Amapuleti Ensimbi Ashisayo Agoqiwe AseYurophu: Izitayela Zokukhetha Izinto kanye Nezicelo Kumaphrojekthi Engqalasizinda Yomhlaba Wonke

Njengoba ukutshalwa kwezimali kwengqalasizinda yomhlaba wonke kuqhubeka nokusheshisa,Amashidi ensimbi ashisayo ajwayelekile aseYurophu(i-EN standard) ibilokhu iyingxenye ebalulekile kumaphrojekthi okwakha, amandla, ezokuthutha kanye nobunjiniyela obunzima emhlabeni jikelele. Njengoba inezinga lokusebenza elisobala, ikhwalithi yayo iyaqhubeka nokulawulwa njalo nangokuhambisana nomhlaba wonke, ishidi lensimbi eligoqiwe elishisayo le-EN seliye laba ukukhetha okuthandwayo kumaphrojekthi endawo eYurophu kanye nokuthunyelwa kwamanye amazwe emhlabeni jikelele.

Amapuleti Ensimbi Esakhiwe Ahlala Eyinsika Yemakethe

Ngaphansi kwe-EN 10025,amapuleti ensimbi ashisiwe akhiwe ngesakhiwobabangela isabelo esikhulu kunazo zonke sesidingo semakethe.

Uchungechunge lwe-S235, S275, kanye ne-S355ihlala iyimaki avame ukucaciswa, ngalinye likhonza izidingo zesakhiwo ezihlukile:

Ipuleti lensimbi eligoqiwe elishisayo le-S235JR/J0/J2, enamandla okukhiqiza okungenani angu-235 MPa, isetshenziswa kabanzi ezakhiweni zensimbi ezijwayelekile, imishayo yokwakha, amakholomu, kanye nezisekelo zemishini. Ukushibilika kwayo okuhle kakhulu kanye nokusebenza kahle kwezindleko kwenza ifane ne-ASTM A36, ikakhulukazi kumaphrojekthi ezimboni zezentengiselwano nezilula.

Ipuleti lensimbi le-S275JR/J0/J2inikeza amandla aphezulu ngenkathi igcina ukusebenza okuhle kokucubungula. Ivame ukusetshenziswa emabhulohweni, emishinini yobunjiniyela, kanye nasezingxenyeni ezithwala umthwalo ophakathi.

Ipuleti lensimbi yekhabhoni le-S355JR/J0/J2/K2, ebhekwa kabanzi njengebanga elihamba phambili lokuthumela ngaphandle, inikeza amandla okukhiqiza okungenani angu-355 MPa kanye nokuqina okuphezulu. Leli banga lisetshenziswa kakhulu ezakhiweni zensimbi esindayo, ubunjiniyela bamabhuloho, amapulatifomu asogwini, kanye nemibhoshongo yamandla omoya, futhi ivame ukucaciswa njengenye indlela esikhundleni se-ASTM A572 Grade 50 noma i-ASTM A992.

Iqembu Lensimbi Yasebukhosiniochwepheshe baphawula ukuthi amapuleti ensimbi e-S355 ayathandwa kakhulu njengoba ohulumeni nabathuthukisi befuna ukuthuthukisa isisindo sesakhiwo ngaphandle kokubeka engcupheni imingcele yokuphepha.

Isidingo Esikhulayo Sokwakha Nokunyathela Amapuleti Ensimbi

Ngaphandle kwezicelo zesakhiwo,amapuleti ensimbi ashisiwe ashisayoyokwenza nokunyathela ngaphansiI-EN 10111ziyanda, ikakhulukazi emikhakheni yezimoto kanye neyokukhiqiza izinto ezilula.

Amabanga afana nalawaDD11, DD12, DD13, futhiI-DD14zenzelwe ikhwalithi ephezulu kakhulu yendawo kanye nokusebenza kahle kakhulu kokwenza ubanda. Lezi zinto zisetshenziswa kabanzi ezingxenyeni zesakhiwo sezimoto, izingxenye ezigxiviziwe, kanye nezinsimbi ezilula lapho ukwakheka okuhambisanayo kubalulekile khona.

