Question 1

Do you supply desalination & high-purity water valves in Richards Bay?

Accepted Answer

Yes. Vajra Industrial Solutions supplies Butterfly Valve (Duplex / Super Duplex), High-Pressure Ball Valve (SWRO Membrane Train), Check Valve (Pump Discharge, Duplex), Diaphragm Valve (Chemical Dosing & Permeate) for desalination & high-purity water applications in Richards Bay, KwaZulu-Natal. Richards Bay on South Africa's KwaZulu-Natal coast is a major heavy-industry and export hub, home to Rio Tinto's Richards Bay Minerals titanium and zircon operation, South32's Hillside aluminium smelter, the Foskor phosphoric-acid and fertilizer complex, and the Richards Bay Coal Terminal - one of the world's largest coal export facilities; mineral processing, smelting, and acid service demand highly corrosion- and abrasion-resistant valves - PTFE- and PFA-lined ball and butterfly valves and Alloy 20 / Hastelloy valves for phosphoric and sulphuric acid duty, knife gate and pinch valves for slurry, ore, and coal handling, high-temperature gate and globe valves for smelter and power service, API 6D ball and gate valves in A216 WCB and A351 CF8M for utility and fuel lines, and API 526 safety-relief valves; SANS/SABS conformity, ASME B16.5 flanges, and full material certification are required; Vajra Industrial Solutions supplies Richards Bay smelter, mineral-processing, fertilizer, and port buyers with lined, alloy, abrasion-resistant, and API 6D valve packages with full traceability and export documentation to South Africa. We offer export documentation and delivery to Richards Bay in 7–14 business days with full documentation and third-party inspection.

Question 2

What certifications are required for desalination & high-purity water valves in Richards Bay?

Accepted Answer

For desalination & high-purity water in Richards Bay, the applicable standards are: ASME B16.34, ISO 9001:2015, AWWA C504 (Butterfly valves for water), AWWA C516 (Large diameter rubber-seated butterfly valves), NSF 61 / NSF 372 (Drinking water materials), EN 593 (Butterfly valves), NACE MR0175 (Sour service - for associated oil & gas desal). 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 desalination & high-purity water valves to Richards Bay?

Accepted Answer

Standard stock sizes: export documentation and delivery to Richards Bay 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 valve materials are required for seawater reverse osmosis (SWRO) plants?

Accepted Answer

SWRO plants require careful material selection due to seawater's high chloride content (28,000–38,000 ppm Cl⁻ in typical seawater). For seawater-wetted components: Duplex stainless UNS S31803 (PREN ~35) is the standard minimum for body, disc, and trim; Super Duplex UNS S32750 (PREN ~42) is preferred for warm seawater (above 30°C) and brine concentrate. SS 316 (PREN ~25) is insufficient for long-term seawater service and will develop pitting corrosion. On the permeate side (pure water): SS 316L is suitable, or PVDF/CPVC thermoplastics for aggressive pure water service.

Question 5

What pressure class is required for SWRO membrane train valves?

Accepted Answer

SWRO (Seawater Reverse Osmosis) systems typically operate at 55–80 bar feed pressure (depending on seawater salinity and temperature). This corresponds to ASME Class 300 (approximately 51 bar at ambient temperature in SS 316) to Class 600 (approximately 103 bar). Most SWRO designers specify Class 600 rated valves (in SS 316 or Duplex) for membrane train isolation to provide an adequate safety margin above the 80 bar maximum operating pressure. High-pressure booster pump stages may require Class 900 in some ultra-high recovery designs.
