Descripción
Detalle del producto
PVDF slip on flanges are thermoplastic pipe flanges that slide over the pipe outside diameter and are then joined by welding, bonding or stub-end backing arrangements depending on the system design. They offer excellent resistance to acids, álcalis, salts, oxidizing chemicals and UV exposure, while maintaining smooth internal flow characteristics. These flanges are commonly used in chemical plants, water treatment units, semiconductor process lines, marine corrosion service and clean utility systems.
SASA FLANGE supplies PVDF slip on flanges in standard and customized dimensions with strict quality control for industrial projects. Available services include chemical analysis of raw resin lots, mechanical property verification, inspección dimensional, pressure capability review, PMI testing for metallic backing components where applicable, EN 10204 3.1 certificate and full batch traceability to ensure reliable installation and long service life.

Inspección del producto
1. Inspección de composición química
For PVDF slip on flanges, raw material verification is carried out against approved resin specifications and supplier batch data. Key polymer identity, resin grade and additive content for conductive versions are checked through incoming material records and production controls. This helps ensure the supplied flange material is suitable for chemical resistance and clean process service.
2. Pruebas de propiedades mecánicas
Mechanical testing is performed on representative PVDF material according to relevant plastic material test methods. Typical checks include tensile strength, yield behavior, elongation and hardness at ambient conditions. These tests confirm that the processed flange material meets the expected structural performance for bolted piping connections within the specified temperature and pressure range.
3. Inspección dimensional
Each PVDF slip on flange is inspected for outer diameter, tamaño del orificio, espesor de brida, círculo de pernos, diámetro del agujero, number of holes and face flatness. Visual examination also confirms clean machining, burr-free edges and proper sealing surface condition. Accurate dimensions are essential to ensure correct alignment with mating flanges and stable gasket compression in service.
4. Pruebas PMI y pruebas hidrostáticas
PMI testing is available for metallic backing flanges or inserts when supplied as part of an assembly, while polymer material verification follows resin traceability controls. Hydrostatic testing is generally carried out at system or assembly level rather than on individual plastic flanges alone. SASA FLANGE puede proporcionar EN 10204 3.1 certificado, dimensional records and supporting inspection documentation.
