Common Buyer Mistakes
These points often cause repeated clarification or delayed quotation.
- Sending a product name without standard, drawing or pressure rating
- Leaving bore, facing or bolt pattern unclear
- Mixing DN, NPS, PN and class references without a drawing
- Omitting inspection documents until after price discussion
- Forgetting destination country, packing or third-party inspection requirements
FAQ
Short answers for common RFQ questions.
Can you review Ring Flanges by drawing?
Yes. Send the latest drawing revision with material, quantity, tolerance, inspection and destination requirements so the RFQ can be checked before quotation.
What information is needed before quotation?
A practical RFQ should include standard or drawing, size, pressure rating, material grade, quantity, inspection requirements and destination country.
Which materials are common for Ring Flanges?
Common requests include ASTM A105, A350 LF2, stainless steel, duplex steel and project-specified alloy grades, subject to drawing and service requirements.
Can inspection documents be arranged?
MTC 3.1, dimensional reports, heat treatment records, PMI, UT, MT, PT and third-party inspection can be reviewed according to the project requirement.
