I-Strand Yensimbi Eqinisiwe Engcono Kakhulu Yensimbi Eqinisiwe
Intambo yensimbi ecindezelwe ngaphambili iyintambo yensimbi ecindezelwe eyakhiwe ngezintambo zensimbi ezi-2, 3, 7 noma 19 ezinamandla aphezulu, futhi iye yabhekana nokwelashwa kokukhululeka ekucindezelekeni (ukwelashwa kokuzinza), efanelekile kukhonkrithi ecindezelwe ngaphambili noma izinjongo ezifanayo.
Izici eziyinhloko zezintambo zensimbi ezicindezelwe ngaphambili amandla aphezulu, ukusebenza kahle kokuphumula, kanye nokuqondile uma zivuliwe. Izinga elivamile lamandla okudonswa yi-1860 MPa, futhi kunezinhlobo zamandla ezifana ne-1720, 1770, 1960, 2000, kanye ne-2100 MPa. Amandla okukhiqiza ale nsimbi nawo aphezulu kakhulu.
Induku yensimbi yensimbi enekhabhoni ephezulu idonswa kubanda ibe yintambo yensimbi ngemva kokwelashwa kobuso, bese inani elithile lezintambo zensimbi liphothwa libe yizintambo ngokwesakhiwo sentambo yensimbi, bese zakhiwa ngenqubo yokunciphisa ukucindezeleka. Ukuze kwandiswe ukuqina, ucingo lwensimbi lungaba ne-plating yensimbi noma engeyona eyensimbi noma i-coating, njenge-galvanizing, i-epoxy coating, njll. Ukuze kwandiswe amandla okubopha ngekhonkrithi, ubuso bungaba nama-nick nokunye. Intambo yensimbi ebunjiwe ecindezelwe ngaphambili idlula enkambisweni yokucindezela isikhunta ngemva kokubopha, isakhiwo siminyene futhi ungqimba olungaphezulu lufaneleka kakhulu ukubambelela. Ukuze wenze izintambo zensimbi ezingaxhunywanga (izintambo zensimbi ezingaxhunywanga) sebenzisa izintambo zensimbi ezijwayelekile ezicindezelwe ngaphambili, ezigcotshwe ngamafutha okulwa nokugqwala noma i-paraffin wax, bese zigoqwa nge-polyethylene ephezulu (HDPE).
