IAPMO npe
IAPMO certifications fittings rau cov kav dej. Qhov no suav nrog kev siv dej haus.PEX compression fittingsnrog IAPMO kev pom zoo raug lees paub los ntawm cov neeg lis dej num.
Piv txwv li: kev tsim tsev tshiab
Tus neeg tsim khoom nruab PEX cov kav dej. Txhua qhov compression fittings yog NSF- ntawv pov thawj. Tus neeg soj ntsuam pom zoo rau lub installation.PEX compression fittingsua tau raws li tag nrho cov cai hauv tsev.
Piv txwv li: hloov lub rhaub dej
Tus kws kav dej hloov lub rhaub dej. Cov kev sib txuas siv tau ntawv pov thawj compression fittings. Tus tswv tsev tau txais cov dej haus nyab xeeb.PEX compression fittingstau pom zoo rau daim ntawv thov no.
Cov khoom siv hauv tsev fittings
Fittings siv lead ua -dawb DZR tooj dag . Cov tooj dag tsis muaj teeb meem additives. Cov stiffeners yog zaub mov- qib yas .PEX compression fittingsyog tsim los ntawm cov ntaub ntawv zoo.
Zam tsis txhob -tso cai fittings
Qee qhov pheej yig fittings tsis muaj NSF ntawv pov thawj. Cov no tej zaum yuav muaj cov hmoov lead lossis lwm yam kab mob. Tsis txhob siv cov khoom tsis muaj ntawv pov thawj rau cov dej haus.PEX compression fittingsyuav tsum yog NSF- ntawv pov thawj rau kev siv tau.
Cov kev xav tau ntawm kev xeem
Cov kav dej uas muaj peev xwm yuav tsum tau sim tom qab kev teeb tsa. Cov kab mob thiab kev ntsuas siab muaj ntau.PEX compression fittingsua tau zoo hauv cov kev sim no. Piv txwv: 100-psi siab ntsuas yog tus qauv.
Cov ntsiab lus pom zoo kawg
