1. Izinhlobo ezihlukene zokushisela:
Slip On Flanges: i-fillet weld isetshenziselwa ukushisela phakathi kwepayipi le-flange ne-flange.
I-Weld Neck Flanges: i-seam yokushisela phakathi kwe-flange nepayipi i-weld eyindilinga.
2. Izinto ezihlukile:
I-Slip On Flanges yenziwe ngomshini ngepuleti lensimbi elivamile elinogqinsi oluhlangabezana nezidingo.
Ama-Weld Neck Flanges asetshenziswa kakhulu ngensimbi eyenziwe ngomgunyathi.
3. Izingcindezi ezihlukile:
Ingcindezi yokulinganisa ye-Slip On Flanges: 0.6 — 4.0MPa
Ukucindezela okulinganiselwe kwe-Weld Neck Flanges : 1-25MPa
4.Izakhiwo ezehlukene
I-Slip On Flanges: isho i-flange enweba amapayipi ensimbi, ukufakwa kwamapayipi, njll. ku-flange futhi ixhumeke ngezinto zokusebenza noma amapayipi ngokusebenzisa ama-weld we-fillet.
I-Weld Neck Flanges: i-flange enentamo kanye nokuguqulwa kwepayipi, exhunywe nepayipi ngokushisela izinqe.
5. Ububanzi besicelo:
I-Slip On Flanges : iyasebenza ekuxhumekeni kwamapayipi ensimbi ngokucindezela okuzisholo okungeqile ku-2.5MPa. Indawo yokuvala ye-flange ingenziwa ibe izinhlobo ezintathu: uhlobo olubushelelezi, uhlobo lwe-concave convex kanye nohlobo lwe-mortise. Ukusetshenziswa kwe-flange ebushelelezi yiyona enkulu kunazo zonke Isetshenziswa kakhulu ezimweni ezimaphakathi ezimaphakathi, njengomoya ocindezelwe ophansi ongahlanjululwanga nomoya ocindezelweyo ocindezelweyo kanye namanzi ajikelezayo.
I-Weld Neck Flanges : isetshenziselwa ukushisela izinqe zamaflange namapayipi. Ukwakheka kwayo kunengqondo, amandla nokuqina kwayo kukhulu, ikwazi ukumelana nezinga lokushisa eliphezulu nokucindezela okukhulu, ukugoba okuphindaphindiwe kanye nokuguquguquka kwezinga lokushisa, futhi ukubekwa kwayo uphawu kunokwethenjelwa. I-flange yokushisela izinqe zentanyeni enengcindezi encane engu-1.0~16.0MPa isebenzisa indawo evalekile yokuvala i-convex.
I-flange ye-welding flat ingaxhunyaniswa kuphela nepayipi futhi ayikwazi ukuxhunyaniswa ngokuqondile nepayipi ye-welding ye-butt; Ama-flange we-butt-welding ngokuvamile angaxhunywa ngokuqondile kukho konke ukufakwa kwamapayipi okushisela izinqe (kuhlanganise nezindololwane, ama-tee, amapayipi anobubanzi obuhlukene, njll.), futhi kunjalo, amapayipi.
Ukuqina kwe-neck butt welding flange kukhulu kunaleyo ye-flange ye-welding yentamo eyisicaba, futhi amandla okushisela izinqe aphakeme kunalawo e-flange yokushisela eyisicaba, ngakho akulula ukuvuza.
I-neck flat welding flange kanye ne-neck butt welding flange ayikwazi ukushintshwa ngokuthanda kwakho. Mayelana nokukhiqiza, i-neck flat welding flange (SO flange) ine-warpage enkulu yangaphakathi, isisindo esincane kanye nezindleko eziphansi. Ngaphezu kwalokho, i-flange ye-butt-welding yentamo enobubanzi obujwayelekile obungaphezu kuka-250 mm (WN isifinyezo se-WELDINGCHECK) idinga ukuhlolwa, ngakho izindleko ziphansi.
I-flat welding enentamo isetshenziswa kakhulu emishinini ye-petroleum engenisiwe, efana ne-American standard S0. Ama-butt-welding flange asetshenziselwa imidiya eyingozi kakhulu.
I-butt-welding flange ibhekisela kububanzi bepayipi nobukhulu bodonga bokuphela kokuxhuma, okufana nepayipi elizoshiselwa, njengoba nje amapayipi amabili eshiselwe.
I-flange yokushisela i-flange iyipulatifomu ye-concave, imbobo yayo yangaphakathi inkulu kancane kunobubanzi obungaphandle bepayipi, futhi ipayipi ifakwe ekushiseleleni kwangaphakathi.
I-flat welding kanye ne-butt welding ibhekisela ezindleleni zokushisela ze-flange nokuxhuma kwamapayipi. Lapho welding flat Welding flange, eyodwa kuphela Welding ohlangothini oludingekayo, futhi asikho isidingo ukushisela ipayipi kanye flange uxhumano. I-welding kanye nokufakwa kwe-welding flange idinga ukushiswa ezinhlangothini zombili ze-flange. Ngakho-ke, i-flange ye-welding flat ngokuvamile isetshenziselwa ukucindezela okuphansi kanye namapayipi okucindezela okuphakathi, futhi i-butt welding flange isetshenziselwa uxhumano lwamapayipi okucindezela okuphakathi nendawo. I-butt welding flange ngokuvamile okungenani i-PN2. 5 MPa, sebenzisa i-butt welding ukunciphisa ukugxila kwengcindezi. Ngokuvamile, i-butt welding flange ibizwa nangokuthi i-high neck flange ene-neck flange. Ngakho-ke, izindleko zokufaka, izindleko zabasebenzi kanye nezindleko eziwusizo ze-welding flange ziphezulu, ngoba kunenqubo eyodwa kuphela ye-welding flange.
