Iipayipi zentsimbi ezingenamthungo ze-EN10210: Isikhokelo esiBanzi sokuThenga uBunjineli boLwakhiwo. Xa kufunwa iindawo ezingenanto ezakhiweyo zokwakha, iibhulorho, okanye ubunjineli boomatshini,Umgangatho we-EN10210Kubalulekile kakhulu kwiiprojekthi ezininzi zaseYurophu nezamazwe ngamazwe. Ukuqonda imiba ecacileyo yale nkcazo kubalulekile kubaphathi bokuthenga kunye neenjineli ukuze baphephe ixesha lokungasebenzi elibizayo, iingxabano zomgangatho, kunye nokulibaziseka kweprojekthi. Esi sikhokelo sigubungela yonke into ekufuneka uyazi malunga nemibhobho yentsimbi engenamthungo ye-EN10210, ukusuka kulwakhiwo lweekhemikhali ukuya kwiimeko zokuhanjiswa kunye neenkqubo zokuhlola.
1. Yintoni i-EN10210? (Iziseko)
I-EN10210-1 kunye ne-EN10210-2 zichaza iimeko zobuchwephesha zokuhanjiswa kwezixhobo ezingenanto ezigqityiweyo ezishushu ezenziwe ngeentsimbi ezingezizo ezomileyo nezicoliweyo. Ngokungafaniyo ne-EN10219 (ezenziwe ngokubandayo), i-EN10210 igubungela iimveliso ezigqityiweyo ezishushu. Inkqubo yokugqiba ngobushushu (ukulungisa okanye ukulungisa ukuqengqeleka) ikhulula uxinzelelo lwangaphakathi, ngaloo ndlela iphucula ukudityaniswa kunye nokuqinisekisa iipropati ezifanayo zoomatshini kububanzi bodonga.
2. IiBanga zeNsimbi eziPhambili phantsi koMgangatho we-EN10210
Ukukhetha uhlobo lwentsimbi olufanelekileyo linyathelo lokuqala lokufumana imveliso ephumelelayo. Lo mgangatho ugubungela amanqanaba aliqela, ahlulwe ngokwamandla okuvelisa kunye nokuqina kwempembelelo:
S235JRH: Intsimbi yesakhiwo esisisiseko, efanelekileyo kumaqondo obushushu angqongileyo.
S275J0H / S275J2H: Amandla aphezulu, asetyenziswa kakhulu kulwakhiwo ngokubanzi.
S355J0H/ S355J2H / S355K2H: Amanqanaba asetyenziswa kakhulu kwizakhiwo ezithwala imithwalo enzima.
E275 / E355 (Iingqolowa ezicolekileyo): Inika ukusebenza okuphezulu kakhulu kubushushu obuphantsi.
Icebiso Elibalulekileyo Lokuthenga: Soloko uqinisekisa ubushushu bovavanyo lokuchaphazela. U-"J0" ubonisa u-0°C, u-"J2" ubonisa u--20°C, kwaye u-"K2" ubonisa u--20°C kodwa ngokufunxwa kwamandla aphezulu (40J vs. 27J). Kwiiprojekthi ezikuMntla Yurophu okanye kwiindawo ezinemozulu ebandayo, ukusetyenziswa kwe-S355J2H okanye i-S355K2H kuyimfuneko.
3. Ukunyamezela kunye nobukhulu (Iinkcukacha ekufuneka ziqwalaselwe)
Ukunyamezelana kobukhulu obuphantsi komgangatho we-EN 10210 kungqongqo kunezo ziphantsi kwemigangatho ye-ASTM. Xa ubeka iodolo, nceda uqaphele:
Ukunyamezelana kweDayamitha yangaphandle (OD): Ngokwesiqhelo yi-±1% kwiimveliso ezigqityiweyo zishushu, kodwa soloko uqinisekisa itheyibhile ethile esemgangathweni.
Ukunyamezela Ubukhulu Bodonga: Ngokungafaniyo neetyhubhu ezenziwe ngokubanda, iityhubhu ezigqityiweyo zishushu azinawo unyamezelo olubi; oku kufuneka kubalwe kwiinkcukacha zobunjineli.
Ukunyamezela Ubunzima (Ubunzima): Qinisekisa ukuba umthengisi uqinisekisa ukuphambuka phakathi kobunzima obuqikelelwayo nobokwenyani (ngesiqhelo ngaphakathi kwe-±6%).
Icebiso lomthengi: Ukuba ufuna "ukunyamezelana okuhle" kubukhulu bodonga ukuqinisekisa umda wokhuseleko ngexesha lovavanyo lwe-hydrostatic olunoxinzelelo oluphezulu, nceda ucacise oku ngokucacileyo.
