1.The welding tsvimbo ichachengetwa yakaoma panguva yekushandiswa. Iyo calcium titanate type ichaomeswa pa150'C kweawa imwe, uye iyo yakaderera-a hydrogen mhando ichaomeswa pa200-250 ℃ kweawa 1 (kuomeswa hakuzodzokororwe kakawanda, kana zvisina kudaro ganda riri nyore crack and peel off) kudzivirira iyo welding tsvimbo ganda, mafuta anonamira uye imwe tsvina, kuitira kudzivirira kuwedzera kabhoni yemukati we weld uye kukanganisa kunaka kweiyo weldment.
2.During welding ofStainless simbi flangepombi fittings, carbides inonatswa nekudzokororwa kupisa, izvo zvinoderedza ngura uye mechanical properties.
3.Iyo yakaomeswa American mwero flange ye chrome Stainless simbi flange pombi fittings pashure welding yakakura uye nyore kutsemuka. Kana mhando imwe chete yechromium Stainless steel electrode (G202, G207) ichishandiswa kugadzira, preheating inopfuura 300 ℃ uye inononoka kutonhora kurapwa kutenderedza 700 ℃ mushure mekunama kunodiwa. Kana iyo weldment isingagone kuve pasi pe-post-weld kupisa kurapwa, simbi isina tsvina flange pombi electrode (A107, A207) ichasarudzwa.
4.Kune flange yesimbi isina tsvina, huwandu hwakakodzera hwezvinhu zvakagadzikana zvakadai seTi, Nb uye Mo zvinowedzerwa kuti zvivandudze kurwisana nekuora uye weldability. Iyo weldability iri nani pane iyo yechrome Stainless simbi flange. Kana iyo imwechete yemhando ye chrome Stainless simbi flange welding tsvimbo (G302, G307) inoshandiswa, preheating pamusoro pe200 ℃ uye kupisa kutenderedza 800 ℃ mushure mekunama kunozoitwa. Kana iyo weldment isingakwanise kupisa kupisa, simbi isina tsvina flange pombi electrode (A107, A207) ichasarudzwa.
5.Stainless simbi flange pombi fittings uye butt-welding flange welding rods ane yakanaka corrosion resistance uye chemical resistance, uye anoshandiswa zvakanyanya mumakemikari, fetiraiza, peturu nekugadzira michina.
6.Kuitira kudzivirira ziso-ku-ziso corrosion inokonzerwa nekupisa kwechifukidziro cheflange, ikozvino welding haifaniri kunge yakakura, inenge 20% pasi peiyo carbon steel electrode, iyo arc haifaniri kunge yakareba kwenguva refu, uye kutonhora kwemukati-kati hakufanirwe kunonoka, uye yakamanikana weld bead inofanira kusarudzwa.
Iyo kabhoni simbi flange inoshandiswa nenzira yakakosha, saka inoda yakatsetseka, yakatsiga, inomanikidza, torsional uye mamwe maitiro ezvigadzirwa. Inogona kushandiswa pasi pekumanikidzwa kwakanyanya pasina kukanganisa. Nekuti kabhoni simbi ine mashoma mabhura, simba rayo rekukwesha idiki zvakare, uye rinogona kushandiswa zvakanyanya mumidziyo.
Uye zvakare, kabhoni simbi flanges inofanirwa kugadzirwa ichinyatsoenderana neChina kana yakakodzera indasitiri zviyero. Usamboshandisa zvinhu zvisina kukodzera kuzvigadzira. Kunyanya iwe haugone kutema makona pahukuru, nzira idzi dzinogoneka dzinotungamira kune zvigadzirwa zvakaderera uye zvisina kukodzera, izvo zvinokonzeresa kukundikana kune iyo yose French system, kunyange kukonzera kurasikirwa kwehupfumi kwepfuma uye vakakuvara uye dzimwe tsaona dzakagadzikana.
Chero ani akambonzwa nezve carbon steel flange anoziva kuti kukanda kwayo zvinhu kwakaoma. Panyaya yezvinyorwa zvayo, carbon simbi yakasiyanawo nedzimwe simbi, uye kushanda kwayo kuri nani kudarika kwesimbi. Saka flange yakanaka inonyanya kugadzirwa nekabhoni simbi, ndiko kuti, iyo inonzi kabhoni simbi flange. Pamusoro pekabhoni, kabhoni simbi inowanzo ine diki silicon, manganese, sarufa, phosphorous uye zvimwe zvinhu, saka ine hunhu hwayo muzvinhu.
Iyo yekuyera nzira yekabhoni simbi flange uye basa rekugadzirira pamberi pekuyera ichaunzwa muchidimbu nemupepeti.
1.Panguva yekuyera, vanhu vatatu vanofanira kurongeka, vaviri vavo vari kuyera, mumwe ari kutarisa nekuzadza fomu. Kana pasina mamiriro ekushandisa ekunze caliper uye mutongi wesimbi, iyo caliper inogona kushandiswa seyeyero mudziyo. Measurement ibasa rine hunyanzvi uye chinodiwa pakuisa zvigadziriso. Chiyero nerekodhi zvichagadzirwa nemazvo, uye fomu richazadzwa nemazvo uye zvakajeka. Mubasa rekuyera chairo. Kuti tishandire pamwe chete, tinofanira kukwanisa kubatira pamwe uye kushandisa mukuwirirana nenheyo dzakarurama.
