Valves for Marine & Offshore Service - Map Ta Phut

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.

Trunnion ball valves, butterfly valves and gate valves in Super Duplex (F53) and Duplex (F51) for FPSO, offshore topsides, subsea wellheads, and marine seawater service.

We offer export documentation and delivery to Map Ta Phut in 7–14 business days with full documentation and third-party inspection.
What certifications are required for marine & offshore service valves in Map Ta Phut?
For marine & offshore service in Map Ta Phut, the applicable standards are: API 6D, NORSOK M-710 (Elastomer qualification), DNV-OS-D101 (Marine systems), Lloyd's Register, NACE MR0175 / ISO 15156, API 607 (Fire test), ASME B16.34, ISO 14313. 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.
What is the delivery time for marine & offshore service valves to Map Ta Phut?
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.
Why is standard SS 316 not suitable for offshore seawater service?
Stainless steel SS 316 (UNS S31600) has a PREN (Pitting Resistance Equivalent Number) of approximately 25, which is insufficient to resist pitting and crevice corrosion in seawater (chloride concentrations 18,000–35,000 ppm). Localised pitting can initiate within weeks in warm seawater. Duplex stainless (UNS S31803, PREN ~35) and Super Duplex (UNS S32750, PREN ~42) provide the corrosion resistance needed for continuous seawater service. For subsea and injection applications, Super Duplex is typically specified.
What is NORSOK M-710 and why does it matter for offshore valves?
NORSOK M-710 is a Norwegian offshore standard specifying qualification testing for non-metallic sealing materials (elastomers and thermoplastics) used in valves and other equipment on offshore installations, particularly on the Norwegian Continental Shelf. It tests resistance to high-pressure gas decompression, chemical resistance to hydrocarbons, and sour gas exposure. NORSOK M-710 qualification is required by most operators on the Norwegian Continental Shelf and is increasingly specified globally for FPSO and offshore topsides applications.
