제품 세부정보
PVDF threaded flanges are internally threaded plastic flanges manufactured for connection to threaded plastic or lined piping systems where excellent chemical resistance, low contamination and corrosion-free performance are required. Compared with metallic flanges, PVDF offers strong resistance to acids, 알칼리, chlorides and many organic chemicals, making these flanges suitable for chemical dosing lines, water treatment skids, semiconductor utilities and light industrial process systems.
SASA FLANGE supplies PVDF threaded flanges in standard and customized dimensions with precision-machined threads, flange drilling and sealing faces. Each order can be supported with raw material verification, chemical analysis of resin reference data, 치수검사, mechanical testing where specified, PMI testing for metallic inserts if applicable, EN 10204 3.1 certificate and full batch number traceability to ensure dependable project documentation.

제품검사
1. 화학성분 검사
For PVDF threaded flanges, raw material verification is based on resin batch records, supplier conformity documents and reference composition data for PVDF polymer. SASA FLANGE checks incoming material identity, grade designation and batch consistency to ensure the supplied flange matches customer requirements for corrosion resistance, purity level and intended process service.
2. 기계적 성질 테스트
Mechanical property verification may include review of resin data sheets and, 지정된 곳에, testing of representative material for tensile strength, yield behavior, 신장과 경도. This helps confirm that the selected PVDF grade is suitable for the required operating temperature, bolt loading and low-pressure piping duty in chemical and water systems.
3. 치수검사
Each PVDF threaded flange is inspected for outside diameter, 두께, 볼트 서클, 볼트 구멍 직경, 플랜지 평탄도, thread accuracy and sealing face geometry. Proper dimensional control is essential for leak-tight assembly with mating flanges, correct gasket compression and smooth installation on threaded plastic or lined piping systems.
4. PMI 테스트 및 수압 테스트
Standard PMI by alloy analyzer is generally not applicable to pure PVDF polymer, 하지만 SASA FLANGE can perform material identity verification through batch control and resin documentation. Hydrostatic testing is typically conducted on assembled piping joints or flange assemblies when specified. EN 10204 3.1 자격증, dimensional reports and batch traceability documents are available for project supply.

FAQ
큐: What is a PVDF threaded flange?
에이: A PVDF threaded flange is a non-metallic flange made from polyvinylidene fluoride and machined with internal threads for connection to threaded piping or fittings.
