Ukumelana nokugqwala kweamapayipi e-iron ductile
♦Impahla yokuvikela ukugqwala
I-cast iron ine-anti-corrosion property ephelele, ngokombiko, kwakukhona amapayipi ensimbi afakwe eminyakeni engu-300 edlule asasetshenziswa, futhi amacala amaningi abonisa ukuthi amapayipi ensimbi aneminyaka engaphezu kwekhulu yokuphila komsebenzi.Mayelana nokusetshenziswa kwamapayipi e-iron ductile, umlando ungaphezu kweminyaka engama-30.Kodwa i-ductile cast iron icishe ifane nensimbi empunga ekwakhekeni kwamakhemikhali.Futhi iqukethe i-silicon, ikhabhoni nezinye izakhi eziningi kunensimbi.Ukumelana ne-ductile cast iron ukugqwala nakho kufana nalokho kwe-grey cast iron.Lokhu kuye kwaboniswa ngokusetshenziswa futhi kwafakazelwa ngokwamandla.
♦ Ukuvikelwa kokugqwala kwepayipi
Kuyiqiniso ukuthi ipayipi lensimbi elingaphansi komhlaba elidlulisa amanzi aphuzwayo negesi lizothonywa kakhulu ngamakhemikhali kanye nempahla yenhlabathi ngokuqondile.Isici esibaluleke kakhulu esibangela ukugqwala kulapho amapayipi ehlanganiswa ukuze abe yibhizinisi elide neliqhubekayo lokufaka ugesi.Ngamanye amazwi, ukugqwala kwenhlabathi kuzokhombisa izici ezihlukene kumapayipi ahlukene.Ngokusekelwe kulo mehluko, yenza i-concentration cell.Ingxenye yeseli kungenzeka ye-concentration cell izoba namandla kakhulu.Uma ukubeka into efaka ugesi emhlabathini kuzoletha ulayini omude wamandla kagesi bese i-anode yamanje izokwenza ukugqwala okukhulu kwe-boil.Ipayipi lensimbi elishiselwe yisibonelo esisobala.Ipayipi lensimbi elinezimbotshana, eliphethe ilunga lalo lomshini noma lohlobo lwe-T futhi livalwe nge-insulating rubber gasket, kunejoyinti lokufakwayo njalo ngemva kwamamitha angu-4-6.
♦ Ukumelana nokugqwala okubangelwa amandla kagesi
Njengoba i-ductile iron inezinga eliphezulu lokumelana nogesi, iwukumelana nokugqwala okubangelwa amandla kagesi.
