EN 1092-1 Ukuwelda iNtamo yeFlange yentsimbi engatyiwayo yeCarbon

Idatha yeMveliso

Intshayelelo yeMveliso

Umgangatho we-EN1092-1 ngomnye wemigangatho equlunqwe ngokudibeneyo yi-European International Organisation for Standardization (ISO) kunye ne-European Organisation for Standardization (CEN), echaza ukuyila, ubungakanani kunye neemfuno zobugcisa zeeflange kunye nezixhobo zeflange.Phakathi kwabo, i-neck butt welding flange yenye yeentlobo eziqhelekileyo ze-flange.

I-weld neck flange yingqukuvaiflangeenentamo ephumayo embindini.Intamo yinxalenye esetyenziselwa ukudibanisa i-flange kunye nombhobho okanye izixhobo, kwaye i-flange igxininiswe kumbhobho okanye izixhobo ngokudibanisa intamo.I-Weld neck flanges idla ngokwenziwa nge-carbon steel, i-stainless steel okanye i-alloy steel kwaye ifanelekile kuxinzelelo oluphezulu kunye nokushisa okuphezulu.

Umgangatho we-EN1092-1 uchaza ubungakanani kunye nenqanaba loxinzelelo lwe-flange yentamo edibeneyo ukuqinisekisa ukuba ukudibanisa kwayo kunye nombhobho okanye izixhobo zingenziwa phantsi kweemeko ezikhuselekileyo nezithembekileyo.Umgangatho ukwabandakanya izinto, ukuveliswa kunye neemfuno zokuvavanya iiflanges ukuqinisekisa ukuthotyelwa komgangatho ofanelekileyo kunye nemigangatho yokhuseleko.

Weld intamo flangeyindlela eqhelekileyo yokudibanisa i-flange, esetyenziswa ngokubanzi kwintsimi yezoshishino.Uyilo kunye nokuveliswa kwayo kufuneka kulandele imigangatho efanelekileyo kunye neenkcukacha zokuqinisekisa ukusebenza kwayo kakuhle kunye nokuthembeka.

Ubungakanani:
Ubungakanani obuqhelekileyo be-weld neck flanges uluhluukusuka kwi-DN15 ukuya kwi-DN2000.

Uxinzelelo:
Imilinganiselo yoxinzelelo oluqhelekileyo lwe-weld neck flanges luluhluukusuka kwi-PN2.5 ukuya kwi-PN100.

Ukongeza, umgangatho we-EN1092-1 uchaza iimfuno zobugcisa ezifana nobukhulu bomngxuma webholithi, ubuninzi, kunye ne-pitch ye-flange yentamo edibeneyo ukuqinisekisa ukuba ukudibanisa kwayo kunye nombhobho okanye izixhobo kunokwenziwa phantsi kweemeko ezikhuselekileyo nezithembekileyo.

Nangona kunjalo, kufuneka kuqatshelwe ukuba amazwe ahlukeneyo kunye nemimandla ingaba nemigangatho kunye neenkcukacha zabo, ngoko xa ukhetha i-neck butt welding flanges, kufuneka ubhekiselele kwimigangatho ehambelanayo kunye neenkcukacha ngokwemeko ethile.

I-advanteji:
I-1.I-neck butt welding flange inokusebenza kakuhle kokutywinwa kwaye ingasetyenziselwa ukudibaniswa kwemibhobho ngoxinzelelo oluphezulu, ubushushu obuphezulu okanye imidiya ebolileyo.
2.Ngenxa yobukho bentamo, i-neck butt welding flange inokumelana nemithwalo emikhulu kunye nemithwalo yempembelelo, kwaye inokumelana nokothuka okungcono.
I-3.I-weld neck flange ine-compact structure kwaye ayifuni kakhulu kwiingxaki zokuvuza.
I-4.I-neck butt welding flange inendlela yokudibanisa elula kwaye kulula ukuyifaka kunye nokuqhaqha.

Izinto ezingeloncedo:
I-1.Indleko yokuvelisa i-weld neck flange iphezulu kakhulu.
2.Njengoko ukuyila kunye nokuveliswa kwayo kufuneka kulandele ngokungqongqo imigangatho kunye nemimiselo, kukho ingxaki yokulawula umgangatho onzima kwinkqubo yokwenziwa kunye nokusetyenziswa.

Usetyenziso:
Iiflange ze-welding zentamo zifanelekile ukudibaniswa kwemibhobhokwiinkalo ezininzi, ngakumbi ezo zifuna uxinzelelo oluphezulu, ubushushu obuphezulu, i-corrosion, vibration kunye nezinye iimeko zokusebenza.Iindawo ezikhethekileyo zesicelo ziquka i-petroleum, ikhemikhali, amandla ombane, igesi yendalo, amayeza, ukutya, iphepha kunye namanye amashishini.

Ngamafutshane, i-neck butt welding flange yindlela ethembekileyo yokudibanisa umbhobho kunye nokusebenza kakuhle kokutywinwa kunye nokuxhathisa ukothuka.Ilungele ukudityaniswa koxinzelelo oluphezulu, ubushushu obuphezulu, kunye ne-corrosion medium pipeline.Ukulawula umgangatho.
