Eshabhu yeJinbin, iqoqo leama-valve ebhola e-carbon steel flangedzipakishwa emabhokisini ukuze zithunyelwe.

Yiziphi izinhlelo zokusebenza ezithile ze-flanged carbon steeli-valve yebhola?

I. Izimo Eziyinhloko Embonini Ye-Petrochemical

Njengenkundla esetshenziswa kabanzi, ilungele izimo zokusebenza njengokucwengwa kukawoyela ongahluziwe kanye nokuhlanganiswa kwamakhemikhali. Isibonelo, kumapayipi okuthutha umkhiqizo kawoyela wezinga eliphezulu lokushisa ezinkampanini zokucwenga namakhemikhali, izici zawo zokuvula nokuvala ngokushesha zingavimbela ukugcinwa okumaphakathi kanye ne-oxidation. Isakhiwo esingashi kanye ne-anti-static sihambisana nezinga le-API 607, siqinisekisa ukuphepha kokukhiqiza.

Ii. Ukusetshenziswa kwe-Power Energy Systems

Kumandla ashisayo kanye namaphrojekthi wokuhlanganisa, asetshenziselwa amanzi okuphakelayo okubhayela kanye namapayipi okuhambisa isitimu. Ifanele isitimu esinomfutho ophezulu kanye nezimo zokusebenza ezishisa kakhulu, ukuzinza koxhumano lwe-flange kungamelana nokudlidliza kwepayipi, futhi inqubo yonke yokubumba yomzimba we-valve ithuthukisa amandla okumelana nokuguquguquka kwengcindezi. Ezinhlelweni ezisizayo zamandla enuzi, imboni ye-valve yebhola eyenziwe nge-low-temperature carbon steel (LCB) ingashintshwa ukuze ihambisane nezimo ze-cryogenic ze -46 ℃, inikeze ukulawula okuthembekile kokuvala amapayipi amanzi okupholisa.

Iii. Izixhumanisi Ezibalulekile Embonini Yensimbi

Isetshenziselwa ukujikeleza kwamanzi okupholisa kanye nesistimu yokudlulisa igesi yesithando somlilo ekuncibilikiseni insimbi. Uma kuvezwa imidiya equkethe uthuli nezinto ezigqwala kancane, umzimba wevalvu yensimbi ye-carbon steel ubhangqwa namabhola ensimbi engagqwali aqinile ukuze amelane nokuguguleka kwezinhlayiyana nokuguga. Isakhiwo sokuzihlanza sesihlalo se-valve sinciphisa ingozi yokuvala. Ephayiphini lokwelapha igesi ye-flue, izici zayo ze-torque encane yokusebenza kanye nokuvula nokuvala ngokushesha kungasabela ngokushesha ekuguquguqukeni kwengcindezi yesistimu futhi kuqinisekise ukusebenza kahle kokuhlanzwa kwegesi ye-flue.

Iv. Izimo zikaMasipala kanye nezimboni ezijwayelekile

Emaphrojekthini okunikezwa kwamanzi asemadolobheni kanye namaphrojekthi okuhlanza indle, i-valve yebhola engu-4 Intshi eyenziwe nge-cast iron ne-carbon steel ifanele imidiya engagqwali njengamanzi kampompi namanzi ajikelezayo. Banikeza ukusebenza kwezindleko ezivelele, futhi ukuxhumeka kwe-flange kusiza ukugcinwa nokuhlolwa kamuva. Emapayipini okubulala amagciwane ngesitimu ezimbonini zemithi nokudla, amavalvu ebhola ensimbi ye-carbon angenawo amashaneli okugeleza akhona afile akhethwa ukuze kuvinjelwe insalela emaphakathi futhi ahlangabezane nezidingo zenhlanzeko.

V. Isicelo Esigabeni Sokudluliswa Kwegesi kanye Nokusabalalisa

Eziteshini zamasango emadolobheni kanye namapayipi egesi yemvelo amabanga amade, i-carbon steel flanged ball valve isiphenduke insiza eyinhloko yokunqanyulwa okuphakathi ngenxa yokuvaleka kwayo okungashi kanye nemiklamo ephikisana ne-static. Isakhiwo sebhola esingaguquki silungele amapayipi anobubanzi obukhulu asuka ku-DN50 kuya ku-DN600. Iqinisekisa ukuvalwa okuzinzile ngaphansi komehluko wengcindezi ephezulu kakhulu futhi ingaxhunywa ukude nohlelo lwe-ESD ukuze kuzuzwe ukuvala okuphuthumayo, okuqinisekisa ukuphepha kokudluliswa kwegesi.
