Emkhakheni wezimboni othuthuke kakhulu futhi olawulwayo eYurophu, ukusebenza, ukuthembeka, kanye nokuhambisana nezinto zokwakha kubaluleke kakhulu. Phakathi kwezinto eziningi ezibalulekile, ishubhu lensimbi elingenamthungo le-EN 10216 S355J2H, elidume ngezakhiwo zalo ezinhle kakhulu, seliye laba ukukhetha okuthandwayo ezimbonini eziningana eziyinhloko, kusukela engqalasizinda yamandla kuya ekukhiqizweni kwemishini esindayo. Lesi sihloko sihlola izici zale nsimbi, amazinga elandela wona, kanye nokusetshenziswa kwayo okubanzi emakethe yaseYurophu.

Ukuqonda Izinga kanye Nezinto Ezisetshenziswayo: EN 10216 kanye ne-S355J2H

Okokuqala, kubalulekile ukuqonda incazelo yegama layo:

•I-EN 10216: Lolu uchungechunge olujwayelekile lwaseYurophu oluchaza ngqo izimo zokulethwa kobuchwepheshe zamapayipi ensimbi angenamthungo ngezinjongo zokucindezela. Leli zinga liqinisekisa ukuthi amapayipi agcina izakhiwo zawo zemishini emazingeni okushisa aphezulu, okwenza afaneleke imishini yokucindezela. Izinguqulo zakamuva zithathelwe indawo yizingxenye ezifana ne-EN 10216-1 kanye ne-EN 10216-2, kodwa izinga le-S355J2H kanye nezidingo zalo kuqhutshekwe phambili.

•I-S355J2H:

◦S: Imele "Insimbi Yokwakheka".

◦355: Ibonisa amandla okukhiqiza okungenani angu-355 Megapascals ekushiseni kwegumbi, okusho ukuthi inikeza ukumelana okuhle kakhulu nokuguquguquka kanye nomthamo wokuthwala umthwalo.

◦I-J2: Imele izinga lokuqina kwe-Impact. Kusho ukuthi ukuhlolwa komthelela we-Charpy V-notch kwenziwa ku--20°C futhi ihlangabezana nezidingo ezithile zokumuncwa kwamandla. Lokhu kuqinisekisa ukuthi izinto zigcina ukumelana okuhle nokuqhekeka okuqhekekayo ngisho nasezindaweni ezibandayo, okubalulekile ekufakweni kwangaphandle ezifundeni ezifana neNyakatho Yurophu.

◦H: Imele "Isimo Esijwayelekile". Lokhu kusho ukuthi ithubhu lensimbi liye labhekana nokwelashwa kokushisa okuvamile ukuze kulungiswe isakhiwo sokusanhlamvu, kuthuthukiswe isakhiwo esincane, ngaleyo ndlela kuthuthukiswe izakhiwo zalo zomshini kanye nokuqina, okwenza kube okufanayo futhi kuzinze.

Ngamafuphi, i-EN 10216 S355J2H iyishubhu yensimbi engenamthungo evamile enamandla aphezulu, ukuqina okuhle kakhulu kwezinga lokushisa eliphansi, kanye nokuthembeka, eyenzelwe ngqo izindawo zokucindezela kanye nokucindezeleka okuphezulu.

Izindawo Eziyinhloko Zokusebenza Emakethe YaseYurophu

Izakhiwo zamashubhu angenamthungo e-S355J2H ziwenza afaneleke kahle ezidingweni eziphakeme zokuphepha, ukusebenza kahle, kanye nokusimama embonini yaseYurophu. Izindawo zawo eziyinhloko zokusetshenziswa zifaka:

1. Umkhakha Wezamandla Namandla

•Uwoyela negesi: Isetshenziswa ekucubunguleni amapayipi, imigqa yokuqoqa, imikhumbi yokucindezela, kanye namapayipi e-boiler kumapulatifomu asogwini nasogwini. Ukumelana kwayo nokucindezela kanye nokusebenza kwayo emazingeni okushisa aphansi kubalulekile ekuphatheni ama-hydrocarbon avuthayo naqhumayo.

•Amandla Okushisa Nokushisa Kwesifunda: Kusetshenziswa kabanzi kuma-superheater, ama-reheater, nama-economizer tubes ama-boiler eziteshi zamandla, kanye nemigqa eyinhloko yezinhlelo zokushisa zesifunda sasemadolobheni. Kungamelana nemiphumela yesikhathi eside yesitimu sokushisa okuphezulu kanye nomfutho ophezulu.

•Amandla Avuselelekayo: Amapayipi anjalo okucindezela ayadingeka nasezitshalweni zamandla ze-biomass nakwamanye amaphrojekthi e-geothermal.

