominal sizes ranging from 1/2 inch to over 64 inches, with wall thicknesses of up to 250 mm to suit diverse project needs. These pipes undergo various heat treatments, such as normalization and stress relief, based on the specific class, ensuring enhanced mechanical stability and resilience. With minimum tensile strength of 485 MPa and yield strength of 260 MPa, these pipes exhibit excellent pressure resistance and structural integrity, making them suitable for critical operations in industries worldwide.

Chemical composition and mechanical properties are key highlights of Grade K85 pipes. The inclusion of chromium and manganese, combined with controlled carbon content (maximum 0.25%), ensures a balance between strength and weldability. These pipes undergo stringent quality tests such as radiographic examination, ultrasonic testing, and pressure testing, guaranteeing compliance with international standards. Moreover, they are engineered to withstand demanding environments, making them ideal for both structural and fluid transmission purposes.

The pipes are offered in standard lengths of 3m, 6m, and 12m, with options for customization up to 30m. Various end finishes, such as beveled, plain, or threaded ends, are available to meet client requirements. To prevent corrosion and damage during transport, the pipes are coated with protective layers like epoxy or 3LPE and packaged in wooden boxes or shrink wrapping. Additional tests for hardness, charpy impact, and pressure resistance are performed to ensure their performance under extreme conditions.
