Product Detail

The ASTM A105N Trunnion Ball Valve with UNS N06625 Weld Overlay and TCC Coating is a premium engineered solution for high-pressure, highly corrosive, and abrasive services. By utilizing an A105N (normalized carbon steel) forged body as the structural base and cladding all wetted parts with Inconel 625 (UNS N06625), this valve offers the chemical resistance of a solid alloy valve at a more cost-effective price point. To combat erosion, the ball and seats are hard-faced with Tungsten Carbide Coating (TCC), ensuring a robust metal-to-metal seal that excels in sour gas (NACE) and slurry applications.

Design Description

Corrosion-Resistant Overlay (CRA): The UNS N06625 weld overlay (typically 3mm thick) provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride and H₂S environments.
TCC Hard-Facing for Wear Resistance: The Tungsten Carbide Coating (TCC) on the ball and seats offers a surface hardness exceeding 60 HRC, protecting the sealing faces from high-velocity particles and sand.
Normalized A105N Forging: The normalized heat treatment of the A105N body ensures superior impact toughness and structural stability in high-pressure cycles.
Metal-to-Metal Sealing: Engineered for absolute reliability where soft seals would fail, achieving Bi-directional Class VI or better leakage rates.
NACE Compliance: Fully compliant with NACE MR0175/ISO 15156 for sour service in oil and gas production.
