Com a <a href=\"https:\/\/delmas-tubes.com\/ca\/empresa\/\">especialistes en subministrament industrial<\/a>, en <a href=\"https:\/\/delmas-tubes.com\/ca\/\">Delm\u00e0s Tubes<\/a> abordem els aspectes metal\u00b7l\u00fargics, normatius i log\u00edstics que els enginyers i caps de compres han de valorar en especificar aquests components.<\/p>\n<h2>Processos de fabricaci\u00f3 i qualitats d'acer<\/h2>\n<p>Els conductes destinats a sistemes oleohidr\u00e0ulics es produeixen principalment mitjan\u00e7ant processos d'extrusi\u00f3 i laminaci\u00f3 en calent seguits d'estirat en fred. Aquest darrer pas \u00e9s fonamental, ja que l'estirat en fred confereix al material unes toler\u00e0ncies dimensionals estretes i un acabat superficial \u00f2ptim tant a l'interior com a l'exterior del tub.<\/p>\n<p>Per assegurar una resist\u00e8ncia mec\u00e0nica id\u00f2nia davant de pics de pressi\u00f3 i fatiga, els acers emprats solen complir amb normatives estrictes com la EN 10305-4 (tubs de precisi\u00f3 sense soldadura per a sistemes hidr\u00e0ulics i pneum\u00e0tics). Depenent dels requeriments de flexi\u00f3 i pressi\u00f3 de treball, se seleccionen acers al carboni espec\u00edfics amb tractaments t\u00e8rmics de normalitzat (+N), que garanteixen l'abs\u00e8ncia de tensions residuals i faciliten les operacions posteriors de corbat i abocardat.<\/p>\n<h2>Especificacions t\u00e8cniques i normatives aplicables<\/h2>\n<p>L'especificaci\u00f3 d'un tub hidr\u00e0ulic no es limita al di\u00e0metre exterior (DE) i al gruix de paret. Cal calcular la pressi\u00f3 de servei i la pressi\u00f3 de trencament aplicant els factors de seguretat exigits per les normatives europees i internacionals.

destinats a sistemes hidr\u00e0ulics i pneum\u00e0tics.<\/p>\n<h3>Per qu\u00e8 \u00e9s important el tractament t\u00e8rmic +N en aquests tubs?<\/h3>\n<p>L'estat de subministrament +N (normalitzat) assegura que l'acer ha patit un tractament t\u00e8rmic que homogenitza l'estructura del gra, eliminant tensions internes i millorant la capacitat de deformaci\u00f3 per a processos de doblegat.<\/p>\n<h3>Com es garanteix la neteja a l'interior dels tubs hidr\u00e0ulics?<\/h3>\n<p>Els tubs de qualitat hidr\u00e0ulica se sotmeten a processos de bufat, rentat i obturaci\u00f3 als
