Ukhetho oluchanekileyo lwemibhobho yentsimbi engenamthungo eneneni inolwazi kakhulu!

Ziziphi iimfuno zokukhetha imibhobho yentsimbi engenamthungo yokuthutha ulwelo oluqhele ukusetyenziswa kwishishini lethu lenkqubo?Jonga isishwankathelo sabasebenzi bethu boxinzelelo:

Imibhobho yentsimbi engenamthungo yimibhobho yentsimbi ngaphandle kwe-wels eyenziwe ngeendlela zonyango ezishushu ezinjengokubhoboza kunye nokuqengqeleka okushushu.

Ukuba kukho imfuneko, umbhobho ovuthiweyo ovuthiweyo unokuthi ubanda ngakumbi - utsalwe kwimilo efunekayo, ubungakanani kunye nokusebenza.Okwangoku, imibhobho yentsimbi engenamthungo (DN15-600) yeyona mibhoyile isetyenziswe ngokubanzi kwizixhobo zemveliso yepetrochemical.

(一) umbhobho wentsimbi engenamthungo

Ubungakanani besicelo: I-Steam egxile kwi-steam kunye namanzi abilayo kubaphene boxinzelelo oluphantsi kunye nophakathi.

GB5310:

Ibakala lensimbi yensimbi: 20g njl.

Ububanzi besicelo: i-superheated steam medium yebhoyila yoxinzelelo oluphezulu

Ukuhlolwa: Ngokubanzi imibhobho yentsimbi ye-fluid kufuneka ihlalutshini yokuqulunqwa kwemichiza, uvavanyo olunamangile, uvavanyo lokuthelekisa kunye novavanyo lwe-hydraulic.I-GB5310, GB6479, kunye ne-GB4448 Imibhobho yentsimbi esemgangathweni, ukongeza kwiimvavanyo ekufuneka zenziwe kwimibhobho yentsimbi yezithuthi, iimvavanyo ezipholileyo nazo ziyafuneka;iimfuno zokuhlolwa kwemveliso kule mibhobho emithathu yentsimbi ingqongqo.Umgangatho we-GB6479 wenza iimfuno ezikhethekileyo zokuqina kwefuthe eliphantsi lobushushu bezinto eziphathekayo.Ukongeza kwiimfuno zovavanyo ngokubanzi zemibhobho yentsimbi yezothutho zamanzi, imibhobho yentsimbi ye-GB3087 ikwafuna ukuvavanywa okubandayo.I-GB / T8163 Imibhobho yentsimbi esemgangathweni, ukongeza kwiimfuno zovavanyo ngokubanzi malunga nemibhobho yentsimbi yothutho, ngokwesivumelwano ifuna uvavanyo lokwandiswa kunye novavanyo olubandayo.Iimfuno zokwenziwa kwezi ntlobo zimbini zeebhubhu azikho ngqongqo njengeentlobo ezintathu zokuqala.

UKUPHUNYEZWA:I-GB9948 isebenzisa ubukhulu becala i-smelce yombane.Uninzi lwabo luye lwajoyina inkqubo yokucoca ngaphandle kwesithando somlilo, kwaye ukubunjwa kunye neziphene zangaphakathi zincinci.I-GB6479 yeMigangatho ye-GB64310 ngokwayo yachaza iimfuno zokulungiswa ngaphandle kwesixhobo, kunye neyona ndlela incinci yokunyanzela kunye neziphene zangaphakathi, kunye nomgangatho ophezulu wezinto eziphezulu

