Okokuqala, umthengi kufuneka acacise iinkcukacha kunye neemodeli zeiingqinibakufuneka bathenge, oko kukuthi, ububanzi bengqiniba, Kufuneka baqwalasele ukuba bakhethe i-elbow elinganayo okanye ukunciphisa i-elbow, kunye nokuqinisekisa imigangatho, amanqanaba oxinzelelo, okanye ubukhulu bodonga lwengqiniba.Okwesibini, izinto ze-elbows kufuneka ziqwalaselwe.Okwesibini, umba wokuthintela ukubola kufuneka uqwalaselwe, nokuba i-elbows ifuna ukupeyintwa okanye i-sandblasted.
1. Kutheni unikela ingqalelo kwizinto zengqiniba?
Ngeenjongo ezahlukeneyo, kuyimfuneko ukusebenzisa i-elbows ehambelanayo yezixhobo ezahlukeneyo ukuhambelana.Izinto eziqhelekileyo zingahlulwa zibeiingqiniba zentsimbikwayecarbon steel elbows.Ukwakhiwa kweekhemikhali eziqulethwe kwii-elbow zensimbi ezingenasici kuya kuthintela umphezulu we-elbow ukuba ungagqwala kunye nokubola ixesha elide.Esona sizathu siphambili sokumahluko kwayo kwi-carbon steel elbows ngumahluko kwizinto eziphathekayo.
I-elbow yensimbi engenasici yenziwa ngokunyathela kwimilo ejikelezayo ukusuka kwiphepha lezinto ezifanayo, ukudibanisa ama-halves amabini kunye kwaye emva koko uwadibanise.Emva kokuba ityhalwe ngaphakathi, iphinda ibunjwe kwakhona phantsi kokufudumala ukuqinisekisa ukuba i-diameter yangaphandle kunye nobukhulu bodonga lwengqiniba luhlangabezana neemfuno.Emva koko, ukudubula ukuchama kwenziwa ukuze kususwe ulusu lwe-oxide kwindawo engaphakathi yengqiniba efakela kunye nomphezulu ongaphandle wentloko egobayo, zozibini iziphelo zithambekele ukuwelda lula.
2. Kutheni unikela ingqalelo kubungakanani bengqiniba?
Ingqiniba eqhelekileyo ngumphinda-phinde onesiqingatha ubukhulu, imelwe ngu-R=1.5D.Nangona kunjalo, kuyo yonke imarike yokufakwa kombhobho, uninzi lokubumba imveliso luyi-1.25D, eyi-gap ye-0.25D.Izinto ezisetyenziselwa ukutyhala iingqiniba, oko kukuthi, imibhobho, inokonga kakhulu, nto leyo ekhokelela kumohluko omkhulu wobunzima kunye nokwahluka kwexabiso.Oku kwaziwa njengeengqiniba ezingekho mgangathweni, ezimfutshane kakhulu kuneengqiniba eziqhelekileyo.Iimodeli ezingafanelekanga zeengqiniba nazo zinokubangela imiba engafanelekanga ngexesha lokusetyenziswa, okukhokelela ekungahambelani kwezixhobo.
3. Kutheni le nto kufuneka siqonde ukuba iingqiniba zokulwa nomhlwa ziyafuneka?
I-elbow ye-Anticorrosive ibhekisela kwi-elbow esetyenzisiweyo kwaye iphathwe nge-teknoloji ye-anti-corrosion, enokuthi ithintele ngokufanelekileyo okanye icothise ukwenzeka kweekhemikhali zokwenziwa kweekhemikhali ngexesha lokuthutha kunye nokusetyenziswa, okukhokelela kwi-corrosion ye-elbow.Iindlela eziqhelekileyo ziquka ukusebenzisa i-non-toxic kunye ne-odorless anti-corrosion coatings kunyango, kunye nokusebenzisa umgubo we-epoxy kumphezulu weengqiniba usebenzisa ukutshiza kwe-electrostatic.I-Anticorrosive elbows ayinyangeki kuphela kwi-corrosion, kodwa ikwazi ukumelana nokugoba, ubushushu obuphezulu, impembelelo, ukoma okukhawulezayo, ukuxhathisa kwe-alkali, ukunamathela okulungileyo, ukuxhathisa kwe-asidi, ukuxhathisa ityuwa, kunye nokuthamba okulungileyo.Zilungele imimandla eyahlukeneyo efana nerhasi yendalo, ukucocwa kogutyulo, i-petroleum, kunye namanzi ompompo.Iingqiniba ze-Anticorrosive zisetyenziswa ngokubanzi kwiimeko ezithile ezikhethekileyo.
4. Kutheni unikela ingqalelo kudonga lwengqiniba?
Ukuthatha ingqiniba kwimveliso yerhasi yendalo kunye nokusebenza njengomzekelo, ingqiniba yokuqokelelwa kwerhasi yendalo kunye nombhobho wothutho uqhelene nokuncipha ngokukhawuleza phantsi kokhukuliseko lokutya kunye nokhukuliseko, oluchaphazela ukhuseleko lomsebenzi wombhobho.Ngoko ke, kuyimfuneko ukulinganisa ubukhulu bodonga kwi-elbow yombhobho.Ukusetyenziswa kwetekhnoloji yokulinganisa ubukhulu be-ultrasonic kuvavanyo lwesampulu yobukhulu bodonga kwindawo yengqiniba yokuqokelelwa kwerhasi yendalo kunye nothungelwano lwemibhobho yothutho luyasetyenziswa.
