  • Umbhobho wentsimbi yokuhlobisa intsimbi

    Umbhobho wentsimbi yokuhlobisa intsimbi

    Umbhobho wokuhombisa wensimbi engenastainless ukwabizwa ngokuba ngumbhobho wentsimbi odityanisiweyo, obizwa ngokuba ngumbhobho odityanisiweyo ngokufutshane.Ngokuqhelekileyo, intsimbi okanye intsimbi yentsimbi idityaniswe kumbhobho wentsimbi emva kokuba i-crimped kwaye yenziwe yiyunithi kunye nokubumba.Inkqubo yokuvelisa umbhobho wensimbi odibeneyo ilula, ukusebenza kakuhle kwemveliso kuphezulu, kukho iintlobo ezininzi kunye neenkcukacha, kwaye iindleko zezixhobo zincinci, kodwa amandla aqhelekileyo angaphantsi kunombhobho wensimbi ongenamthungo.

     

    Kukho iintlobo ezininzi zemibhobho yentsimbi, kodwa isetyenziselwa ezi njongo zilandelayo:

    1,Ulwahlulo lwemibhobho yensimbi engenasici

    1. Ukuhlelwa ngokwendlela yemveliso:

    (1) Umbhobho ongenamthungo – umbhobho otsalwa ngokubanda, umbhobho okhutshiweyo, umbhobho oqengqelekayo obandayo.

    (2) Umbhobho odityanisiweyo:

    (a) Ngokohlelo lwenkqubo - umbhobho we-welding we-gas okhuselweyo, umbhobho we-arc welding, umbhobho we-resistance welding (i-frequency ephezulu, i-frequency ephantsi).

    (b) Yahlulwe yaba ngumbhobho odityanisiweyo othe tye kunye nombhobho odityanisiweyo ojikelezayo ngokweweld.

    2. Ukuhlelwa ngokwemilo yecandelo: (1) umbhobho wensimbi ojikelezayo;(2) ityhubhu yeRectangular.

    3. Ukuhlelwa ngokobunzima bodonga - umbhobho wentsimbi obhityileyo eludongeni, umbhobho wentsimbi ongqindilili

    4. Ukuhlelwa ngokusetyenziswa: (1) Imibhobho ye Civil yahlulwe yaba yimibhobho engqukuva, imibhobho yoxande kunye nemibhobho yeentyatyambo, esetyenziselwa ukuhombisa, ukwakhiwa, ubume, njl.njl;

    (2) Umbhobho woshishino: umbhobho wentsimbi wemibhobho yoshishino, umbhobho wentsimbi wombhobho jikelele (umbhobho wamanzi okusela), isakhiwo somatshini/umbhobho wokuhambisa ulwelo, umbhobho wokutshintsha ubushushu kwibhoyila, umbhobho wococeko lokutya, njl. , njengepetrochemical, iphepha, amandla enyukliya, ukutya, isiselo, amayeza kunye namanye amashishini aneemfuno eziphezulu ze-fluid medium.

    2,Umbhobho wentsimbi ongenamthungo

    Umbhobho wentsimbi engenamthungo luhlobo lwentsimbi ende enecandelo elinomngxuma kwaye akukho malungu ajikelezayo.

    1. Inkqubo yokuvelisa kunye nokuhamba kombhobho wentsimbi engenamthungo:

    2. Iimpawu zombhobho wentsimbi odityanisiweyo:

    Akunzima ukubona ukusuka ngasentla ukuhamba kwenkqubo: okokuqala, imveliso iveliswa ngokuqhubekayo kunye ne-intanethi.Ukuqina kodonga, kokukhona utyalo-mali olukhulu kwiyunithi nakwisixhobo sokuwelda, kwaye okona kuncinci ukonga kunye nokusebenza.Udonga oluncinci, umlinganiselo ophantsi we-input-output ratio uya kuba;Okwesibini, inkqubo yemveliso imisela izibonelelo zayo kunye nokungalunganga.Ngokuqhelekileyo, umbhobho wentsimbi odityanisiweyo unobuchwephesha obuphezulu, ubukhulu bodonga obufanayo, ukukhanya okuphezulu kwangaphakathi nangaphandle komgangatho wemibhobho yensimbi engenasici (ukukhanya kombhobho wensimbi obekwe yinqanaba lomphezulu wepleyiti yentsimbi), kwaye unokuba nobukhulu obungenasizathu.Ngoko ke, iquka uqoqosho kunye nobuhle bayo ekusetyenzisweni kwe-high-precision, i-medium-low pressure fluid.

     

    Kukho i-chlorine ion kwindawo yokusetyenziswa.Ii-ion zeklorini zikho ngokubanzi, njengetyuwa, ukubila, amanzi olwandle, impepho yolwandle, umhlaba, njl. njl. Intsimbi engatyiwayo idla ngokukhawuleza xa kukho iiyoni zekloridi, nkqu nentsimbi eqhelekileyo enekhabhoni ephantsi.Ngoko ke, kukho iimfuno zendawo yokusetyenziswa kwensimbi engenasici, kwaye kuyimfuneko ukuyisula rhoqo ukususa uthuli kwaye uyigcine icocekile kwaye yomile.

    I-316 kunye ne-317 i-stainless steels (jonga ngezantsi kwiipropati ze-317 ze-stainless steels) ziyi-molybdenum equkethe i-stainless steels.Umxholo we-molybdenum kwi-317 insimbi engenasici iphezulu kancinane kune-316 yensimbi engenasici.Ngenxa ye-molybdenum kwintsimbi, ukusebenza ngokubanzi kwale ntsimbi kungcono kune-310 kunye ne-304 yensimbi engenasici.Ngaphantsi kweemeko eziphezulu zeqondo lokushisa, xa ukuxinwa kwe-asidi ye-sulfuric kungaphantsi kwe-15% kwaye kungaphezulu kwe-85%, i-316 insimbi engenasici ineendlela ezininzi zokusetyenziswa.I-316 insimbi engenasici ikwane-chloride yokumelana nokugqwala, ngoko idla ngokusetyenziswa kwindawo yaselwandle.Ngophuhliso loqoqosho lwentlalo, ukusetyenziswa kombhobho wensimbi engenasici kuye kwathandwa kakhulu.Iya kuzisa utshintsho olutsha kuzo zonke iinkalo.
