Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 1000 psi (dependent on nozzle size, material, and vessel design) |
| flow rate: | Varies by nozzle diameter and fluid properties (typically 0.5-50 m/s velocity range) |
| temperature: | -50°C to +400°C (dependent on material and gasket selection) |
| slurry concentration: | Up to 60% solids by weight (requires erosion-resistant materials and proper geometry) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Shell nozzles are used to provide openings in pressure vessel shells for connecting piping, installing instruments like pressure gauges or thermowells, or providing access points such as manways. They allow controlled fluid flow and monitoring while maintaining the vessel's structural integrity.
Common materials include carbon steel, stainless steel, and alloy steel. Specific grades such as Q235B, 304, or 316L may be used depending on the application. The choice depends on factors like corrosion resistance, temperature, and pressure requirements.
Relevant standards include ISO 6708 for nominal diameters, ASME B36.10 for wall thickness, ASME BPVC for design temperature, ISO 2768 for tolerances, and ISO 1302 for surface roughness. Always verify compliance with the manufacturer.
Selection involves determining the required nominal diameter, wall thickness, length, material grade, and pressure/temperature ratings based on your process. Consider the fluid type, operating conditions, and piping loads. Consult the manufacturer for model-specific data and verification.
