Question 1

Do you supply desalination & high-purity water valves in Ras Tanura?

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 Ras Tanura, Eastern Province. Ras Tanura hosts the Saudi Aramco Ras Tanura Refinery (around 550,000 bpd) and the Ras Tanura and Ju'aymah crude and NGL export terminals - among the largest oil-loading complexes in the world - alongside the associated petrochemical and gas-processing units in Aramco's Eastern Province heartland; valve demand is refinery, terminal, and export-critical - API 600 gate, API 623 globe, and API 526 safety-relief valves for crude and product process units, API 6D ball and gate valves for tank-farm, pipeline, and marine-loading manifolds, fire-safe API 607 and API 6FA valves for terminals and jetties, NACE MR0175 sour-service trims for H2S-rich Arabian crude and gas, and A995 duplex and 6-Moly valves for seawater cooling and ballast systems; Aramco procurement mandates compliance with Aramco engineering standards (SAES), fire-safe testing, and EN 10204 3.1 MTCs; Vajra Industrial Solutions supplies Ras Tanura refining, terminal, and petrochemical buyers with API-certified, fire-safe, and sour-service valve packages with full export documentation and fast delivery across the Gulf. We offer export documentation and delivery to Ras Tanura 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 Ras Tanura?

Accepted Answer

For desalination & high-purity water in Ras Tanura, 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 Ras Tanura?

Accepted Answer

Standard stock sizes: export documentation and delivery to Ras Tanura 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.
