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 100 bar (design dependent) |
| flow rate: | Varies with diameter (typically 0.5-10 m/s superficial velocity) |
| temperature: | -50°C to 400°C (dependent on material of construction) |
| slurry concentration: | Up to 40% solids by weight (with proper internals design) |
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.
Common materials include carbon steel, stainless steel, alloy steel, and fiberglass reinforced plastic. The choice depends on the process media, temperature, pressure, and corrosion requirements. Specific grades such as Q345R, 304, and 316L are listed as reference examples.
The column shell is typically designed and verified according to Chinese standards such as GB/T 150 for pressure vessels, GB/T 9019 for nominal diameter, and GB 50009 for wind load. Other standards like GB/T 713, GB/T 3280, GB/T 1804, and GB/T 1031 may apply to materials, tolerances, and surface finish.
Wall thickness is determined based on the design pressure, temperature, and material strength, following the rules of the applicable pressure vessel code (e.g., GB/T 150). The reference range is 6–60 mm, with thicker walls required for higher pressures.
Hydrostatic leak tests are performed at pressures of 1.1–1.5 MPa, as per the design code. Additionally, dimensional checks, material verification, and non-destructive testing may be required. Always confirm the specific test requirements with the manufacturer or supplier.
