Izinhlelo zokuhambisa amanzi ziyingxenye ebalulekile kunoma yiluphi uhlelo lokwakhiwa kwezindawo zokuhlala, zezentengiselwano, noma zezimboni. Ziqinisekisa ukulethwa okuphephile, okuphumelelayo kwamanzi okuphuza, ukugeza, nezinye izidingo ezibalulekile. Ukukhetha amapayipi asetshenziswa kulezi zinhlelo kuthinta kakhulu ukuqina kwawo, ukwethembeka, nokusebenza kwawo jikelele. Phakathi kwezinhlobo zamapayipi ezisetshenziswa kakhulu ezinhlelweni zokuhambisa amanzi kukhona amapayipi e-PEX namapayipi e-PVC, ngalinye linezici ezihlukile nezinzuzo zalo.

Amapayipi e-PEX (cross-linked polyethylene) athole ukuthandwa ngenxa yokuguquguquka kwawo nokumelana kwawo, kanti amapayipi e-PVC (polyvinyl chloride) aziwa ngamandla awo nokuba nenzuzo kwezindleko. Lesi sihloko sinikeza ukuqhathanisa okuphelele phakathi kwamapayipi e-PEX namapayipi e-PVC, sihlose ukusiza amabhizinisi nabasontisi ukuthi benze izinqumo ezinolwazi. Ngaphezu kwalokho, imininingwane ngamanye izinto zamapayipi njengamapayipi e-PPR izothintwa ukuze kunikezwe ukuqonda okubanzi kwezinketho zamapayipi.

Ukuqonda izici, izinzuzo, kanye nemikhawulo yalawa mapayipi kubalulekile ekukhetheni umkhiqizo ofanele owenzelwe izidingo ezithile zokuhlinzekwa ngamanzi. Lesi sihloko siphinde sigqamise indima yezinkampani ezifana neShijiazhuang Shengshichang Trading Co., Ltd. ekuhlinzekeni izixazululo zamapayipi ezisezingeni eliphezulu.

Amapayipi e-PEX enziwa nge-polyethylene ehlangene, impahla ethuthukisa izici zokushisa nomshini wepayipi. Inqubo yokuhlanganisa ithuthukisa ukumelana kwe payipi nokushisa nomfutho, okwenza ilungele izinhlelo zokuhlinzekwa ngamanzi ashisayo abandayo. Amapayipi e-PEX ayabonakala ngokuguquguquka kwawo, okuvumela ukuhanjiswa okulula ezindaweni ezinzima kanye nokunciphisa izindawo zokuqhakaza, kunciphisa izindawo ezingaba khona zokuqhakaza.

Enye yezici ezibaluleke kakhulu zamapayipi e-PEX ukumelana kwawo kahle nokushisa. Angakwazi ukumelana nezimo zokuqanda kanye nokushisa okuphezulu kufika ku-200°F (93°C) cishe, okwenza afaneleke ezinhlotsheni eziningi zezicelo, okubandakanya ukushisa kwe-radiant floor kanye nokusabalalisa amanzi okuphuzwayo.

Ukufakwa kwamapayipi e-PEX kulula futhi kuyashesha, njengoba angahlanganiswa kusetshenziswa izindlela ezahlukahlukene njengokucindezela, ukubopha, noma izixhumi ezicindezelayo. Leli lula lokufakwa kunciphisa izindleko zomsebenzi nesikhathi, okuyinto ebalulekile emaphrojekthi ezohwebo. Ngaphezu kwalokho, amapayipi e-PEX abonisa ukuqina okuphezulu, ukumelana nokugqwala, ukukala, kanye nomonakalo we-chlorine, okwandisa kakhulu impilo yawo yesevisi.

Amapayipi e-PVC enziwa nge-polyvinyl chloride, ipulasitiki eqinile eyaziwa ngamandla ayo kanye nokumelana namakhemikhali. Amapayipi la asetshenziswa kabanzi ezinhlelweni zokuhambisa amanzi kanye nezokunisela ngenxa yokuthi ayabiza futhi ahlala isikhathi eside. Ukuqina kwe-PVC kunikeza ukuqina, okwenza la mapayipi akwazi ukumelana nomonakalo ongokwenyama futhi akwazi ukubhekana nezingcindezi eziphakeme zamanzi.

Enye yezinzuzo eziyinhloko zamapayipi e-PVC ukumelana kwawo kahle namakhemikhali, okwenza afanele ukuthutha amanzi okuphuzwayo kanye nemikhiqizo ehlukahlukene yamakhimikhali ezindaweni zezimboni. Awaqedi kalula noma awonakali lapho evezwa ezindaweni eziningi zamatshe kanye ne-alkali, ahlinzeka ngokuthembeka ezindaweni ezahlukahlukene.