2. Zvichienderana nechinzvimbo cheflange yakakura isati yayera, dhayagiramu yekubatanidza uye nhamba yeflange yakakura yemidziyo inofanirwa kudhirowewa pakutanga, kuitira kuti chigadziriso chigone kuisirwa zvinoenderana nenzira dzinoenderana nemisimboti, uye yakajairika kushandiswa. inogona kutsunga.
3.Nekuda kwekuti iyo dhayamita yekunze yekabhoni simbi flange inogona kunge yakasiyana, gomba risiri iro (rakasiyana pakati) uye ukobvu hwegasket hwakasiyana, iyo yakagadziriswa inogadziriswa haifanirwe kuchinjika nedivi carbon steel flange, saka kuyera ukuru uye. huwandu hwechikamu chimwe nechimwe ndicho chinhu chikuru. Ixtere kugadzirisa uye kuisa.
Carbon steel flangesanoshandiswa zvakanyanya mumashandisirwo ezuva nezuva, uye kushandiswa hakusi kunonoka. Naizvozvo, kugara uchichengetedza kabhoni simbi flanges inoda kuve nemitemo inoenderana kuchengetedza kunaka kwekabhoni simbi flanges zvakanyanya sezvinobvira uye kuvandudza kumhanya kwekushanda. Pano tinogovana newe kushanda kwakagadzikana kwesimbi isina tsvina uye kabhoni simbi flanges uye chii chinoda kugadziriswa:
1.Kana carbon steel flange yakavharwa, kuchine imwe yepakati yakasara mumutumbi wevhavha, uye inotakurawo kudzvinyirirwa kunotsanangurwa. Usati wagadzirisa kabhoni simbi flange, vhara vharafu yekuvhara pamberi pekabhoni simbi flange, vhura kabhoni simbi flange kuti iwedzere, uye sunungura zvachose kumanikidza kwemukati kwemuviri wevharuvhu. Kana iri yemagetsi kabhoni simbi flange kana pneumatic bhora vharafu, simba uye mhepo inopa inofanira kubviswa pakutanga.
2.Kazhinji, iyo yakapfava yakavharidzirwa kabhoni simbi flange inoshandisa tetrafluoroethylene (PTFE) sechinhu chekuisa chisimbiso, uye nzvimbo yekuisa chisimbiso chevhavha yebhora yakaoma inogadzirwa nesimbi yakatarisana. Kana zvakakosha kuchenesa pombi bhora revhavha, kutarisirwa kunofanira kutorwa kudzivirira kubuda nekuda kwekukuvara kwechisimbiso chemhete panguva yekuparara.
3.Paunenge uchiparadzanisa carbon steel flange, mabhoti uye nuts paflange inofanira kugadziriswa kutanga, uye ipapo makungu ose anofanira kusimbiswa zvishoma uye zvakasimba zvakasimba. Kana nzungu dzega dzega dzakagadziriswa zvakanaka dzimwe nzungu dzisati dzagadziriswa, iyo gasket surface ichakuvadzwa kana kutsemuka nekuda kwekusaenzana kurodha pakati pezviso zveflange, zvichikonzera kubuda kwepakati kubva pavhavha flange butt joint.
4.Kana iyo valve yakacheneswa, iyo yakagadziriswa inoshandiswa haingapesani nezvikamu zvinofanira kucheneswa uye haifaniri kuparara. Kana iri kabhoni simbi flange yegasi, inogona kucheneswa nepeturu. Zvimwe zvikamu zvinogona kucheneswa nemvura yakadzorerwa. Panguva yekuchenesa, guruva rakasara, mafuta uye zvimwe zvakabatanidzwa zvichacheneswa zvachose. Kana vasingakwanisi kucheneswa nemvura yakachena, vanogona kucheneswa nedoro uye mamwe majekiseni ekuchenesa pasina kukuvadza muviri wevhavha uye zvikamu. Mushure mekuchenesa, mirira kuti mumiriri wekuchenesa aite simba risati rasangana.
5.Kana kudonha kudiki kunowanikwa pakurongedza panguva yekushandiswa, iyo valve tsvimbo nut inogona kuomeswa zvishoma kusvikira kudonha kwamira. Usaramba uchiomesa.
6.Isati yashandiswa, pombi uye chikamu chekufashukira chemuviri wevhavha chichacheneswa nemvura kudzivirira masimbi akasara uye mamwe maturu kuti asapinda mukati memukati wemuviri wevhavha.
Mukuwedzera, kana carbon steel flange yakaiswa kunze kwenguva yakareba, uye pasina matanho ekutya mvura, zvinotungamirira mukuora kwemamwe miviri yevhavha uye zvikamu. Nenzira iyi, zvinodikanwa kuedza kugadzikana kwekabhoni simbi flange panguva yekushandiswa.
