Globe Valves for Refinery & Petrochemical Process
Full range of refinery and petrochemical process valves - ASME B16.34, API 6D, NACE sour service, high-temperature alloy steel - for IOCL, BPCL, HPCL, Reliance, and EPC projects.
Which globe valves are used for refinery & petrochemical process?
Oil refineries and petrochemical complexes require valves across the widest possible range of operating conditions - from low-pressure condensate to high-pressure hydrogen, from ambient temperature naphtha to 450°C hot oil, and from dry utility gas to H₂S-bearing sour streams. Compliance with ASME B16.34, API 6D, API 600, API 607, NACE MR0175, and IBR (for steam) is mandatory.
Globe Valve (Control & Isolation)
Throttling, flow control, and pressure regulation in refinery process and utility headers
Critical Requirements
- ASME B16.34 pressure-temperature rating compliance - mandatory for all pressure-containing valve components
- API 600 gate valve design standard (bolted bonnet, outside screw and yoke, backseat)
- IBR certification for steam lines: Form III-C (material) and Form III-E (test certificate)
- API 607 fire-safe certification for all valves handling flammable hydrocarbons
- NACE MR0175 / ISO 15156 for sour service (H₂S ≥50 ppm or sour conditions)
- Fugitive emission compliance: ISO 15848-1 Class B or better for VOC-containing services
Service Challenges
- Crude oil at elevated temperature (300–400°C) - alloy steel WC9 or C12A required
- H₂S and mercaptans - NACE MR0175 hardness-controlled materials
- Hydrogen service - hydrogen embrittlement risk; special material grades and testing required
- Hot naphthas and aromatics - PTFE seats degrade above 230°C; metal seats required
- Caustic (NaOH) - stress corrosion cracking risk in CS; SS 316 or nickel alloy required
- Amines (DEA, MDEA) - amine SCC in carbon steel welds; PWHT (post-weld heat treatment) required
