Sa dilatation thermique plus faible peut \u00eatre utile sur de longs parcours de circulation o\u00f9 la limitation des mouvements du tuyau est importante.

Entre les p\u00e9riodes d'utilisation, une branche d'eau chaude ordinaire peut refroidir, mais une boucle de recirculation maintient l'eau chaude en mouvement. Par cons\u00e9quent, une grande partie de la tuyauterie de retour peut rester sous pression et chaude pendant de longues p\u00e9riodes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cela change la fa\u00e7on dont vous s\u00e9lectionnez un tuyau PPR pour l'alimentation en eau chaude. Dans les applications de circulation d'eau chaude avec tuyau PPR, le tuyau doit convenir aux conditions \u00e0 long terme du syst\u00e8me plut\u00f4t que de simplement tol\u00e9rer l'utilisation d'eau chaude.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Three_Challenges_Do_Hot_Water_Circulation_Systems_Pose_for_Piping_Materials\"><\/span><strong>Quels sont les trois d\u00e9fis que les syst\u00e8mes de circulation d'eau chaude posent aux mat\u00e9riaux de tuyauterie ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">La circulation d'eau chaude expose le tuyau \u00e0 la chaleur et \u00e0 la pression pendant des p\u00e9riodes beaucoup plus longues qu'une conduite qui refroidit entre les utilisations. Cependant, vous devez consid\u00e9rer \u00e0 la fois la pression et la temp\u00e9rature de fonctionnement ensemble au lieu de vous fier uniquement \u00e0 la classification PN. C'est parce qu'une augmentation de la temp\u00e9rature modifie la pression admissible du polypropyl\u00e8ne.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vous devez \u00e9galement tenir compte du flux continu. La vitesse de l'eau et le diam\u00e8tre du tuyau doivent convenir \u00e0 un syst\u00e8me o\u00f9 l'eau peut circuler pendant de longues p\u00e9riodes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il est alors essentiel de tenir compte du mouvement thermique, en particulier sur les conduites de retour et les longs couloirs. Le tuyau se dilate sur sa longueur \u00e0 mesure qu'il chauffe, le syst\u00e8me a donc besoin de suffisamment d'espace et de support pour accommoder cette dilatation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Alors, peut <a href=\"https:\/\/www.desopipe.com\/fr\/product\/ppr-pipe\/\" target=\"_blank\" rel=\"noreferrer noopener\">Tuyau PPR<\/a> \u00eatre utilis\u00e9 pour la circulation d'eau chaude ? Oui, mais la s\u00e9rie de tuyaux, les conditions de fonctionnement et la disposition doivent toutes convenir \u00e0 une circulation continue plut\u00f4t qu'\u00e0 une utilisation occasionnelle d'eau chaude.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Does_Aluminum_Reinforcement_Help_on_a_Hot_Water_Circulation_Loop\"><\/span><strong>Comment le renforcement en aluminium aide-t-il sur une boucle de circulation d'eau chaude ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Consid\u00e9rez une longue conduite de retour qui reste chaude toute la journ\u00e9e. Chaque m\u00e8tre contribue au changement total de la longueur du tuyau \u00e0 mesure que la temp\u00e9rature augmente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ce mouvement est plus limit\u00e9 avec un tuyau PPR avec aluminium. Le <a href=\"https:\/\/www.desopipe.com\/fr\/ppr-pipe-for-hvac-heating\/\" target=\"_blank\" rel=\"noreferrer noopener\">guide de tuyauterie PPR de DESO pour CVC et chauffage<\/a> donne un coefficient de dilatation lin\u00e9aire d'environ 0,050 mm\/m\u00b7K pour le PPR-AL-PPR, contre environ 0,150 mm\/m\u00b7K pour le <a href=\"https:\/\/www.desopipe.com\/fr\/product\/standard-ppr-pipe\/\" target=\"_blank\" rel=\"noreferrer noopener\">PP-R standard<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cette dilatation plus faible laisse moins de mouvement \u00e0 la disposition de la tuyauterie pour s'adapter sur de longs parcours expos\u00e9s et des colonnes montantes. L\u00e0 o\u00f9 le maintien de l'alignement est la priorit\u00e9 principale, cela peut \u00eatre particuli\u00e8rement utile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gardez \u00e0 l'esprit qu'un certain mouvement subsistera. Ainsi, tous les points fixes, guides et autres types de compensation requis doivent convenir au diam\u00e8tre du tuyau et \u00e0 la disposition.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Do_Aluminum_Composite_PPR_Standard_PPR_and_PEX_Behave_in_a_Circulation_Loop\"><\/span><strong>Comment le PPR composite aluminium, le PPR standard et le PEX se comportent-ils dans une boucle de circulation ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le PPR standard peut servir de tuyau PPR pour eau chaude lorsqu'il est correctement sp\u00e9cifi\u00e9. Sa dilatation thermique plus \u00e9lev\u00e9e laisse cependant plus de mouvement \u00e0 accommoder sur de longs parcours.