Izixhumi ze-PP yizinto zokuxhuma amapayipi ezenziwe nge-polypropylene (PP) futhi zisetshenziswa ikakhulukazi ukuze zixhume futhi zifake izinhlelo zamapayipi e-PP. Le mveliso ifaka phakathi izixhumi eziqondile ezine-flange, ama-tee, ama-elbow, njll., futhi uxhumano lwamapayipi lufezwa ngokubopha nge-adhesive, ukuhlanganiswa kokushisa, kanye nezixhumi ezine-thread.

I-PVC pipe fittings ayakwazi ukumelana nokugqwala futhi zihlweight, okwenza zifaneleke embonini yezemithi kanye nokwelashwa kwamanzi angcolile. Izinqubo zokukhiqiza zifaka phakathi ukucindezela nokwakha nge-extrusion, zinikeza izinzuzo ekukhiqizeni nasekulawuleni izindleko. Ngesikhathi sokufaka, isikhala sepipe kumele sibe ne-chamfer, futhi i-adhesive kumele ifakwe ngesilinganiso esijwayelekile se-200g/m². I-joint kumele igcinwe ibheke phezulu imizuzu emithathu ngesikhathi sokufaka, futhi akufanele kube namandla angaphandle asetshenziswe ngesikhathi sokuphola. Izinga lokushisa lendawo yokufaka kumele lingaphansi kuka-5℃, futhi ukufakwa akufanele kwenziwe emvula noma emanzini.