Insimbi ye-HSLA Isekela Umklamo Olula Nonamandla Aphezulu

Ukushintshela kubunjiniyela obulula kanye nokusebenza kahle komthwalo okuphezulu kuholele ekudingweni kwamandla aphezuluamapuleti ensimbi ane-alloy ephansi (HSLA)ngaphansiI-EN 10149.

Amabanga afaka phakathiI-S355MC, i-S420MC, futhiI-S460MCinikeza ibhalansi eqinile phakathi kwamandla aphezulu okukhiqiza kanye nokushibilika. Lezi zinto zisetshenziswa kakhulu emishinini yokwakha, i-chassis yamaloli, ama-crane boom, kanye nemishini yokuphakamisa, lapho ukunciphisa isisindo kuholela ngqo ekusebenzeni okuthuthukisiwe kanye nokusebenza kahle kukaphethiloli.

Amapuleti Ensimbi Yesitsha Esicindezelekile Ahlala Ebalulekile Kumaphrojekthi Amandla

Ngokusetshenziswa kwamandla nokushisa, amapuleti ensimbi emikhumbi yokucindezela ye-EN 10028 ayaqhubeka nokuba yinto ebaluleke kakhulu.

I-P265GHfuthiI-P355GHzenzelwe ukusebenza kahle kwemishini okuzinzile ngaphansi kwamazinga okushisa aphezulu kanye nengcindezi yangaphakathi.

Izinhlelo zokusebenza ezijwayelekile zifaka phakathiama-boiler, imikhumbi yokucindezela, ama-heat exchanger, kanye nemishini ye-petrochemical.

Njengoba kutshalwa imali okuqhubekayo ekukhiqizweni kukagesi nasekucutshungulweni kwezimboni, isidingo salezi zigaba sihlala sizinzile kulo lonke elaseYurophu, eMpumalanga Ephakathi, naseNingizimu-mpumalanga ye-Asia.

Insimbi Yokubheka Izulu Ithola Ukunakwa Ekwakhiweni Okusimeme

Izinto ezicatshangelwayo zokuzinza nazo zishintsha ukukhetha kwezinto ezibonakalayo.Amapuleti ensimbi agubhayo ngaphansi I-EN 10025-5, njengeS355JOWfuthiS355J2W,zichazwa kakhulu kumaphrojekthi abhekene nezimo zomkhathi.

Ukumelana kwazo ngokwemvelo nokugqwala kunciphisa isidingo sokumbozwa nokugcinwa njalo, okwenza zibe zilungele amabhuloho, izakhiwo zensimbi zangaphandle, ama-façade okwakha, kanye nobunjiniyela bezindawo. Abaklami bayawazisa futhi ama-patina abo ahlukile, ahambisana nobuhle bezakhiwo zesimanje.

Njengoba kuqhubeka ukulungiswa kwengqalasizinda yomhlaba wonke, ukuthuthukiswa kwamandla avuselelekayo kanye nokuthuthukiswa kwezikhungo zokuhamba, isidingo esinamandla sepuleti lensimbi eligoqiwe elijwayelekile laseYurophu sizolindeleka emakethe yamazwe ngamazwe. Amabanga ahlukile, izakhiwo zemishini ezihambisanayo, kanye nezinye izinhlelo zokulinganisa zomhlaba wonke, njenge-ASTM, kwenze ipuleti lensimbi le-EN laba inketho yezinto ezibonakalayo ezinhlelweni zobunjiniyela ngaphesheya kwemingcele.

Ukukhetha izinto ezibonakalayo akuseyona nje indaba yokucatshangelwa kobuchwepheshe, kodwa kuyisinqumo esihlakaniphile njengoba abanikazi bamaphrojekthi begxila kakhulu ekusebenzeni, isikhathi eside, kanye nezindleko zokuphila.
