1. PPR kav thiab fittings nrog mos zoo nkauj yuav tsis yooj yim deform vim extrusion. Txawm hais tias lawv deformed, lawv yuav tsis tawg, thiab ntau cov pob qij txha siv tsis tau.
2. Cov khoom siv tshuaj lom neeg ntawm PPR yeeb nkab uas tsis yooj yim rau corrode thiab tsim cov nplai tuaj yeem zam qhov kev yaig ntawm cov tshuaj lom neeg hauv dej, thiab qhov chaw ntawm cov yeeb nkab no yog tus du thiab yuav tsis tsim cov nplai.
3. PPR cov kav dej uas tuaj yeem siv rau hauv siab - qhov kub thiab txias - qhov chaw siab tuaj yeem siv rau hauv qab dej siab ntawm 45 kg ib square meter ntawm qhov kub thiab txias, thiab cov kav dej yuav tsis deform hauv qab 112. qib.
4. PPR raj uas tau siv rau lub sijhawm ntev tuaj yeem tiv thaiv kev laus. Feem ntau, lawv tuaj yeem siv rau ntau tshaj 50 xyoo.
5. PPR yeeb nkab muaj qhov ua tau zoo, thiab kev tsim kho kuj yooj yim heev thiab ceev, thiab kev sib txuas kuj yooj yim heev thiab nyab xeeb.
6. Vim tias kev tsim kho tsis muaj teeb meem ntau, nws yuav tsis cuam tshuam rau lwm yam haujlwm, thiab lub sijhawm tsim kho yuav tsis ntev. Cov nyiaj siv yog ntau tshaj li ib nrab ntawm cov yeeb nkab tooj liab, uas yog kev lag luam heev.
