Amapayipi Ensimbi Angenamthungo e-EN10210: Umhlahlandlela Ophelele Wokuthengwa Kobunjiniyela Bezakhiwo. Lapho kutholakala izingxenye ezingenalutho zesakhiwo zokwakha, amabhuloho, noma ubunjiniyela bemishini,Izinga elijwayelekile le-EN10210Kubalulekile kakhulu kumaphrojekthi amaningi aseYurophu nakwamanye amazwe. Ukuqonda izici zalesi sigaba kubalulekile kubaphathi bezokuthengwa kwempahla kanye nonjiniyela ukuze bagweme isikhathi esibizayo sokungasebenzi, izingxabano zekhwalithi, kanye nokubambezeleka kwephrojekthi. Lo mhlahlandlela uhlanganisa konke okudingeka ukwazi mayelana namapayipi ensimbi angenamthungo e-EN10210, kusukela ekwakhiweni kwamakhemikhali kuya ezimweni zokulethwa kanye nezinqubo zokuhlola.
1. Kuyini i-EN10210? (Izisekelo)
I-EN10210-1 kanye ne-EN10210-2 zichaza izimo zokulethwa kobuchwepheshe zezingxenye zesakhiwo ezingenalutho eziqediwe ngokushisa ezenziwe ngezinsimbi ezingezona i-alloy kanye nezinhlayiya ezincane. Ngokungafani ne-EN10219 (ezakhiwe ngokubandayo), i-EN10210 ihlanganisa imikhiqizo eqediwe ngokushisa. Inqubo yokuqeda ngokushisa (ukulungisa noma ukulungisa ukugoqa) inciphisa ukucindezeleka kwangaphakathi, ngaleyo ndlela ithuthukise ukushibilika futhi iqinisekise izakhiwo ezifanayo zemishini kulo lonke ubukhulu bodonga.
2. Amamaki Ensimbi Eyinhloko ngaphansi kwe-EN10210 Standard
Ukukhetha izinga lensimbi elifanele kuyisinyathelo sokuqala sokuthola inzuzo. Indinganiso ihlanganisa amazinga amaningana, ahlukaniswe ngamandla okukhiqiza kanye nokuqina komthelela:
S235JRH: Insimbi eyisisekelo yokwakha, efanelekile emazingeni okushisa azungezile.
S275J0H / S275J2H: Amandla aphezulu, avame ukusetshenziswa ekwakheni okuvamile.
S355J0H/ S355J2H / S355K2H: Amabanga asetshenziswa kakhulu ezakhiweni ezithwala imithwalo esindayo.
E275 / E355 (Okusanhlamvu Okucolekile): Inikeza ukusebenza okuphezulu kakhulu ekushiseni okuphansi.
Icebiso Elibalulekile Lokuthenga: Njalo qinisekisa izinga lokushisa lokuhlola umthelela. I-"J0" ikhomba u-0°C, i-"J2" ikhomba u--20°C, kanye ne-"K2" ikhomba u--20°C kodwa ngokumuncwa kwamandla aphezulu (40J vs. 27J). Kumaphrojekthi aseNyakatho Yurophu noma ezindaweni ezinesimo sezulu esibandayo, ukusetshenziswa kwe-S355J2H noma i-S355K2H kuyimpoqo.
3. Ukubekezelelana kanye nobukhulu (Imininingwane okufanele uyihlole)
Ukubekezelelana kobukhulu ngaphansi kwendinganiso ye-EN 10210 kuqinile kunalezo ezingaphansi kwendinganiso ye-ASTM. Uma ubeka i-oda, sicela uqaphele:
Ukubekezelelana Kwangaphandle Kobubanzi (OD): Ngokuvamile ±1% yemikhiqizo eqediwe ngokushisa, kodwa qinisekisa njalo ithebula elithile elijwayelekile.
Ukubekezelela Ubukhulu Bodonga: Ngokungafani namapayipi akhiwe ngokubandayo, amapayipi aqediwe ngokushisa anokubekezelela okungekuhle; lokhu kumele kubalwe ezimisweni zobunjiniyela.
Ukubekezelela Isisindo (Isisindo): Qinisekisa ukuthi umhlinzeki uqinisekisa ukuphambuka phakathi kwesisindo esingokombono kanye nesisindo sangempela (ngokuvamile ngaphakathi kuka-±6%).
Icebiso Lomthengi: Uma udinga "ukubekezelelana okuhle" ekujikeni kodonga ukuqinisekisa ukuthi kukhona umkhawulo wokuphepha ngesikhathi sokuhlolwa kwe-hydrostatic okunomfutho ophezulu, sicela ucacise lokhu ngokucacile.
