ppr供水管材，是一種以ppr為原料的，加工制作的供水管。ppr原料具有健康、衛生、等的特點，是一種材料。隨著社會的發展，pvc管業廠家，人們對于環境保護的重視，ppr原料已成為upvc給水管、鋁塑管、pe管、pex管、pert管的更新換代產品，一躍成為當代家裝建材管道行業的---兒。
ppr water supply pipe is a kind of water supply pipe made from ppr. ppr is a kind of environmental protection material with the characteristics of health， sanitation&environmental protection. with the development of society&peoples attention to environmental protection， ppr raw material has become a new product of upvc water supply pipe， aluminum plastic pipe， pe pipe， pex pipe&pert pipe，&has become a new favorite of the contemporary home decoration building materials pipeline industry.
ppr管施工后須經試壓驗收后方能封管和使用。ppr管安裝主要采用熱熔管件，熔接時間和壓力不好掌握，工藝隨機性較大，在熱熔推接過程中易產生堆料從而減小通徑，并使熔接處成為不規則的缺陷區，產生應力集中，影響ppr管價格的長期性能；對于ppr管的電熔連接，pvc管業電話，由于電熔絲主要采用促進ppr降解的銅，會加速ppr管的老化。
ppr pipe can be sealed&used only after pressure test&acceptance.the ppr pipe is mainly installed with hot-melt pipe fittings. the welding time&pressure are not well mastered，&the process is random. in the process of hot melt push welding， it is easy to generate stacking materials to reduce the diameter，&make the fusion joint become an irregular defect area， which produces stress concentration， which affects the long-term energy of price of ppr pipe; for the electric melting connection of ppr pipe， the aging of ppr pipe will be accelerated because copper is mainly used to promote the degradation of ppr.