Enye inzuzo yamapayipi e-PVC ukuthi ayabiza. Bavame ukubiza kancane kunamapayipi e-PEX, okwenza kube yisinqumo esithandwayo samaphrojekthi amakhulu anesabelomali. Kodwa-ke, ngokungafani namapayipi e-PEX, amapayipi e-PVC awanayo i-flexibility futhi adinga izingxenye eziningi kanye neziyintaba, okungandisa isikhathi sokufakwa kanye nezindawo ezingasevuza.

Uma siqhathanisa imibhobho ye-PEX neye-PVC, izinto eziningana zigqama: ukuqina, izindleko, kalula kokufakwa, nomthelela kwemvelo. Ngokuqondene nokuqina, imibhobho ye-PEX ngokuvamile idlula i-PVC ngenxa yokuguquguquka kwayo nokumelana nokugqabuka ngaphansi kwengcindezi noma izinguquko zokushisa. Imibhobho ye-PVC, nakuba iqine, ivame ukuba buthakathaka ngokuhamba kwesikhathi, ikakhulukazi uma ibonakala ekukhanyeni kwe-UV.

Ngokombono wokufakwa, imibhobho ye-PEX inikeza izinzuzo ezibalulekile. Ukuguquguquka kwayo kuvumela ukusetshenziswa okuncane kwezixhumi, kunciphisa ubungozi bokuvuza nezindleko zabasebenzi. Imibhobho ye-PVC, njengoba iqine, idinga ukusika okunembayo nokuhlanganisa, okungandisa isikhathi sokufakwa. Kodwa-ke, ukubiza kwemibhobho ye-PVC kuyenza ibe nomthelela kumaphrojekthi anezimali ezingekho ngaphansi.

Izinto ezithinta imvelo nazo zibalulekile. Amapayipi e-PEX enziwa nge-polyethylene, impahla enomthelela omncane emvelweni ngesikhathi sokukhiqizwa uma iqhathaniswa ne-PVC, ebandakanya i-chlorine nezinye izithako eziphakama izinkinga zemvelo. Ngaphezu kwalokho, amapayipi e-PVC angasetshenziswa futhi uma kucutshungulwa kahle, yize izinselele zokulahlwa zihlala zikhona.

Ngokufingqa, amapayipi e-PEX aphumelela kakhulu ekuqineni kanye nokufakwa okulula, kanti amapayipi e-PVC ahlinzeka ngokonga izindleko kanye nokumelana namakhemikhali aqinile. Ukukhetha phakathi kwawo kuncike ezidingweni ezithile kanye nezimo zesistimu yokuhlinzekwa kwamanzi.

Ngokufingqa, womabili amapayipi e-PEX kanye ne-PVC anamandla awo ahlukile nemikhawulo yawo. Amapayipi e-PEX alungele izicelo ezidinga ukuguquguquka, ukumelana nezinga lokushisa eliphezulu, kanye nokufakwa okulula. Ahlinzeka ngokuqina kwesikhathi eside kanye nokunciphisa ukugcinwa, okwenza kube ukukhetha okuseqhulwini kwezinhlelo eziningi zokufakwa kwamanzi.

Amapayipi e-PVC, ngakolunye uhlangothi, ayonga, ayamelana namakhemikhali, futhi aqinile, alungele izinhlelo ezinkulu zokuhlinzekwa ngamanzi noma izinhlelo zokunisela lapho izindleko kanye nokuchayeka kumakhemikhali kuyizinto ezibalulekile. Ukuqina kwawo, nakuba kuyimikhawulo kwezinye izimo, kunikeza ukuzinza komqambimanga.

Ezamabhizinisi afuna izixazululo zamapayipi ezingathembekile, izinkampani ezifana ne-Shijiazhuang Shengshichang Trading Co., Ltd. zinikeza ubuchwepheshe kanye nemikhiqizo ebanzi okubalwa kuyo amapayipi e-PEX, e-PVC, kanye ne-PPR. Ukuzibophezela kwabo kwekhwalithi kanye namanani ancintisanayo kubenza kube uzakwethu onokwethenjelwa emaphrojekthi okuhlinzekwa ngamanzi.

Ukuze uthole izinketho zemikhiqizo eziningiliziwe nokucaciswa, ukuvakashela ikhasi le-Imikhiqizo kuyalulekwa. Ngaphezu kwalokho, ukufunda kabanzi mayelana nefilosofi yenkampani namakhono okukhiqiza kungenziwa ekhasini labo elithi Mayelana Nathi. Ukuze uthole usizo lobuchwepheshe nemibuzo, ikhasi elithi Ukusekela linikeza usizo olubalulekile.

Ekugcineni, ukukhetha ipayipi elilungile kuncike ezintweni ezithile zephrojekthi okubalwa kuzo izinga lokushisa lamanzi, ukuchayeka kumakhemikhali, indawo yokufakwa, kanye nesabelomali. Ukuqonda izinzuzo zokuqhathanisa zamapayipi e-PEX kanye ne-PVC kusiza abenzi bezinqumo ukuthi bakhe isixazululo samapayipi esisebenza kahle kakhulu nesisimeme ezinhlelweni zabo zokuhambisa amanzi.
