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.
The axial stroke typically ranges from 300 to 1000 mm, depending on the model and application. This stroke compensates for vessel heave and wave motion. Always verify the exact stroke for your specific joint with the manufacturer.
Common materials include AISI 316L stainless steel for corrosion resistance, with corrosion-resistant coatings. Seal materials are typically NBR or HNBR, suitable for marine environments. Confirm material grades with the supplier for your application.
Relevant standards include applicable standards for pressure testing and leakage rates, and API 6A for end connections. These standards serve as procurement references; verify compliance with the manufacturer.
Consider the required nominal diameter, operating pressure, axial stroke, temperature range, and end connection type. Ensure the joint meets the necessary standards and verify all specifications with the legal manufacturer or supplier.
