Ukuhlangabezana neemfuno eziphezulu zabathengi zoxinzelelo lwamanzi kunye noxinzelelo lomoya kuyilo lweflange iityhubhu zokufudumeza zombane,ukulungelelaniswa okubanzi kuyafuneka kwimilinganiselo emininzi efana nokukhethwa kwezinto, uyilo lolwakhiwo, inkqubo yokuvelisa, kunye nokuqinisekiswa kokusebenza. Isicwangciso esithile simi ngolu hlobo lulandelayo:
1,Ukukhetha izinto eziphathekayo: Phucula amandla oxinzelelo kunye nesiseko sokutywinwa
1. Ukukhethwa kwezinto eziphambili zombhobho
Amandla aphezulu kunye nezinto ezinganyangekiyo kwi-corrosion zikhethwa kwiimeko zokusebenza zoxinzelelo oluphezulu (uxinzelelo lwamanzi≥10MPa okanye uxinzelelo lomoya≥6MPa), njenge:
Intsimbi ye-Stainless 316L (imelana nemithombo yeendaba ezonakalisayo, amandla acinezelayo≥520MPa);
I-Incoloy 800 (imelana nobushushu obuphezulu, uxinzelelo oluphezulu kunye ne-oxidation, ilungele indawo yobushushu obuphezulu, amandla esivuno≥240MPa);
Ingxubevange ye-Titanium / i-Hastelloy alloy (yemithombo yeendaba eyingozi kakhulu kunye noxinzelelo oluphezulu njengamanzi olwandle kunye nezisombululo ze-asidi).
Ubukhulu bodonga lombhobho bubalwa ngokwemigangatho ye-GB / T 151 Ukutshintsha Ubushushu okanye i-ASME BPVC VIII-1, iqinisekisa umda wobunzima bodonga.≥I-20% (efana nokubala ubukhulu bodonga + i-0.5mm yokhuseleko xa uxinzelelo olusebenzayo luyi-15MPa).
2. I-Flange kunye ne-seal ehambelanayo
Uhlobo lweFlange: Kwiimeko zoxinzelelo oluphezulu, i-neck welding flanges (WNRF) okanye i-integral flanges (IF) isetyenzisiweyo, kwaye indawo yokutywina ikhethwa njenge-mortise kunye ne-tenon (TG) okanye i-ring joint (RJ) ukunciphisa umngcipheko wokutywinwa kokuvuza kwendawo.
I-gasket yokutywina: Khetha i-gasket esongiweyo yesinyithi (enezangqa zangaphakathi nangaphandle) (ukumelana noxinzelelo≤I-25MPa) okanye i-octagonal metal ring gasket (uxinzelelo oluphezulu kunye nobushushu obuphezulu, ukumelana noxinzelelo≥40MPa) ngokweempawu zesiphakathi. Izinto ze-gasket zihambelana nempahla yombhobho (njenge-316L gasket kunye ne-316L flange).
2,Uyilo lwesakhiwo: Ukomeleza uxinzelelo kunye nokuthembeka
1. Ukulungelelaniswa kwesakhiwo soomatshini
Uyilo lokugoba: Kuphephe ukugoba i-engile yasekunene kwaye usebenzise iradiyasi enkulu egobileyo (R≥I-3D, i-D yi-diameter yombhobho) ukunciphisa uxinzelelo loxinzelelo; Xa ubeka imibhobho emininzi, isasazwa ngokulinganayo ukulungelelanisa amandla e-radial.
Isakhiwo esomelezayo: Yongeza amakhonkco enkxaso (isithuba≤1.5m) okanye ezakhelwe phakathi izibonda zokumisa kwindawo ethe ngqo endeityhubhu yokufudumeza ukukhusela i-deformation yomzimba wetyhubhu phantsi koxinzelelo oluphezulu; Icandelo loqhagamshelo phakathi kweflange kunye nomzimba wombhobho lithatha indawo yenguqu ejiyileyo (i-gradient groove welding) ukuqinisa ukuxhathisa kokukrazula kwe-weld seam.
2. Ukutywinwa kunye noyilo lokudibanisa
Inkqubo ye-Welding: Umzimba wombhobho kunye ne-flange ifakwe ngokupheleleyo i-welded (njenge-TIG welding + i-filler wire), kunye ne-100% yovavanyo lwe-X-ray (RT) okanye uvavanyo lokungena (PT) lwenziwa emva kwe-welding ukuqinisekisa ukuba i-weld seam ayinayo i-pores kunye nokuqhekeka;
Uncedo lokwandiswa: Iityhubhu yokutshintshiselana ngobushushu idityaniswe kwiplate yetyhubhu isebenzisa inkqubo emibini yokwandiswa kwe-hydraulic kunye nokutywinwa kwe-welding. Uxinzelelo lokwandisa≥kabini uxinzelelo olusebenzayo lokuthintela ukuvuza okuphakathi kwimingxuma yepleyiti yetyhubhu.
3,Inkqubo yokuvelisa: ulawulo olungqongqo lweziphene kunye nokuhambelana
1. Ukulawulwa kokuchaneka komatshini
Ukusika umbhobho kwamkela ukusika kwe-laser / CNC, kunye nesiphelo sobuso be-perpendicularity≤0.1mm; flange ukutywina umphezulu uburhabaxa≤Ra1.6μ m, umngxuma webholi yempazamo yonikezelo olufanayo≤0.5mm, ukuqinisekisa amandla afanayo ngexesha lofakelo.
