Kulolu suku neminyaka, kunezindlela eziningi ezithakazelisayo nezokudala zamapayipi. Enye yezinto ezithandwa kakhulu zokufakela amapayipi ekhaya namuhla i-PEX (Cross-Linked Polyethylene), isistimu yokufaka amapayipi enembile futhi evumelana nezimo ngokwanele ukuze ikwazi ukuzungeza izithiyo zaphansi nezindonga, nokho iqine ngokwanele ukumelana nokugqwala namanzi ashisayo. Amapayipi e-PEX anamathiselwe kupulasitiki noma kokufakwa kwensimbi kuhabhu kusistimu ngokuklebhula esikhundleni seglue noma ukushisela. Uma kukhulunywa ngepayipi le-PEX vs i-PVC eguquguqukayo, yikuphi ukukhetha okungcono?

I-PVC eguquguqukayo iyona kanye ezwakala ngayo. Kuyi-aipayipi eliguquguqukayo elilingana ne-PVC evamilefuthi ingaxhunywa kokufakwayo kwe-PVC ngosimende we-PVC oguquguqukayo. I-PVC eguquguqukayo ivamise ukujiya kakhulu kunepayipi le-PEX ngenxa yobukhulu bayo obungama-40 nokuqina kodonga. Funda ukuze uthole ukuthi ipayipi le-PEX noma i-PVC evumelana nezimo ingcono yini kuhlelo lwakho lokusebenza!

isithako esibonakalayo
Lezi zinto ezimbili zibukeka zifana ngenxa yezakhiwo zazo eziguquguqukayo, kodwa ukwakheka kwazo, ukusetshenziswa nokufakwa kwazo kuhluke kakhulu. Sizoqala ngokubheka indaba. I-PEX imele i-polyethylene ehlangene. Yenziwe nge-polyethylene ephezulu kakhulu enezibopho ezixhumene nesiphambano esakhiweni se-polymer. Kuzwakala kuyinkimbinkimbi, kodwa kusho nje ukuthi impahla iyavumelana nezimo futhi ingamelana nezingcindezi eziphezulu (kufika ku-180F ngezinhlelo zokusebenza zamapayipi).

I-PVC eguquguqukayo yenziwe ngezinto eziyisisekelo ezifanayo njenge-PVC evamile: i-polyvinyl chloride. Kodwa-ke, ama-plasticizers ayengezwa ku-compound ukuze anikeze ukuguquguquka. I-PVC eguquguqukayo ingakwazi ukumelana namazinga okushisa ukusuka ku -10F kuya ku-125F, ngakho-ke ayiwafanele amanzi ashisayo. Noma kunjalo, iwusizo kakhulu ezinhlelweni ezimbalwa, esizozihlanganisa esigabeni esilandelayo.

isicelo
Umehluko phakathi kwamapayipi amabili mkhulu kunesakhiwo sawo. Zibuye zisetshenziswe ezinhlelweni ezihluke ngokuphelele. Ipayipi le-PEX lisetshenziswa kakhulu kumapayipi asekhaya nakwezentengiselwano ngenxa yezidingo zawo ezincane zesikhala kanye nokumelana nokushisa okuphezulu. I-PEX ilungele le misebenzi ngoba ingagoba kalula futhi igobe kunoma iyiphi indlela ngaphandle kokusebenzisa izesekeli eziningi kakhulu. Kulula ukuyifaka kunethusi, obekuyizinga lamanzi ashisayo ezizukulwaneni ngezizukulwane.

Ipayipi le-PVC eliguquguqukayo alikwazi ukuphatha amanzi ashisayo, kodwa linezinye izinzuzo. Ukuqina kwayo kwesakhiwo kanye namakhemikhali kwenza i-PVC eguquguqukayo ilungele amachibi nokunisela. I-chlorine esetshenziselwa amanzi echibi ayinawo umthelela omncane kuleli payipi eliqinile. I-Flex PVC nayo ilungele ukuchelela engadini, njengoba ingazulazula noma kuphi lapho uyidinga khona ngaphandle kwenqwaba yezesekeli ezicasulayo.

Njengoba ubona, ukuqhathanisa ipayipi le-PEX ne-PVC evumelana nezimo kufana nokuhlanganisa iqembu le-baseball neqembu le-hockey. Bahluke kakhulu, abakwazi ngisho ukuncintisana bodwa! Nokho, akukho lapho umehluko uphela khona. Sizobheka esinye sezici eziphawuleka kakhulu zohlobo ngalunye lwepayipi: ukufakwa. Funda kabanzi mayelana nezinhlelo zokusebenza ze-PEX kulesi sihloko esivela ku-The Family Handyman.

Faka
Kulokhu sizoqala nge-PVC eguquguqukayo, njengoba ifakwe ngendlela esiyijwayele kakhulu ku-PVC Fittings Online. Ipayipi ifakwe uhlobo olufanayo lweukufakwa njengepayipi elivamile le-PVC. Ngenxa yokuthi inokwakheka kwamakhemikhali okucishe kufane ne-PVC ejwayelekile, i-PVC eguquguqukayo ingaqanjwa futhi ifakwe usimende kokufakwayo kwe-PVC. Kuyatholakala usimende we-PVC oguquguqukayo oklanyelwe ukumelana nokudlidliza nezingcindezi ezivame ukutholakala kumachibi okubhukuda nezinhlelo ze-spa.

ama-pex tee, ama-crimp ring namathuluzi ama-crimp amapayipi e-PEX asebenzisa indlela yokuxhumana eyingqayizivele. Esikhundleni seglue noma i-welding, i-PEX isebenzisa insimbi enameva noma izifakelo zepulasitiki ezihlukanisiwe noma ezibekwe kuhabhu. Amashubhu epulasitiki ananyathiselwa kulezi ziphetho ezinemihlaba ngokusebenzisa izindandatho zensimbi, eziboshwe ngamathuluzi akhethekile okugoqa. Ukusebenzisa le ndlela, ukuxhumana kuthatha imizuzwana embalwa kuphela. Uma kuziwa ekufakweni kwamapayipi ekhaya, amasistimu e-PEX athatha isikhathi esincane ukuwafakaithusi noma i-CPVC. Isithombe esingakwesokudla sibonisa i-polyalloy PEX tee, indandatho ye-crimp yethusi, nethuluzi le-crimp, konke kutholakala esitolo sethu!
