Critical Valve Requirements

H₂S service - NACE MR0175 / ISO 15156 mandatory for all wetted metallic components; HRC ≤ 22 Rockwell hardness limit on body, trim, and fasteners
Silica scaling - full-bore valves only; no throttle positions; pipeline injection of scale inhibitor upstream of brine valves
Two-phase flow (steam + liquid brine) - metal-to-metal seat or reinforced PTFE; no soft-seat-only designs in wellhead service
IBR certification for steam turbine supply headers in India - Form III-C material and Form III-E hydraulic test certificates mandatory
Chloride stress corrosion - Duplex 2205 or SS316L (not SS304); super duplex 2507 for high-chloride (>5,000 ppm Cl⁻) fields
Geothermal flash steam often contains non-condensable gases (NCG: H₂S, CO₂, NH₃) - valve materials must resist corrosion in this mixture

What certifications are required for geothermal power plants valves in Talcher?
For geothermal power plants in Talcher, the applicable standards are: NACE MR0175 / ISO 15156, ASME B16.34, IBR 1950 (Steam India), API 600, API 6D, API 598, ISO 9001:2015.

Third-party inspection (TPI) by EIL, Bureau Veritas, Lloyd's Register, or the client's nominated inspector can be arranged.
What is the delivery time for geothermal power plants valves to Talcher?
Standard stock sizes: delivery to Talcher in 3–7 business days. Custom sizes and special materials (Duplex, Hastelloy, P91): 4–8 weeks manufacturing lead time. Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What material is recommended for geothermal brine with high H₂S?
For geothermal brine containing H₂S above 0.0003 MPa partial pressure (the NACE MR0175 threshold), specify Duplex 2205 (ASTM A890 Grade 1B) with hardness confirmed ≤ HRC 22 as per NACE MR0175 / ISO 15156. Duplex 2205 provides both corrosion resistance (PREN ≥ 35) and the required hardness limit. For very high H₂S fields (> 1,000 ppm) or combined high chloride + H₂S, upgrade to Super Duplex 2507 (PREN ≥ 40). Carbon steel with SS316 trim is acceptable only for H₂S below the NACE threshold.
How does silica scaling affect valve selection for geothermal brine?
Silica (SiO₂) dissolved in geothermal brine precipitates when the brine cools below the silica saturation temperature (typically 80–120°C for high-silica fields). This scale deposits on valve seats, stems, and body ports, causing seizure and leakage. Mitigation: (1) use full-bore valves - no narrow ports where scale can bridge; (2) use ball valves in the full-open position only - do not use ball valves for throttling in scaling brine (scale deposits in the partially open cavity); (3) inject scale inhibitor upstream. Knife gate valves for slurry-heavy brine cut through scale deposits better than wedge gate.