4. Isimo Sokulethwa Nokwelashwa Kokushisa
U-"H" esibonelweni sebanga (isb., S355J2H) ubonisa ukwelashwa kokushisa. Ngokuvamile, lokhu kusho ukuthi:
Ukugoqa okuvamile (N)
Ukwakheka okuvamile (N)
Lokhu kwelashwa kokushisa kucwengisisa isakhiwo sezinhlamvu. Cela njalo iSitifiketi Sokuhlolwa Komshini (i-MTC)—Uhlobo 3.1 noma 3.2 ngokwe-EN 10204—ukuqinisekisa ukuthi izinga lokushisa elijwayelekile kanye nesikhathi sokubamba ziyahlangabezana nezidingo.
5. Uhlu Lokuhlola Lokuthengwa Kwempahla: Amaphuzu Ayisihluthulelo Ama-5 Ngaphambi Kokusayina I-oda Lokuthenga.
A. Ikhwalithi Yomphezulu kanye Neziphambeko Zangaphakathi
I-EN10210 iyalela ukuthi indawo engaphezulu kumele ingabi nemifantu, imiphetho, kanye nobukhulu. Kodwa-ke, amaphutha amancane ebusweni ayavunyelwa uma ehlala ngaphakathi kokubekezelelana okungekuhle.
Isincomo:Xoxani "ngomkhawulo wokwenqatshwa" weziphambeko zobuso enkontilekeni yakho. Phikelela ekuhlolweni okubonakalayo okungu-100% kanye ne-NDT (Ukuhlolwa Okungabhubhisi) kwezicelo ezibalulekile.
B. Ukwakheka Kwamakhemikhali kanye ne-CEV (Inani Elilinganayo Nekhabhoni)
Ngezicelo ezisebenzisa kakhulu ukushisela, i-Carbon Equivalent Value (CEV) ibaluleke kakhulu kunokuqukethwe kwekhabhoni kuphela.
I-EN10210 ikhawulela i-CEV ukuqinisekisa ukushibilika okuhle. Kumagreyidi e-S355, i-CEV ivame ukuhlala ku-≤ 0.45.
Isenzo:Cela umhlinzeki ukuthi anikeze idatha yokuhlaziya i-ladle yangempela, hhayi nje amanani aqondiwe.
C. Ukuhlolwa Kwemishini
Qinisekisa ukuthi izivivinyo ezilandelayo zifakiwe ekukhiqizweni:
Ukuhlolwa Kokunwebeka (Amandla Okukhiqiza, i-UTS, Ukwandiswa %)
Ukuhlolwa Komthelela (i-Charpy V-notch emazingeni okushisa acacisiwe)
Ukuhlolwa Kokuthamba (ukuhlola ukuqina)
Ukuhlolwa kwe-Hydrostatic (uma kudingeka ekusetshenzisweni kwengcindezi, yize i-EN10210 ngokuyinhloko iwukwakheka, qinisekisa lokhu ngokwehlukile).
D. Ukuqeda Nokuvikela Ukuqeda
Iziphetho Ezigobile: Ukuze ushisele, cela iziphetho ze-bevel zesitayela se-API (30° +/- 5°) ezinezwe elingu-1.6mm.
Ama-End Caps: Cela njalo ama-end caps epulasitiki ukuze avikele imicu kanye nembobo emswakama ngesikhathi sokuthutha olwandle.
E. Ukulandelela
Ipayipi ngalinye kumele liphawulwe ngokucacile ngelogo yomenzi, okujwayelekile (EN10210), ibanga, usayizi, kanye nenombolo yokushisa.
Umthetho obalulekile: Yenqaba noma yikuphi ukwaziswa lapho uphawu lwepensele nopende lungafundeki khona; lokhu kuyisibonakaliso esibomvu sokulawulwa kwekhwalithi embi.
6. Izingibe Ezivamile Ekutholakaleni Kwe-EN10210
Ukudideka i-EN10210 ne-EN10219: Azikwazi ukushintshaniswa. I-EN10219 (eyakhiwe ngokubandayo) inamandla aphezulu okukhiqiza ngenxa yokusebenza okubandayo kodwa i-ductility ephansi kanye nokucindezeleka okuphezulu okusele.
Ukungawunaki Umthelela Wokuqedwa Okushisayo: Izindleko ze-EN10210 ngokuvamile ziphakeme ngo-8-15% kunezo ezibandayo. Ungayeki uma umklamo wakho udinga ukunciphisa ukucindezeleka ngemva kokushisela.
Ukukhohlwa Ngokubekezelela Ubude: I-EN10210 inikeza izigaba ezintathu zobude. Cacisa "Ubude Obuqondile" uma udinga ukunciphisa okungu-zero ukuze wonge izindleko zokuchitha.
7. Inothi Lezemvelo Nokuthobela Imithetho
Njengoba kusanda kubuyekezwa, qiniseka ukuthi umhlinzeki wakho uhambisana nemithethonqubo ye-REACH kanye ne-RoHS uma ethunyelwa e-EU. Futhi, qinisekisa ukuthi inqubo yokwenza insimbi ilandela amazinga e-Sustainable Development Goals (SDG)—lokhu kuba yimfuneko yokunikezwa kwezinsizakalo zikahulumeni zengqalasizinda.
ukunamathela ekubekezeleni okuchazwe kuThebula 3 le-EN10210-2.
