Iipleyiti zentsimbi ezishushu eziqengqelekayo zaseYurophu: Iindlela zokukhetha izinto kunye nezicelo kwiiprojekthi zeziseko zophuhliso zehlabathi

Njengoko utyalo-mali lweziseko zophuhliso lwehlabathi luqhubeka lukhawuleza,Amaphepha esinyithi ashushu ajikeleziweyo aseYurophu asemgangathweni(umgangatho we-EN) ube yinxalenye ebalulekileyo kwiprojekthi zokwakha, amandla, ezothutho kunye nobunjineli obunzima kwihlabathi liphela. Ngemigangatho yokusebenza ebonakalayo, umgangatho wayo uyaqhubeka nokulawulwa ngokuthe chu nangokuhambelana namazwe ngamazwe, iphepha lesinyithi eligoqekileyo elishushu le-EN libe lukhetho oludumileyo kwiiprojekthi zasekuhlaleni eYurophu kunye nokuthunyelwa kwamanye amazwe kwihlabathi liphela.

Iipleyiti zentsimbi ezikwisakhiwo ziseyintsika yemarike

Phantsi kwe-EN 10025,iipleyiti zesinyithi ezishushu ezisongiweyozibangela isabelo esikhulu semfuno yemarike.

Uthotho lwe-S235, S275, kunye ne-S355zihlala zingamabakala achazwe rhoqo, ngalinye likhonza iimfuno ezahlukeneyo zesakhiwo:

Ipleyiti yentsimbi eshushu egoqwe yi-S235JR/J0/J2, enamandla amancinci okuvelisa angama-235 MPa, isetyenziswa kakhulu kwizakhiwo zentsimbi ngokubanzi, kwiibhari zokwakha, kwiikholamu, nakwiisiseko zoomatshini. Ukudityaniswa kwayo okugqwesileyo kunye nokusebenza kakuhle kweendleko kwenza ukuba ithelekiswe ne-ASTM A36, ngakumbi kwiiprojekthi zorhwebo kunye nezoshishino ezilula.

Ipleyiti yentsimbi ye-S275JR/J0/J2Inika amandla aphezulu ngelixa igcina ukusebenza kakuhle kokucubungula. Isetyenziswa rhoqo kwiibhulorho, oomatshini bobunjineli, kunye nezinto ezinomthwalo ophakathi.

Ipleyiti yentsimbi yekhabhoni ye-S355JR/J0/J2/K2, ethathwa kakhulu njengomgangatho ophambili wokuthumela ngaphandle, inika amandla amancinci okuvelisa angama-355 MPa kunye nokuqina okuphezulu. Olu mgangatho lusetyenziswa kakhulu kwizakhiwo zentsimbi enzima, ubunjineli beebhulorho, amaqonga aselunxwemeni, kunye neenqaba zamandla omoya, kwaye idla ngokuchazwa njengendlela eyahlukileyo endaweni ye-ASTM A572 Grade 50 okanye i-ASTM A992.

Iqela leNsimbi yasebukhosiniIingcali ziphawula ukuba iipleyiti zentsimbi ze-S355 ziyathandwa ngakumbi njengoko oorhulumente kunye nabaphuhlisi bezama ukuphucula ubunzima besakhiwo ngaphandle kokubeka emngciphekweni imida yokhuseleko.

Imfuno Ekhulayo Yokwenza Nokunyathela Iipleyiti Zentsimbi

Ngaphaya kwezicelo zesakhiwo,iipleyiti zentsimbi ezigoqiweyo ezishushuyokwenza nokunyathela phantsiEN 10111ziyanda ngamandla, ingakumbi kwicandelo leemoto kunye nelezinto ezilula.

Amabanga afana nalaDD11, DD12, DD13kunyeDD14zenzelwe umgangatho ophezulu womphezulu kunye nokusebenza okuphezulu kokwenza ubanda. Ezi zinto zisetyenziswa kakhulu kwiindawo zesakhiwo seemoto, kwiindawo ezixineneyo, nakwiindawo ezidityanisiweyo zentsimbi ekhaphukhaphu apho ukwakheka okuhlala kuhleli kubalulekile.