2. Ukwakhiwa kanye Nengqalasizinda

•Izicelo Ezinzima Zesakhiwo: Isetshenziselwa izinsika zokusekela kanye nezakhiwo ezithwala umthwalo oyinhloko ezakhiweni ezinkulu njengezinkundla zemidlalo, izikhumulo zezindiza, amabhuloho, kanye nezitshalo zezimboni. Amandla ayo aphezulu avumela ukwakheka kwezakhiwo ezilula kodwa eziqinile.

•Imishini Yokwakha: Isebenza njengemiphongolo yesilinda ye-hydraulic kanye nezingxenye zesakhiwo semishini esindayo njengemishini yokumba kanye nama-crane, okumele ibhekane nokucindezeleka okukhulu okushintshashintshayo kanye nemithwalo yomthelela.

3. Izimboni Zamakhemikhali Nezinqubo

•Isetshenziswa ekukhiqizeni ama-reactor, ama-heat exchanger, amakholomu, kanye nezinhlelo zokucubungula amapayipi lapho imishini ivame ukuphatha khona izinto ezigqwalisayo noma eziyingozi ngaphansi kokushisa okuphezulu kanye nengcindezi. Ukuthembeka kanye nokuvumelana kwe-S355J2H kubalulekile ekuqinisekiseni ukusebenza okuphephile.

4. Ezinye Izicelo Zezimboni

•Isetshenziselwa ukukhiqiza amasilinda egesi amagesi acindezelwe (isb., amagesi ezimboni, umoya-mpilo wezokwelapha) ngaphansi kwemithetho eqinile ye-EU.

•Amashubhu angenamthungo aqondile okuthutha uketshezi olunomfutho ophezulu noma njengezingxenye zemishini (isb., izindawo zokubeka amabheringi).

Izici Eziyinhloko Eziqhuba Impumelelo Yalo Emakethe YaseYurophu

1. Ukuthobela Nokuphepha Kwemithetho: Izinga le-EN 10216 lihambisana eduze ne-European Pressure Equipment Directive (PED 2014/68/EU). Ukusebenzisa izinto ezihambisana naleli zinga kuyimfuneko eyisisekelo yokuthi abakhiqizi babeke imishini ngokusemthethweni emakethe yaseYurophu, lapho i-S355J2H inikeza ubufakazi obuqinile bokuthobela imithetho.

2. Izakhiwo Ezinhle Kakhulu Zemishini: Inhlanganisela efanele yamandla nokuqina ivumela ukuthi ikwazi ukubhekana nezimo zezulu ezahlukahlukene zaseYurophu kanye nezindawo zezimboni ezidingayo.

3. Ikhwalithi Nokulandelela: Abakhiqizi baseYurophu kanye nabasebenzisi bokugcina bayakwazisa kakhulu ukuqinisekiswa kwekhwalithi. Izinga le-EN 10216 lidinga ukulawulwa okuqinile kokukhiqiza, ukuhlolwa, kanye nesitifiketi, ukuqinisekisa ikhwalithi enhle njalo kanye nokulandelela okugcwele kweqoqo ngalinye lezinto.

4. Uchungechunge Lokuhlinzeka Nobuchwepheshe Obuvuthiwe: IYurophu ineqhaza ngabakhiqizi bamashubhu ensimbi abahamba phambili emhlabeni (njengeTenaris, iVallourec, nabanye abakhona kakhulu) kanye namanethiwekhi okusabalalisa, abakwazi ukuhlinzeka ngamashubhu e-S355J2H ngokuzinzile ngezincazelo ezahlukahlukene kanye nokunikeza ukwesekwa kobuchwepheshe okuphelele.

Isiphetho

Ishubhu lensimbi elingenamthungo le-EN 10216 S355J2H lingaphezu nje kwempahla; "liyi-artery" kanye "nomgogodla" wengqalasizinda yezimboni yanamuhla yaseYurophu. Impumelelo yalo ivela ekuhlanganisweni okuphelele: uhlelo oluqinile lwezinga laseYurophu oluchaza ikhwalithi yalo ephezulu, kanye nezakhiwo zalo zangaphakathi zamandla aphezulu, ukuqina okuphezulu, kanye nokuthembeka okuphezulu okuhlangabezana ngqo nezidingo eziqinile zemikhakha yezimboni eyinhloko yaseYurophu. Njengoba iYurophu iqhubeka nokutshala imali ekushintsheni kwamandla, ukuthuthukiswa kwengqalasizinda, kanye nokusungula izinto ezintsha, ishubhu lensimbi elingenamthungo le-S355J2H ngokungangabazeki lizohlala liyinto ebalulekile ebalulekile, lisekela okwamanje nekusasa lemboni yaseYurophu.
