1. Kev siv hluav taws xob ntau lawm ntawm lub zog- txuag PPR yeeb nkab tsuas yog 20 feem pua ntawm cov yeeb nkab steel, thiab nws cov thermal conductivity tsawg 0.2W / (mk), uas tsuas yog 1 / 200. ntawm cov yeeb nkab steel. Nws daim ntawv thov nyob rau hauv dej kub system yuav txo tau kub poob.
2. The use of PP-R pipe can avoid the "secondary pollution" of water quality caused by the scaling and rust of the inner wall caused by the use of galvanized steel pipe. Due to the simple component of PP-R, the basic components are carbon and hydrogen, which meet the food hygiene regulations and are non-toxic, so it is more suitable for the transportation of drinking water.
3. Nrog rau kev ua haujlwm kub, kev ua haujlwm siab thiab kev ua haujlwm ntev, qhov ntev -lub sijhawm kev pabcuam kub ntawm PP-R yeeb nkab tuaj yeem ncav cuag 95 degree thiab luv luv -lub sijhawm kev pabcuam kub tuaj yeem ncav cuag 120 degree. Thaum qhov kev pabcuam kub yog 70 degree thiab kev ua haujlwm siab yog 1.2MPa, nws tuaj yeem siv tsis tu ncua ntev, thiab lub neej kev pabcuam tuaj yeem ncav cuag ntau tshaj 50 xyoo.
4. Nrog lub teeb yuag, siab zog thiab tsis muaj dej tsis kam, qhov ntom ntawm PP -R yeeb nkab tsuas yog 1 / 8 ntawm cov yeeb nkab hlau. Lub siab ntsuas lub zog yog mus txog 5MPa, thiab nws muaj zog toughness thiab cuam tshuam tsis kam. Vim yog cov phab ntsa hauv du, tsis muaj xeb thiab scaling, cov dej tsis kam yog me me.
