Kenyelletso ea mantlha ea flange
Li-pipe flanges le li-gaskets le li-fasteners ka kakaretso li bitsoa manonyeletso a flange.
Kopo:
Flange joint ke mofuta oa motsoako o sebelisoang haholo ho moralo oa boenjiniere.Ke karolo ea bohlokoa ea moralo oa liphaephe, lisebelisoa tsa lipeipi le li-valve, hape ke karolo ea bohlokoa ea lisebelisoa le likarolo tsa lisebelisoa (joalo ka mokoti, gauge ea seea-le-moea, joalo-joalo).Ntle le moo, manonyeletso a flange a atisa ho sebelisoa lithutong tse ling, joalo ka libopi tsa indasteri, boenjiniere ba mocheso, phepelo ea metsi le drainage, ho futhumatsa le moea, taolo ea othomathike, jj.
Sebopeho sa thepa:
Tšepe ea forged, WCB carbon steel, stainless steel, 316L, 316, 304L, 304, 321, chrome-molybdenum steel, chrome-molybdenum-vanadium steel, molybdenum titanium, rabara lening, fluorine linening.
Sehlopha:
Flat welding flange, neck flange, butt welding flange, ring e kopanyang flange, socket flange, le poleiti e foufetseng, joalo-joalo.
Tekanyetso ea tsamaiso:
Ho na le lihlopha tsa GB (tekanyetso ea naha), letoto la JB (lefapha la mechine), letoto la HG (lefapha la lik'hemik'hale), ASME B16.5 (tekanyetso ea Amerika), BS4504 (tekanyetso ea Brithani), DIN (tekanyetso ea Sejeremane), JIS (Tekanyetso ea Japane).
Sistimi e tloaelehileng ea liphaephe tsa machaba:
Ho na le maemo a mabeli a ka sehloohong a machaba a liphaephe tsa liphaephe, e leng tsamaiso ea liphaephe tsa Europe tse emeloa ke DIN ea Jeremane (ho kenyeletsoa le mehleng ea mehleng ea Soviet Union) le tsamaiso ea liphaephe tsa Amerika tse emetsoeng ke phala ea Amerika ea ANSI.
1. Plate mofuta bataletseng tjheseletsa flange
molemo:
Ho bonolo ho fumana thepa, e bonolo ho e etsa, e theko e tlase ebile e sebelisoa haholo.
Mefokolo:
Ka lebaka la ho tiea ha eona, ha ea lokela ho sebelisoa lits'ebetsong tsa liphaephe tsa lik'hemik'hale tse nang le litlhoko tsa phepelo le tlhoko, ho chesa, ho phatloha le tekanyo e phahameng ea vacuum, le maemong a kotsi haholo.
Mofuta oa bokaholimo ba ho tiisa o na le bokaholimo bo bataletseng le bo bokaholimo.
2. Flat welding flange ka molala
The slip-on welding flange e nang le molala ke ea tsamaiso ea maemo a naha a tloaelehileng.Ke mofuta o mong oa flange e tloaelehileng ea naha (eo hape e tsejoang e le GB flange) le e 'ngoe ea li-flange tse sebelisoang hangata lisebelisoa kapa liphaephe.
molemo:
Ho kenya setšeng ho loketse, 'me mokhoa oa ho cheselletsa seam rubbing o ka tloheloa
Mefokolo:
Bophahamo ba molala oa slip-on welding flange e nang le molala bo tlase, e leng ho ntlafatsang ho tiea le ho jara bokhoni ba flange.Ha ho bapisoa le butt tjheseletsa flange, mosebetsi oa tjheseletsa o moholo, tshebediso ya tjheseletsa molamu o phahame, 'me e ke ke mamella mocheso o phahameng le khatello e phahameng, ho khumama khafetsa le ho feto-fetoha ha mocheso.
3. Molala butt welding flange
Mefuta e ka holimo ea tiiso ea "neck butt welding" flange e kenyelletsa:
RF, FM, M, T, G, FF.
molemo:
Khokahano ha e bonolo ho holofala, phello ea ho tiisa e ntle, 'me e sebelisoa haholo.E loketse liphaephe tse nang le ho feto-fetoha ho hoholo ha mocheso kapa khatello, mocheso o phahameng, khatello e phahameng le mocheso o tlaase, hape bakeng sa liphaephe tse tsamaisang mecha ea litaba e theko e boima, mecha ea phatlalatso e tukang le e phatlohang, le likhase tse chefo.
Mefokolo:
The neck butt-welding flange e ngata, e ngata, e theko e boima, mme ho thata ho kenya le ho fumana sebaka.Ka hona, ho bonolo ho thula nakong ea lipalangoang.
4. Socket welding flange
Socket welding flangeke flange e cheselitsoeng ka phala ea tšepe ka lehlakoreng le leng 'me e tlameletsoe ka lehlakoreng le leng.
Mofuta oa bokaholimo ba tiiso:
Sefahleho se phahamisitsoeng (RF), sefahleho sa concave le convex (MFM), sefahleho sa tenon le groove (TG), sefahleho se kopaneng sa lesale (RJ)
Sebaka sa ts'ebeliso:
Boiler le sejana sa khatello, peterole, lik'hemik'hale, kaho ea likepe, meriana, metallurgy, mechini, ho hatakela lijo tsa setsoe le liindasteri tse ling.
E sebelisoa hangata liphaepheng tse nang le PN ≤ 10.0MPa le DN ≤ 40.
5. Flange e nang le likhoele
Leqhubu le nang le khoele ke lesela le sa cheseheleng, le sebetsanang le lesoba le ka hare la lesela hore e be khoele ea liphaephe ebe e hokahana le phaephe e khoeleng.
molemo:
Ha ho bapisoa le flange ea welding e bataletseng kapa butt welding flange,flange e khoelee na le litšobotsi tsa ho kenya le tlhokomelo e bonolo, 'me e ka sebelisoa liphaepheng tse ling tse sa lumelloeng ho chesetsoa setšeng.Alloy steel flange e na le matla a lekaneng, empa ha ho bonolo ho tjheseletsa, kapa ts'ebetso ea welding ha e ntle, flange e nang le likhoele le eona e ka khethoa.
Mefokolo:
Ha mocheso oa liphaephe o fetoha haholo kapa mocheso o phahame ho feta 260 ℃ 'me o le ka tlase ho -45 ℃, ho kgothaletswa hore o se ke wa sebelisa flange e nang le khoele ho qoba ho lutla.
6. Flange e foufetseng
E boetse e tsejoa e le sekoaelo sa flange le poleiti e sa boneng.Ke flange e se nang masoba bohareng bakeng sa ho koala phala ea phala.
Ts'ebetso e ts'oana le ea hlooho e cheselitsoeng le sekoaelo sa phala e kolobisitsoeng, ntle le moofoufetseng flangele threaded pipe cap, e ka tlosoa ka nako efe kapa efe, athe welded hlooho e ke ke.
Bokaholimo ba sekoaelo sa Flange:
Sefahleho se bataletseng (FF), sefahleho se phahamisitsoeng (RF), sefahleho sa concave le convex (MFM), sefahleho sa tenon le groove (TG), sefahleho se kopaneng sa lesale (RJ)
