What to specify in your RFQ
Manufacturers quote faster and more accurately when your request covers these points.
- Size and connection type
Specify pipe nominal diameter, face-to-face length, and flange or spool connection (flanged, welding ends, lap joint) so the manufacturer can match the joint geometry.
- Elastomer/material compound
Name the rubber compound (EPDM, NBR/Nitrile, Neoprene, Viton/FKM, etc.) and any lining materials required for chemical compatibility.
- Pressure and temperature ratings
Give maximum operating pressure, test/allowable pressure, and continuous and peak temperature ranges so the supplier can select arch/profile and reinforcement.
- Movement requirements
List axial, lateral, and angular movement amounts plus expected cycles to determine arch count, reinforcement, and life expectancy.
- End-use industry and fluids
State the application (HVAC, power, oil & gas, water/wastewater, chemical) and the conveyed fluid to confirm material and certification needs.
- Standards and certifications
Request compliance or testing to relevant standards (EJMA, API, ASTM) and any customer-required certifications.
- Quantity and lead time
Provide required quantity, single-order and annual volumes, and target delivery date to allow lead-time and MOQ assessment.
