Use this guide to prepare a clearer technical request. Final manufacturing feasibility is confirmed against the complete RFQ, drawings and project specification.
Use a complete specification
A dimensional-standard reference does not replace fitting type, material grade, size, schedule, quantity or project conditions.
Define fitting geometry
For elbows state angle and radius; for tees identify run and branch; for reducers identify end sizes and concentric or eccentric form.
Confirm wall and ends
State the mating pipe schedule, minimum-wall requirement, bevel and any field-welding constraints.
Control the edition
Identify the required standard edition and any purchaser specification that changes dimensions, tolerances, marking or testing.
Agree inspection
Define dimensional records, material documents, surface acceptance and packing checks before manufacture.
Standards can be revised and projects may add special requirements. State the designation, edition and supplementary conditions in the RFQ.
