Jonga, ukuba ucinga ukuba i-flange yensimbi yintsimbi nje ethe tyaba enemingxuma, sele usemva. Lujongano, ukuxhawulana okubalulekileyo phakathi kweenkqubo eziphantsi koxinzelelo, kwaye ukufumana ukubamba isandla kungalunganga kuthetha ukuvuza, ixesha lokuphumla, kwaye ngokungafihlisiyo, ukukhwaza okuninzi kwindawo. I-spec sheet ayithethi lonke ibali.
Izinto eziphathekayo Asiyontsimbi Nje
Ufumana umzobo obiza a intsimbi yentsimbi. Kulungile. Kodwa ngaba i-A105? A350 LF2? 304L? 316 Yenziwe okanye yaphoswa? Yifolokhwe yokuqala leyo endleleni. Ndizibonile iiprojekthi apho baodola iiflange zentsimbi yekhabhoni yegeneric kwinkonzo yobushushu obuphantsi, bazifumana zibubunkunkqele njengeglasi xa ubushushu behlile. Ibakala lezinto eziphathekayo liyalela yonke into-i-machinability, weldability, resistance resistance. Indawo efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye neminyaka yabo engama-30 ekujuleni nasekusebenzeni, baya kukufundisa oku. Ababoni nje ibhloko yentsimbi; babona indawo yokugqibela yokusebenza.
Iiflange ezakhiweyo ziyindlela yokuya kwingqibelelo yoxinzelelo oluphezulu, ukuhamba kweenkozo kunye nayo yonke loo nto. Kodwa kwiimilo eziyinkimbinkimbi, enye-off okanye i-alloys ezithile, ukuphosa kunendawo yayo. Kulapho ukungunda kweqokobhe okanye utyalo-mali kungena, apho i-QSY igxile khona. Ukuchaneka ukusuka kwinqanaba lokuphosa kugcina itoni yeeyure zomatshini kamva. Awuthengi nje iflange; uthenga indlela yokuvelisa.
Kwaye i-alloys ... i-nickel-based okanye i-cobalt-esekelwe kubushushu obugqithisileyo / ukubola? Ukutsiba kweendleko kuqatha, kodwa kunjalo ke nesiphumo sokusilela. Lubizo lomgwebo. Ngamanye amaxesha ulinganisa ngexabiso eliphantsi njenge-304, uvavanye iimeko, emva koko uzibophelele kwizinto ezingaqhelekanga. Asiyoncwadi yesifundo; lulawulo lomngcipheko olusebenzayo.
UMatshini: Apho Ukunyamezelana Kufika Kuyinyani
Ukuphosa okukrwada okanye ukubunjwa sisiqalo nje esingenanto. I CNC Machining kulapho iba licandelo elisebenzayo. Ukugqitywa kobuso (ubuso obuphakanyisiweyo, ubuso obuthe tyaba, umdibaniso wohlobo lwendandatho), umngxuma wesangqa sedayamitha yebholiti, ibholi-kulapho i-microns ibalulekile. Umkrwelo kumphezulu wokutywina? Leyo yindlela enokuthi ivuze. Ndikhumbula ibhetshi apho imingxunya yebholithi yagrunjwa ukuze icaciswe, kodwa umphezulu wokugqiba wawurhabaxa kakhulu. Igasket ayikwazanga kuvaleka kakuhle. Yadlula i-QA ephepheni, kodwa yasilela kwihlabathi lenene.
Uzinzo lweDimensional lukhulu, ngakumbi kwiiflange ezinobubanzi obukhulu. Umatshini wenza uxinzelelo. Ukuba awuyiphathi kakuhle i-clamping kunye nokusikwa ngokulandelelana, inxalenye inokujika emva kokuba iphumile ebhedini. Emva koko ukuthamba kwakho kuphelile. Bubugcisa obufana nenzululwazi. Ivenkile enzulu CNC Machining amava, njengokuba ungawafumana ekusebenzeni kwe-QSY, inokulungiswa kunye nolwazi lwenkqubo yokulawula oku. Abaqhubanga nje inkqubo; bafunda ingxelo yezinto ngexesha lokusika.
Emva koko kukho ukuthunga. Imingxunya ye-stud bolt okanye imingxuma ecofiweyo? Kwiindawo ezishukumayo eziphezulu, unokufuna ifom yentambo eyahlukileyo okanye into yokutshixa. Zezi nkcukacha zincinci, ezingathandekiyo ezahlula i-flange esebenza kwenye ebangela ukuvalwa.
Intloko yeFit-Up kunye neWeld
Apha kulapho ithiyori idibana netotshi yokuwelda. Nokuba ngoomatshini ngokugqibeleleyo intsimbi yentsimbi inokonakala ngexesha le-welding kumbhobho. Ukushisa kwangaphambili, ubushushu be-interpass, unyango lwe-post-weld heat (PWHT) -tsiba naliphi na inyathelo lezinto ezingalunganga, kwaye udale indawo ebuthathaka, enqabileyo echatshazelwa ngubushushu. Ndibone i-ASTM A182 F316 i-flange entle eqhekezayo njengekuki kuba i-welder ayizange ilandele inkqubo yebakala lombhobho ohambelanayo.
Umsantsa wokufaneleka ngomnye umbulali othuleyo. Umsantsa omkhulu kakhulu, kwaye ubeka intsimbi ye-weld kakhulu, oko kwandisa uxinzelelo lwe-shrinkage. Iqinile kakhulu, kwaye awukwazi ukufumana ukungena ngokufanelekileyo. Eyona nto ifanelekileyo ngumsantsa ongaguquguqukiyo, ojikeleze imela macala onke. Ukufezekisa oko kufuna ukulungiswa kokuphela kombhobho ukuba kuchaneke kanye njengomatshini weflange. Yinkqubo, hayi icandelo elizimeleyo.
