A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory reference, the design pressure range is 1.0–1.6 MPa, as per GB/T 150. Always confirm the exact design pressure for your specific application with the manufacturer.
The materials on file include carbon steel, stainless steel, and alloy steel. A specific material grade listed is Q345R (per GB/T 713) for general service. Material selection depends on the media, temperature, and pressure requirements.
The hydrostatic test pressure is 1.25–2.0 MPa, which is 1.25 times the design pressure, as per GB/T 150. This test ensures the vessel can withstand overpressure conditions. Verify the exact test pressure with the manufacturer.
The design temperature range is -40 to 150°C, as per GB/T 150. Material properties degrade above 150°C, so operation beyond this limit is not recommended without proper evaluation. Confirm the temperature rating for your specific model.