Intsimbi yeHSLA ixhasa uyilo olukhaphukhaphu nolunamandla aphezulu

Utshintsho oluya kubunjineli obukhaphukhaphu kunye nokusebenza kakuhle komthwalo kubangele imfuno yamandla aphezuluiipleyiti zentsimbi ezine-low-alloy (HSLA)phantsiEN 10149.

Amabanga aqukaI-S355MC, i-S420MCkunyeI-S460MCzibonelela ngolungelelwano oluqinileyo phakathi kwamandla aphezulu okuvelisa kunye nokudityaniswa. Ezi zinto zisetyenziswa ngakumbi koomatshini bokwakha, itshasi yelori, ii-crane booms, kunye nezixhobo zokuphakamisa, apho ukunciphisa ubunzima kuthetha ngokuthe ngqo ekusebenzeni okuphuculweyo kunye nokusebenza kakuhle kwepetroli.

Iipleyiti zentsimbi yesitya soxinzelelo zihlala zibalulekile kwiiprojekthi zamandla

Kwizicelo zamandla kunye nobushushu, iipleyiti zentsimbi zesitya soxinzelelo se-EN 10028 ziyaqhubeka nokuba yinto efunekayo.

P265GHkwayeP355GHzenzelwe ukusebenza kakuhle koomatshini phantsi kobushushu obuphezulu kunye noxinzelelo lwangaphakathi.

Izicelo eziqhelekileyo ziqukaiibhoyila, izitya zoxinzelelo, izixhobo zokutshintshiselana ubushushu, kunye nezixhobo ze-petrochemical.

Ngenxa yotyalo-mali oluqhubekayo ekuvelisweni kwamandla kunye nokulungiswa kwemizi-mveliso, imfuno yala manqanaba isaqhubeka izinzile kulo lonke elaseYurophu, eMbindi Mpuma, nakuMzantsi-mpuma Asia.

I-Weathering Steel Ifumana Ingqwalasela Kulwakhiwo Oluzinzileyo

Izinto eziqwalaselwe ngokuzinzileyo nazo ziphinda zibumbe ukhetho lwezinto eziphathekayo.Iipleyiti zentsimbi ezigubungele phantsi I-EN 10025-5, njengeS355JOWkwayeS355J2W,zichazwa ngakumbi kwiiprojekthi ezichatshazelwe ziimeko zomoya.

Ukumelana kwazo nokugqwala kwendalo kunciphisa isidingo sokugquma nokugcinwa rhoqo, nto leyo eyenza ukuba zibe zilungele iibhulorho, izakhiwo zentsimbi zangaphandle, iifaçade zokwakha, kunye nobunjineli bomhlaba. Abayili bayazixabisa nepatina yazo eyahlukileyo yomphezulu, ehambelana nobuhle bezakhiwo zanamhlanje.

Ngenxa yokuhlaziywa kweziseko zophuhliso zehlabathi, uphuhliso lwamandla avuselelekayo kunye nokuphuculwa kwezakhiwo zothutho oluqhubekayo, imfuno enamandla yepleyiti yesinyithi eshushu ejikeleziweyo esemgangathweni yaseYurophu iya kulindeleka kwimarike yamazwe ngamazwe. Amanqanaba ahlukeneyo, iipropati zoomatshini ezihambelanayo, kunye nezinye iinkqubo zokulinganisa zehlabathi, ezifana ne-ASTM, zenze ukuba ipleyiti yesinyithi ye-EN ibe lukhetho lwezinto eziyimfuneko kwizicelo zobunjineli kwimida.

Ukukhetha izinto eziphathekayo akusekho nje into yokuqwalasela ubuchwepheshe, kodwa sisigqibo esicwangcisiweyo njengoko abanini beeprojekthi begxila ngakumbi ekusebenzeni, ixesha elide, kunye neendleko zobomi.
