F91 단조 플랜지에 대한 PMI 및 초음파 테스트 완료

프로젝트 뉴스Published: 3 팔월 2026SASA FLANGE Project Team
Project completed

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 and UT were reported separately because they verify different acceptance characteristics.
Test identification remained linked to flange marking and heat number.
Hardness and heat-treatment records complemented the chemistry and NDE results.

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, 치수, 열처리, 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, 관리 표준 및 에디션, NPS, 압력 등급, 플랜지형, 깃 달기, 보어 또는 일치하는 파이프 일정, 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 그리고 NPS 4–18.

State the required EN 10204 certificate type, 열수 추적성, PMI extent, 경도 한계, 치수 보고서, 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.

자주 묻는 질문

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?

아니요. 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.
