Traduzido pelo Google,

Ao fazer o pedido, especifique A, B, C, D e o(s) tipo(s) final(is). (A – C) ≥ (CB) e (C) ≥ (D) Pode ser necessário redutor em C ou D. Use a fórmula acima para determinar. Use a seguinte fórmula para determinar o comprimento: L = CX 2 + 15”.

Uma extremidade vanstone com flanges angulares rotacionais é padrão. Se forem necessários flanges soldados, a marcação deverá ser especificada. Os flanges são flanges angulares padrão da indústria.

O material de aço de calibre 12 adiciona durabilidade extra.

Construção em aço galvanizado
Disponível com ângulo de 30° ou 45°
Medidores de ramificação adicionais disponíveis: 22, 20, 18, 16, 14 e 10
