Детали продукта
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, щелочи, 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, проверка размеров, 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.

Проверка продукта
1. Проверка химического состава
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. Испытание механических свойств
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. Проверка размеров
Each PVDF slip on flange is inspected for outer diameter, размер отверстия, толщина фланца, болт круг, диаметр отверстия, 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. PMI-тестирование и гидростатические испытания
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 может предоставить EN 10204 3.1 сертификат, dimensional records and supporting inspection documentation.

Часто задаваемые вопросы
вопрос: What is a PVDF slip on flange?
А: A PVDF slip on flange is a thermoplastic flange designed to slide over a plastic pipe before joining and bolting to a mating flange. It is used in corrosive and clean service piping where metallic flanges may suffer chemical attack. PVDF offers strong chemical resistance, low contamination risk and good durability in outdoor and industrial environments.
вопрос: What materials are available for PVDF slip on flanges?
А: SASA FLANGE supplies PVDF slip on flanges in natural PVDF and conductive PVDF grades. Natural PVDF is widely used for chemical and purified water applications, while conductive PVDF is selected where static dissipation is required. We can also discuss related solutions such as PVDF lined steel flanges or matched backing flange assemblies for specific projects.
вопрос: Какой класс давления поддерживается?
А: PVDF slip on flanges are typically supplied in PN6 to PN16 ratings depending on size, толщина стенки, design temperature and system configuration. Класс ANSI 150 drilling can also be provided for compatibility with common piping layouts, but the actual working pressure must follow PVDF material derating rules and the project operating temperature requirements.
вопрос: Может SASA FLANGE поставляем нестандартные размеры?
А: Да. SASA FLANGE can produce custom PVDF slip on flanges according to drawings or project specifications, including special bore sizes, non-standard bolt drilling, custom outside diameters and sealing face details. We can also match ASME, EN, DIN, JIS or GB drilling patterns and support special material requests for conductive grades or assembled backing flange solutions.
вопрос: Какой сертификат предоставляется?
А: SASA FLANGE может предоставить EN 10204 3.1 сертификат материала, raw material batch traceability, dimensional inspection reports and packing identification records for PVDF slip on flanges. For assemblies including metallic backing parts, PMI testing can be included. Hydrostatic testing is typically performed at assembled system level, and supporting inspection documents can be issued as required by the order.
