Kwintsimi yeenkqubo zeoli kunye negesi, iipayipi zensimbi ezingenamthungo zidlala indima ebalulekileyo. Njengombhobho wensimbi ochanekileyo, oqinileyo, unokumelana neendawo ezahlukeneyo ezinzima ezifana noxinzelelo oluphezulu, ukushisa okuphezulu, ukubola, njl. igesi yendalo.
1. Iimpawu
Imibhobho yentsimbi engenamthungo esetyenziswa kwindawo yeoli nerhasi inezi mpawu zilandelayo:
1. Ukuchaneka okuphezulu: Umbhobho wensimbi ongenamthungo unodonga olufanayo kunye nokuchaneka okuphezulu, okunokuqinisekisa ukulungelelanisa kunye nokutywinwa kombhobho.
2. Amandla aphezulu: Ekubeni imibhobho yensimbi engenamthungo ayinayo i-welds, inamandla aphezulu kunye nokuqina kwaye inokumelana neendawo ezinzima ezifana noxinzelelo oluphezulu kunye nokushisa okuphezulu.
3. Ukunganyangeki kwe-Corrosion: I-asidi kunye ne-alkali kwi-oyile kunye negesi yendalo iya kubangela ukubola kwimibhobho yentsimbi, kodwa isiseko sezinto ezisetyenziswa kwimibhobho yentsimbi engenamthungo iphezulu, ngoko inokumelana nokuhlwa okungcono kwaye inokuqinisekisa ukusebenza kakuhle kombhobho.
4. Ubomi obude: Ngenxa yenkqubo engqongqo yokuvelisa imibhobho yensimbi engenamthungo, ubomi babo benkonzo bunokuqinisekiswa ukuba buhlala amashumi eminyaka, ngaloo ndlela ukunciphisa ukuphindaphinda kokutshintshwa kunye neendleko ezihambelanayo.
2. Inkqubo yokuvelisa
Inkqubo yokwenziwa kwemibhobho yentsimbi engenamthungo kwindawo yeoli nerhasi ikakhulu ibandakanya la manyathelo alandelayo:
1. Ukunyibilika: Yongeza isinyithi esinyibilikisiweyo esithandweni sokunyibilikisa ukususa ukungcola kunye neegesi ukuqinisekisa ukucoceka kombhobho wentsimbi.
2. Ukuphosa ngokuqhubekayo: Intsimbi etyhidiweyo igalelwa kumatshini oqhubekayo wokuphosa ukuze uqiniswe ukwenza i-billet yensimbi.
3. Ukuqengqeleka: I-billet yensimbi ixhomekeke kwiinkqubo ezininzi zokuyijika ukuze iguqulwe kwaye yenze isakhiwo esifunekayo se-tubular.
4. I-Perforation: Umbhobho wensimbi ogqityiweyo utyhulwa ngomatshini wokubhobhoza ukwenza udonga lombhobho wensimbi ongenamthungo.
5. Ukunyangwa kobushushu: Unyango lobushushu lwenziwa kumbhobho wensimbi ongenamthungo we-perforated ukuphelisa uxinzelelo lwangaphakathi kunye nokuphucula iimpawu zayo zomatshini.
6. Ukugqiba: Ukugqitywa komphezulu kunye nokucutshungulwa komgangatho wemibhobho yentsimbi engenamthungo ephethwe ngubushushu ukuhlangabezana neemfuno zabathengi.
7. Ukuhlolwa: Ukuhlolwa okungqongqo kuqhutyelwa kwimibhobho yentsimbi egqityiweyo, kubandakanywa ukuchaneka kwe-dimensional, ukufana kodonga, umgangatho wangaphakathi nangaphandle, njl., Ukuqinisekisa umgangatho wemveliso.
Ngamafutshane, imibhobho yensimbi engenamthungo esetyenziswe kwintsimi yeoli kunye negesi, njengento echanekileyo, ephezulu, i-high-high-high-high-high-high-high-high-high-power pipe pipe, idlala indima ebalulekileyo kwimibhobho yokuhambisa kunye neenqanawa zoxinzelelo kwintsimi yamandla.
