Hano hari ibifata bifata ibice hamwe, hanyuma hakabaho ibice byizerwa byiringirwa ahantu kunanirwa atari amahitamo.
ASTM A193 Icyiciro cya B7 sitidiyo iri mubyiciro bya kabiri.
Mu nganda zikora inganda, ibihingwa ngandurarugo, sisitemu yumurongo wumuvuduko hamwe nu mushinga wo kuvugurura ibikoresho, izi sitidiyo ziratoranywa buri gihe kubera ko abajenjeri bakeneye igisubizo cyihuse gishobora kuguma gihamye mugihe cyumuvuduko, kunyeganyega hamwe nubushyuhe bwubushyuhe burigihe.
Igituma sitidiyo ya B7 itandukanye ntabwo ari umubiri wuzuye wuzuye ubona ku ishusho.
Agaciro nyako kari mubikoresho no kuvura ubushyuhe inyuma yacyo.
Yakozwe muri chromium - molybdenum alloy ibyuma kandi ikorerwa kuzimya no gushyuha, ibi byuma byubatswe byubatswe mubisabwa aho ibyuma bisanzwe bya karuboni bifatanyirijwe hamwe ntibifatwa nkibyemewe.
Ku matsinda yo gufata neza ibihingwa, cyane cyane abakorana na sisitemu ya flange, valve hamwe nigifuniko cyubwato, sitidiyo ya B7 ikunze gufatwa nkibintu bisanzwe byimigabane kubera ko byagaragaye ko byizewe muri serivisi.
Ku munsi - kugeza - ibikorwa byo gutunganya umunsi, bikunze gushyirwaho mubice bya flange aho guhora preload hamwe nigitutu cya kashe ari ngombwa.
Ndetse igihombo gito mumbaraga zifatika zirashobora kugira ingaruka kumikorere ya gasketi, niyo mpamvu abashakashatsi b'imishinga bakunze kwerekana B7 aho kuba inkoni rusange.
Ibi ni ukuri cyane mubikoresho bya peteroli na gaze aho idirishya ryo gufata neza riba rito cyane.
Ubuso bwirabura burangiye bwerekanwe mumashusho nicyiciro cyambere cyo kurangiza inganda abaguzi benshi bahita bifatanya na B7 flange sitidiyo.
Biremewe cyane kubidukikije byo murugo, guteranya imashini hamwe no kubika ububiko.
Kubireba ikirere gikaze cyane cyane mubikomoka kuri peteroli ya chimique cyangwa ku nkunga ziva mu nyanja, kuzamura ibishishwa birashobora gutangwa ukurikije ibisabwa n'umushinga.
Kurenga ibikomoka kuri peteroli, twabonye ibyifuzo bikenerwa kubicuruzwa mugusana ibikorwa remezo no mumishinga yo kugarura imiterere.
Muri post - imirimo yo kubaka amakimbirane, uturere two gusana inganda hamwe n’ibyuma byihutirwa byashyizweho, abashoramari bakeneye sisitemu yo gufunga ishobora gushyirwaho vuba mugihe bagitanga ikizere cyubaka.
Ibikoresho bisanzwe bya Flange
| Ingano ya Flange | Ingano yo Kwiga | Umubare |
|---|---|---|
| 2" | 5/8 "× 90mm | 4 pc |
| 4" | 3/4 "× 120mm | 8 pc |
| 6" | 3/4 "× 140mm | 8 pc |
| 8" | 7/8 "× 160mm | 8 pc |
| 10" | 1 "× 180mm | 12 pc |
Aha niho umurongo wuzuye B7 sitidiyo iba ingirakamaro cyane.
Kuberako ibinyomoro bishobora guhindurwa mubwisanzure burebure bwurudodo rwuzuye, akenshi bikoreshwa mumashanyarazi yigihe gito, ibikoresho fatizo, ibikoresho bifasha ibikoresho hamwe no kubaka imirimo aho kwihanganira ibipimo kurubuga bigoye guhanura.
Ugereranije na bolts zisanzwe, zitanga byinshi guhinduka mugihe cyo guterana.
Kubashoramari ba EPC, iyi flexible ihinduranya mugihe gito cyo kwishyiriraho nibibazo bike byo gusimburwa.
Urebye kubigura, abaguzi mubikorwa bya peteroli na chimique mubisanzwe basaba sitidiyo ya B7 hamwe na ASTM A194 Icyiciro cya 2H.
Ihuriro rikomeje kuba kimwe mubimenyerewe cyane kubijyanye no guhuza flange hamwe nibikoresho byingutu.
