Tarisa, kana iwe uchifunga kuti simbi flange ingori mhete ine maburi, iwe watove kumashure. Ndiwo maratidziro, kubata ruoko kwakasimba pakati pemasystem ari pasi pekumanikidzwa, uye kuita kuti kubata maoko zvisizvo kunoreva kuvuza, nguva yekudzikira, uye kutaura chokwadi, kudanidzira kwakawanda panzvimbo. Iyo spec sheet haitauri nyaya yese.
Zvinhu Hazvisi Simbi Chete
Iwe unowana kudhirowa kunodaidza a simbi flange. Okay. Asi iyo A105? A350 LF2? 304L? 316? Forged or cast? Ndiyo forogo yekutanga mumugwagwa. Ndakaona mapurojekiti kwavakaodha generic kabhoni simbi maflange ebasa rekudzikira, ndokuzongoona ari brittle segirazi kana tembiricha yadzikira. Iyo yemhando giredhi inoraira zvese- machinability, weldability, corrosion resistance. Nzvimbo yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakore avo makumi matatu ekukandira nekugadzira michina, vaizoroverera izvi mauri. Havangooni simbi; vanoona mamiriro ekupedzisira ekushanda.
Forged flanges ndiyo yekuenda kune yakakwirira-kumanikidza kutendeseka, kuyerera kwezviyo uye zvese izvo. Asi kune yakaoma, imwe-kure maumbirwo kana chaiwo alloys, kukanda kune nzvimbo yayo. Ndipo panopinda shell mold kana investing casting, iyo QSY inonyanya kushanda nayo. Iyo chaiyo kubva padanho rekukanda inochengetedza toni yemaawa machining gare gare. Iwe hausi kungotenga flange; uri kutenga nzira yekugadzira.
Uye ma alloys ... nickel-based kana cobalt-yakavakirwa pakupisa kwakanyanya / kuora? Kusvetuka kwemutengo kwakaoma, asi ndizvo zvakaitawo mhedzisiro yekutadza. Kudanwa kwekutongwa. Dzimwe nguva iwe unofananidzira neyakachipa isina tsvina senge 304, edza mamiriro, wobva wazvipira kune ekunze zvinhu. Harisi bhuku; ibasa rekuchengetedza njodzi.
Machining: Ikoko Kushivirira Kunowana Kwechokwadi
Iyo mbishi yekukanda kana kuforoma ndiyo yekutanga isina chinhu. The CNC machining ndipo painova chikamu chekushanda. Kupera kwechiso (chiso chakasimudzwa, chiso chakati sandara, ring-type joint), bhaudhi gomba denderedzwa dhayamita, bhomba-apa ndipo pakakosha mamicrons. Kukwenya pamusoro pekuisa chisimbiso? Ndiyo nzira inogona kubuda. Ini ndinorangarira batch apo maburi ebhaudhi akaboorwa kuti ataure, asi kupedzisa kwepamusoro kwaive kwakanyanyisa. Iyo gasket haina kukwanisa kunama zvakanaka. Yakapfuura QA papepa, asi yakakundikana munyika chaiyo.
Dimensional kugadzikana kwakakura, kunyanya kune yakakura-diameter flanges. Machining anokonzera kushushikana. Kana iwe ukasabata iyo clamping uye kucheka kutevedzana zvakanaka, chikamu chinogona kuputika mushure mekunge chabva pamubhedha. Ipapo flatness yako yapera. Hunyanzvi hwakafanana nesainzi. Chitoro chine kudzika CNC machining ruzivo, sezvaungawana pakushanda kweQSY, ine kugadzirisa uye kugadzirisa ruzivo kudzora izvi. Havasi kungomhanyisa chirongwa; vari kuverenga mhinduro yezvinyorwa panguva yekucheka.
Zvadaro pane threading. Stud bolt maburi kana maburi akatepwa? Kunzvimbo dzekuzunguzika kwepamusoro, ungangoda fomu reshinda rakasiyana kana chinhu chekukiya. Aya ndiwo madiki, asina kunaka anoparadzanisa flange inoshanda kubva kune inokonzeresa kuvharika.
The Fit-Up uye Weld Headache
Apa ndipo panosangana dzidziso netochi yewelding. Kunyange akagadzirwa zvakakwana simbi flange inogona kuparadzwa panguva welding kune pombi. Pre-heat, interpass tembiricha, post-weld heat treatment (PWHT) - svetuka chero nhanho yechinhu chisina kunaka, uye wagadzira isina kusimba, isina brittle inopisa-inokanganisa nzvimbo. Ndakaona yakanaka ASTM A182 F316 flange ichitsemuka kunge cookie nekuti welder haana kutevedzera maitiro ekufananidza pombi giredhi.
Fit-up gap imwe mhondi yakanyarara. Yakakura gap, uye iwe uri kuisa yakawandisa weld simbi, izvo zvinowedzera shrinkage kushushikana. Yakanyanya kusimba, uye haugone kuwana kwakaringana kupinda. Iyo yakanaka ndeye inowirirana, banga-kumucheto gap kumativi ose. Kuwana izvo zvinoda kuti pombi yekupedzisira gadziriso ive chaiyoiyo seyakagadzirwa flange machining. Ihurongwa, kwete chikamu chega.
