Ezimbonini zesimanje zokwakha nezokufakwa kwamapayipi, ukukhetha izinto ezifanele zamapayipi kubalulekile ukuqinisekisa ukuqina, ukusebenza kahle, nokuphepha ezinhlelweni zokuhambisa amanzi nokudonsa. Phakathi kwezinketho ezithandwa kakhulu kukhona amapayipi e-PEX, e-PPR, kanye ne-PVC, ngalinye linobuntu obuhlukile bezinto kanye nezinzuzo zokusebenzisa. Lesi sihloko sinikeza ukuqhathanisa okuphelele kwezinhlobo ezintathu zamapayipi, sichaza izici zawo, izimfanelo zokusebenza, kanye nokusetshenziswa okuvamile. Ngokuqonda umehluko, amabhizinisi kanye nochwepheshe bangenza izinqumo ezinolwazi ezihambisana nezidingo ezithile zamaphrojekthi abo.

Amapayipi e-PEX, noma amapayipi e-polyethylene axhunyiwe, ahlukaniswa ngokwakhiwa kwawo okusha kwama-molecule okwenza inethiwekhi enezinhlangothi ezintathu ezintweni ze-polyethylene. Lokhu kuxhunywa kuthuthukisa uqine nokubuyela emuva kwamapayipi, okunikeza ukumelana okuphezulu ezimweni ezishisayo nezibandayo. Amapayipi e-PEX abonisa ukuguquguquka okuhle kakhulu, okuvumela ukugoba kalula nokunciphisa isidingo sezinto eziningi zokuxhuma ngesikhathi sokufakwa. Izimfanelo ezinjalo azigcini nje ngokwenza lula umsebenzi wokufaka amapayipi kodwa futhi zinciphisa izindawo ezingasevuza.

Ezinye zezinzuzo eziyinhloko zamapayipi e-PEX zitholakala ezindleleni zawo zokuxhuma ezithuthukisiwe njengokucindezela, ukubopha, noma izixhumi ezicindezelayo, ezisheshisa ukufakwa futhi zinciphise izindleko zabasebenzi. Amandla abo okubekezelela izinga lokushisa eliphezulu nezimo zokuqhwa kwenza zibe zilungele izinhlelo zokuhlinzekwa kwamanzi ashisayo abandayo endlini, kanye nezicelo zokufudumeza phansi. Ngaphezu kwalokho, ingaphezulu langaphakathi elibushelelezi lamapayipi e-PEX liqinisekisa ukulahlekelwa okuncane kokungqubuzana, okufaka isandla ekuhambeni kahle kwamanzi nasekwinciphisweni kokusetshenziswa kwamandla.

Ngenxa yalezi zinzuzo zokusebenza, izinhlelo zamapayipi e-PEX zamukelwa kabanzi ezakhiweni zokuhlala nezamabhizinisi ezixazululweni zamapayipi okudonsa amanzi nokushisisa. Ukuguquguquka nokuqina kwamapayipi e-PEX kunikeza ukwethembeka kwesikhathi eside, okwenza kube ukukhetha okudumile kuzo zombili izakhiwo ezintsha kanye namaphrojekthi wokulungisa.

Amapayipi e-PPR, noma amapayipi e-polypropylene copolymer angahleliwe, enziwa kusuka ku-polymer ye-thermoplastic eyaziwa ngokuqina kwayo nokumelana nokugqwala kwamakhemikhali. Izindonga zangaphakathi zamapayipi e-PPR zimnene futhi zibonisa izici ezinhle kakhulu zokuvikela ukushisa, okusiza ukugcina izinga lokushisa lamanzi nokuvimbela ukulahleka kokushisa. Lokhu kwenza i-PPR ukukhetha okusebenzayo kwezinto ezinhlelweni zamapayipi amanzi ashisayo abandayo.

Lezi zishimula zibonisa ukumelana nezinga lokushisa eliphezulu, zikwazi ukumelana nezinga lokushisa elifika ku-95°C, okwenza zilungele imigqa yokuhambisa amanzi ashisayo. Kodwa-ke, izishimula ze-PPR zingaba brittle emazingeni okushisa aphansi kakhulu, okudinga ukucatshangelwa ngokucophelela ezindaweni ezibandayo. Ukufakwa ngokuvamile kuhilela ukushisela okushisayo, okukhiqiza izixhumanisi eziqinile, ezingavuza, ezinomthelela ekuqiniseni uhlelo kodwa zidinga abasebenzi abanekhono ngesikhathi sokuhlanganisa.

Izishimula ze-PPR zithola izicelo ezibanzi ekuhlinzekweni kwamanzi ezindlini, ezinhlelweni zokushimula zezimboni, nasekulimeni ngezolimo ngenxa yokuqina kwazo nokumelana namakhemikhali. Imvelo yazo enobungani nemvelo nokukwazi ukugaywa kabusha kwandisa kakhulu ukukhanga kwazo emaphrojekthi okwakha esimeme.

Amapayipi e-PVC, enziwe nge-polyvinyl chloride, angaphakathi kwezinto zamapayipi ezisetshenziswa kakhulu emhlabeni jikelele. I-PVC yaziwa ngokumelana kwayo namakhemikhali, isisindo sayo esilula, nokwenza kalula. Amapayipi la ahlala isikhathi eside futhi ayamelana nokugqwala, okwenza alungele izinhlobonhlobo zezicelo ezingenawo umfutho njengokuconsa, ukulahla udoti, nokugqoka amakhebula.

