Indlela yokufaka yokuhlanganisa irabha yokwandisa
1. Okokuqala, beka iziphetho ezimbili zokufakwa kwamapayipi okudingeka kuxhunywe phansi endaweni evundlile. Lapho ufaka, qala ubeke isiphetho esiqinile sokufakwa kwamapayipi flat.
2. Okulandelayo, zungezisa i-flange ekuhlanganyeleni kwenjoloba eguquguqukayo ukuze uqondanise izimbobo ze-flange ezizungezile. Faka intambo ngezikulufu, qinisa amantongomane, bese uqondanisa i-flange ngakolunye uhlangothi lwepayipi ilingane ngokuvundlile ne-flange ekuhlanganyeleni kwenjoloba eguqukayo. Zungezisa i-i-flangeendaweni ehlangene yerabha eguquguqukayo ukwenza umlomo we-flange ubhekane. Vula izikulufu namantongomane ngokuvundlile ukuze uxhume ngokuqinile lokhu okuthathu ukuze uvimbele ukuvaleka okuxekethile.
Lapho ufaka ijoyinti yenjoloba, isikulufu esingaphandle sebhawodi lehange kufanele sidlulele kuzo zombili izinhlangothi zekhanda lokuxhuma, kanye nebhawodi lehange embobeni engaphakathi ngayinye.ipuleti le-flangekufanele iqiniswe ngokuqhubekayo nangokulinganayo ngokucindezela i-engeli ephezulu ukuvimbela ukuchezuka kokucindezela. Ijoyinti elinentambo kufanele liqiniswe ngendlela efanayo ngesikrufu esijwayelekile, futhi ukusetshenziswa kwenduku yephoyinti akufanele kubangele ukushelela, unqenqema noma ukuqhekeka kwelunga elinyakazayo. Ukugcinwa njalo kufanele kwenziwe ukuze kuvinjwe ukuxegiswa kanye nokubanga ithreyi noma ukuvuza.
Izinyathelo zokuphepha zokufakwa kwejoyinti lokunwetshwa kwenjoloba
1.Ngaphambi kokufakwa, amamodeli afanelekile kanye nokucaciswa kufanele kukhethwe ngokusekelwe kungcindezi, indlela yesixhumi esibonakalayo, impahla, kanye nenani lesinxephezelo sepayipi, futhi inani eliphelele kufanele likhethwe ngokuvumelana nemithethonqubo yokuvala umsindo kanye nokususwa kokunciphisa umsindo. Naka ukulungiswa kwengcindezi yokusebenza. Lapho ipayipi lidala ingcindezi yokusebenza yesikhashana futhi lidlula ingcindezi, isixhumi esinegiya elingaphezu kokucindezela kufanele sisetshenziswe.
2. Ngesikhathi esifanayo, lapho impahla yepayipi ine-asidi eqinile, i-alkali, uwoyela, izinga lokushisa eliphezulu, noma ezinye izinto zokusetshenziswa ezikhethekile, isixhumi esiyigiya elilodwa eliphakeme kunomfutho wepayipi kufanele sisetshenziswe. Ipuleti le-flange elixhuma ukuhlangana kwerabha kufanele libe i-valve flange noma ipuleti le-flange ngokuhambisana ne-GB/T9115-2000.
3. Qaphela ukuthi ijoyinti lerabha kufanele licindezelwe futhi liqiniswe futhi ngaphambi kokuba lisetshenziswe ngemva kokuphoqwa, njengalapho lifakwa noma ngaphambi kokuba livalwe isikhathi eside futhi liphinde livulwe.
4. Naka ukulungiswa kwayo kwezinga lokushisa. Yonke imidiya evamile efanelekile ingamanzi avamile anezinga lokushisa eliphakathi kuka-0 no-60 degrees Celsius. Lapho izinto ezinjengowoyela, ama-asidi aqinile nama-alkali, amazinga okushisa aphezulu, nezinye izimo ezibolayo nezinombala oqinile zikhona, amalunga enjoloba anezinto zokusetshenziswa ezihambisanayo kufanele asetshenziswe esikhundleni sokulandela umoya ngobumpumputhe noma ukuwasebenzisa endaweni yonke.
5. Ukugcinwa okufika ngesikhathi futhi okufika ngesikhathi kanye nokugcinwa kwamalunga enjoloba kufanele kwenziwe. Isibonelo, ekusetshenzisweni noma ekugcinweni kwe-amalunga enjoloba, izinga lokushisa eliphezulu, izinhlobo ze-oxygen esebenzayo, uwoyela, ne-asidi eqinile nendawo yemvelo ye-alkali kufanele kugwenywe. Ngesikhathi esifanayo, kuyadingeka ukucabangela ngokugcwele inkinga ye-brittleness yezandla zenjoloba, ngakho-ke kuyadingeka ukwakha uhlaka lwe-shading lwamapayipi angaphandle noma omoya, futhi unqabele ukuchayeka elangeni, imvula, nokuguguleka komoya.
