Critical Valve Requirements

Chemical compatibility verification for every service - pH, temperature, concentration, and mixed chemical effects
Fugitive emission control: ISO 15848-1 Class A/B for benzene, chlorinated solvents, and toxic chemical services
PTFE-lined or solid alloy construction for halide (Cl, Br, F) acid service - SS 316 is inadequate for concentrated HCl
NACE MR0103 for refinery-adjacent chemical plants with H₂S exposure (stricter hardness limits than MR0175)
IBR certification for steam-traced piping and reactor steam-heated jackets
Antistatic design and ATEX actuators for flammable solvent services
PMI (Positive Material Identification) - critical for Hastelloy and high-alloy valve components

What certifications are required for chemical & petrochemical processing valves in Sur?
For chemical & petrochemical processing in Sur, the applicable standards are: API 6D, ASME B16.34, NACE MR0103 (Refinery chemicals), EN 593 (Butterfly valves), ISO 15848-1 (Fugitive emissions), ATEX (Explosive atmosphere equipment), IBR (Steam service). 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 chemical & petrochemical processing valves to Sur?
Standard stock sizes: export documentation and delivery to Sur 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.
What valve material is best for hydrochloric acid (HCl) service?
Hydrochloric acid attacks nearly all common metals including carbon steel, cast iron, and SS 316 at all concentrations. The main options are: Hastelloy C-276 (UNS N10276, ASTM A494 CW6MC in cast form) - the most widely used solid alloy for HCl valve bodies and trim at all concentrations up to ~65°C; PTFE-lined carbon steel or ductile iron ball valves and butterfly valves - cost-effective for lower pressures (PN 10/16) and moderate temperatures; Titanium (Grade 2) - resists HCl at low concentrations. Avoid SS 316, SS 304, and bronze for any HCl service.
What is the difference between NACE MR0103 and NACE MR0175 for chemical plant valves?
Both standards address sour service (H₂S-containing environments) but apply to different industries. NACE MR0175 (ISO 15156) applies to oil and gas field equipment (upstream and midstream) and focuses on naturally occurring H₂S in produced fluids. NACE MR0103 applies to downstream oil refinery and chemical plant equipment and is generally stricter - it sets lower maximum hardness limits for carbon steel components (Rockwell B 90 vs B 92 for MR0175) and includes additional requirements for weld hardness. If a chemical plant valve is used on a stream with H₂S, specify the applicable standard in the purchase order.