4. Imeko yokuhanjiswa kunye nonyango lobushushu
U-"H" kuluhlu (umz., S355J2H) ubonisa unyango lobushushu. Ngokwesiqhelo, oku kuthetha:
Ukuqengqeleka okuqhelekileyo (N)
Ukwakheka okuqhelekileyo (N)
Olu nyango lobushushu luphucula isakhiwo sengqolowa. Cela rhoqo iSatifikethi soVavanyo lweMill (MTC)—Uhlobo 3.1 okanye 3.2 ngokwe-EN 10204—ukuqinisekisa ukuba ubushushu obuqhelekileyo kunye nexesha lokubamba ziyahlangabezana neemfuno.
5. Uluhlu lokuHlola ukuThenga: Amanqaku ama-5 aPhambili Ngaphambi kokuSayina uMyalelo wokuThenga.
A. Umgangatho womphezulu kunye neziphene zangaphakathi
I-EN10210 iyalela ukuba umphezulu mawungabi nazimfanta, imijikelo, kunye nobukhulu. Nangona kunjalo, iziphene ezincinci zomphezulu ziyavunyelwa ukuba zihlala ngaphakathi kokunyamezelana okungalunganga.
Ingcebiso:Thetha "ngomda wokwaliwa" kwiziphene zomphezulu kwisivumelwano sakho. Qinisekisa ukuba kufuneka uhlolwe ngokubonakalayo nge-100% kunye ne-NDT (Uvavanyo Olungonakalisiyo) kwizicelo ezibalulekileyo.
B. Ukwakhiwa kweeKhemikhali kunye ne-CEV (Ixabiso elilinganayo leKhabhoni)
Kwizicelo ezisebenzisa kakhulu ukuwelda, iCarbon Equivalent Value (CEV) ibaluleke ngakumbi kunomxholo wekhabhoni kuphela.
I-EN10210 ithintela i-CEV ukuqinisekisa ukudityaniswa kakuhle. Kwiigreyidi ze-S355, i-CEV ihlala ikwi-≤ 0.45.
Isenzo:Cela umthengisi ukuba anike idatha yohlalutyo lwe-ladle, kungekhona nje amaxabiso ekujoliswe kuwo.
C. Uvavanyo lweMishini
Qinisekisa ukuba ezi mvavanyo zilandelayo zibandakanyiwe kwinkqubo yemveliso:
Uvavanyo lokuThamba (Ukunika amandla, i-UTS, uLongation %)
Uvavanyo lweMpembelelo (iCharpy V-notch kumaqondo obushushu athile)
Uvavanyo lokuGqiba (ukujonga ukuguguleka)
Uvavanyo lwe-Hydrostatic (ukuba luyimfuneko kwizicelo zoxinzelelo, nangona i-EN10210 isisiseko solwakhiwo, qinisekisa oku ngokwahlukileyo).
D. Ukugqiba Ukugqiba kunye noKhuseleko
Iziphelo Ezijijekileyo: Ukuze udibanise, cela iziphelo ze-bevel zesitayile se-API (30° +/- 5°) ezinomhlaba we-1.6mm.
Ii-End Caps: Soloko ucela ii-end caps zeplastiki ukukhusela imisonto kunye ne-bore kumswakama ngexesha lokuthutha elwandle.
E. Ukulandeleka
Yonke ipayipi mayiphawulwe ngokucacileyo ngelogo yomenzi, umgangatho oqhelekileyo (EN10210), inqanaba, ubungakanani, kunye nenombolo yobushushu.
Umthetho obalulekileyo: Yala nayiphi na into apho uphawu lwepeyinti-stencil lungafundekiyo; le yimpawu ebomvu yokulawula umgangatho ophantsi.
6. Iingxaki Eziqhelekileyo Kwi-EN10210 Sourcing
Ukudibanisa i-EN10210 ne-EN10219: Azitshintshi. I-EN10219 (eyenziwe ngokubandayo) inamandla aphezulu okuvelisa ngenxa yokusebenza ngokubandayo kodwa i-ductility ephantsi kunye noxinzelelo oluphezulu olushiyekileyo.
Ukungawuthatheli ngqalelo uMphumo Wokugqibezela Okushushu: Ixabiso le-EN10210 lidla ngokuba phezulu nge-8-15% kunelenziwe ngokubanda. Musa ukuyekelela ukuba uyilo lwakho lufuna ukunciphisa uxinzelelo emva kokuwelda.
Ukulibala malunga nokunyamezela ubude: I-EN10210 inikezela ngeendidi ezintathu zobude. Cacisa "Ubude obuchanekileyo" ukuba awudingi ukunciphisa iindleko zokuchitha imali.
7. Isaziso seNdalo kunye nokuThotyelwa kweMithetho
Njengoko kuhlaziyiwe kutshanje, qinisekisa ukuba umthengisi wakho uyayithobela imimiselo ye-REACH kunye ne-RoHS ukuba uthumela kwi-EU. Kwakhona, qinisekisa ukuba inkqubo yokwenza isinyithi ilandela imigangatho yeeNjongo zoPhuhliso oluZinzileyo (SDG)—oku kuba yimfuneko kwiithenda zikarhulumente zeziseko zophuhliso.
ukunamathela kwiindlela zokunyamezela ezichazwe kwiTheyibhile 3 ye-EN10210-2.
