Inconel Ball Valve

At Falcon Valves & Flanges Pvt. Ltd., we design, manufacture, and supply high-integrity Inconel Ball Valves for extreme environments where standard stainless steels suffer from mechanical creep, thermal oxidation, or severe stress corrosion cracking (SCC).

Inconel (Nickel-Chromium-Iron superalloy) is the material of choice for high-temperature, high-pressure, and severely corrosive applications.

Falcon Inconel ball valves are designed to satisfy stringent international piping codes for complete pressure containment and absolute operational safety.

• Core Design Standards: API 6D (Pipeline Valves), ASME B16.34 (Pressure-Temperature Ratings), and ISO 17292 / BS 5351 (Metal Ball Valves).

• Wall Thickness & Dimensions: Thick-walled construction strictly compliant with ASME B16.34 to handle extreme pressure cycles.

• Face-to-Face Standards: ASME B16.10 or EN 558 to ensure standard drop-in replacement in industrial pipelines.

• End Connections: Available in Flanged (ASME B16.5 up to $24\text{"}$), Butt-Weld (ASME B16.25), Socket-Weld (ASME B16.11), and NPT Threaded ends.

• Top Flange Configuration: Built with an integrated ISO 5211 mounting pad for immediate, rigid bracketless automation (pneumatic/electric actuators).

The manufacturing process at Falcon relies heavily on chemical purity and controlled grain refinement to prevent common superalloy failure modes like "hot shortness" or micro-cracking during welding.

• Wrought/Forged Line (ASTM B564 / ASME SB564):

  • Inconel 600 (UNS N06600): Designed for high temperature oxidation resistance and resistance to chloride-ion stress corrosion cracking.

  • Inconel 625 (UNS N06625): High addition of Molybdenum and Niobium providing superior strength and pitting resistance.

  • Inconel 718 (UNS N07718): Precipitation-hardened grade providing extreme yield strength at temperatures up to $700^\circ\text{C}$.

• Cast Line (ASTM A494 / ASME SA494):

  • Grade CY40 (Inconel 600 Equivalent): Excellent for foundry pouring of complex flanged bodies.

  • Grade CW6MC (Inconel 625 Equivalent): High corrosion-erosion resistance for large-scale severe service valves.

1. Forging/Casting: Hot bar stock refinement or precise mold pouring to eliminate internal porosity.

2. Solution Annealing: Heat treatment to stabilize the chrome-carbides and optimize grain structure.

3. Precision Machining: CNC machining of the body, followed by mirror-polishing the internal Inconel ball to an ultra-smooth finish to reduce operating torque.

Every Falcon Inconel ball valve undergoes an intensive quality checklist before leaving our manufacturing floor.

• Positive Material Identification (PMI): 100% of body and trim components are verified via X-ray fluorescence (XRF) or optical emission spectrometry (OES) to guarantee exact Inconel chemistry.

• Radiographic Testing (RT) / Ultrasonic Testing (UT): Conducted on cast bodies (RT) and forged bar stocks (UT) to detect sub-surface defects or shrinkage cavities.

• Dye Penetrant Testing (DP): Applied to all weld overlays, stellite seats, and critical machined joints to ensure zero surface cracks.

All Falcon shipments come complete with a digital and physical engineering turn-over package:

• EN 10204 Type 3.1 Certified Material Test Reports (MTR) confirming mechanical properties and heat traceability.

• Pressure Testing Certificates (API 598).

• NACE Compliance Certificates.

• Detailed Operation & Maintenance (O&M) manuals.
