Ukuhlolwa: uhlalutyo lokubunjwa kweekhemikhali, uvavanyo loxinzelelo, uvavanyo lokucwenga kunye novavanyo loxinzelelo lwamanzi kufuneka lwenziwe kumbhobho wentsimbi osetyenziselwa ukuthuthwa kwamanzi ngokubanzi.

GB5310, GB6479, GB9948iintlobo ezintathu zemibhobho yentsimbi eqhelekileyo, ukongeza kwityhubhu yokuthutha ulwelo kufuneka ivavanywe, kodwa iphinde ifuneke ukuba yenze uvavanyo lokuvutha kunye novavanyo lwempembelelo;Iimfuno zokuhlolwa kokwenziwa kwezi ntlobo zintathu zemibhobho yentsimbi zingqongqo.

GB6479umgangatho wenza iimfuno ezikhethekileyo lobushushu obuphantsi ifuthe ukuqina kwemathiriyeli.

GB3087 umgangatho umbhobho yentsimbi, ukongeza kwiimfuno zovavanyo ngokubanzi kumbhobho yentsimbi zothutho fluid, kodwa kufuna uvavanyo ukugoba abandayo.

I-GB/T8163 yentsimbi eqhelekileyo yombhobho, ukongeza kwiimfuno zovavanyo ngokubanzi kumbhobho wentsimbi wokuthutha ulwelo, ngokweemfuno zesivumelwano sokuqhuba uvavanyo lokuvutha nokugoba okubandayo.Iimfuno zokuvelisa ezi ntlobo zimbini zemibhobho azikho ngqongqo. njengezo zeentlobo ezintathu zokuqala.

Ukuvelisa: I-GB / T / 8163 kunye ne-GB3087 umbhobho wentsimbi oqhelekileyo wamkela isithando somlilo esivulekileyo okanye ukunyibilikiswa kwe-converter, ukungcola kwayo kunye neziphene zangaphakathi zingaphezulu.

GB9948ukunyibilikiswa kweziko lombane.Uninzi longezwa kwinkqubo yokucoca iziko kunye nezithako ezimbalwa kunye neziphene zangaphakathi.

GB6479kwayeGB5310imigangatho ngokwayo ichaza iimfuno zokusulungekiswa ngaphandle kwesithando somlilo, kunye nokungcola okuncinci kunye neziphene zangaphakathi kunye nomgangatho ophezulu wezinto eziphathekayo.

Le migangatho emininzi yemibhobho yentsimbi yenziwa ngokulandelelana komgangatho ukusuka ezantsi ukuya phezulu:

I-GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479

Ukukhethwa: phantsi kweemeko eziqhelekileyo, i-GB / T8163 ipayipi yentsimbi eqhelekileyo ifanelekile kubushushu boyilo bungaphantsi kwe-350 ℃, uxinzelelo lungaphantsi kwe-10.0mpa yeemveliso zeoli, i-oyile kunye negesi kunye neemeko eziphakathi koluntu;

Kwimveliso yeoli, i-oyile kunye negesi ephakathi, xa ubushushu boyilo bungaphezulu kwe-350 ℃ okanye uxinzelelo likhulu kune-10.0mpa, kufanelekile ukukhetha.GB9948 or GB6479umbhobho wentsimbi osemgangathweni;

GB9948 or GB6479umgangatho kufuneka kwakhona usetyenziswe kwimibhobho esebenza kufutshane ne-hydrogen okanye kwindawo ethanda ukutyiwa kuxinzelelo.

Ubushushu obuphantsi ngokubanzi (ngaphantsi kwe-20℃) kusetyenziswa umbhobho wentsimbi yekhabhoni kufuneka kusetyenzisweGB6479umgangatho, kuphela uxela iimfuno zobushushu obuphantsi befuthe lokuqina kwemathiriyeli.

GB3087 kunyeGB5310imigangatho imiselwe ngokukodwa imigangatho yebhoyila yentsimbi yombhobho."Imigaqo yokulawula ukhuseleko lwebhoyila" igxininise ukuba zonke ezidityaniswe netyhubhu zebhoyila zezobume bolawulo, ukusetyenziswa kwezinto kunye nomgangatho kufuneka kuhambelane nemithetho yokhuseleko lwebhoyila, ke ngoko, ibhoyila, isikhululo samandla, ukufudumeza kunye nemveliso yepetrochemical. isixhobo esisetyenziswa kumbhobho kawonke-wonke umphunga kufuneka isetyenziswe (ngokubonelela inkqubo) GB3087 okanye umgangathoGB5310.

Kuyafaneleka ukuba uqaphele ukuba umgangatho wemigangatho yemibhobho yensimbi efanelekileyo, amaxabiso emibhobho yensimbi aphakamileyo, njengayeGB9948ngaphezu kwe-GB8163 ixabiso lezinto eziphathekayo liphantse li-1/5, ngoko ke, ekukhethweni kwemigangatho yempahla yepayipi yensimbi, kufuneka ithathelwe ingqalelo ngokwemiqathango yokusetyenziswa, ethembekileyo kunye nezoqoqosho.Kufuneka kwakhona kuqatshelwe ukuba iityhubhu zentsimbi ngokuhambelana ne-GB/T20801 kunye ne-TSGD0001, GB3087 kunye ne-GB8163 aziyi kusetyenziswa kwi-GC1 piping (ngaphandle kokuba i-ultrasonic nganye, umgangatho ongekho ngaphantsi kwe-L2.5, ingasetyenziswa kwi-GC1 (1) yoyilo lwemibhobho. uxinzelelo alukho ngaphezu kwe-4.0Mpa).

(2) Umbhobho wensimbi ongenamthungo ophantsi

Kwizixhobo zokuvelisa i-petrochemical, imigangatho yombhobho yentsimbi engenamthungo exhaphakileyo yentsimbi ye-chromium-molybdenum kunye nentsimbi ye-chromium-molybdenum vanadium
