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:
Ukunyibilikisa>iingongo>ukuqengqeleka kwentsimbi>ukusarha>ukuxobula>ukugqobhoza>ukuchola>ukugquma>ukulayishwa kothuthu>umzobo obandayo>ukusika intloko>ukuvungula>ukugcina impahla
2. Iimpawu zombhobho wentsimbi engenamthungo:
Akunzima ukubona ukusuka ngasentla ukuhamba kwenkqubo: okokuqala, ubuninzi bodonga lwemveliso, ngakumbi uqoqosho kunye nokusebenzayo kuya kuba.Ubunzima bodonga oluncinci, indleko yokucubungula iya kuba phezulu;Okwesibini, inkqubo yemveliso imisela imida yayo.Ngokubanzi, ukuchaneka kombhobho wentsimbi engenamthungo kuphantsi: ubukhulu bodonga olungalinganiyo, ukukhanya okuphantsi komhlaba ngaphakathi nangaphandle kombhobho, ixabiso eliphezulu lokulinganisa, kwaye kukho imingxuma kunye namabala amnyama kumphezulu ngaphakathi nangaphandle kombhobho, ekunzima ukuwenza. susa;Okwesithathu, ukufunyaniswa kunye nokubunjwa kwayo kufuneka kusetyenzwe ngaphandle kweintanethi.Ngoko ke, ineenzuzo zayo kuxinzelelo oluphezulu, amandla aphezulu kunye nezixhobo zesakhiwo soomatshini.
3,Umbhobho wentsimbi odityanisiweyo
I-304 ityhubhu yokuhombisa yensimbi engenasici
I-304 ityhubhu yokuhombisa yensimbi engenasici
Umbhobho wentsimbi odityanisiweyo, obizwa ngokuba ngumbhobho odityanisiweyo ngokufutshane, ngumbhobho wensimbi engenasici odityaniswe kwipleyiti yentsimbi okanye umtya wentsimbi emva kokuba ukhutshiwe kwaye uqulunqwe ngumatshini kunye nokungunda.
1. Ipleyiti yentsimbi>Ukwahlula>Ukwenza>I-Welding ye-Fusion>Unyango lobushushu obuqaqambileyo>Unyango lwangaphakathi nangaphandle lwe-weld>Ubume>Ubukhulu>Uvavanyo lwangoku lwe-Eddy>Umlinganiselo we-laser diameter>Pickling>Warehousing
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.
