Umugqa Wokukhipha Ipayipi le-PVC-UH/UPVC/CPVC

Ipayipi le-PVC liyipayipi lepulasitiki elenziwe ngezinto ze-thermoplastic polyvinyl chloride (PVC). Ipayipi le-PVC livame ukusetshenziswa kuzo zonke izinhlelo zokusebenza kanye nezimboni futhi liza ngezinhlobo ezahlukene. Amapayipi e-PVC avame ukusetshenziswa ekukhipheni amanzi, ekunikezeni amanzi, ekuniseleni, ekuphatheni amakhemikhali, ekufakeni amapayipi omoya, emsebenzini we-duct kanye nasezinhlelweni zokuphatha imfucuza. Imikhiqizo yokuphakelwa kwamapayipi e-PVC etholakalayo i-schedule 40 PVC, i-schedule 80 PVC, ipayipi le-PVC lezinga lefenisha, ipayipi le-CPVC, ipayipi le-drain waste vent (DWV), ipayipi eligobile, ipayipi le-PVC elicacile kanye nepayipi eliphindwe kabili lokufaka amanzi.

Ipayipi leShejuli 40 kanye neshejuli 80 ziyipayipi eliguquguqukayo eliqinisekisiwe futhi elibhalisiwe ngokwekhodi nezindinganiso zemboni zokusetshenziswa okuningi kwanamuhla. Ipayipi le-PVC lezinga lefenisha litholakala ngemibala ehlukene ngaphandle kwezimpawu noma amalebula futhi linomphetho ohlanzekile, ocwebezelayo. Ipayipi le-DWV lisetshenziselwa ukuphathwa kwesakhiwo sezinto ezilahliwe. Ipayipi eliguquguqukayo liyipayipi le-PVC eliguquguqukayo lezinhlelo zokusebenza lapho ipayipi eliqinile lingafaneleki noma lingasizi. Ipayipi elicacile livumela ukuqapha okubonakalayo kokugeleza koketshezi kanye nekhwalithi yepayipi. Ipayipi eliphindwe kabili lokulawula lenzelwe ukuhlangabezana nemithetho yemboni ukuze kubanjwe ukuvuza noma ukwehluleka kwesistimu ukuthuthukisa ukuphepha noma lapho kudingeka khona.

Ipayipi le-PVC litholakala ngobukhulu obusukela ku-1/8 intshi kuya ku-24 intshi ububanzi. Amanye amasayizi avame kakhulu yipayipi le-PVC elingu-½ intshi, 1 ½ intshi, 3 intshi, 4 intshi, 6 intshi, 8 intshi kanye neli-10 intshi. Amapayipi e-PVC athunyelwa ngezigaba ezijwayelekile ezingamafidi ayi-10 noma ubude obungamafidi angama-20. Lokhu konga izindleko zokuphatha futhi kuvumela ukuhlinzeka ngemikhiqizo enentengo ephansi. Sinezingxenye ezingamafidi ayi-5 ze-SCH 40 PVC, SCH 80 PVC kanye nefenisha ye-PVC etholakala kuphela endaweni yokuthumela impahla.

Uma i-PVC isetshenziswa ukubhekisela kumapayipi epulasitiki, ngokuvamile iqondwa njenge-uPVC (i-PVC engafakwanga ipulasitiki) ngomklamo. Ipayipi le-uPVC liyipayipi lepulasitiki eliqinile futhi liyindlela evame kakhulu yamapayipi e-PVC asetshenziswa ezakhiweni. Amapayipi e-uPVC akhiqizwa ngaphandle kwama-ejenti epulasitiki angangezwa ukwenza izinto ze-PVC ziguquguquke kakhudlwana. Ipayipi eliguquguqukayo liyisibonelo se-PVC efakwe ipulasitiki ngenxa yokuguquguquka kwayo okufana nepayipi.
