Flanged Branch 18ga

Traduzido pelo Google,

As ramificações (às vezes chamadas de “wyes” ou “laterais”) são padrão com extremidades de flange angular rotacional (AFL), permitindo conexões com outros dutos flangeados. O material de aço de calibre 18 adiciona durabilidade extra.

Ao fazer o pedido, especifique o material, a bitola, as dimensões A, B, C, os estilos de extremidade, se não todos AFL, e o ângulo (padrão 30°, opcional 45°).

A - C ≥ C - B. Use a fórmula para determinar se um redutor é necessário em C.
Comprimento = CX 2 + 9"
Disponível com extremidades QF em diâmetros de até 24" e vários outros tipos de extremidades
Disponível com ângulo de 30° ou 45°
Outros medidores disponíveis: padrão 22 e 20, 16, 14, 12 e 10

Entre em contato com a Nordfab ou seu revendedor Nordfab local para obter assistência no pedido de filiais de calibre 18.
