PPR pipesalso known aspolypropylenetube,put it plainlyiswethe peoplehomelifeforwater reform,an important materialoftheheating system.Towaterways,heatingthesecovertprojectsdo not stay hidden, selecthigh-qualityPPR pipesisparticularly important, thenhow to distinguishthequalityofPPR pipes?
1) Firsttouchthesurfaceofthepipebyhand, to experience thetextureisdelicate,theparticlesis uniform.On the market today,PPR pipesmainlywhite, gray,greenin several colors,under normal circumstances,recycled plasticcan not make awhite, so many peopletend to believe thatwhiteis the best, in fact,this viewisone-sided.Astechnology improved, thecolor is notto identifythequality standardsofPPR pipes.
