F91 Dövme Flanşların PMI ve Ultrasonik Testleri Tamamlandı
Positive material identification and ultrasonic testing were completed for an ASTM A182 F91 forged flange package. The inspection plan used PMI to verify alloy identity and UT to examine internal quality, supported by hardness, dimensional and traceability reviews.

Delivery highlights
PMI verification for F91 material identity
PMI readings were taken at prepared locations under the approved procedure and compared with the project acceptance criteria. Instrument identification, calibration checks, operator, item and heat number were recorded. Where light elements or carbon are decisive, the method and its limitations must be considered rather than relying on a generic alloy library result.
PMI does not verify microstructure, tensile properties or heat treatment. Those characteristics require separate records and tests.
Ultrasonic examination and final review
UT was performed from suitable scanning surfaces to examine the forging for reportable internal reflectors within the specified coverage. Surface condition, calibration blocks, sensitivity, scan plan and acceptance standard were controlled by the examination procedure.
The final review combined UT reports with hardness, boyutlar, ısıl işlem, markings and material certificates. This evidence package supported release of the finished F91 flanges without treating any single test as a complete quality verdict.
Information needed for a comparable RFQ
A comparable inquiry should identify the exact material specification and grade, governing standard and edition, NPS'ler, basınç sınıfı, flanş tipi, karşı karşıya, bore or matching pipe schedule, quantity and destination. For this project-news scope, the key reference points were ASTM A182 F91 forged alloy steel, Weld neck and blind, RF/RTJ as ordered, Class 600–1500 Ve NPS 4–18.
State the required EN 10204 certificate type, ısı numarası izlenebilirliği, PMI extent, sertlik sınırları, boyutlu rapor, NDE method and acceptance standard, third-party witness points, packing method and required delivery date at quotation stage. Early definition allows manufacturing, inspection and document schedules to be reviewed together.

Sık sorulan sorular
What is the difference between PMI and UT?
PMI checks alloy chemistry at the test location. UT uses sound waves to examine internal material quality.
Can UT identify the alloy grade?
HAYIR. UT is not a chemical identification method; grade identity comes from traceability, certificates and appropriate PMI or laboratory testing.
Why is hardness reviewed for F91?
Hardness provides supporting evidence about material and thermal condition, especially when reviewed with heat-treatment and mechanical-property records.