Uye ngatitaure nezve weld neck versus slip-on. Weld neck (WN) yakasimba, iri nani pakugovera kushushikana, asi inodhura uye yakaoma kurongedza. Slip-on (SO) iri nyore kukwana, asi iyo yemukati fillet weld inokonzeresa kushushikana. Sarudzo haisi nguva dzose yakajeka-yakatemwa. Dzimwe nguva pane yakaomesesa-bhajeti, isiri-yakakosha utility mutsara, slip-on yakanaka chaizvo. Izvo ndezvekufananidza flange kune sevhisi, kwete kungotora yakanakisa.
Kurapa Kwepamusoro & Mubvunzo Wekuora
Iwe une flange yako yakagadzirwa. Zvaitwa here? Kwete kana pedyo. Kusimbi yekabhoni, kuisiya isina chinhu kukumbira ngura. A common spec is hot-dip galvanizing. Asi heino musungo: galvanizing inogona kukonzera nyaya dzakadzika pane zviso zvekushivirira. Ukobvu hwe zinc hunosiyana. Ndakaona zviitiko apo galvanized flange yaisazobatana nemazvo nechimwe chikamu nekuti yekuisa chisimbiso yaive isisipo. Dzimwe nguva unofanirwa kuvhara zviso zvakakomba kana kutsanangura rakasiyana coating senge phosphate kana pendi.
Kune simbi isina simbi flanges, unogona kufunga kuti wakachengeteka. Asi kana vakagadzirwa nekabhoni simbi maturusi muchitoro chinobatawo kabhoni simbi, unoisa panjodzi yekusvibiswa kwekabhoni. Izvozvo zvinouraya corrosion resistance. Mutsetse wechitoro wakatsaurirwa kana maprotocol ekuchenesa akakosha. Ichi ndicho chikonzero kupatsanurwa kwezvinhu mune imwe nzvimbo kuchikosha. Kambani inobata ma alloys akasiyana, seakakosha alloys QSY inoshanda nawo, inoda kudzora kwakasimba kudzivirira uku kusvibiswa.
Zvadaro pane passivation ye-stainless-kubvisa simbi yemahara kubva pamusoro. Ikemikari yekugeza, iri nyore mupfungwa. Asi kana isina kunyatsoitwa kana kugezeswa zvakanaka, unosara uine nzvimbo inenge ichiita ngura kupfuura pawakatanga. Idanho rekupedzisa rausingakwanise kutenga zvakachipa.
Iyo Yakanaka Yakakwana Musungo uye Sourcing
Dzvinyiriro yekuderedza mari inogara iripo. Iwe uchawana makotesheni emaflange ari chidimbu chemutengo kubva kune mutsva mutengesi. Mufananidzo unotaridzika zvakafanana. Material cert angatotaura zvimwe chetezvo. Asi dhiyabhorosi ndiye ari kutonga. Kurapa kwekupisa kwakaitwa zvakanaka here? Iyo chemistry yekunyungudika iri pamucheto wepamusoro weiyo spec muganho? Kazhinji hauzivi kusvika zvakundikana.
Kuvaka hukama nemugadziri anodzora maitiro kubva pakunyunguduka kuenda kumachina kwakakosha. Kana paine dambudziko nekukanda porosity, vanogona kuitsvaga vachidzokera kune tembiricha yekudira kana mold. Kana chiyero chemuchina chakadzimwa, vanogona kutarisa matanda ekushandisa. Iyo traceability ndiyo yauri kubhadhara. Haisi chigadzirwa chete; inhoroondo yakanyorwa. Kumazvikokota anomhanya kwenguva refu se QSY, that process control ndiwo musana wavo. Nhanganyaya yavo inoti vagara pairi kweanopfuura makore makumi matatu-zvinoreva kuti vangangoona nekugadzirisa marudzi ese ekugadzira kukanganisa kwaungafungidzira.
Pakupedzisira, usakanganwa kurongedza uye kutumira. Ndakagamuchira maflange ane nicked sealing surfaces nekuti aingokandwa mu crate yemapuranga pasina kuvharika chaiko. Maira yekupedzisira inokosha. Mutengesi akanaka anonzwisisa kuti chikamu hachiunzwa kusvika chave mumaoko ako, chagadzirira kuisirwa, kwete chete kana chasiya doko ravo.
Saka, a simbi flange. Zvinoita sezviri nyore. Asi imwe neimwe inomiririra cheni yezvisarudzo-zvinhu, maitiro, machining, kupedzisa-uye kuzorora mune chero chinongedzo chinoratidza pane saiti, kwete muhofisi. Chinangwa hachisi kukwana; zviri kufanotaurwa, kuita kwakavimbika. Uye izvo zvinongouya kubva mukuibata seyakajeka-engineered interface, kwete chinhu.
