Question 1

Do you supply nuclear power plants valves in Tianjin?

Accepted Answer

Yes. Vajra Industrial Solutions supplies Gate Valve (ASME Sec. III Cl.2), Globe Valve, Check Valve, Butterfly Valve for nuclear power plants applications in Tianjin, Tianjin Municipality. Tianjin's Binhai New Area is one of China's largest petrochemical and chemical clusters — anchored by Sinopec Tianjin Petrochemical (10 Mtpa refinery and 1 Mtpa ethylene cracker) and CNPC's Dagang Oilfield complex producing crude and natural gas from the Bohai Bay; TEDA Economic Zone hosts dozens of downstream chemical manufacturers requiring corrosion-resistant SS 316 and Hastelloy process valves; Vajra Industrial Solutions supplies API 608 floating ball valves, ASME B16.34 Class 300–600 gate valves, and PTFE-seated butterfly valves for Tianjin-based petrochemical plants and EPC contractors, with CE/PED and full ISO documentation for Chinese customs clearance. We offer export documentation and delivery to Tianjin in 7–14 business days with full documentation and third-party inspection.

Question 2

What certifications are required for nuclear power plants valves in Tianjin?

Accepted Answer

For nuclear power plants in Tianjin, the applicable standards are: ASME Section III (Class 2/3), ASME B16.34, IEEE 382 (MOV), IEEE 344 (Seismic), 10 CFR 50 Appendix B, AERB (India), NRC Regulatory Guides. All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports. Third-party inspection (TPI) by EIL, Bureau Veritas, Lloyd's Register, or the client's nominated inspector can be arranged.

Question 3

What is the delivery time for nuclear power plants valves to Tianjin?

Accepted Answer

Standard stock sizes: export documentation and delivery to Tianjin in 7–14 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.

Question 4

What is ASME Section III and why does nuclear require it?

Accepted Answer

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.

Question 5

What is the difference between nuclear Class 2 and Class 3 valves?

Accepted Answer

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.
