제품 세부정보
Hastelloy lap joint flanges are backing flanges designed to be used with a compatible stub end, allowing easy alignment and dismantling in piping systems handling highly corrosive media. Compared with integral flanges, the lap joint design reduces replacement cost in alloy piping because the flange does not contact the process fluid directly when matched with the correct stub end material. These flanges are widely used in chemical plants, 해양 플랫폼, flue gas treatment, acid service and high-purity process lines.
SASA FLANGE supplies Hastelloy lap joint flanges in standard and customized dimensions according to ASME, EN, DIN, JIS, GB 및 프로젝트 도면. Each batch can be delivered with chemical analysis, 기계적 테스트, 치수검사, PMI 테스트, EN 10204 3.1 중요한 산업 조달 요구 사항을 지원하는 인증서 및 전체 열 번호 추적성.

제품검사
1. 화학성분 검사
Chemical composition inspection is carried out to confirm that the supplied Hastelloy flange material matches the specified alloy grade such as C22 or C276. Test results are checked against the applicable ASTM or ASME standard limits for key elements including nickel, 크롬, 몰리브덴, iron and tungsten to ensure corrosion resistance and material conformity.
2. 기계적 성질 테스트
Mechanical testing is performed in accordance with the applicable material specification to verify tensile strength, 항복강도, elongation and hardness of the nickel alloy material. These tests confirm that the flange blank or forged material has the required structural properties for pressure service, fabrication reliability and stable performance under demanding operating conditions.
3. 치수검사
치수 검사는 외경을 커버합니다., 두께, 구경, 볼트 서클, 볼트 구멍 직경, number of holes and overall tolerance according to ASME, EN, DIN, JIS 또는 GB 표준. For lap joint flanges, special attention is given to fit-up with the mating stub end, smooth rotation during alignment and correct flange face geometry for site installation.
4. PMI 테스트 및 수압 테스트
PMI testing is available to verify alloy identity on each flange or batch using portable spectrometer or XRF equipment, helping avoid grade mix-up in critical service. Hydrostatic testing is generally applied to assembled piping or special flange components when specified.

Custom machining and documentation packages are available for EPC, OEM and maintenance buyers.
큐: 어떤 인증서가 제공되나요??
에이: Hastelloy lap joint flanges can be supplied with EN 10204 3.1 재료 인증서, mill test certificate, dimensional inspection report and PMI test results. Additional documentation can be arranged according to order requirements. Where specified, we also support third-party inspection, 경도 또는 기계적 테스트 기록, heat number traceability and complete shipping marking for project control.
