Lub interface ntawm PPR yeeb nkab txais cov khoom kub-kua tshuab, thiab cov kav dej tau ua tiav ua ke. Yog li ntawd, thaum lub installation siab dhau lawm, yuav tsis muaj dej to, thiab kev ntseeg siab yog siab heev. Txawm li cas los xij, qhov no tsis txhais tau hais tias PPR cov kav dej tsis muaj qhov tsis zoo, nrog rau qhov tsis zoo ntawm qhov kub thiab txias tsis kam, thiab qhov ntev -lub sijhawm ua haujlwm kub tsis tuaj yeem tshaj 70 degree ; Qhov ntev ntawm txhua ntu yog txwv thiab tsis tuaj yeem khoov rau kev tsim kho. Yog hais tias lub raj xa dej tso qhov nrug ntev ntev los yog muaj ntau lub ces kaum, ntau cov pob qij txha yuav siv rau hauv kev tsim kho; Cov kav dej yog pheej yig, tab sis tus nqi ntawm cov khoom siv kuj yog siab heev. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, PPR yeeb nkab yog cov yeeb nkab nrog cov nqi siab ntawm kev ua haujlwm tam sim no, yog li nws tau dhau los ua cov khoom siv rau kev txhim kho tsev.
PPR pipes sold on the market mainly have two colors, white and gray. Why is this difference? The dealer's answer is caused by the different PPR particles of raw materials used. Due to the inconsistency of thermal expansion coefficient and expansion force between PPR pipe and metal elbow clamp, in the process of long-term thermal expansion and cold contraction friction, coupled with the external tension of the pipe itself, it intensifies the depth of scratches, resulting in water leakage of floor heating pipe, burying serious hidden dangers for the safety of floor heating system and increasing the service life of floor heating: installing pipe with plastic elbow clamp can effectively avoid scratches and Whitening, facts have proved that the cost of using plastic elbow card is far lower than the cost of repairing pipe scratches and whitening; The safety and reliability of floor heating pipes are improved, so as to increase the service life of floor heating.
