Os materiais mais comuns utilizados nas mangueiras de suc\u00e7\u00e3o incluem NBR, TPU, PVC, fio de a\u00e7o (para uma estrutura helicoidal) e borracha sint\u00e9tica. Lembre-se de que as mangueiras de suc\u00e7\u00e3o em PVC s\u00e3o apenas <\/span><a href=\"https:\/\/rentonehose.com\/pt\/water-hose\/\"><b>adequado para o transporte de \u00e1gua<\/b><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Em contrapartida, as mangueiras fabricadas em NBR podem transportar combust\u00edvel e \u00f3leo. As mangueiras de suc\u00e7\u00e3o fabricadas em diferentes materiais oferecem propriedades \u00fanicas. As mangueiras de descarga s\u00e3o normalmente fabricadas com materiais leves, como PVC, borracha sint\u00e9tica ou borracha EPDM. Al\u00e9m disso, podem incluir refor\u00e7o t\u00eaxtil ou de nylon para maior resist\u00eancia. Apenas as mangueiras de descarga de gama alta v\u00eam com refor\u00e7o de fio de a\u00e7o. Este refor\u00e7o de fio de a\u00e7o torna-as excepcionalmente mais resistentes e duradouras.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"7-_Flexibility_Weight\"><\/span><b>7- Flexibilidade e peso\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">As mangueiras de suc\u00e7\u00e3o s\u00e3o mais pesadas e menos flex\u00edveis. Porqu\u00ea? A raz\u00e3o \u00e9 que estas mangueiras s\u00e3o constitu\u00eddas por uma camada de refor\u00e7o resistente, o que as torna r\u00edgidas. Esta camada de refor\u00e7o tamb\u00e9m impede que se tor\u00e7am ou colapsem sob press\u00e3o negativa. No entanto, os materiais mais pesados e o refor\u00e7o aumentam o seu peso. Por isso, transportar e instalar estas mangueiras pode ser um pouco mais complicado.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Por outro lado, as mangueiras de descarga s\u00e3o muito flex\u00edveis. S\u00e3o fabricadas com materiais leves, o que lhes confere flexibilidade. Isto tamb\u00e9m facilita o transporte e a instala\u00e7\u00e3o. A excelente flexibilidade das mangueiras de descarga tamb\u00e9m ajuda a instal\u00e1-las com facilidade em espa\u00e7os muito apertados. A instala\u00e7\u00e3o de mangueiras de suc\u00e7\u00e3o em espa\u00e7os apertados pode ser muito dif\u00edcil devido \u00e0 sua rigidez. Se forem submetidas a cargas ou tens\u00f5es, podem ficar danificadas devido \u00e0 sua rigidez.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"8-_Cost_Applications\"><\/span><b>8.

No entanto, as pessoas n\u00e3o t\u00eam outra op\u00e7\u00e3o sen\u00e3o compr\u00e1-las, uma vez que suportam facilmente a press\u00e3o negativa. A raz\u00e3o para o seu elevado pre\u00e7o reside na sua estrutura, refor\u00e7o e materiais. S\u00e3o fornecidas com refor\u00e7o em espiral ou helicoidal e materiais resistentes.

Por outro lado, as mangueiras de descarga s\u00e3o muito acess\u00edveis, o que constitui uma grande vantagem. Isto deve-se ao seu design simples e aos materiais menos resistentes, que s\u00e3o baratos. No que diz respeito \u00e0 aplica\u00e7\u00e3o, as mangueiras de suc\u00e7\u00e3o s\u00e3o utilizadas para lidar com press\u00e3o negativa.
