Isingeniso somkhiqizo:
I-drainage ye-PVC-Uipayipiisebenzisa i-polyvinyl chloride resin njengento eluhlaza eyinhloko, yengeza izithasiselo ezidingekayo, futhi yakhiwe ngokucutshungulwa kwe-extrusion. Kuwuchungechunge lwemikhiqizo yamapayipi okukhipha amanzi ngobuchwepheshe obuvuthiwe futhi isetshenziswe kabanzi ekhaya nakwamanye amazwe. Umkhiqizo unezinzuzo zokuphila isikhathi eside, ukumelana nokugqwala, njll, okungenakuqhathaniswa namapayipi ensimbi; ilula ekwakhiweni, kulula ukuyiphatha nokuyifaka, futhi kulula ukuyixhuma. Isetshenziswa kabanzi kumadrainamu wokwakha umphakathi, i-drainage yamakhemikhali, kanye ne-drainage yamanzi emvula.

Umkhiqizo unezinzuzo zokuphila okude okungenakuqhathaniswa nokumelana nokugqwala kwamapayipi ensimbi; ilula ekwakhiweni, kulula ukuyiphatha nokuyifaka, futhi kulula ukuyixhuma. Isetshenziswa kabanzi kumadrainamu wokwakha umphakathi, i-drainage yamakhemikhali, kanye ne-drainage yamanzi emvula.
1. Ukuqina kobuso namandla aqinile wepayipi kuhle kakhulu, futhi isici sokuphepha se-ipayipiiphezulu.
2. Izindleko eziphansi, impilo ende yesevisi, impilo evamile yesevisi ingafinyelela eminyakeni engaphezu kwengu-50, asikho isidingo sokugcinwa nokulungiswa okuvamile.
3. Ipayipi linokumelana okuhle kakhulu nokugqwala kuma-asidi angaphili, ama-alkali, nosawoti. Ilungele ukukhishwa kwendle yezimboni kanye nokuthutha. Ayigqwali noma ayikali, ngakho-ke ngeke kube nokugqwala nokushwabana ngaphakathi.
Akulula ukuvinjwa, futhi udonga lwangaphandle ngeke lungcoliswe ngenxa yokugqwalaiphayiphi, eqinisekisa ubuhle besakhiwo.
4. I-coefficient yokushayisana kwamapayipi incane, ukugeleza kwamanzi kubushelelezi, akulula ukuvinjelwa, futhi umthwalo wokulungisa uncane.
5. Impahla inenkomba ye-oxygen ephezulu futhi iyazicisha ngokwayo.
6. I-coefficient yokwandisa yomugqa yepayipi incane, futhi inani lokuguqulwa okuthintekayo izinga lokushisa lincane. I-thermal conductivity kanye ne-elastic modulus incane, futhi ukusebenza kwe-anti-freezing kungcono kunaleyo yamapayipi e-cast iron drain.
7. Amapayipi nokufakwa kuxhunywe ngeglue, indlela yokwakha ilula, ukusebenza kulula, futhi ukusebenza kahle komsebenzi wokufaka kuphezulu.
8. Ayinabo ubuthi, ayinawo usawoti omthofu onobuthi namanye amakhemikhali anobuthi, futhi ayinabungozi emzimbeni womuntu.
