説明
製品詳細
Blind flange PEEK lined products are solid flanges designed to close the end of a pipeline, nozzle or pressure vessel opening. By combining a high-strength forged metal body with a PEEK contact surface, insert or liner, they offer reliable shutoff, excellent dimensional stability, strong wear resistance and improved performance in corrosive or high-purity applications. They are widely used in chemical dosing lines, aggressive process media systems, offshore skids, water treatment units and selected high-temperature piping services.
SASA FLANGE supplies standard and customized blind flange PEEK configurations in accordance with ASME B16.5, ASME B16.47, EN 1092-1, DIN, JIS および GB の要件. 各オーダーは化学分析によってサポート可能, 機械的試験, 寸法検査, PMIテスト, シール面の検証, EN 10204 3.1 certificate and full heat number traceability from raw material to final delivery.

製品検査
1. 化学成分検査
Chemical analysis is carried out on the flange body material to confirm compliance with the specified grade such as A105, F316L or duplex stainless steel. Positive identification of alloying elements helps ensure corrosion resistance, weld compatibility and pressure boundary reliability. Test results are recorded against the heat number and linked to the material certificate for full traceability.
2. 機械的特性試験
Mechanical testing verifies that the flange body achieves the required tensile strength, 降伏強さ, elongation and hardness according to the applicable forging or plate standard. 必要な場合, impact testing for low-temperature service can also be arranged. This inspection confirms the blind flange has the structural integrity needed for line blanking and pressure containment.
3. 寸法検査
Each blind flange is checked for outside diameter, 厚さ, ボルトサークル, ボルト穴数, 穴径, facing dimensions and overall flatness. Special attention is given to the sealing face and the fit of the PEEK lined or insert area. Inspection is performed according to ASME, EN, DIN, JIS, GB or approved customer drawings to ensure trouble-free installation.
4. PMI試験と静水圧試験
PMI testing is available to confirm the alloy grade of stainless steel, duplex or high-alloy blind flanges before shipment. プロジェクトの要件については, hydrostatic or seat integrity testing can be arranged on assembled or special lined configurations. SASA FLANGE 用品 EN 10204 3.1 証明書, inspection records and heat number traceability to support international project documentation.
