Ngaphambi kokufaka imininingwane, ake siqale sithole ukuthi into ngayinye yenziwe ngani. I-PPR isifinyezo se-polypropylene random copolymer, kanti i-CPVC iyi-chlorined polyvinyl chloride ekhiqizwa ngenqubo ye-chlorination ibe yi-polyvinyl chloride.
I-PPR uhlelo lwamapayipi olusetshenziswa kakhulu eYurophu, eRussia, eNingizimu Melika, e-Afrika, eNingizimu Asia, eShayina naseMpumalanga Ephakathi, kuyilaphoI-CPVCisetshenziswa kakhulu eNdiya naseMexico. I-PPR ingcono kune-CPVC hhayi ngenxa yokwamukelwa kwayo kabanzi, futhi iphephile emanzini okuphuza.
Manje, ake sikusize wenze isinqumo esiphephile, uqonde ukuthi kungani ukufaka amapayipi e-CPVC kungaphephile nokuthi kungani kufanele ukhetheAmapayipi e-PPR.

Ipulasitiki yezinga lokudla:
Amapayipi e-PPR awaqukethe izinto ezisuselwa ku-chlorine futhi aphephile emzimbeni womuntu, kuyilapho isakhiwo sepayipi le-CPVC siqukethe i-chlorine, engahlukaniswa futhi incibilikiswe emanzini ngesimo se-vinyl chloride bese iqongelela emzimbeni womuntu.
Kwezinye izimo, ukuvuza kutholakale endabeni yamapayipi e-CPVC ngoba anokunamathela okubuthakathaka futhi adinga izinyibilikisi zamakhemikhali, kuyilapho amapayipi e-PPR ehlanganiswa ngokuhlanganiswa kokushisa futhi avimbele amapayipi amakhulu nokunamathela okuqinile. Amandla ahlangene aholela kunoma yiluphi uhlobo lokuvuza. I-United States yenze izifundo eziningi ngokuvuza kwezinto eziyingozi njenge-chloroform, i-tetrahydrofuran kanye ne-acetate emanzini okuphuza ngokusebenzisaAmapayipi e-CPVC.

Izinyibilikisi ezisetshenziswa ku-CPVC zibeka impilo yakho engozini:

I-California Pipeline Trade Commission inesibopho sokubuyekeza imiphumela yezempilo yezinhlelo zamapayipi futhi iyi-ejensi yokuqinisekisa amapayipi eCalifornia, e-USA. Ihlale ikhuthaza kakhulu imiphumela eyingozi yezinyibilikisi ezisetshenziswa ukuxhuma amapayipi e-CPVC. Kutholakale ukuthi isinyibilikisi siqukethe izakhi ezibangela umdlavuza ezilwaneni futhi sibhekwa njengesingaba yingozi kubantu. Ngakolunye uhlangothi, amapayipi e-PPR awadingi izinyibilikisi futhi axhunywe ngobuchwepheshe bokuncibilikisa ukushisa, ngakho-ke awaqukethe amakhemikhali anobuthi.

Ipayipi le-PPR liyimpendulo enempilo:
Amapayipi e-KPT PPR enziwe ngezinto zokusetshenziswa ezisezingeni eliphezulu, ezisezingeni lokudla, eziguquguqukayo, eziqinile, futhi angamelana nokushisa okusukela ku--10°C kuya ku-95°C. Amapayipi e-KPT PPR anempilo yenkonzo ende kakhulu, engasetshenziswa iminyaka engaphezu kwengu-50.
