説明
製品詳細
A tantalum socket weld flange is a forged or machined flange with a socket bore designed for insertion and fillet welding of small-diameter pipe. It is selected where outstanding corrosion resistance is required, especially in hot concentrated acids, chlorides and high-purity process systems. The socket weld design provides secure alignment, reduced leakage risk and strong performance in compact piping layouts used in chemical processing, pharmaceutical plants, specialty acids and offshore chemical injection lines.
SASA FLANGE supplies tantalum socket weld flanges in standard and customized dimensions with strict quality control. Each order can be supported by chemical analysis, 機械的試験, 寸法検査, PMIテスト, EN 10204 3.1 certificate and full heat number traceability. Custom machining for facing type, 穴あけパターン, bore size and special project requirements is available.

製品検査
1. 化学成分検査
Chemical composition inspection is carried out to verify tantalum purity and impurity limits against ASTM or ASME material requirements. Key controlled elements include oxygen, nitrogen, hydrogen and metallic residuals that may influence corrosion behavior and fabrication performance. Test records are reviewed against the mill certificate to ensure the flange material matches the specified grade and project documentation.
2. 機械的特性試験
Mechanical property testing confirms that the tantalum material used for flange production meets specified tensile strength, 降伏強さ, elongation and hardness requirements. Depending on order specification, test samples are taken from the same heat or production lot. These tests help ensure adequate ductility, machining behavior and structural reliability for welded flange service in corrosive process systems.
3. 寸法検査
Dimensional inspection covers outside diameter, フランジの厚さ, ボルトサークル, ボルト穴のサイズ, socket bore, socket depth, facing height and raised face finish. Each flange is checked against the applicable ASME, EN, DIN, JIS, GB or approved drawing requirement. Accurate dimensions are essential to ensure proper fit-up, gasket seating and reliable welding alignment during field installation.
4. PMI試験と静水圧試験
PMI testing is performed to confirm the delivered flange material corresponds to the specified tantalum grade and to prevent material mix-up in critical service. When required by the order or project specification, hydrostatic testing is arranged on assembled components or related spool pieces. EN 10204 3.1 証明書, inspection reports and traceability records are supplied with shipment.
