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, щелочи, chlorides and many organic chemicals, making these flanges suitable for chemical dosing lines, установки водоочистки, 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, проверка размеров, 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.

Проверка продукта
1. Проверка химического состава
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. Испытание механических свойств
Mechanical property verification may include review of resin data sheets and, where specified, testing of representative material for tensile strength, yield behavior, удлинение и твердость. 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. Проверка размеров
Each PVDF threaded flange is inspected for outside diameter, толщина, болт круг, диаметр отверстия под болт, плоскостность фланца, 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-тестирование и гидростатические испытания
Standard PMI by alloy analyzer is generally not applicable to pure PVDF polymer, but 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 сертификат, dimensional reports and batch traceability documents are available for project supply.

Часто задаваемые вопросы
вопрос: What is a PVDF threaded flange?
А: 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.
вопрос: What materials are available for PVDF threaded flanges?
А: 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.
вопрос: Какой класс давления поддерживается?
А: 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, толщина стенки, температура, gasket type and the connected piping system, so final selection should be confirmed against the service conditions.
вопрос: Может SASA FLANGE поставляем нестандартные размеры?
А: Да. SASA FLANGE can produce custom PVDF threaded flanges according to drawings or sample dimensions, including non-standard bolt drilling, special thread forms, нестандартная толщина, full-face or raised-face design and matching to ASME, EN, DIN, JIS or GB drilling patterns. Special colors, marked identification and assembly-related machining can also be arranged on request.
вопрос: Какой сертификат предоставляется?
А: SASA FLANGE может предоставить EN 10204 3.1 сертификат, material conformity documents, dimensional inspection reports and batch traceability records for PVDF threaded flanges. For projects requiring additional quality assurance, we can support raw material verification, assembly hydrostatic testing where applicable and documentation aligned with customer purchase order and technical specification requirements.