Kwaye makhe sithethe malunga nentamo ye-weld versus slip-on. Intamo ye-Weld (WN) yomelele, ingcono ukusabalalisa uxinzelelo, kodwa ixabiso kwaye kunzima ukulungelelanisa. I-Slip-on (SO) ilula ukulingana, kodwa loo nto yangaphakathi ye-fillet weld yi-concentrator yoxinzelelo. Ukhetho alusoloko lucacile. Ngamanye amaxesha kwi-tight-budget, umgca wokusetyenziswa okungabalulekanga, i-slip-on ilungile ngokugqibeleleyo. Imalunga nokuthelekisa iflange kwinkonzo, hayi ukukhetha eyona ilungileyo.
Unyango loMphezulu kunye noMbuzo wokuMhlwa
Unayo iflange yakho eyenziwe ngoomatshini. Ngaba yenziwe? Hayi kufutshane. Kwintsimbi yekhabhoni, ukuyishiya ingenanto kukucela umhlwa. Into eqhelekileyo kukugalela idiphu eshushu. Kodwa nanku umgibe: ukwenza igalvanizing kunokubangela imiba enobungakanani kubuso bokunyamezelana. Ubukhulu be-zinc layer buyahluka. Ndikhe ndabona iimeko apho i-flange efakwe igalvanized ayinakuhlangana ngokufanelekileyo nelinye icandelo ngenxa yokuba umphezulu wokutywina wawungasekho tyaba. Ngamanye amaxesha kuya kufuneka ugqume ubuso obubalulekileyo okanye uchaze enye i-coating efana nephosphate okanye ipeyinti.
Kwiiflange zentsimbi engatyiwayo, usenokucinga ukuba ukhuselekile. Kodwa ukuba zenziwe ngoomatshini kunye nezixhobo ze-carbon steel kwivenkile ephethe i-carbon steel, unobungozi bokungcoliswa kwekhabhoni. Oko kubulala ukuxhathisa umhlwa. Umgca wevenkile ozinikeleyo okanye iiprothokholi zokucoca ngokungqongqo zibalulekile. Yiyo loo nto ukwahlulwa kwezinto kwizinto eziluncedo. Inkampani ephethe ii-alloys ezahlukeneyo, njenge-alloys ezikhethekileyo i-QSY esebenza nazo, idinga ulawulo olungqongqo ukunqanda oku kungcoliseka.
Emva koko kukho i-passivation ye-stainless-ukususa i-iron simahla kumphezulu. Yibhafu yeekhemikhali, ilula ngombono. Kodwa ukuba ayenziwanga ngokucokisekileyo okanye ihlanjululwe ngokufanelekileyo, ushiywe nomphezulu othanda ukuba nomhlwa kunokuba wawuqala. Linyathelo lokugqiba ongenakho ukulihlawula ngexabiso eliphantsi.
Umgibe oLungileyo owaneleyo kunye nokuThola
Uxinzelelo lokunciphisa iindleko luhlala luhleli. Uya kufumana iikowuti zeeflange eziliqhezu lexabiso kumthengisi omtsha. Umzobo ukhangeleka ngokufanayo. Isiqinisekiso sezinto eziphathekayo sinokuthetha into enye. Kodwa usathana ukwinkqubo yolawulo. Ngaba unyango lobushushu lwenziwe ngokufanelekileyo? Ngaba ikhemistri yokunyibilika kumda omde womda obekiweyo? Uhlala ungazi de kusilela.
Ukwakha ubudlelwane kunye nomvelisi olawula inkqubo ukusuka kwinyibilika ukuya kumatshini kubaluleke kakhulu. Ukuba kukho ingxaki nge-porosity yokuphosa, banokuyilandela emva kwiqondo lokushisa lokugalela okanye ukungunda. Ukuba idimension yomatshini icinyiwe, banokujonga izixhobo zokunxiba izixhobo. Oko kulandeleka yinto oyihlawulayo. Ayisiyomveliso nje; yimbali ebhaliweyo. Kwingcali eqhuba ixesha elide efana QSY, ukuba ulawulo lwenkqubo ngumqolo wabo. Isingeniso sabo sithi bebekuyo ngaphezulu kweminyaka engama-30-oko kuthetha ukuba babonile kwaye balungisa lonke uhlobo lwesiphene sokwenza onokucinga.
Ekugqibeleni, musa ukungayihoyi ukupakishwa kunye nokuthunyelwa. Ndifumene iiflange ezinemigangatho etywiniweyo etywiniweyo kuba beziphoswe nje kwikhreyithi yomthi ngaphandle kokuvaleka kakuhle. Imayile yokugqibela ibalulekile. Umthengisi olungileyo uyaqonda ukuba icandelo alihanjiswanga de libe sezandleni zakho, lilungele ukufakwa, hayi nje xa lishiya idokhi yabo.
Ngoko ke, a intsimbi yentsimbi. Kubonakala kulula. Kodwa nganye imele uluhlu lwezigqibo-izinto eziphathekayo, inkqubo, umatshini, ukugqiba-kunye nekhefu kulo naliphi na ikhonkco elibonisa kwisiza, kungekhona eofisini. Injongo asikokugqibelela; kuqikelelwa, ukusebenza okuthembekileyo. Kwaye oko kuvela kuphela ekuyiphatheni njengojongano oluchanekileyo, hayi into yorhwebo.
