FAQ:
Q1: Can this adapter handle hydrofluoric acid (HF)?
A: Standard 316L offers limited HF resistance. For concentrated HF service, inquire about Alloy C276 options.
Q2: Is thread sealant required for NPT connection?
A: Metal-to-metal NPT taper seals effectively without sealant. For extra assurance, PTFE tape is compatible.
Q3: Are gaskets included with VCR connections?
A: VCR connections typically require separate metal gaskets (e.g., SS 316L). Specify if you need gasket kits.
Q4: What's the lead time for custom sizes?
A: Non-standard sizes (beyond 1/8"-1/2") have a 3-4 week production time. Expedited service is available.
Q5: How is surface passivation performed?
A: We use nitric acid passivation per ASTM A967 Method 5, with optional electropolishing for critical cleanability.
Q6: Can you provide material test certificates?
A: Yes, full MTRs (Mill Test Reports) with chemical analysis and mechanical properties are supplied upon request.
