ASME B16.34 is the American Society of Mechanical Engineers’ standard titled:
“Valves – Flanged, Threaded, and Welding End”
It defines the design requirements for:
At Perfect Engineers, we incorporate ASME B16.34 guidelines into every stage of valve manufacturing, especially for high-pressure needle valves.
| Category | ASME B16.34 Requirement | Perfect Engineers Compliance |
|---|---|---|
| Design Pressure Rating | Must match pressure class for given temperature | Up to 10,000 PSI valves available |
| Wall Thickness | Minimum required based on material & pressure class | Calculated using B16.34 Annex B formulas |
| End Connection Types | Flanged, threaded (BSP/NPT), socket weld, butt weld | All supported as per valve rating |
| Marking | Material, pressure class, size, manufacturer’s ID | Laser/etched marking on all valves |
| Material Standards | ASTM-compliant materials required | SS316, SS304, Monel, Hastelloy, Alloy 20 etc. |
| Testing Requirements | Hydrostatic and seat leakage test as per API 598 or MSS-SP-61 | Full testing & certification provided |
| Industry | Why It’s Required |
|---|---|
| Oil & Gas | High-pressure, high-temperature pipeline safety |
| Power Generation | Steam systems and turbine instrument loops |
| Chemical Processing | Acid and solvent containment at varying temperatures |
| Pharmaceutical | Compliance with global safety standards |
| Marine & Offshore | Required for all mission-critical valve components |
