Produktdetails
Tantalum lap joint flanges are loose-type flanges designed to rotate over a matching stub end, making alignment easier during installation and maintenance. They are selected for extremely corrosive media including hot sulfuric acid, hydrochloric acid in controlled conditions, Salpetersäure, bromine-bearing media and high-purity chemical service. Compared with integral flanges, lap joint designs reduce replacement cost when expensive corrosion-resistant materials such as tantalum are required only on the wetted side.
SASA FLANGE supplies tantalum lap joint flanges and tantalum-clad constructions in customized dimensions and drilling patterns to suit ASME B16.5, EN 1092-1, DIN, JIS and GB systems. Jeder Auftrag kann mit einer chemischen Analyse unterstützt werden, mechanische Prüfung, Maßprüfung, PMI-Tests, EN 10204 3.1 certificate and full heat number traceability to meet demanding international project requirements.

Produktinspektion
1. Inspektion der chemischen Zusammensetzung
Chemical composition inspection verifies the tantalum grade and impurity limits required for corrosive service. Raw material certificates are reviewed and, wo angegeben, laboratory analysis is performed to confirm compliance with ASTM or customer requirements. This control is critical because small variations in interstitials and metallic impurities can affect corrosion resistance and fabrication performance.
2. Prüfung der mechanischen Eigenschaften
Mechanical properties testing confirms tensile strength, Streckgrenze, elongation and hardness of the tantalum material used for flange production. Test results are checked against the relevant grade and supply condition, such as annealed or stress-relieved. This helps ensure the flange can withstand assembly loads, thermal cycling and service stresses without cracking or excessive deformation.
3. Maßprüfung
Die Maßprüfung erstreckt sich auf den Außendurchmesser, Dicke, langweilig, Lochkreis, Schraubenlochgröße, flange flatness and sealing face finish. Für Überlappungsflansche, special attention is paid to fit-up with the matching stub end and free rotation during installation. Standard-specific tolerances are verified to ASME, EN, DIN, JIS, GB or approved project drawings before release.
4. PMI-Tests und hydrostatische Tests
PMI testing is carried out to confirm the supplied material matches the specified tantalum grade or clad construction. When supplied as part of an assembled piping component, hydrostatic testing can be performed according to project requirements to verify pressure integrity. EN 10204 3.1 Zertifikat, inspection reports and full heat number traceability are provided for documented quality assurance.

FAQ
Q: What is a tantalum lap joint flange?
A: A tantalum lap joint flange is a rotating backing flange used together with a stub end, where the wetted corrosion-resistant component is typically tantalum or tantalum-lined. The design allows easier bolt hole alignment and lower replacement cost compared with solid integral flanges, making it suitable for highly corrosive chemical and high-purity process systems.
Q: What materials are available for tantalum lap joint flanges?
A: SASA FLANGE can supply solid tantalum grades such as ASTM B521 R05200, R05400 and R05252, depending on application requirements. For more economical solutions, tantalum-clad carbon steel or tantalum-clad stainless steel constructions are also available. Die Materialauswahl hängt von der Prozesschemie ab, Betriebstemperatur, pressure class and the extent of tantalum exposure required.
Q: Welche Druckklasse wird unterstützt??
A: Typical supply range for tantalum lap joint flanges is ASME Class 150, 300 Und 600, as well as metric PN10 to PN63 depending on size and design standard. Because tantalum is usually used in specialized corrosive service, the final pressure rating may also depend on backing flange construction, temperature and the associated stub end design.
Q: Kann SASA FLANGE liefern kundenspezifische Größen?
A: Ja. SASA FLANGE supplies custom dimensions, Bohrmuster, bore sizes, facing details and special mating arrangements for tantalum lap joint flange assemblies. We can manufacture to ASME, EN, DIN, JIS, GB or customer drawings, including special stub end fit-up, mixed-standard drilling and tailored clad or solid tantalum solutions for process equipment manufacturers and EPC projects.
Q: Welches Zertifikat wird bereitgestellt??
A: Die Standarddokumentation umfasst EN 10204 3.1 Materialzertifikat mit Rückverfolgbarkeit der Schmelzennummer. Depending on order scope, SASA FLANGE can also provide chemical analysis reports, mechanische Testergebnisse, PMI inspection records, dimensional inspection reports and hydrostatic test records for assembled components. This documentation helps global buyers meet project QA/QC and end-user approval requirements.