Ukuzaliswa kwe-Magnesium oxide powder: usebenzisa iteknoloji yokudibanisa i-vibration, ukuzalisa ubuninzi≥2.2g/cm³, ukuphepha ukufudumala kwendawo okanye ukungaphumeleli kwe-insulation okubangelwa ngamacandelo angenanto (ukumelana ne-insulation≥100MΩ/500V).
2. Uvavanyo loxinzelelo kunye nokuqinisekiswa
Uvavanyo lwangaphambili lwasefektri:
Uvavanyo lwe-Hydrostatic: Uxinzelelo lovavanyo luyi-1.5 amaxesha oxinzelelo lokusebenza (njenge-10 MPa yoxinzelelo lokusebenza kunye ne-15 MPa yovavanyo lovavanyo), kwaye akukho xinzelelo lokunciphisa emva kokubamba imizuzu engama-30;
Uvavanyo loxinzelelo (olusebenzayo kumajelo erhasi): Uxinzelelo lovavanyo ngamaxesha e-1.1 yoxinzelelo lokusebenza, ludityaniswe ne-helium mass spectrometry ukufunyaniswa kokuvuza, kunye nesantya sokuvuza≤1 × 10 ⁻⁹mbar· L/s.
Uvavanyo olutshabalalisayo: Isampuli isetyenziselwa uvavanyo loxinzelelo lokuqhuma, kwaye uxinzelelo lokudubula kufuneka lube≥Amaxesha ama-3 oxinzelelo lokusebenza ukuqinisekisa umda wokhuseleko.
4,Ukulungelelaniswa okusebenzayo: ukujamelana neemeko ezinzima zokusebenza
1. Imbuyekezo yokwandiswa kwe-thermal
Xa ubude beityhubhu yokufudumeza is ≥2m okanye umahluko wobushushu≥100℃, icandelo lolwandiso lwamaza okanye uqhagamshelo oluguquguqukayo kufuneka lifakwe ukuhlawulela ukuguqulwa kwe-thermal (imali yokwandisaΔ L=α L Δ T, aphoα kukwandiswa kwe-coefficient yomgca wesixhobo) kwaye unqande ukungaphumeleli kokutywina komphezulu okubangelwa luxinzelelo lobushushu.
2. Ulawulo lomthwalo womphezulu
Imithombo yeendaba zoxinzelelo oluphezulu (ingakumbi iigesi) zinovakalelo kubushushu bendawo kwaye zifuna ukuncitshiswa komthwalo womphezulu (≤8W/cm²). Ngokwandisa inani okanye ububanzi beityhubhu yokufudumezas, ukusabalalisa ukuxinana kwamandla, kunye nokuthintela ukunyuswa okanye ukunyuswa kwezinto (ezifana nomthwalo womphezulu≤6W/cm² ngexesha lokufudumala komphunga).
3. Uyilo lokuhambelana nemidiya
Ulwelo olunoxinzelelo oluphezulu oluqulathe amasuntswana/ubumdaka, isikrini sokucoca (ngokuchaneka kwe≥I-100 mesh) okanye isigqubuthelo sesikhokelo kufuneka sifakwe kwindawo yokungena ityhubhu yokufudumeza ukunciphisa ukhukuliseko; Imidiya ebolileyo ifuna ukunyangwa komphezulu owongezelelweyo/ukutshiza (njengepolytetrafluoroethylene coating, ukumelana nobushushu.≤260℃).
5,Uyilo olusemgangathweni kunye nolwenzelwe wena
Ukubonelela ngeengxelo zezinto eziphathekayo, ukufaneleka kwenkqubo ye-welding (PQR), kunye neengxelo zovavanyo loxinzelelo ngokuhambelana nemigangatho kazwelonke (i-GB 150 "Ii-Pressure Vessels", i-NB / T 47036 "i-Electric Heating Elements") okanye imigangatho yamazwe ngamazwe (ASME BPVC, PED 2014/68 / EU).
Ukuhlangabezana neemfuno ezikhethekileyo zabathengi (ezifana noxinzelelo oluphezulu lokufudumeza kwe-API 6A izixhobo ze-wellhead kunye nokufudumeza koxinzelelo olunzulu lolwandle), sisebenzisana nabathengi ukulinganisa iimeko zokusebenza (ezifana nohlalutyo olulinganiselweyo lwento yokusabalalisa uxinzelelo kunye nokuphucula intsimi ye-CFD) kunye nokwenza ngokwezifiso iinkcukacha ze-flange (ezifana neeflanges ezikhethekileyo kunye ne-sulfure resistant materials).
shwankathela
Ngokusetyenziswa kwenkqubo epheleleyo "yesiqinisekiso samandla ezinto eziphathekayo→uyilo lokumelana nomthwalo wesakhiwo→ulawulo lokuchaneka kwemveliso→uvavanyo kunye nokuqinisekiswa kwe-loop evaliweyo", iflange ityhubhu yokufudumala yombane inokufikelela ekusebenzeni okuthembekileyo phantsi kweemeko zombane ophezulu. Undoqo kukulungelelanisa umthamo wokuthwala uxinzelelo, ukusebenza kokutywinwa, kunye nokuzinza kwexesha elide, ngelixa kuthathelwa ingqalelo iimpawu zomthengi ophakathi (ubushushu, ukubola, ukuhamba kwesantya) kuyilo olujoliswe kuyo, ekugqibeleni ukuhlangabezana nemfuneko yokhuseleko lomda wokhuseleko lwamanzi / uxinzelelo lomoya.≥1.5 amaxesha iiparamitha zoyilo.
