제품 세부정보
A titanium blind flange is a flange without a center bore, designed to blank off the end of pipelines, 밸브, 슬리퍼, and pressure vessel nozzles. Compared with carbon steel and stainless steel alternatives, titanium blind flanges provide superior resistance to seawater, 염화물, oxidizing media and many aggressive chemical solutions, while also reducing system weight. They are widely used in offshore platforms, 담수화 장치, chlor-alkali plants, 열교환기, pulp and paper lines, 및 고순도 공정 시스템.
SASA FLANGE supplies titanium blind flanges in standard and custom dimensions to ASME B16.5, ASME B16.47, EN 1092-1, DIN, JIS 및 GB 표준. Each flange can be provided with chemical analysis, 기계적 테스트, 치수검사, PMI 테스트, EN 10204 3.1 인증서 및 전체 열 번호 추적성. Custom drilling, 직면 유형, thickness and non-standard pressure ratings are available on request.
