Karakteristik Design
1. Li gen bon fleksibilite, ki fè li pratik ak ékonomi mete. Tiyo ki pwodui yo ka mawonnen ak koube pandan konstriksyon pou diminye itilizasyon ekipman tiyo yo epi redwi depans konstriksyon yo.
2. Ba tanperati krak frajil. Tiyo a gen ekselan rezistans tanperati ki ba -, kidonk li kapab tou konstwi nan ka tanperati ki ba nan sezon fredi, epi tiyo a pa bezwen prechofe lè koube.
3. Bon rezistans chimik ak lavi sèvis long;
4. Bon adaptabilite nan anviwònman an, lejè, bon fleksibilite, epi yo ka apwovizyone nan bobin;
5. Anba kondisyon ke tanperati travay la se 70 degre Sèlsiyis ak presyon an se 0.4MPa, li ka itilize san danje pou plis pase 50 ane.
6. Pa gen aditif toksik yo ajoute nan tiyo a pandan pwosesis pwodiksyon an. Miray enteryè a lis, li pa -echèl, epi li pa elve bakteri, ki ka itilize san danje nan transpò dlo pou bwè ak lòt jaden.
Dimansyon aplikasyon
The application of PE-RT pipes in the field of cold and hot water pipes in buildings in my country has developed rapidly, and the raw materials have also further developed. In 2002, the industry-standard "heat-resistant polyethylene (PE-RT) piping system for hot and cold water" was released, but because the industry standard at that time was based on the German standard "heat-resistant polyethylene (PE-RT) piping - general quality requirements" " and "Heat Resistant Polyethylene (PE-RT) Pipes - Dimensions", both of which are based on the performance indicators of Type I PE-RT materials. With the development of materials, the performance indicators of type II PE-RT materials have been much higher than the first-generation materials, and the international standard ISO22391 "heat-resistant polyethylene (PE-RT) piping system for cold and hot water" has also been revised and updated. , adding requirements for Type II PE-RT piping. 1
Avèk devlopman materyèl yo, tiyo PE-RT yo te mete ajou ak amelyore nan tiyo PE-RT II, ki divize an twa kalite dapre comonomè yo:
1. Ethylene ak oktèn copolymerization - chalè - polyethylene rezistan (C2 plis C8);
2. Ethylene ak hexene copolymerization -chalè - polyethylene rezistan (C2 plis C6);
3. Polyethylene ki reziste chalè - (C2 plis C4) copolymerized ak etilèn ak butèn
The launched (PE-RT Ⅱ type pipe) material is suitable for industrial and civil building cold and hot water pipeline systems, drinking water systems, thermal embedded pipes, ground radiant heating systems, and high-temperature ground source heat pump systems, especially in northern applications. In the secondary pipe network of urban heating system - PE-RT II type prefabricated direct buried thermal insulation pipe.
