Är PE-rör rädda för att frysa?

2025-08-19

Under den kalla vintern är röret frostskyddsmedel i fokus för många människors uppmärksamhet, särskilt i vattenförsörjning, uppvärmning och andra system som ofta används i PE-rör, om det är rädd för frysning har blivit en fråga för många användare. PE-rör är polyetenrör, som har fördelarna med låg vikt, korrosionsbeständighet, bekväm konstruktion, etc., men hur är dess frostskyddsmedel?

PE-röret själv har en viss grad av flexibilitet. I låg temperaturmiljö kommer dess material inte att vara lika lätt att bryta som spröda material. Huruvida PE-röret kommer att frysa beror dock främst på tillståndet för mediet i röret. När vattnet i röret fryser kommer volymen att expandera och generera enormt tryck. Om väggtjockleken på PE-röret är otillräcklig, felaktig installation eller i en extremt låg temperaturmiljö kan detta tryck orsaka att röret går sönder. Därför är PE-rör inte absolut inte rädd för frysning. Dess frostbeständighet är nära relaterad till kvaliteten på röret, installationsprocessen och användningsmiljön.

Som ett välkänt varumärke i branschen uppmärksammar AD Pipe alltid produktkvalitet och prestandaförbättring vid produktion av PE-rör. AD PE-rör är tillverkat av högkvalitativa polyetenråvaror och tillverkas genom avancerad produktionsteknik för att säkerställa att röret har god flexibilitet och slaghållfasthet. Under låga temperaturförhållanden kan AD PE-rör motstå trycket som orsakas av vattenfrysning och expansion i viss utsträckning, vilket minskar risken för frysning och sprickbildning. Samtidigt tillhandahåller AD Pipe en mängd olika specifikationer och väggtjocklek PE-rörprodukter enligt olika användningsscenarier för att möta frysskyddsbehoven i olika miljöer.

För att ytterligare säkerställa en säker användning av PE-rör på vintern, förutom att välja högkvalitativa AD PE-rörprodukter, måste lämpliga skyddsåtgärder vidtas. Till exempel, vid läggning av rör, bör en rimlig begravningsdjupdesign utföras enligt den lokala minimitemperaturen för att undvika att rörledningen exponeras ovanför det frysta jordskiktet; för utomhusmonterade PE-rör, värmeisolering bomull, värmeisoleringshölje etc. kan användas för att linda för att minska värmeförlusten; innan vintern kommer, dränera det ackumulerade vattnet i rörledningen i tid för att förhindra frysning och expansion.

Kort sagt, PE-rör kan ha god frostbeständighet under förutsättning av rimlig installation och underhåll. Att välja PE-rörprodukter med tillförlitlig kvalitet som AD-rör, i kombination med vetenskapliga åtgärder mot frysning, kan effektivt minska risken för frysskador i vinterrör och säkerställa en stabil drift av vattenförsörjning, värme och andra system. I praktiska tillämpningar måste användarna också konsultera yrkesverksamma enligt den specifika miljön och användningsbehov för att formulera en perfekt rörledning och skyddsplan.
