Kana tembiricha yekushanda yekabhoni simbi isingasviki -2 ℃, uye kana tembiricha yekabhoni simbi isingasviki 0 ℃, haina kukodzera kushandisa michina yekubaya nekuveura. Makobvu esimbi mahwendefa anokonzera makatsemuka mushure mekucheka kwewaya anofanirwa kurapwa kupisa nekukurumidza mushure mekunama, kana zvikasadaro post kupisa kurapwa kunofanira kuitwa. Iyo post weld kupisa kurapwa kweflanged rabha yekuwedzera yejoint ichaitwa zvinoenderana nezvinodiwa zveDL/T752, asi kune yakakura post weld kupisa kurapwa, tembiricha yekudzora tembiricha ichave 2 ℃ ~ 3 ℃ yakaderera pane yepakati uye yakaderera. tembiricha yezvinhu zvepakutanga mativi ese uye welding deposition.
Flange mhando yerubha yekuwedzera yejoini ichaiswa zvinoenderana nematanho anotevera:
1. Gadziriro: Chenesa furanji uye nzvimbo yekuvharisa pamativi ese epombi, uye tarisa kana maflange, mabhaudhi, uye gaskets zviri izvo uye hazvina kukuvara.
2. Kuiswa kweFlange: gadzirisa iyo flange yejojo yekuwedzera rabha neflange pamativi ese epombi, pfuudza bhaudhi nepakati.flangegomba, uye shandisa lubricant yakakodzera pane flange nut.
3. Gadzirisa chikwata chekuwedzera: mushure mekugadzirisa flange, gadzirisa hutungamiri uye nzvimbo yejojo yekuwedzera kwerabha kuti uichengetedze mumamiriro echisikigo uye udzivise kudzvinyirira kwakanyanya kana kudzvinyirira.
4. Fixed anchor rod: Kana anchor flange ichidiwa, tsvimbo yeanchor inoda kubatanidzwa kune flange uye yakasungirirwa pasi kana bhakiti kuburikidza nemichina yakagadziriswa yakadai semahwendefa eanchor.
5. Tight bolts: simbisa mabhoti alternately kubva kumativi ose kusvikira mabhoti ose asimbiswa zvakafanana uye zvine mwero kuti ave nechokwadi chekuvhara uye kushanda kwekubatanidza pakati peflange nejojo yekuwedzera kwerabha.
6. Kuongorora: pakupedzisira, tarisa kana iyo yese yekuisa maitiro inosangana nezvinodiwa, uye simbisa kana iyokuwedzera kubatanayakaiswa zvakanaka
Izvo zvinhu uye kuiswa kweiyo flanged rabha yekuwedzera yejoinhi inoratidza kumwe kutsauka, saka inogona kugadziridzwa zvinoenderana neiyo chaiyo yekumisikidza yakatarwa panguva yekuisa uye kugadzirisa, uye iyo radial yekutyaira simba inogona kuendeswa kune ese pipeline system software panguva yekushanda. Izvi hazvisi kungovandudza kushanda kwekushanda, asiwo kune imwe yekudzivirira pamichina yepombi semapombi nemavharuvhu.
Kuisa mirayiridzo yeflange rubber yekuwedzera joint. Kana tembiricha ichichinja, pombi inogona kuwedzera zvakasununguka uye chibvumirano pakati peiyo interface. Kana hwaro hwanyura, pombi inogona kurereka uye kuona kuti hapana kuvuza mukusunga, uyezve iine chinangwa chekuripira otomatiki.
Single flange muganho rabha yekuwedzera joint inokodzera kubatanidza neflange uye welding nepombi. Panguva yekuisa, gadzirisa urefu hwegungano pakati pemativi maviri echigadzirwa uye pombi kana flange, simbisa mabhaudhi anchor evhavhavhavha yevhavha symmetrically pakona yepamusoro, uye wozogadzirisa nzungu kuitira kuti pombi iwedzere uye kubvumirana zvakasununguka mukati meiyo. huwandu hwekudzosa uye kudzoreredza, kukiya kuwedzera uye kukanda huwandu, uye pombi inogona kushanda zvakavimbika. Flange inodzikamisa rubber yekuwedzera joint inokodzera kubatanidza mativi ese eflange. Panguva yekuisa, gadzirisa kureba kwekubatanidza kwemativi ese ezvigadzirwa, simbisa mabhoti ebhoneti zvakaenzana pamakona epamusoro, wobva wagadzirisa nati yekumisikidza, kuitira kuti pombi iwedzere uye kuwedzerwa pakuda, uye kureba kwemativi ese ari maviri. mudziyo wekuwedzera unogona kugadziriswa. Iyo rabha yekuwedzera yejoint inokodzera kubatanidza mativi ese nepombi isina magetsi welding, ine inonzwisisika chimiro, yakanaka yekuisa chisimbiso, uye nekukurumidza uye nyore kuisirwa.
Iyo imwe chete flange muganho werabha yekuwedzera yejoinhi ine imwe yakawanda-directional offset mhedzisiro mukushanda kwepombi, uye inoita basa rakakosha mukuwedzera kuripwa kwekuora mwoyo kwepasi uye nguva yekukotama nekuda kwekuwedzera kwekupisa mukushanda kwepombi. Naizvozvo, iyo rabha yekuwedzera yejoinhi inogona kuderedza kusunda simba rebofu ndiromukushanda kwepombi, uye ine kumwe kugadzirisa kwepombi, kunyanya kuisirwa nekugadzirisa pombi. Iyo imwe chete flange inodzikamisa rubber yekuwedzera yejoin ichave yakashongedzerwa nemichina yekumisikidza pahwaro hwekutanga maitiro ejoini yekuwedzera rabha, uye ichavharwa nenzungu panzvimbo ine huwandu hukuru hwekuwedzera. Iyo pombi inogona kukwidziridzwa zvisina tsarukano mukati meiyo inotenderwa yekuwedzera siyana, uye kana yangopfuura yakakura kuwedzera kwayo, inogona kuve nechokwadi chekushanda kwakavimbika kwepombi, kunyanya pamapaipi ane vibrate kana kumwe kurerekera uye kutenderedza makona.
