Common Standards
Standards are checked against the drawing, project specification and requested inspection route.
- Project drawing or purchase specification
- ASME B16.5 where flange dimensions follow ASME classes
- EN 1092-1 / DIN where PN and DN requirements are specified
- GOST 33259, 12820 or 12821 where CIS project requirements apply
- ASTM, EN or project material standards as listed in the RFQ
Material Grades
Material review confirms grade, service condition, heat treatment and certificate expectations before quotation.
ASTM A105 carbon steel
ASTM A350 LF2 low-temperature carbon steel
Stainless steel grades such as 304, 316, 321 or 347
Duplex and super duplex grades when specified by the project
Alloy steel or drawing-specified grades subject to feasibility review
Size, Pressure, Class and Drawing Review Points
These items help prevent missing technical details during the first quotation review.
Size, DN or NPS
Pressure class or PN rating
Drawing revision and critical dimensions
Facing, bore, bolt pattern and machining tolerance
Quantity, destination country and packing requirement
Manufacturing Route
The practical route is reviewed before price and lead time are confirmed.
- Material review
- Forging route confirmation
- Heat treatment
- Rough machining
- Final machining
- Inspection and document review
- Marking, packing and export document preparation
Inspection and Documents
Inspection requirements should be included with the RFQ so document cost and timing are clear early.
MTC EN 10204 3.1
Heat treatment record
Dimensional report
PMI when alloy verification is required
UT, MT or PT when specified
Tensile, impact or hardness test records when required
Third-party inspection support by project request

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 Nipoflanges 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 Nipoflanges?
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.
