Question 1

Do you supply desalination & high-purity water valves in Map Ta Phut?

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 Map Ta Phut, Rayong. Map Ta Phut Industrial Estate in Rayong is Thailand's largest petrochemical and heavy-industry hub and the centrepiece of the Eastern Economic Corridor (EEC), hosting PTT Global Chemical (PTTGC - Southeast Asia's leading integrated petrochemical producer), SCG Chemicals, IRPC, HMC Polymers, Vinythai, and dozens of olefins, aromatics, polyethylene, polypropylene, and PVC plants; the cluster generates sustained demand for API 6D ball valves, ASME B16.34 gate and globe valves, API 609 butterfly valves, and API 526 safety relief valves for steam crackers, fractionation columns, and polymer reactors, plus PTFE-lined and exotic-alloy valves (Hastelloy, Alloy 20) for the Vinythai chlor-alkali and PVC chains; the PTT Map Ta Phut LNG receiving terminal (11.5 MTPA) requires cryogenic A352 LCC valves for regasification; Thai industrial procurement follows TIS and international ASME/API standards with EN 10204 3.1 MTCs and increasingly stringent fugitive-emission requirements (ISO 15848) driven by Thailand's industrial air-quality regulations; Vajra Industrial Solutions supplies Map Ta Phut EPC contractors and turnaround teams with corrosion-resistant, fire-safe, and low-emission valve packages. We offer export documentation and delivery to Map Ta Phut 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 Map Ta Phut?

Accepted Answer

For desalination & high-purity water in Map Ta Phut, 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 Map Ta Phut?

Accepted Answer

Standard stock sizes: export documentation and delivery to Map Ta Phut 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.
