Ürün Detayı
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, alkaliler, 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, boyutsal muayene, 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.

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. Boyutsal Muayene
Each PVDF threaded flange is inspected for outside diameter, kalınlık, cıvata dairesi, cıvata deliği çapı, flange flatness, 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 Testi ve Hidrostatik Test
Standard PMI by alloy analyzer is generally not applicable to pure PVDF polymer, Ancak 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 sertifika, dimensional reports and batch traceability documents are available for project supply.

SSS
Q: What is a PVDF threaded flange?
A: 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. It is used in corrosive service where metal flanges may suffer attack or contamination. PVDF threaded flanges are common in chemical dosing, water treatment and clean utility systems operating at moderate pressure.
Q: What materials are available for PVDF threaded flanges?
A: SASA FLANGE can supply PVDF threaded flanges in virgin PVDF, natural PVDF and selected glass-filled PVDF grades depending on strength, purity and service requirements. Virgin and natural PVDF are preferred for corrosive and cleaner service, while reinforced grades may be used for improved stiffness in specific industrial applications subject to design review.
Q: Hangi basınç sınıfı destekleniyor?
A: PVDF threaded flanges are typically used in lower-pressure plastic piping systems and are commonly supplied in PN10 to PN16 ratings or ASME Class 150 equivalent drilling patterns. Actual allowable pressure depends on flange size, duvar kalınlığı, sıcaklık, gasket type and the connected piping system, so final selection should be confirmed against the service conditions.
