Question 1

Do you supply desalination & high-purity water valves in Le Havre?

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 Le Havre, Normandy. Le Havre in Normandy is a major French industrial and port centre anchored by the TotalEnergies Normandy refinery at Gonfreville-l'Orcher (around 247,000 bpd) and its integrated petrochemical platform, together with Chevron Oronite additives, Yara fertiliser, and the vast HAROPA Port of Le Havre - France's leading container port and a growing offshore-wind fabrication base; refinery, petrochemical, and chemical service demands PED 2014/68/EU-compliant valves with CE marking - API 6D and EN-standard ball, gate, and globe valves in A216 WCB and A351 CF8M, NACE valves for sour and hydrotreating service, high-temperature WC9 and F22 valves for reformer, hydrocracker, and FCC duty, fire-safe API 607 / ISO 10497 valves, PTFE- and PFA-lined valves for corrosive chemical and additive service, low-fugitive ISO 15848 / TA-Luft valves, and API 526 / EN ISO 4126 safety-relief valves; EN 1092-1 flanges, PED conformity, and EN 10204 3.1 MTCs are required; Vajra Industrial Solutions supplies Le Havre refinery, petrochemical, chemical, and offshore-wind buyers with PED/CE-compliant API 6D, NACE, fire-safe, lined, and low-fugitive valve packages with full export documentation and EUR.1 customs support. We offer export documentation and delivery to Le Havre 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 Le Havre?

Accepted Answer

For desalination & high-purity water in Le Havre, 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 Le Havre?

Accepted Answer

Standard stock sizes: export documentation and delivery to Le Havre 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.
