SELEÇÃO DO ADAPTADOR
ADAPTER SELECTION
A seleção de um adaptador ALFAGOMMA apropriado para uma dada aplicação depende dos parâmetros do sistema de fluido
operacionais listados abaixo e o material do tubo e da espessura da parede que requerem:
Selection of an appropriate ALFAGOMMA adapter for a given application depends on the uid system operating
parameters listed below and the tube material and wall thickness they require:
1. Type of uid
1. Tipo de fluido
2. Temperatura
2. Operating temperature range
3. Tipo de linha - a pressão de retorno, ou de sucção
3. Type of line - pressure, return or suction
4. Taxa de fluxo máximo através da linha
4. Maximum ow rate through the line
5. Maximum operating / service pressure
5. Pressão de operação / serviço máximo
6. Severity of service
6. Gravidade de serviço
7. Environment
7. Ambiente
Then, based on the tube selected and appropriate uid system operating parameters, determine adapter type(s)
and material(s) using the features comparison table below.
Em seguida, com base no tubo selecionado e apropriados parâmetros funcional do sistema do fluido, determinar o tipo de adaptador
(s) e material (s), utilizando a tabela de comparação de características abaixo.
