Descrição
Detalhes do produto
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, ácido nítrico, 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. Cada pedido pode ser apoiado com análise química, testes mecânicos, inspeção dimensional, Teste PMI, EN 10204 3.1 certificate and full heat number traceability to meet demanding international project requirements.

Inspeção de Produto
1. Inspeção de Composição Química
Chemical composition inspection verifies the tantalum grade and impurity limits required for corrosive service. Raw material certificates are reviewed and, onde especificado, 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. Teste de propriedades mecânicas
Mechanical properties testing confirms tensile strength, força de rendimento, 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. Inspeção Dimensional
A inspeção dimensional cobre o diâmetro externo, grossura, chato, círculo de parafuso, tamanho do furo do parafuso, flange flatness and sealing face finish. Para flanges de junta sobreposta, 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. Teste PMI e Teste Hidrostático
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 certificado, inspection reports and full heat number traceability are provided for documented quality assurance.

Perguntas frequentes
P: What is a tantalum lap joint flange?
UM: 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.
P: What materials are available for tantalum lap joint flanges?
UM: SASA FLANGE can supply solid tantalum grades such as ASTM B521 R05200, R05400 and R05252, dependendo dos requisitos da aplicação. For more economical solutions, tantalum-clad carbon steel or tantalum-clad stainless steel constructions are also available. A seleção do material depende da química do processo, temperatura operacional, pressure class and the extent of tantalum exposure required.
P: Qual classe de pressão é suportada?
UM: Typical supply range for tantalum lap joint flanges is ASME Class 150, 300 e 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.
