Em segundo lugar, os requisitos gerais dos acess\u00f3rios para cablagem de tubos de a\u00e7o <\/p>\n\n\n\n
1) O inv\u00f3lucro do acess\u00f3rio deve ser geralmente feito de alum\u00ednio fundido, a\u00e7o fundido, materiais de ferro fundido e tamb\u00e9m pode ser feito de materiais que cumpram os regulamentos correspondentes; <\/p>\n\n\n\n
2) Quando o inv\u00f3lucro \u00e9 feito de ferro fundido ou de material de liga leve, a sua for\u00e7a deve ser capaz de suportar o ensaio de resist\u00eancia ao impacto correspondente sem fissuras ou deforma\u00e7\u00f5es \u00f3bvias; <\/p>\n\n\n\n
3) A superf\u00edcie do inv\u00f3lucro deve ter medidas anti-ferrugem, e a superf\u00edcie interior do inv\u00f3lucro deve ser lisa e suave, sem arestas vivas ou rebarbas, de modo a n\u00e3o riscar o fio; <\/p>\n\n\n\n
4) A rosca de liga\u00e7\u00e3o deve ser uma rosca m\u00e9trica, uma rosca de tubo cil\u00edndrica ou uma rosca de tubo c\u00f3nica; <\/p>\n\n\n\n
5) A tampa e o corpo dos acess\u00f3rios antideflagrantes devem ser de rosca m\u00e9trica ou de rosca cil\u00edndrica, e o seu passo, n\u00famero de malhas, comprimento da malha e precis\u00e3o da rosca devem cumprir os regulamentos correspondentes; a utiliza\u00e7\u00e3o de roscas c\u00f3nicas para tubos deve estar em conformidade com os regulamentos correspondentes. <\/p>\n\n\n\n
Iii. Outros requisitos em anexo <\/p>\n\n\n\n
Para al\u00e9m de cumprirem os requisitos gerais acima referidos, os acess\u00f3rios da caixa devem ter uma abertura e uma cavidade interna suficientemente grandes; os acess\u00f3rios devem poder passar facilmente atrav\u00e9s do fio ou do cabo com a \u00e1rea m\u00e1xima permitida da sec\u00e7\u00e3o transversal; o vedante de isolamento deve ter uma estrutura que assegure o tamanho efetivo de enchimento do material de enchimento e o comprimento efetivo de enchimento n\u00e3o deve ser inferior ao di\u00e2metro da conduta, com um m\u00ednimo de 16 mm. <\/p>\n\n\n\n
Os acess\u00f3rios utilizados em ambientes especiais (tais como ambientes quentes e h\u00famidos ou corrosivos) devem tamb\u00e9m tomar medidas de prote\u00e7\u00e3o adequadas de acordo com os requisitos das normas relevantes.<\/p>","protected":false},"excerpt":{"rendered":"
