A raz\u00e3o reside no facto de estes dois gases gerarem, geralmente, temperaturas elevadas. Quando misturados, criam uma chama muito mais quente do que o acetileno por si s\u00f3. \u00c9 poss\u00edvel atingir cerca de 3 200 \u00b0C (5 800 \u00b0F). J\u00e1 sabe que s\u00e3o necess\u00e1rias altas temperaturas para soldar e cortar metais de forma eficaz.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">A principal fun\u00e7\u00e3o de uma mangueira de oxiacetileno \u00e9 transportar gases (oxig\u00e9nio e acetileno) do cilindro para o ma\u00e7arico. Esta mangueira permite o transporte seguro de g\u00e1s a alta press\u00e3o e garante uma qualidade de chama est\u00e1vel. Tamb\u00e9m \u00e9 poss\u00edvel beneficiar dos seus mecanismos de seguran\u00e7a, que evitam fugas e mant\u00eam a integridade da mangueira.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Properties_of_Oxygen_and_acetylene_hoses\"><\/span>Caracter\u00edsticas das mangueiras de oxig\u00e9nio e acetileno<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\r\n<p>As mangueiras de oxiacetileno s\u00e3o altamente flex\u00edveis. Isto significa que podem ser dobradas, se necess\u00e1rio, sem que percam a sua funcionalidade. S\u00e3o tamb\u00e9m duradouras e capazes de resistir ao desgaste resultante da utiliza\u00e7\u00e3o frequente. Em terceiro lugar, funcionam sem problemas mesmo em ambientes adversos.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">As mangueiras de oxiacetileno est\u00e3o dispon\u00edveis em diferentes tamanhos. Trata-se, normalmente, de mangueiras de classe R, especialmente recomendadas para oxig\u00e9nio e acetileno. O seu di\u00e2metro interior varia entre 4,8 mm e 9,5 mm, e o di\u00e2metro exterior entre 11,5 mm e 17 mm. Estes tamanhos de mangueira podem apresentar ligeiras toler\u00e2ncias at\u00e9 \u00b1 0,3 mm. Por fim, a temperatura de funcionamento recomendada \u00e9 de -25 \u00b0C a +70 \u00b0C (-13 \u00b0F a +158 \u00b0F).<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">As mangueiras de oxiacetileno s\u00e3o n\u00e3o condutoras, e o tubo e o revestimento s\u00e3o normalmente isentos de \u00f3leo. Isto significa que s\u00e3o mais seguras na proximidade de equipamento el\u00e9trico e n\u00e3o atraem p\u00f3 nem outros contaminantes. Mais importante ainda, estas mangueiras s\u00e3o resistentes ao fogo. Como sabe, a soldadura e o corte envolvem altas temperaturas e chamas. Consequentemente, as mangueiras de oxiacetileno s\u00e3o seguras para estes processos.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">As mangueiras de oxiacetileno tamb\u00e9m apresentam caracter\u00edsticas anti-envelhecimento.

Cada camada desempenha um papel crucial no funcionamento geral da mangueira. Estas camadas garantem que a mangueira seja dur\u00e1vel, flex\u00edvel e capaz de suportar alta press\u00e3o. Se cortar uma mangueira de oxiacetileno na vertical, poder\u00e1 observar uma sec\u00e7\u00e3o transversal composta por quatro camadas.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Inner_Tube\"><\/span>C\u00e2mara de ar<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\r\n<p>A primeira camada que se v\u00ea a partir do n\u00facleo interno \u00e9 o tubo interno. \u00c9 o tubo principal que transporta oxig\u00e9nio ou acetileno. Esta camada \u00e9 composta principalmente por borracha SBR. SBR significa \u00abborracha de estireno-butadieno\u00bb.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Como sabem, o SBR tem um excelente desempenho em contacto com \u00e1gua, g\u00e1s e determinados produtos qu\u00edmicos. Assim, o tubo interior de uma mangueira de oxiacetileno garante uma condu\u00e7\u00e3o segura do oxig\u00e9nio e do acetileno.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reinforcement_Layer\"><\/span>Camada de refor\u00e7o<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\r\n<p>A camada de refor\u00e7o encontra-se logo acima do tubo interior.

Esta camada \u00e9 normalmente constitu\u00edda por cord\u00f5es helicoidais de poli\u00e9ster de elevada resist\u00eancia \u00e0 tra\u00e7\u00e3o. Algumas mangueiras de oxiacetileno podem ter uma tran\u00e7a de fio de a\u00e7o. No entanto, isso depende principalmente da flexibilidade e da resist\u00eancia da mangueira.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Outer_Cover\"><\/span>Capa exterior<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\r\n<p>O revestimento exterior da mangueira protege principalmente as duas camadas interiores contra danos externos. \u00c9 fabricado em borracha composta de SBR e EPDM. Como sabem, as borrachas SBR e EPDM s\u00e3o adequadas devido \u00e0 sua excelente resist\u00eancia \u00e0 abras\u00e3o. Estes dois materiais de borracha tamb\u00e9m se destacam pela resist\u00eancia \u00e0s intemp\u00e9ries e ao ozono. Consequentemente, nas mangueiras de oxiacetileno, estes materiais garantem seguran\u00e7a e durabilidade.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Surface\"><\/span>Superf\u00edcie<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\r\n<p>A camada final \u00e9 a camada superficial.

Algumas mangueiras podem apresentar uma superf\u00edcie estriada para maior durabilidade e facilidade de utiliza\u00e7\u00e3o.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Application_of_oxy-acetylene_hose\"><\/span>Utiliza\u00e7\u00e3o da mangueira de oxiacetileno<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\r\n<p>As mangueiras de oxi-acetileno s\u00e3o necess\u00e1rias em v\u00e1rias aplica\u00e7\u00f5es. No entanto, s\u00e3o frequentemente utilizadas sobretudo em processos de soldadura e corte.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\r\n<p>As mangueiras de soldadura com oxig\u00e9nio e acetileno desempenham um papel crucial no processo de soldadura. Estas mangueiras combinam oxig\u00e9nio e acetileno para produzir calor intenso, que normalmente ultrapassa o ponto de fus\u00e3o do metal. Este processo pode ser de grande ajuda na uni\u00e3o de duas pe\u00e7as met\u00e1licas. Por este motivo, costuma-se referir-se a este tipo de soldadura como \u00absoldadura a g\u00e1s\u00bb.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Na soldadura a laser, utilizam-se apenas gases inertes, enquanto na soldadura a arco se utiliza g\u00e1s \u00e1rgon. Por conseguinte, as mangueiras de soldadura variam consoante o tipo de soldadura.<\/p>\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Por outro lado, no corte, pode-se utilizar o mesmo princ\u00edpio para atravessar uma chapa met\u00e1lica. Quando estes gases se juntam, geram um calor intenso que derrete a chapa met\u00e1lica.
