Iingqiniba zentsimbingamacandelo aphambili kwiinkqubo ezahlukeneyo zemibhobho, ebonelela ngokuguquguquka kunye nokuqina ekulawuleni ukuhamba kolwelo kunye neegesi. Ezi ngqiniba zisetyenziswa kakhulu kwi-petrochemical, i-oyile kunye negesi, ukulungiswa kokutya, amayeza kunye namanye amashishini. Nangona kunjalo, ukwenzela ukuba kuqinisekiswe umgangatho kunye nokuthembeka kwee-elbows zensimbi ezingenasici, kubalulekile ukuqonda imigangatho elawula ukwenziwa nokusetyenziswa kwazo.
Imigangatho ye-elbows yensimbi engenasici igxininiswe ngokukodwa ngokucaciswa kwezinto eziphathekayo, imilinganiselo kunye neenkqubo zokuvelisa. Owona mgangatho ukhankanyiweyo ngokuqhelekileyo weengqiniba zentsimbi ngumgangatho we-ASME B16.9. Lo mgangatho uchaza imilinganiselo, ukunyamezela kunye nezixhobo zee-elbows zensimbi ezingenasici ezisetyenziselwa uxinzelelo oluphezulu kunye nezicelo zokushisa okuphezulu.
Ngokwemigangatho ye-ASME B16.9, ii-elbows zensimbi ezingenasici zifumaneka ngobukhulu obuhlukeneyo ukusuka kwi-1/2 intshi ukuya kwi-intshi ye-48, kunye nee-angles ezahlukeneyo ezifana ne-45 degrees, i-90 degrees, kunye ne-180 degrees. Umgangatho ukwachaza ukunyamezela okuvumelekileyo kwimilinganiselo yengqiniba, ukuqinisekisa ukuba bayahlangabezana neenkcukacha ezifunekayo kulwakhiwo olungenamthungo noludityanisiweyo.
Ukongeza kwimigangatho ye-ASME B16.9, ii-elbows zensimbi ezingenasici zingenziwa kwaye zivavanywe kwezinye imigangatho yamazwe ngamazwe njenge-ASTM, i-DIN, kunye ne-JIS, kuxhomekeke kwiimfuno ezithile zesicelo kunye nendawo yeprojekthi.
Ngokubhekiselele kwizinto eziphathekayo, ii-elbows zensimbi ezingenasici zihlala zenziwe nge-austeniticyenziwe ngentsimbi eshayinayoamabanga afana ne-304, 304L, 316 kunye ne-316L. La mabanga abonelela ngokumelana nokugqwesa okugqwesileyo, ukomelela okuphezulu kunye nokuwelda okulungileyo, okubenza bafanelekele uluhlu olubanzi lwezicelo zemizi-mveliso.
Inkqubo yokwenziwa kwee-elbows zensimbi engenasici nayo ilawulwa yimigangatho yokuqinisekisa umgangatho kunye nokunyaniseka kwemveliso yokugqibela. Iinkqubo ezifana ne-thermoforming, i-cold forming kunye ne-machining kufuneka ihambelane nemigangatho yokugcina iimpawu zomatshini kunye nokuchaneka kwe-dimensional ye-elbow.
Ngokumalunga novavanyo kunye nokuhlolwa, ii-elbows zensimbi ezingenasici kufuneka zibe neemvavanyo ezahlukeneyo ezingonakalisi kunye nezonakalisayo zokuqinisekisa umgangatho kunye nokusebenza kwazo. Ngokuxhomekeke kwimigangatho efanelekileyo, olu vavanyo lunokubandakanya ukuhlolwa okubonakalayo, ukuhlolwa kwe-dimensional, uvavanyo lokungena kwedayi, uvavanyo lwe-radiographic kunye novavanyo lwe-hydrostatic.
Kubalulekile ukuba abavelisi, ababoneleli kunye nabasebenzisi bokugqibela baqonde iimfuno ezisemgangathweni zee-elbows zensimbi ezingenasici ukuqinisekisa ukuba imveliso ihlangabezana nemigangatho efunekayo yomgangatho kunye nokhuseleko. Ukuthobela le migangatho akuqinisekisi kuphela ukuthembeka kunye nokusebenza kwe-elbow, kodwa kunceda ukuphucula ingqibelelo yonke yenkqubo yokubhobhoza apho i-elbow isetyenziswa khona.
Ukushwankathela, imigangatho yeengqiniba zentsimbi igubungela imiba eyahlukeneyo efana neenkcukacha zezinto eziphathekayo, imilinganiselo, iinkqubo zokuvelisa, kunye neemfuno zovavanyo. Ngokuqonda kunye nokuthobela le migangatho, abachaphazelekayo kumashishini banokuqinisekisa umgangatho, ukuthembeka kunye nokukhuseleka kwee-elbows zensimbi ezingenasici kwizicelo zabo. Ingaba yinkqubo ebalulekileyo kwisityalo sekhemikhali okanye isicelo sococeko kwishishini lokutya, imigangatho ye-elbow yensimbi engenasici idlala indima ebalulekileyo ekugcineni ukusebenza kakuhle kunye nokunyaniseka kwenkqubo yakho yokubhobhoza.
