Question 1

Do you supply coke oven & steel plants valves in Chengdu?

Accepted Answer

Yes. Vajra Industrial Solutions supplies Knife Gate Valve, Butterfly Valve (Large Bore), Gate Valve (IBR Steam), Globe Valve (Control) for coke oven & steel plants applications in Chengdu, Sichuan. Chengdu is the gateway to the Sichuan Basin — China's largest and most prolific natural gas producing region, operated by PetroChina Southwest Oil & Gas Field Company and CNOOC Sichuan; Sichuan's gas fields feed China's West-East Gas Pipeline system, requiring API 6D Class 600–1500 natural gas ball valves, fully welded body pipeline ball valves, and pneumatic actuated butterfly valves for compressor station and metering station service; Vajra Industrial Solutions supplies cryogenic-rated and gas-service ball valves for Sichuan Basin pipeline projects and Chengdu-area petrochemical and chemical plants, with complete API 6D, ASME B16.34, and CNPC Q/SY standard documentation. We offer export documentation and delivery to Chengdu in 7–14 business days with full documentation and third-party inspection.

Question 2

What certifications are required for coke oven & steel plants valves in Chengdu?

Accepted Answer

For coke oven & steel plants in Chengdu, the applicable standards are: IS 6157 (BFG Gate Valves), ASME B16.34, IBR 1950 (Steam), API 600, API 609, IS 2825, ASME B16.10. 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 coke oven & steel plants valves to Chengdu?

Accepted Answer

Standard stock sizes: export documentation and delivery to Chengdu 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

Why are knife gate valves preferred for blast furnace gas?

Accepted Answer

Conventional wedge gate valves trap BFG tar and dust in the body cavity, causing the gate to seize. Knife gate valves have no body cavity — the blade cuts through the medium with a shear action, shedding deposits on actuation. The flat-face gate also allows easy replacement in-situ when the knife edge wears, without removing the body from the pipeline. For large BFG mains (DN600–DN2400), double-offset butterfly valves are preferred over knife gates for better shutoff and lower actuator torque.

Question 5

What IBR documentation is required for steel plant steam valves?

Accepted Answer

All steam valves above 3.5 kg/cm² must carry IBR Form III-C (Certified Material Test Report from the steel mill, showing heat number, chemical analysis, and mechanical test results) and IBR Form III-E (Hydraulic Test Certificate from the valve manufacturer, showing test pressure = 1.5 × rated working pressure held for ≥ 30 minutes). Vajra supplies both certificates as part of the standard documentation package for all IBR-certified valves.
