12Cr1MoVG Pipe Bending involves shaping seamless alloy steel pipes into bends (e.g., 3D, 5D, 7D, or 180° U-bends) for high-pressure, high-temperature applications. 12Cr1MoVG, a low-alloy chromium-molybdenum steel, contains approximately 0.08–0.15% carbon, 0.9–1.2% chromium, 0.25–0.35% molybdenum, and vanadium, offering excellent high-temperature strength (up to 580°C), creep resistance, and corrosion resistance. Compliant with GB5310 standards, these bends are ideal for boiler pipeline protection in power generation, petrochemical, and chemical processing industries.

Manufactured through hot induction bending or cold drawing with heat treatment (normalized and tempered), 12Cr1MoVG pipe bends are available in sizes from 6mm to 219mm (outer diameter) with wall thicknesses from 0.6mm to 22mm, and bend radii of 3D, 5D, 7D, or custom. They exhibit tensile strength (≥470 MPa), yield strength (≥255 MPa), elongation (≥21%), and hardness (≤190 HB), ensuring durability in demanding environments.

12Cr1MoVG pipe bends support welding, though thick-walled pipes (≥16mm) require preheating and post-weld heat treatment to prevent cracking. Rigorous testing, including chemical analysis, tensile testing, flattening tests (no cracks at H=0.7D), and nondestructive methods (radiographic, ultrasonic), ensures quality. The chromium and vanadium content forms a protective oxide layer, enhancing corrosion resistance, while coatings like FBE or passivation further protect against rust and chemical exposure.

With a density of approximately 7.85 g/cm³ and thermal conductivity of ~45 W/(m·K) at 20°C, 12Cr1MoVG pipe bends are lightweight yet robust, ideal for high-pressure boilers (pressure ≥9.8 MPa, temperature 450°C–580°C), superheaters, reheaters, and heat exchangers. Their smooth interior surfaces reduce flow resistance, making them suitable for boiler pipeline protection, refinery piping, cooling coils, and structural applications like handrails and frames.

For engineers seeking reliable high-temperature piping solutions, 12Cr1MoVG pipe bends offer exceptional strength, erosion resistance, and longevity, addressing challenges like pipeline corrosion and thermal stress in industrial settings.
