Kan PPR-röret järn järn järn PE-rör?

2025-08-19

I rörledningskonstruktion påträffas ofta olika anslutningsproblem, bland vilka "huruvida PPR-rörstrykningsmaskinen kan stryka PE-röret" är ett ämne som är mycket bekymrat. Vissa byggnadsarbetare kan tro att de alla är plaströr, och smältverktyg kan vara universella, men sanningen är inte fallet.

PPR-rör och PE-rör är båda plaströr, men deras materialegenskaper och smältkrav är väsentligt olika. Huvudkomponenten i PPR-rör är slumpmässig sampolymer polypropen, och dess smälttemperatur är vanligtvis runt 260 ° C. Huvudkomponenten i PE-rör är polyeten. Enligt densiteten och andra modeller är dess smälttemperatur i allmänhet mellan 180 ° C och 220 ° C.

PPR-rörstrykningsmaskin är speciellt utformad för PPR-rör, och dess standard smälttemperatur är inställd enligt egenskaperna hos PPR-rör. Om du använder ett PPR-rörjärn för att stryka PE-röret, eftersom temperaturen på PPR-rörjärnet är mycket högre än den heta smälttemperaturen som krävs för PE-röret, kommer det att leda till att PE-röret blir överhettat. Överhettat PE-rör kommer att ha problem som överdriven smältning, gallring av rörväggen och till och med karbonisering, vilket inte bara förstör rörets strukturella hållfasthet utan också påverkar tätningen av anslutningen, vilket lätt kan orsaka säkerhetsrisker som vattenläckage vid senare användning.

Tvärtom, om du använder en smältmaskin för PE-rör för att stryka PPR-röret, på grund av otillräcklig temperatur, kan PPR-röret inte nå det ideala smälta tillståndet, vilket också leder till svag anslutning. Därför måste varmsmältningsanslutningen av PPR-rör och PE-rör använda sina egna speciella smältverktyg och strikt följa deras angivna smälttemperatur och driftsförfaranden.

För att säkerställa säkerheten och tillförlitligheten hos rörledningssystemet måste vi vara uppmärksamma på rätt val och användning av byggverktyg. När du köper och använder en smältmaskin, var uppmärksam på att skilja mellan PPR och PE-specialmodeller och välj matchande matris enligt rörspecifikationerna. Professionella märken som AD Pipeline har vanligtvis detaljerade konstruktionsriktlinjer kopplade till sina produkter. Det rekommenderas att byggpersonal läser det noggrant före drift, eller konsulterar professionella tekniker för att säkerställa att varje anslutningspunkt uppfyller standarderna och säkerställer en långsiktig stabil drift av hela rörledningssystemet.

Kort sagt, PPR-rörstrykningsmaskiner kan inte användas för att stryka PE-rör. Den erforderliga smälttemperaturen varierar kraftigt på grund av olika material, och blandade verktyg kommer allvarligt att påverka anslutningskvaliteten. Välj rätt verktyg och följ de standardiserade konstruktionsstegen för att skapa ett säkert och hållbart rörledningssystem.
