L-interface tal-pajp PPR jadotta teknoloġija tat-tidwib sħun-, u l-pajpijiet huma kompletament integrati flimkien. Għalhekk, ladarba t-test tal-pressjoni tal-installazzjoni jgħaddi, ma jkun hemm l-ebda tnixxija tal-ilma, u l-affidabilità hija għolja ħafna. Madankollu, dan ma jfissirx li l-pajp ta 'l-ilma PPR huwa bla difetti, b'reżistenza fqira ta' temperatura għolja u reżistenza għall-pressjoni, u t-temperatura tax-xogħol fit-tul-ma tistax taqbeż is-70 grad; It-tul ta 'kull sezzjoni huwa limitat u ma jistax jitgħawweġ għall-kostruzzjoni. Jekk id-distanza tat-tqegħid tal-pipeline hija twila jew hemm ħafna kantunieri, numru kbir ta 'ġonot se jintużaw fil-kostruzzjoni; Il-pajpijiet huma irħas, iżda l-prezz tal-aċċessorji huwa relattivament għoli. F'termini ta 'prestazzjoni komprensiva, il-pajp PPR huwa l-pajp b'rendiment ta' spiża għolja fil-preżent, għalhekk sar il-materjal preferut għat-titjib tad-dar.
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.
