Può il tubo PPR ferro ferro ferro PE tubo?

2025-08-19

Nella costruzione di condutture, si incontrano spesso vari problemi di connessione, tra i quali "se la macchina da stiro per tubi PPR può stirare il tubo PE" è un argomento di grande preoccupazione. Alcuni operai edili potrebbero pensare che siano tutti tubi di plastica e che gli strumenti hot melt possano essere universali, ma la verità non è il caso. Il tubo

PPR e il tubo PE sono entrambi tubi di plastica, ma le loro caratteristiche materiali e i requisiti hot melt sono significativamente diversi. Il componente principale del tubo PPR è il polipropilene copolimero casuale e la sua temperatura hot melt è solitamente di circa 260 ° C. Il componente principale del tubo PE è il polietilene. In base alla densità e ad altri modelli, la sua temperatura hot melt è generalmente compresa tra 180 ° C e 220 ° C. La macchina da stiro per tubi PPR

PPR è appositamente progettata per il tubo PPR e la sua temperatura predefinita hot melt è impostata per il tubo. Se si utilizza un ferro per tubi PPR per stirare il tubo PE, poiché la temperatura del ferro per tubi PPR è molto più alta della temperatura hot melt richiesta per il tubo PE, causerà il surriscaldamento del tubo PE. Il tubo PE surriscaldato avrà problemi come eccessiva fusione, assottigliamento della parete del tubo e persino carbonizzazione, che non solo distruggerà la resistenza strutturale del tubo, ma influenzerà anche la tenuta della connessione, che può facilmente causare rischi per la sicurezza come perdite d'acqua nell'uso successivo.

Al contrario, se si utilizza una macchina hot melt per tubo PE per stirare il tubo PPR, a causa della temperatura insufficiente, il tubo PPR non può raggiungere lo stato fuso ideale, il che porterà anche a una connessione debole. Pertanto, il collegamento hot melt del tubo PPR e del tubo PE deve utilizzare i propri speciali strumenti hot melt e seguire rigorosamente la temperatura hot melt e le procedure operative specificate.

Al fine di garantire la sicurezza e l'affidabilità del sistema di tubazioni, dobbiamo prestare attenzione alla corretta selezione e utilizzo degli strumenti di costruzione. Quando si acquista e si utilizza una macchina hot melt, prestare attenzione a distinguere tra modelli speciali PPR e PE e scegliere lo stampo corrispondente in base alle specifiche del tubo. I marchi professionali come AD Pipeline di solito hanno linee guida di costruzione dettagliate allegate ai loro prodotti. Si consiglia al personale di costruzione di leggerlo attentamente prima dell'operazione o di consultare tecnici professionisti per garantire che ogni punto di connessione soddisfi gli standard e garantisca il funzionamento stabile a lungo termine dell'intero sistema di tubazioni.

In breve, le macchine da stiro per tubi PPR non possono essere utilizzate per stirare i tubi in PE. La temperatura hot melt richiesta varia notevolmente a causa dei diversi materiali e gli strumenti misti influiranno seriamente sulla qualità della connessione. Scegli gli strumenti giusti e segui i passaggi di costruzione standardizzati per creare un sistema di tubazioni sicuro e durevole.