Ngaphandle kwezinzuzo zabo eziningi, amapayipi e-PVC anemingcelela lapho kufika ezinhlelweni ezishisa kakhulu. Angakwazi ukugoba noma ukonakala lapho echayeke njalo emazingeni okushisa aphakeme, okwenza ukuthi angasetshenziswa ezinhlelweni zamanzi ashisayo. Ngaphezu kwalokho, kuphakanyiswe izinkathazo mayelana nezithako ezinobuthi ezisetshenziswa kwezinye izinqubo zokukhiqiza amapayipi e-PVC, okudinga ukuthi kutholwe imikhiqizo evela kubakhiqizi abahlonishwayo abanamathela emazingeni aphezulu kakhulu ekhwalithi nezokuphepha.

Ngokuyinhloko, amapayipi e-PVC asetshenziswa ezinhlelweni zokudonsa amanzi, ukunisela, kanye nezinhlelo zokudlulisa ugesi. Ukubiza kwawo okungabizi kanye nokutholakala kwawo kwenza kube ukukhetha okujwayelekile kwezinhlelo ezinkulu lapho amandla aphezulu kanye nokumelana nokushisa kungabalulekile.

Lapho kuqhathaniswa amapayipi e-PEX, e-PPR, kanye ne-PVC, kuyacaca ukuthi into ngayinye inikeza izinzuzo ezihlukile ezifanele izicelo ezithile. Amapayipi e-PEX aphumelela ekuguquguqukeni kanye nokumelana nezinga lokushisa, okwenza alungele izinhlelo zamanzi zasendlini kanye nezokushisa. Amapayipi e-PPR ahlinzeka ngokufakwa kukashisa okuhle kakhulu kanye nokumelana namakhemikhali, athandwa ngamanzi okuphuza kanye nokusetshenziswa kwezimboni. Amapayipi e-PVC, nakuba enomkhawulo ekumeleni ukushisa, ahlinzeka ngezixazululo ezingabizi kakhulu ezinhlelweni zokudonsa amanzi kanye nezingcindezi eziphansi.

Ngokombono wokufakwa, amapayipi e-PEX alula ukuwasebenzisa ngenxa yokuguquguquka kwawo nezindlela ezahlukahlukene zokuxhuma. I-PPR idinga izindlela ezikhethekile zokushisela ukuqinisekisa ukuxhumana okungavuqi, kanti i-PVC ithembele ekubambeni ngesixazululi esikhipha uketshezi, okuyinto elula kodwa engathetheleli kakhulu ngaphansi kwengcindezi yemishini. Ukuqina nakho kuyinto okufanele kucatshangelwe; amapayipi e-PPR agqama ngokukwazi ukugaywa kabusha kanye nokuba nobuhlobo nemvelo, kanti i-PVC idinga ukuphathwa ngokucophelela ngenxa yezithako ezingaba yimiphumela enobuthi.

Izinkampani ezifana ne-Shijiazhuang Shengshichang Trading Co., Ltd. zisebenzisa ubuchwepheshe bazo ezixazululweni zamapayipi ukunikeza imikhiqizo ye-PPR ne-PVC esezingeni eliphezulu ehlangabezana nezindinganiso eziqinile zemboni. Ukuzibophezela kwazo ekuhlinzekeni ngezinketho zamapayipi ezihlala isikhathi eside, eziphumelelayo, futhi eziphethe imvelo kugcizelela umkhawulo wazo wokuncintisana emakethe. Amabhizinisi anentshisekelo angahlola uhla olubanzi lwemikhiqizo nokwesekwa kwezobuchwepheshe ku-[Imikhiqizo](https://www.jhpiping.com/productList.html)ikhasi.

Ukukhetha phakathi kwemibhobho ye-PEX, i-PPR, ne-PVC kuncike kakhulu ezidingweni ezithile zephrojekthi yakho yokufakwa kwamanzi noma yokwakha. Imibhobho ye-PEX ilungele izinhlelo zamanzi eziguquguqukayo, ezishisayo kanye nokufudumala okukhanyayo. Imibhobho ye-PPR ilungele izicelo ezidinga ukumelana namakhemikhali kanye nokuvikela ukushisa, ikakhulukazi emikhakheni yamanzi okuphuza kanye neyemboni. Imibhobho ye-PVC ihlala iyisinqumo esihle kakhulu sokudonsa amanzi kanye nokusetshenziswa kwezintambo zikagesi ngenxa yokuqina kwayo nokubiza kwayo.

Ezebhizinisi ezifuna izixazululo zamapayipi eziqotho, ukubambisana nabahlinzeki abanolwazi njengeShijiazhuang Shengshichang Trading Co., Ltd. kungaqinisekisa ukufinyelela ezintweni ezisezingeni eliphezulu nesiqondiso esichwepheshile. Ngemininingwane eyengeziwe mayelana nenkampani yabo namagugu abo, vakashela ku-[Mayelana Nathi](https://www.jhpiping.com/about-us.html) ikhasi. Ngaphezu kwalokho, ukuze uthole ukwesekwa okuphelele nemibuzo yesevisi, i-[Ukusekelwa]( https://www.jhpiping.com/support.html)ikhasi linikeza izinsiza eziwusizo.

Ekugcineni, ukuqonda izici zezinto kanye nezidingo zokufakwa kwamapayipi e-PEX, e-PPR, kanye ne-PVC kuzokusiza ukhethe umkhiqizo ofanele kakhulu ozokala ukusebenza, izindleko, kanye nokusimama kwi-projekthi yakho.