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Un tuyau composite aluminium apporte une plus grande rigidit\u00e9 et une dilatation plus faible. Cela peut le rendre utile pour les parcours rectilignes, les colonnes montantes ou les tuyauteries visibles o\u00f9 un contr\u00f4le dimensionnel plus strict est pr\u00e9f\u00e9r\u00e9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.desopipe.com\/fr\/blog\/ppr-pipe\/ppr-pipe-vs-pex\/\" target=\"_blank\" rel=\"noreferrer noopener\">PEX<\/a> se comporte diff\u00e9remment en raison de sa flexibilit\u00e9. Il peut \u00eatre achemin\u00e9 plus facilement autour des obstacles, tandis que son comportement de dilatation, ses besoins de support et ses m\u00e9thodes de jonction n\u00e9cessitent une approche d'installation diff\u00e9rente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pour la circulation d'eau chaude en PPR composite aluminium, la r\u00e9duction du mouvement devient la plus utile lorsque la disposition en b\u00e9n\u00e9ficie r\u00e9ellement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Should_Installers_Check_Before_Using_Aluminum_Composite_PPR\"><\/span><strong>Que doivent v\u00e9rifier les installateurs avant d'utiliser le PPR composite aluminium ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Les exigences de la construction sp\u00e9cifique du tuyau sont le point de d\u00e9part d'une installation correcte. En fonction de la conception du tuyau composite aluminium, une pr\u00e9paration suppl\u00e9mentaire des extr\u00e9mit\u00e9s peut \u00eatre n\u00e9cessaire avant <a href=\"https:\/\/www.desopipe.com\/fr\/blog\/ppr-pipe\/ppr-pipe-welding-hot-fusion-guide\/\" target=\"_blank\" rel=\"noreferrer noopener\">fusion thermique<\/a>. Assurez-vous de suivre la proc\u00e9dure d'installation sp\u00e9cifi\u00e9e pour le syst\u00e8me de tuyauterie plut\u00f4t que de mettre en \u0153uvre la m\u00eame proc\u00e9dure pour chaque tuyau composite.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La planification de la dilatation et le support sont \u00e9galement essentiels. Bien que le mouvement thermique soit r\u00e9duit avec le renforcement en aluminium, il n'est pas enti\u00e8rement \u00e9limin\u00e9. La longueur du parcours, la temp\u00e9rature de fonctionnement, la disposition et le diam\u00e8tre de la tuyauterie affectent tous la mani\u00e8re dont la tuyauterie doit \u00eatre support\u00e9e et autoris\u00e9e \u00e0 bouger.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pour la circulation d'eau chaude, les installateurs doivent \u00e9galement confirmer que la s\u00e9rie de tuyaux s\u00e9lectionn\u00e9e convient \u00e0 la temp\u00e9rature et \u00e0 la pression \u00e0 long terme du syst\u00e8me.

Commencez par la temp\u00e9rature, la pression, les dimensions et la disposition de la boucle, puis s\u00e9lectionnez la construction en fonction de ces exigences.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"FAQs\"><\/span><strong>FAQ<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Can_you_use_aluminum-layered_PPR_pipes_for_hot_water_lines\"><\/span><strong>Peut-on utiliser des tuyaux PPR \u00e0 couches d'aluminium pour les conduites d'eau chaude ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Oui, mais assurez-vous que la s\u00e9rie de tuyaux choisie est capable de g\u00e9rer la pression et la temp\u00e9rature de l'eau de la conduite d'eau chaude pendant sa dur\u00e9e de vie pr\u00e9vue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_What_is_the_maximum_temperature_for_PPR_aluminum_composite_pipe\"><\/span><strong>Quelle est la temp\u00e9rature maximale pour un tuyau PPR composite aluminium ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Le tuyau PPR composite aluminium de DESO a une plage de temp\u00e9rature indiqu\u00e9e atteignant 95\u00b0C. Cependant, 95\u00b0C n'est pas destin\u00e9 \u00e0 \u00eatre une temp\u00e9rature de fonctionnement continue. Pour un service \u00e0 long terme, notre guide CVC utilise 70\u00b0C comme temp\u00e9rature de r\u00e9f\u00e9rence.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Will_the_pipe_bend_or_lose_its_shape_in_hot_water\"><\/span><strong>Le tuyau se pliera-t-il ou perdra-t-il sa forme dans l'eau chaude ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Le PPR se dilate \u00e0 mesure que sa temp\u00e9rature augmente. La couche d'aluminium r\u00e9duit ce mouvement par rapport au PPR standard, aidant le tuyau \u00e0 maintenir son alignement lorsque les temp\u00e9ratures changent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Is_regular_PPR_pipe_good_for_hot_water\"><\/span><strong>Le tuyau PPR ordinaire est-il bon pour l'eau chaude ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Oui. Le PPR ordinaire peut g\u00e9rer l'eau chaude tant que la s\u00e9rie de tuyaux que vous choisissez est correcte pour la pression et la temp\u00e9rature de fonctionnement du syst\u00e8me.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Which_pipe_is_actually_the_best_for_hot_water_loops\"><\/span><strong>Quel tuyau est r\u00e9ellement le meilleur pour les boucles d'eau chaude ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Il n'y a pas un seul choix pour chaque syst\u00e8me. Le PPR composite aluminium peut \u00eatre utile lorsque le contr\u00f4le de la dilatation est important. Pendant ce temps, les configurations moins exigeantes peuvent ne n\u00e9cessiter que du PPR standard.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_What_is_the_difference_between_aluminum_PPR_and_PEX_pipes\"><\/span><strong>Quelle est la diff\u00e9rence entre les tuyaux PPR aluminium et PEX ?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La principale diff\u00e9rence entre ces deux types de tuyaux est la flexibilit\u00e9. Le PPR composite aluminium est un syst\u00e8me de tuyauterie rigide, tandis que le PEX peut se plier autour des coins et des obstacles plus facilement.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-white-color has-text-color has-background has-link-color wp-element-button\" href=\"https:\/\/www.desopipe.com\/fr\/contact\/\" style=\"background-color:#0588a7\" target=\"_blank\" rel=\"noreferrer noopener\">Obtenez un devis gratuit<\/a><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Quick answer Aluminum composite PPR can suit hot water circulation when its pipe series matches the loop\u2019s long-term temperature and pressure.