Kubikorwa byohereza hanze, ibyemezo byibikoresho, inyandiko zivura ubushyuhe na raporo yumutungo wa mashini akenshi ni itegeko.
Dushyigikiye ibyangombwa byose birimo impamyabumenyi yikizamini hamwe na raporo yo kugenzura ibicuruzwa byinshi.
Muburyo bufatika, ntabwo aribisanzwe - intego yihuta.
Ubu ni ubwoko bwa sitidiyo yatoranijwe kuri sisitemu itwara hydrocarbone, hejuru - ubushyuhe bwamazi hamwe nuburemere buremereye bwinganda.
Niyo mpamvu ikomeje gukoreshwa cyane mu gutunganya inganda, inganda zitunganya imiti, imirimo yo gusana ibikorwa n’imishinga minini -.
Ingano isanzwe iboneka
| Diameter | Urwego | Uburebure busanzwe (mm) | Uburebure busanzwe (santimetero) | Guhuza ibinyomoro |
|---|---|---|---|---|
| M12 / 1/2" | UNC / Ibipimo | 50, 75, 100, 120 | 2", 3", 4", 5" | A194 2H |
| M16 / 5/8" | UNC / Ibipimo | 80, 100, 120, 150 | 3", 4", 5", 6" | A194 2H |
| M20 / 3/4" | UNC / Ibipimo | 100, 120, 150, 180 | 4", 5", 6", 7" | A194 2H |

| M30 / 1-1/4" | UNC / Ibipimo | 150, 180, 200, 250 | 6", 7", 8", 10" | A194 2H |
Ntiwibagirwe Imbuto
Ikintu kimwe duhora twibutsa abaguzi b'imishinga hamwe nitsinda ryo kubungabunga: sitidiyo ya B7 yizewe gusa nkibinyomoro byahujwe nayo.
Kuri ASTM A193 Icyiciro cya B7, ibyingenzi bihuye niASTM A194 Icyiciro cya 2H umutobe uremereye.
Ibice byombi byateguwe kugirango bikorere hamwe murwego rwo hejuru - flange flange hamwe nibikoresho byiteranijwe.
Gukoresha urwego rwo hasi - urwego rusanzwe rushobora kuganisha kumutwe mbere yuko sitidiyo igera kubushobozi bwayo bwateganijwe, bishobora guhinduka ibyago bikomeye mugihe cyo kwishyiriraho cyangwa kugerageza.
Kugira ngo twirinde ikintu icyo ari cyo cyose kidahuye kurubuga, mubisanzwe dutanga sitidiyo na 2H nimbuto zuzuye zuzuye, cyane cyane kubungabunga no guhagarika imishinga ya EPC.
Ibi bifasha amatsinda yo gutanga amasoko kugabanya amakosa yo kwishyiriraho no kubika umwanya wingenzi mugihe cyo gusana byihutirwa.
Kuki Kugura Ibikoresho bya Dongchao?
Turi uruganda rukora mu buryo butaziguye rufite icyicaro i Handan, ntabwo ari sosiyete y'ubucuruzi.
Ibyo bivuze ko buri cyegeranyo kiva kumurongo wumusaruro hamwe no kugenzura ubuziranenge buhamye, ibihe byihuta byo kuyobora hamwe nubufasha bwa tekinike busobanutse.
Kuberako twumva ko guhagarika uruganda, gutunganya peteroli no gusana ibikorwa remezo byihutirwa akenshi bikora kurwanya gahunda ihamye, tubika ububiko busanzwe bwa ASTM A193 B7 ingano yo kohereza vuba.
Buri cyiciro cy'umusaruro gitangwa hamwe naIcyemezo cyo gupima urusyo (MTC)kubushyuhe bwuzuye - umubare ukurikirana, bityo itsinda ryanyu ryiza nubugenzuzi rishobora kugenzura inkomoko yibintu wizeye.
Niba urimo kwitegura gusimbuza flange itaha, kubungabunga ibimera cyangwa umushinga wo kwiyubaka, ohereza gusa ingano nubunini bukenewe.
Turashobora gukata kuburebure, gutanga ubuso busabwa kurangiza no gutunganya ibyoherejwe byihuse ukurikije umushinga wawe.
Ibirangantego: astm a193 urwego b7 umukara wuzuye urudodo rwububiko, Ubushinwa astm a193 urwego b7 umukara wuzuye urudodo rwimyenda ikora, abatanga isoko
