Valves for Nuclear Power Plants - Mettur

Mettur in Tamil Nadu is a major chlor-alkali and chemical centre anchored by Chemplast Sanmar's PVC and caustic-soda complex - one of South India's largest producers of PVC resin, caustic soda, chlorine, and hydrochloric acid, alongside the MALCO (Madras Aluminium, Vedanta) site, the Mettur Thermal Power Station (TANGEDCO, 840 MW), and the Mettur Dam hydroelectric plant; the highly corrosive chlor-alkali and chlorine-derivative processes drive strong demand for PTFE-lined and PFA-lined ball, diaphragm, and butterfly valves, titanium and Hastelloy C-276 valves for wet-chlorine and hypochlorite service, and rubber-lined valves for brine and effluent handling; the thermal power station requires ASME B16.34 Class 600-900 gate and globe valves and high-temperature alloy-steel valves under IBR certification for steam and feedwater service; cooling-water systems use butterfly valves; procurement follows IBR (steam), ASME, API, and IS standards with EN 10204 3.1 MTCs and strict material traceability for chlorine service; Vajra Industrial Solutions supplies Mettur and Salem-belt chemical, aluminium, and power buyers with lined, corrosion-resistant, and IBR-certified valve packages with fast delivery across Tamil Nadu.

What is ASME Section III and why does nuclear require it?
ASME Section III is the Boiler and Pressure Vessel Code for Nuclear Facility Components. Unlike ASME B16.34 (industrial valves), Section III imposes full design analysis, material traceability to mill certificates (CMTRs), N-stamp third-party oversight during manufacturing, and complete quality records. Class 1 covers the primary pressure boundary (reactor coolant), Class 2 covers safety-related secondary systems (ECCS, spent fuel cooling), and Class 3 covers other safety-related systems (service water). Vajra supplies Class 2 and 3 components for balance-of-plant applications.
What is the difference between nuclear Class 2 and Class 3 valves?
ASME Section III Class 2 applies to systems that could affect the safety function of the reactor coolant boundary - e.g., emergency core cooling, spent fuel pool cooling. Class 3 applies to systems important to safety but with a lower direct interface - service water, fire protection, component cooling water. Class 2 requires more rigorous design documentation, full material traceability, and N-stamp inspection. Class 3 has slightly relaxed requirements but still demands CMTRs and a documented QA programme.
