Corrosion-Resistant Valves for Petrochemical Processing
From ethylene crackers and acid alkylation units to polymer reactors and chemical distillation columns — GLB delivers exotic-alloy valves engineered for the petrochemical industry's most corrosive and high-temperature environments.
Engineered for Every Petrochemical Process
Purpose-built valve solutions for the full range of petrochemical applications — from high-temperature cracking to corrosive chemical processing and polymer production.
Ethylene Plants & Cracking Units
High-temperature isolation and control valves for steam crackers, quench towers, and fractionation columns. Designed for thermal cycling, coking resistance, and extended service intervals in ethylene production environments up to +650°C.
Chemical Processing & Reactors
Process isolation and throttling valves for chemical reactors, distillation columns, acid alkylation units, and heat exchangers handling corrosive media including sulphuric acid, hydrofluoric acid, and caustic soda.
Polymer Production
Reliable isolation and diverter valves for polymerisation reactors, pelletising systems, and monomer recovery loops. Engineered for high-viscosity polymer slurries, abrasive catalyst streams, and clean-in-place (CIP) requirements.
Overcoming Petrochemical Challenges
Petrochemical environments present uniquely aggressive conditions — corrosive acids, extreme temperatures, exotic material requirements, and strict emission regulations. Our valves are engineered to address each one.
Corrosion Resistance for Aggressive Media
Petrochemical streams frequently contain concentrated acids (H₂SO₄, HF, HCl), caustic solutions, and chloride-rich environments. Our valves are available in Alloy 20, Hastelloy C-276, and Duplex 2205 to resist pitting, crevice corrosion, and intergranular attack.
High-Temperature Cracking & Thermal Cycling
Cracking furnaces and reformer units operate at sustained temperatures exceeding +550°C with frequent thermal cycles. Inconel 625 and Alloy 800H trims maintain seal integrity and structural strength across extreme temperature ranges.
Exotic Alloy Material Expertise
We stock and machine exotic alloys including Alloy 20, Hastelloy C-276, Inconel 625, Duplex 2205, and Super Duplex 2507. Full positive material identification (PMI) and mill certificate traceability on every order.
Fugitive Emission & Environmental Control
ISO 15848-1 tested low-emission packing and stem seals minimise volatile organic compound (VOC) leakage to meet EPA Method 21 and TA-Luft requirements, helping petrochemical facilities maintain regulatory compliance.
Relevant Certifications
Every valve supplied to the petrochemical sector meets the applicable industry standards and certification requirements for corrosive and high-temperature service.
