Mapurati eSimbi Akaputirwa neMagariro eEuropean Standard Hot Rolled: Maitiro ekusarudza Zvinhu uye Mashandisirwo muMapurojekiti ePasirose eInfrastructure

Sezvo mari yekudyara muzvivakwa zvepasi rose iri kuramba ichikwira,Machira esimbi anopisa akaputirwa eEurope(EN standard) yave iri chikamu chakakosha mukuvaka, simba, kutakura uye mapurojekiti einjiniya akakura pasi rose. Nekuonekwa kwemaitiro ayo, hunhu hwayo hunoramba huchidzorwa zvishoma nezvishoma uye hunoenderana nepasi rose, jira resimbi rinopfurwa rinopisa reEN grade rave sarudzo yakakurumbira kumapurojekiti emuno muEurope pamwe nekutengesa kunze kwenyika pasi rese.

Mapurati eSimbi Ekuvaka Anoramba Ari Mutsigiro weMusika

Pasi peEN 10025,mapurati esimbi anopisa akamonerwa echimirondiyo inonyanya kudiwa pamusika.

S235, S275, uye S355 nhevedzanoinoramba iri mamakisi anowanzo tsanangurwa, imwe neimwe ichipa zvinodiwa zvakasiyana zvechimiro:

S235JR/J0/J2 ndiro yesimbi inopisa yakakungurutswa, ine simba rekugadzira re235 MPa, inoshandiswa zvakanyanya muzvivakwa zvesimbi, matanda ekuvaka, makoramu, uye mabhesi emakanika. Kugona kwayo kupinza simbi zvakanaka uye kushanda kwayo zvakanaka kunoita kuti ifanane neASTM A36, kunyanya mumapurojekiti ebhizinesi nemaindasitiri akareruka.

S275JR/J0/J2 ndiro yesimbiinopa simba rakawanda uku ichiramba ichishanda zvakanaka. Inowanzo shandiswa mumabhiriji, michina yeinjiniya, uye zvikamu zvinotakura mutoro wepakati.

S355JR/J0/J2/K2 ndiro yesimbi yekabhoni, inoonekwa zvakanyanya segiredhi rekutengesa kunze kwenyika, inopa simba rekukohwa risingasviki 355 MPa pamwe nekusimba kwakanyanya. Iri giredhi rinoshandiswa zvakanyanya muzvivakwa zvesimbi zvinorema, mainjiniya emabhiriji, mapuratifomu ekunze, uye mashongwe esimba remhepo, uye inowanzo tsanangurwa seimwe nzira yeASTM A572 Grade 50 kana ASTM A992.

Boka reSimbi reRoyalNyanzvi dzinoti mapurati esimbi eS355 ari kufarirwa zvakanyanya sezvo hurumende nevagadziri vemapurani vachitsvaga kuwedzera huremu hwechivakwa pasina kukanganisa miganhu yekuchengetedza.

Kudiwa Kunowedzera Kwekugadzira Nekutsikisa Mapureti Esimbi

Kunze kwekushandiswa kwechimiro,maplate esimbi anopisa akamonerwayekuumba nekutsikirira pasiEN 10111zviri kuwedzera simba, kunyanya muzvikamu zvemotokari nekugadzira zvinhu zvidiki.

Magiredhi akadai seDD11, DD12, DD13uyeDD14Zvakagadzirirwa kunaka kwepamusoro uye kushanda zvakanaka kwekugadzira zvinhu zvinotonhora. Zvinhu izvi zvinoshandiswa zvakanyanya muzvikamu zvemagadzirirwo emotokari, zvikamu zvakadhindwa, uye simbi dzakareruka uko kuumbwa kwakafanana kwakakosha.

Simbi yeHSLA Inotsigira Dhizaini Yakareruka Uye Yakasimba

Kuchinja kweinjiniya yakareruka uye kushanda zvakanaka kwemutoro kwaita kuti pave nezvinodiwa zvemagetsi ane simba rakawanda.mapurati esimbi ane low-alloy (HSLA)pasiEN 10149.

Magiredhi anosanganisiraS355MC, S420MCuyeS460MCinopa chiyero chakasimba pakati pesimba guru rekugadzira uye kugona kuchinjika. Zvinhu izvi zviri kushandiswa zvakanyanya mumichina yekuvaka, chassis yemarori, crane booms, uye michina yekusimudza, uko kuderedza huremu kunoshandura zvakananga kushanda zvakanaka uye kushanda zvakanaka kwemafuta.

Mapurati esimbi emidziyo yepressure achiri kukosha zvikuru pamapurojekiti emagetsi

Pakushandiswa kwesimba nekupisa, maplate esimbi emidziyo inomanikidzwa yeEN 10028 anoramba achikosha.

P265GHuyeP355GHzvakagadzirwa kuti zvishande zvakanaka kana tembiricha yakakwira uye kumanikidzwa kwemukati.

Mashandisirwo akajairika anosanganisiramabhoyira, midziyo yekumanikidza, zvinochinja-chinja kupisa, uye michina yepetrochemical.

Nekudyara mari kuri kuramba kuchienderera mberi mukugadzira magetsi uye kugadzirisa maindasitiri, kudiwa kwemhando idzi kuchiri kuramba kwakasimba muEurope, Middle East, neSoutheast Asia.

Simbi yeWeathering Yawana Kutariswa Mukuvaka Kunogara Kwakagadzikana

Kufunga nezvekuchengetedza zvinhu zviri kuumbawo sarudzo yezvinhu.Mapureti esimbi anokwidibira pasi EN 10025-5, zvakaita seS355JOWuyeS355J2W,zvinotsanangurwa zvakanyanya kune mapurojekiti ari mumamiriro ekunze.

Kusagadzikana kwavo nengura kwechisikigo kunoderedza kudiwa kwekuputira nekugadzirisa nguva nenguva, zvichiita kuti zvive zvakanaka pamabhiriji, zvivakwa zvesimbi zvekunze, mafaçade ekuvaka, uye mainjiniya enzvimbo. Vagadziri vanokoshesawo jira ravo repamusoro rakasiyana, iro rinoenderana nerunako rwemazuva ano rwekuvaka.

Zvichienderana nekugadziriswa kwezvivakwa zvepasi rose, kuvandudzwa kwesimba rinogona kushandiswazve uye kuvandudzwa kwenzvimbo dzekufambisa kuri kuenderera mberi, kudiwa kwakasimba kweplate yesimbi inopfurwa yakajairwa yeEurope kuchatarisirwa mumusika wepasi rose. Magiredhi akasiyana, hunhu hwemakanika hwakafanana, uye mamwe masisitimu epasi rose ekuyera, akadai seASTM, zvakaita kuti plate yesimbi yeEN ive sarudzo yehunyanzvi mukushandiswa kweinjiniya kumiganhu.

Sarudzo dzezvinhu hazvichisiri nyaya yekufunga nezvehunyanzvi chete, asi sarudzo yehurongwa sezvo varidzi vemapurojekiti vachinyanya kutarisa mashandiro, hupenyu hurefu, uye mutengo wehupenyu.
