Inspección del producto

1. Inspección de composición química

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. Pruebas de propiedades mecánicas

Mechanical property verification may include review of resin data sheets and, where specified, testing of representative material for tensile strength, yield behavior, elongation and hardness. 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. Inspección dimensional

Each PVDF threaded flange is inspected for outside diameter, espesor, círculo de pernos, diámetro del agujero del perno, planitud de la brida, 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. Pruebas PMI y pruebas hidrostáticas

Standard PMI by alloy analyzer is generally not applicable to pure PVDF polymer, pero 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 certificado, dimensional reports and batch traceability documents are available for project supply.

Preguntas frecuentes

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: ¿Qué clase de presión se admite??

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, espesor de pared, temperatura, gasket type and the connected piping system, so final selection should be confirmed against the service conditions.

q: Poder SASA FLANGE suministrar tamaños personalizados?

A: Sí. SASA FLANGE can produce custom PVDF threaded flanges according to drawings or sample dimensions, including non-standard bolt drilling, special thread forms, custom thickness, 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.

q: ¿Qué certificado se proporciona??

A: SASA FLANGE puede proporcionar EN 10204 3.1 certificado, 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.
