Ukukhetha impahla efanele yokuphonsa kubalulekile empumelelweni nasekuphakamiseni isikhathi sokuphila kwanoma iyiphi iphrojekthi yokuphonsa noma yokwakha. Ngemikhiqizo eminingi etholakalayo emakethe, ukuqonda umehluko obalulekile phakathi kwezinhlobo zamapayipi ezifana ne-PEX, i-PPR, ne-PVC kubalulekile ukuze wenze isinqumo esinengqondo. Lezi zinhlobo ezintathu zamapayipi zisetshenziswa kabanzi ezindlini, ezitolo, nasezimbonini ngenxa yezimpawu zazo ezihlukile nezinzuzo. Le ndatshana ihlinzeka ngokuqhathaniswa okuphelele kwepayipi le-PEX, le-PPR, kanye ne-PVC ukuze ikusize ukhethe isixazululo sokuphonsa esihambisana nezidingo zakho ezithile.

Iziphuzo ze-PEX (polyethylene ehlanganisiwe) ziwumjikelezo wezinsiza zeplastiki ezithambile eziklanyelwe ukuhlinzeka ngamanzi ashisayo naphakathi. Ukuthambile kwazo kuvumela ukufakwa kalula ngezinto ezincane futhi zikhombisa ukumelana okuhle nokuphuka. Iziphuzo ze-PPR (polypropylene random copolymer) ziqinile futhi zaziwa ngokumelana okuhle nezinto zokwakha kanye nokuphila isikhathi eside, zisetshenziswa kakhulu ezinhlelweni zokuhlinzeka ngamanzi ashisayo naphakathi. Iziphuzo ze-PVC (polyvinyl chloride) ziqinile futhi zisetshenziswa kabanzi ekukhipheni, emasimini, nasekuthumeleni amanzi abandayo ngenxa yokuba nezindleko eziphansi nokumelana nokugqwala. Ngamunye walawa makhono unikeza amandla ahlukile emishini kanye nokumelana nezinto ezikhemikhali ezihambelana nezicelo ezahlukene.

Iziphuzo ze-PEX ngokuvamile ziguquguquka kakhulu kune-PPR ne-PVC, okwenza zifaneleke ezindaweni lapho kudingeka khona ukujolisa ezikhaleni. Iziphuzo ze-PPR zinekhono eliphezulu lokumelana nokushisa nok pressure uma ziqhathaniswa ne-PVC futhi ngokuvamile zifaneleka ezinhlelweni zamanzi ashisayo. Iziphuzo ze-PVC zishibhile kakhulu futhi zitholakala kabanzi kodwa ngokuvamile zikhawulelwe ezisebenzisweni ezihilela izinga lokushisa eliphansi kanye no-pressure. Ukukhetha phakathi kwalezi zinto kuncike kakhulu ezidingweni zokusebenza, kuhlanganise nezinga lokushisa, u-pressure, nezimo zemvelo.

Lapho kuziwa ekumelaneni nezinga lokushisa, amapayipi e-PEX ngokuvamile angakwazi ukumelana nezinga lokushisa elingama-200°F (93°C), okwenza afaneleke kumasistimu wokuhambisa amanzi ashisayo nawapholile. Amapayipi e-PPR anikeza ukumelana nezinga lokushisa okuphezulu kakhulu, avame ukuhlolwa ukuze asetshenziswe ngokuqhubekayo ezingeni lokushisa elingama-180°F (82°C) kanye nezikhathi ezimfushane ezifika ku-230°F (110°C), okwenza afaneleke kakhulu ekunikezeni amanzi ashisayo nasezinhlelweni zokushisa. Amapayipi e-PVC, ngakolunye uhlangothi, anqunyelwe cishe ku-140°F (60°C) futhi awanconywa ukuze asetshenziswe emanzini ashisayo njengoba angase aguquke noma aphule ngaphansi kwezinga lokushisa eliphezulu.

Ngokwezi zilinganiso zokushisa, amapayipi e-PEX kanye ne-PPR ayizinketho ezikhethwayo zokusebenza ezihilela amanzi ashisayo, njengohlelo lokushisa lwezindlu noma izinqubo zezimboni ezidinga amapayipi anokumelana nokushisa. Amapayipi e-PVC avamise ukuvinjelwa kumanzi abandayo kanye nezinhlelo zokukhipha amanzi lapho ukuvezwa kokushisa kuncane. Ukukhetha ipayipi elinokumelana nokushisa okufanele kuqinisekisa ukuphepha nokuhlala isikhathi eside kohlelo lwakho lokuhambisa amanzi.

Ukumelana nokugqwala kuyinto ebalulekile ekukhetheni amapayipi. Amapayipi e-PEX ayakwazi ukumelana kakhulu nokugqwala nokwakheka kwezakhi, ngenxa yokwakheka kwawo kwepulasitiki, okwenza kube nokungabi khona kwezinkinga zokugqwala kwensimbi ezivamile kumapayipi ajwayelekile. Amapayipi e-PEX aphinde akwazi ukumelana nezinto eziningi zamakhemikhali, nakuba kufanele kuthathwe ukunakekela ngezixazululo ezithile. Amapayipi e-PPR anikeza ukumelana okuhle kakhulu namakhemikhali kumasidi, ama-alkali, kanye nosawoti, okwenza afaneleke ezinhlelweni zezimboni nasemanzini okuphuza lapho amakhemikhali anobungozi angase abe khona.