Ukukhetha: Ngokubanzi, i-GB / T8163 imibhobho yentsimbi esemgangathweni ilungele ioyile, ioyile kunye negesi yoluntu enamaqondo osasazo oLuntu anamaqondo obushushu angaphantsi kwama-350 ° C kunye noxinzelelo olungaphantsi kwe-10.0MPA;Ngeoyile, ioyile kunye negesi kunye negesi, xa ubushushu boyilo bungaphezulu kwe-350 ° C okanye xa uxinzelelo lungaphezulu kwe-10.0mpa, i-GB6478 imibhobho yentsimbi ephantsi kufuneka isetyenziswe;kwimibhobho esebenza kwi-hydrogen, okanye imibhobho esebenza kwiindawo ezinoxinzelelo lwe-corrosion, imigangatho ye-GB9948 okanye ye-GB6479 nayo kufuneka isetyenziswe.Yonke imibhobho ye-carbon ye-carbon esetyenziswa kumaqondo obushushu asezantsi (ngaphantsi kwe-2 ° C) kufuneka afumane umgangatho we-GB6479, kwaye kuphela echaza iimfuno zobushushu obuphantsi kwengqondo.Imigangatho ye-GB3087 kunye ne-GB5310 yimigangatho ebekwe ngokukodwa kwiibhobho zensimbi zebhoyili.Imigaqo "yokubekwalela i-boiler yoKhuseleko" igxininisa ukuba yonke imibhobho enxulumene nompheli ingowemigaqo yezinto ezibekekileyo kunye nemigangatho kufuneka ihambelane neemfuno ze "Boiler Sest".Ngoko ke, zisetyenziselwa kwiibhoyili, izikhululo zamandla, ukufudumeza kunye nezixhobo zokuvelisa i-petrochemical.Yonke imibhobho yomphunga kawonke-wonke (enikezelwe yinkqubo) kufuneka yamkele imigangatho ye-GB3087 okanye i-GB5310.Kuyafaneleka ukuba uqaphele ukuba ixabiso lemibhobho yensimbi enemigangatho emihle yombhobho yensimbi iphezulu kakhulu.Ngokomzekelo, ixabiso le-GB9948 liphantse libe yi-1/5 ephezulu kunexabiso lezinto ze-GB8163.Ke ngoko, xa ukhetha imilinganiselo yokwenza umbhobho wensimbi yentsimbi, kuya kuthathelwa ingqalelo iimeko zokusetyenziswa, ekufuneka kuthathelwe ingqalelo kwaye zibe noqoqosho.Kuya kuqatshelwa ukuba imibhobho yentsimbi ngokungqinelana ne-GB / TS20801 kunye ne-Tsgd0001, GB3087 imigangatho ye-GB8113 ayizukusetyenziselwa i-GC1 imibhobho ye-GC1, i-GB8163 ayiyi kuphantsi kwe-L2.5, kwaye inokuba njalo Isetyenziselwa i-GC1 ngoxinzelelo loyilo olungekho mkhulu kune-4.0mpa Pipeliline).

(二)Umbhobho wentsimbi ephantsi ingenamthungo

Kwizixhobo zemveliso yepetrochemical, i-chromium esetyenziswa i-chromium-molybdenum yentsimbi kunye neChromium-dadium ye-GB6478 "I-GB6478" I-GB6478 "I-GB6410" ingenamthungo umbhobho wentsimbi kwibhoyila yoxinzelelo oluphezulu》I-GB9448 iqulethe i-chromium-molybdenum ye-chromium yentsimbi: I-15CRO, i-1CR2MO, i-ch5310: 1crrb, i-ch5310 iqulethe i-chromium ye-chromium ye-chromium ye-chromium kunye ne-chromium molybdenum dadim Amabakala ezinto ezibonakalayo:

(三) umbhobho wentsimbi engenamthungo

Ihlala isetyenziswa i-steiness yentsimbi engenasithulo yentsimbi:

Kukho imigangatho emihlanu: GB / T14976, GB13296, GB6478, GB6479, GB5310.Phakathi kwawo, kuphela amaBanga aSebenzisayo ngentsimbi engenanto kudweliswa kwimigangatho emithathu yokugqibela, kwaye awasetyenziswanga amabakala asetyenziswayo.

Ke ngoko, xa imigangatho yentsimbi engenamthungo isetyenziswa kubunjineli, i-GB / T14976 kunye ne-GB13296 imigangatho isetyenziswa ngokusisiseko.

I-GB / T14976 "I-Stainess yentsimbi yentsimbi ye-Steeel yeSoft yoThutho":

Amabakala ezinto ezibonakalayo: 304, 304L kunye nezinye iintlobo ezili-19 zilungele ukuthuthwa kwabantu ngokubanzi.

I-GB13296 "Iibhubhu zentsimbi engenamthungo yentsimbi yeebhoyila kunye nabatshintshisi bobushushu":

Amanqaku ezinto eziphathekayo: 304, 304L kunye nezinye iindidi ezingama-25.

Phakathi kwabo, i-ultra-low-carbon stainless steel (304L, 316L) inokumelana nokugqwala okugqwesileyo.Ngaphantsi kweemeko ezithile, inokuthi ithathe indawo yensimbi ezinzileyo (321, 347) yokumelana nokubola kwimidiya;I-ultra-low-carbon steel stainless ineempawu ezisezantsi zobushushu obuphezulu, ngokuqhelekileyo Isetyenziswa kuphela kumaqondo obushushu angaphantsi kwe-525℃;Intsimbi ethembekileyo ye-Austetitic Staight inamanyano olulungileyo kunye neepropathi zobushushu beqondo lokushisa, kodwa i-TI nge-321 i-oxid i-oxids, ilahlekile ngexesha lokusebenza kwe-ilding, ngaloo ndlela ilahlekelwe yi-anting xa isetyenziswa ngakumbi, olu hlobo lwezinto lusetyenziswa ngokubanzi Izihlandlo ezibalulekileyo, ezingama-304, 316 zinentsebenzo yokulwa ngokuchasene ne-corrosion, ixabiso lixabiso eliphantsi, ngoko ke lisetyenziswa ngokubanzi.
