Valves for Chlor-Alkali Plants - Bintulu
Bintulu in Sarawak is the operating base for Malaysia LNG (MLNG) - the world's largest LNG complex concentrated at a single location, with three trains (MLNG Satu, Dua, Tiga) plus PETRONAS LNG 9 collectively producing 24.7 million tonnes per year of LNG, making Malaysia the world's second-largest LNG exporter; MLNG valve requirements are among the most demanding in Southeast Asia - cryogenic A352 LCC and SS 316 gate and ball valves with BS 6364 extended bonnets for LNG service at -162 degrees C, API 6D full-bore pipeline ball valves for LNG loading arms and send-out pipelines, NACE MR0175 valves for sour gas feed processing, fire-safe API 607 valves for all hydrocarbon service, and Class 300-900 ASME B16.34 gate and globe valves for gas processing, NGL fractionation, and utilities; PETRONAS Chemicals Group (PCG) operates the Bintulu methanol and ammonia complex requiring globe valves and gate valves for synthesis gas processing; Press Metal Aluminium (Bintulu smelter - fed by 450 MW of Bakun hydro power) requires butterfly valves for cooling water, bath treatment systems, and anode baking furnace gas circuits; Bintulu Port handles 25 million tonnes/year including LNG, coal, palm oil, general cargo, and containers - requiring butterfly valves and gate valves for port utility systems; Vajra Industrial Solutions supplies Bintulu EPC contractors and MLNG shutdown teams with cryogenic valve packages, API 6D pipeline valves, and ASME B16.34 process valves with full PETRONAS and MLNG specification compliance.
PVDF-lined butterfly valves for wet chlorine gas, Hastelloy C-276 and titanium ball valves for hydrochloric acid, and SS316L diaphragm valves for caustic soda (NaOH) service.
Chlor-Alkali Plants Valves - Available in Bintulu
PVDF-Lined Butterfly Valve
PN 10 / PN 16Wet chlorine gas isolation - PVDF lining (or solid PVDF body) is uniquely resistant to wet Cl₂; titanium disc for highest corrosion resistance
Hastelloy C-276 Ball Valve
Class 150 / 300Hydrochloric acid (all concentrations, up to 100°C) - only Hastelloy C-276 and titanium resist HCl above 10% concentration
SS316L Diaphragm Valve
PN 10 / PN 16Caustic soda (NaOH 30–50%) process and transfer - SS316L body with EPDM diaphragm; also used for sodium hypochlorite
Titanium Ball Valve
Class 150 / 300Brine service and wet chlorine - Grade 2 titanium resists both Cl₂ and HCl; used in electrolysis cell connections