Iziphuzo ze-PVC zaziwa ngokumelana kwazo okuhle kakhulu nezinto eziningi zamakhemikhali kanye nokugqwala, ikakhulukazi ezinhlelweni zokuhlanza nezokukhipha amanzi. Nokho, ukuvezwa isikhathi eside kokukhanya kwe-UV kungaphula i-PVC ngaphandle kokuthi iphathwe ngokukhethekile noma iphathwe. Ezindaweni lapho ukuvezwa kwamakhemikhali noma ingozi yokugqwala iphezulu, i-PPR ne-PVC ivame ukukhethwa ngenxa yokumelana kwazo, kanti i-PEX ikhethwa ezinhlelweni zamanzi ahlanzekile.

Ukufaka uhlobo ngalunye lwepiphu kudinga amasu athile namathuluzi. Amabhayisikili e-PEX azwakala kahle ngenxa yokulula kokufakwa ngenxa yokuguquguquka kwawo; angagudluzwa ezikhaleni ngaphandle kokufaka okunye, kunciphisa umsebenzi nezindawo zokuvuza. Izindlela zokuxhuma zifaka phakathi ukujova, ukujova, noma ukufaka okushaywayo, kuvame ukufuna amathuluzi akhethekile kodwa kuhlinzeka ngokuhlanganiswa nokuhlakazeka okusheshayo.

Amathube e-PPR adinga ukuhlanganiswa kokushisa ukuze axhume izingxenye ngokuphakade. Le nqubo ihilela ukufudumala kwemikhono yephayiphi kanye nezinsiza ngesikhathi esifanayo bese kuhlanganiswa ukuze kudaleke uxhumano olungapheli, oluqinile. Ukuqeqeshwa okufanele kanye nemishini kubalulekile ukuqinisekisa ukuthi awekho amaphutha. Amathube e-PVC avamise ukuhlanganiswa nge-solvent cement, ehlanganisa ngokwemvelo iphayi kanye nezinsiza. Le ndlela ilula futhi ibiza kancane kodwa idinga ukunakwa ekulungiseleleni indawo kanye nezikhathi zokuphola.

Uhlelo ngalunye lwepiphu ludinga ukuhambisana nezindlela ezinhle zokufaka ukuze kuthuthukiswe ukusebenza nokuphila isikhathi eside. Kungakhathaliseki ukuthi usebenzisa ukujikeleza kwe-PEX, amandla okuhlanganisa kwe-PPR, noma i-PVC efakwe ngensipho, ukucabangela ngokucophelela amathuluzi nezindlela kuqinisekisa ukusethwa kweplumbing okuthembekile.

Zonke izinhlobo zamapayipi—i-PEX, i-PPR, ne-PVC—zakhelwe ukuphila isikhathi eside, kodwa ukuqina kwazo kuhluka ngokuya ngohlelo lokusebenza nezimo zemvelo. Amapayipi e-PEX ngokuvamile anempilo yokusebenza yeminyaka engama-40 kuya kwengama-50 uma efakwe kahle, anokumelana okuhle nokugqoka nezinguquko zengcindezi. Amapayipi e-PPR anempilo efanayo noma ende, ngokuvamile edlula iminyaka engama-50, ngenxa yokumelana kwawo nezinga eliphezulu lokushisa nezinto zokwakha.

Iziphuzo ze-PVC, uma zisetshenziswa ngaphakathi kwemikhawulo yazo yokushisa nengcindezi, zingahlala iminyaka engama-40 noma ngaphezulu. Nokho, ukuvezwa kokukhanya kwe-UV, ukuhlinzwa komzimba, noma izimo zamakhemikhali kunganciphisa impilo yazo esebenzayo. Ukufakwa kahle nokunakekelwa kudlala izindima ezibalulekile ekufinyeleleni lezi zikhathi zokuphila. Ukukhetha impahla efanele yephayiphi kukusiza ukuthi ugweme ukufaka kabusha njalo nezindleko ezihambisana nazo.

Izindleko zokuqala zezinto zokuhambisa amanzi zihluka kakhulu. Ama-PVC pipes ngokuvamile ayinketho engabizi kakhulu, okwenza kube kuhle kumaphrojekthi abheka izindleko. Ama-PEX pipes afinyelela enanini eliphakathi nendawo ngokonga okwenziwa ngokufaka ngokushesha kanye nezindleko zokusebenza ezincishisiwe. Ama-PPR pipes avame ukuba nezindleko eziphezulu ekuqaleni ngenxa yezindleko zezinto kanye nezidingo zokufakwa okukhethekile kodwa ngokuvamile anikeza ukonga kwezindleko ngokuhamba kwesikhathi ngenxa yokuhlala isikhathi eside nokugcinwa okuphansi.

Izindleko zesikhathi eside kufanele zicabangele hhayi kuphela intengo yokuthenga kodwa futhi nezindleko zokufaka, ukugcinwa, ukulungisa, kanye nezindleko zokushintsha. Isibonelo, ukuhamba kahle nokumelana nokugqwala kwe-PEX kunganciphisa izindleko zokulungisa, kanti ukumelana kem kemikhumbi kwe-PPR kunganciphisa ukonakala ezindaweni ezinzima. Izindleko eziphansi ze-PVC kanye nokutholakala kwayo kabanzi kwenza kube ukukhetha okuhle kwezinye izinhlelo zamanzi abandayo nezokukhipha. Ukuhlola lezi zinto kuqinisekisa ukuthi ukhetha isixazululo sokuphuma esinokonga kakhulu sephrojekthi yakho.
