Hunhu hwakakwirira hweS235 J0 Spiral Steel pombi inoita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa. Iva maindasitiri, ekutengeserana kana mapurojekiti ekuzvivara, ichi chigadzirwa chakagadzirirwa kuzadzisa zvinodiwa nevashandisi vayo. Kuita kwayo kwakavimbika uye kusimba kunoita kuti isimbe-inoshanda mhinduro chero projekiti inoda spiral yakakundwa arc tubes.
Pamusoro peS235 J0 Spiral Steel pombi, yedu yechigadzirwa mutsara zvinosanganisirawoA252 giredhi 3 Simbi pombi. Chigadzirwa chakagadzirwa uchishandisa iyo yazvino yekugadzira matekinoroji anoona iyo yepamusoro yepamusoro uye yekuvimbika miganhu. Nesimba rayo rakakwirira kwazvo simba uye rakanakisa corrosion rinopesana, A252 giredhi 3 Simbi pombi yakanakira kukumbira application.
Isu tinodada nekupa iyo yakazara mutsara weiyo spiral yakakundwa Arc yakavezwa pombi iyo inosangana uye inodarika maindasitiri zviyero. Kuzvitsaurira kwedu kumhando uye kuratidzira kwakatiita mutengesi akavimbika kune iyo simbi pombi indasitiri. Nekuzvipira kune kugona, isu tinoramba tichisundira miganhu yechimbi pombi yekugadzira.
Kana zvasvika pakupfira yakakundwa ARC yakavezwa pombi, zvigadzirwa zvedu zvakaisa chiyero chekuita, kusimba uye kuvimbika. S235 J0 Spiral Steel pombi uye A252 Giredhi 3 Simbi Pipi ingori mienzaniso miviri yekuzvipira kwedu kupa vatengi vedu nemhinduro dzakanakisa. Isu tinotarisa pane zvemhando uye zvakazvipira kusangana nezvinodiwa zvevatengi vedu uye nekupfuura kwavo kutarisira.
Mukupfupikisa, yedu S235 J0 Spiral Steel pombi uye A252 Giredhi 3 Simbi Pombi ndiyo mhedzisiro yekucheka-mashandiro emuchadenga uye yepamusoro mhizha. Zvigadzirwa izvi zvinopa maitiro asina kubhadharwa, achivaita sarudzo yakakwana yeiyo dzakasiyana siyana dzekushandisa. Kunyangwe iko kuvakwa, midziyo yezvivakwa kana mapurojekiti eindasitiri, yedu spiral yakakundwa Arc yakavezwa mapepa akagadzirirwa kuendesa mibairo yepamusoro. Vimba kuti hunyanzvi hwedu uye ruzivo ruchakupa iwe wepamusoro emhando yepamusoro pombi pombi.
