izindaba

I. Izici:

1. Ipayipi le-upvc, elaziwa nangokuthi ipayipi le-polyvinyl chloride eliqinile, ipayipi le-u-pvc, iwuhlobo lokumelana nokugqwala okuqinile, i-asidi, uwoyela we-alkali kasawoti kasawoti ophakathi kokuguguleka, isisindo esilula, amandla athile emishini, izimo ezinhle ze-hydraulic, ukufakwa okulula, kodwa kulula ukuguga, ukumelana nokushisa okuphezulu, kodwa ayikwazi ukumelana nomthelela, ilungele uhlelo lwamanzi asekhaya, uxhumano lwepayipi ye-DN50, i-DN65 ngaphezu kokuxhumeka kwendandatho.

2. Ipayipi le-pvc-u, elaziwa nangokuthi ipayipi le-polyvinyl chloride eliqinile, iwuhlobo olusha lwepayipi lokudonsa amanzi elinodonga lwangaphakathi olubushelelezi kanye nokuqiniswa okuqondile odongeni olungaphandle.Ilungele uhlelo lokudonsa amanzi emphakathini futhi yamukela isixhumi esibonakalayo sendandatho yerabha yohlobo lwe-“T”.

Okwesibili, I-engeli yokukhetha impahla:

I-1, i-PVC-U isetshenziselwa kakhulu ukwakha amanzi kanye ne-drainage, ukukhanya nokuqina, umbala omuhle, okhanyayo futhi oshelelayo, ukumelana nokuguga, impilo ende yesevisi, izakhiwo ezinhle kakhulu zomzimba namakhemikhali, ukumelana nokugqwala kwamakhemikhali, amandla omthelela aphezulu.

2. Ishubhu le-UPVC lineqhwa elibi kanye nokumelana nokushisa.Ukumelana nokoma okuhle, ukumelana nokugqwala okuqinile, ukumelana noketshezi oluphansi, amandla aphezulu emishini, impilo engeyona enobuthi, ukucinana kwamanzi okuhle, ipayipi le-PVC lilungele amapayipi ocingo nendle, namandla okufakwa kwamapayipi amakhulu angaphezulu, njengokupholisa isitshalo samandla. umbhoshongo.

Okwesithathu, i-engeli yokwakha:

I-1, i-PVC-U isetshenziselwa ikakhulukazi ukwakha amanzi kanye ne-drainage, ipayipi elishunyekiwe, indlela yokwakha eyinhloko encibilikayo eshisayo, nge-adhesive, ukwakhiwa kwasebusika akulula.

2. I-UPVC isetshenziselwa ukwakha amanzi kanye namapayipi okukhipha indle kanye nendle.Ingakwazi ukufaka esikhundleni samapayipi ensimbi avamile namapayipi anathayela.
