Kwicandelo lemizi-mveliso eliphuhlileyo nelilawulwayo eYurophu, ukusebenza, ukuthembeka, kunye nokuthobela izinto zezona zinto zibalulekileyo. Phakathi kwezinto ezininzi ezibalulekileyo, ityhubhu yentsimbi engenamthungo ye-EN 10216 S355J2H, eyaziwa ngeempawu zayo ezintle ngokubanzi, iye yaba lukhetho olukhethwayo kumashishini aliqela aphambili, ukusuka kwiziseko zamandla ukuya ekuvelisweni koomatshini abanzima. Eli nqaku liphonononga iimpawu zale ntsimbi, imigangatho eyilandelayo, kunye nokusetyenziswa kwayo ngokubanzi kwimarike yaseYurophu.

Ukuqonda iMigangatho kunye nezinto ezisetyenzisiweyo: EN 10216 kunye ne-S355J2H

Okokuqala, kubalulekile ukuqonda intsingiselo yegama layo:

•I-EN 10216: Olu luluhlu olusemgangathweni lwaseYurophu oluchaza ngokukodwa iimeko zokuhanjiswa kobuchwephesha beetyhubhu zentsimbi ezingenamthungo ngeenjongo zoxinzelelo. Lo mgangatho uqinisekisa ukuba iityhubhu zigcina iimpawu zazo zoomatshini kumaqondo obushushu aphezulu, nto leyo ezenza zifaneleke kwizixhobo zoxinzelelo. Iinguqulelo zamva nje zithathelwe indawo zizinto ezifana ne-EN 10216-1 kunye ne-EN 10216-2, kodwa umgangatho we-S355J2H kunye neemfuno zawo ziye zadluliselwa phambili.

•S355J2H:

◦S: Imele "intsimbi yolwakhiwo".

◦355: Ibonisa amandla amancinci okuvelisa angama-355 Megapascals kubushushu begumbi, oko kuthetha ukuba inika ukumelana okuhle kakhulu nokuguquguquka kunye nomthamo wokuthwala umthwalo.

◦I-J2: Imele udidi lwe-Impact Toughness. Ibonisa ukuba uvavanyo lwe-Charpy V-notch impact lwenziwa kwi--20°C kwaye ihlangabezana neemfuno ezithile zokufunxa amandla. Oku kuqinisekisa ukuba izinto zigcina ukumelana okuhle nokuqhekeka okubuthathaka nokuba zikwindawo ebandayo, nto leyo ebalulekileyo ekufakweni ngaphandle kwimimandla efana neMantla Yurophu.

◦H: Imele "Imeko Eqhelekileyo". Oku kuthetha ukuba ityhubhu yentsimbi iye yafumana unyango lobushushu oluqhelekileyo ukuze iphucule isakhiwo sengqolowa, iphucule isakhiwo se-microstructure, ngaloo ndlela iphucule iimpawu zayo zoomatshini kunye nokuqina, okwenza ukuba ifane kwaye izinzile.

Ngamafutshane, i-EN 10216 S355J2H yityhubhu yentsimbi engenamthungo eqhelekileyo enamandla aphezulu, ukuqina okugqwesileyo kobushushu obuphantsi, kunye nokuthembeka, eyenzelwe ngokukodwa uxinzelelo kunye neendawo ezinoxinzelelo oluphezulu.

Iindawo eziPhambili zoSetyenziso kwiMarike yaseYurophu

Iimpawu zeetyhubhu ze-S355J2H ezingenamthungo zizenza zilungele iimfuno eziphezulu zokhuseleko, ukusebenza kakuhle, kunye nokuzinza kushishino lwaseYurophu. Iindawo eziphambili zokusetyenziswa kwazo ziquka:

1. Icandelo laMandla kunye naMandla

•Ioyile negesi: Isetyenziswa kwiipayipi zenkqubo, imigca yokuqokelela, imikhumbi yoxinzelelo, kunye neetyhubhu zebhoyila kumaqonga aselunxwemeni nawaselunxwemeni. Ukumelana kwayo noxinzelelo kunye nokusebenza kwayo kumaqondo obushushu aphantsi kubalulekile ekuphatheni iihydrocarbon ezinokutsha neziqhumayo.

•Amandla obushushu kunye nokuFudumeza kweSithili: Isetyenziswa kakhulu kwii-superheaters, ii-reheaters, kunye neetyhubhu ze-economizer zeebhoyila zesikhululo samandla, kunye nemigca ephambili yeenkqubo zokufudumeza zesithili sasezidolophini. Iyakwazi ukumelana nemiphumo yexesha elide yomphunga wobushushu obuphezulu kunye noxinzelelo oluphezulu.

•Amandla Avuselelekayo: Ezi payipi zoxinzelelo ziyafuneka nakwizityalo zamandla zebhayomass nakwezinye iiprojekthi ze-geothermal.

2. Ulwakhiwo kunye neZiseko zoPhuhliso

•Ukusetyenziswa kweZakhiwo Ezinzima: Isetyenziselwa iintsika zokuxhasa kunye nezakhiwo ezithwala imithwalo ebalulekileyo kwizakhiwo ezinkulu ezifana neenkundla zemidlalo, izikhululo zeenqwelo-moya, iibhulorho, kunye nezityalo zoshishino. Amandla ayo aphezulu avumela uyilo lwezakhiwo ezikhaphukhaphu kodwa ezomeleleyo.

•Oomatshini Bokwakha: Basebenza njengeebhareli zesilinda zehydraulic kunye nezixhobo zokwakha izixhobo ezinzima ezifana nee-excavators kunye nee-cranes, ekufuneka zinyamezele uxinzelelo olukhulu olutshintshanayo kunye nemithwalo yempembelelo.

3. Amashishini eeKhemikhali kunye neeNkqubo

•Isetyenziswa ekwenzeni ii-reactors, ii-heat exchangers, iikholamu, kunye neenkqubo zemibhobho apho izixhobo zihlala zisingatha imidiya ebolayo okanye eyingozi phantsi kobushushu obuphezulu kunye noxinzelelo. Ukuthembeka kunye nokungaguquguquki kwe-S355J2H kubalulekile ekuqinisekiseni ukusebenza ngokukhuselekileyo.

4. Ezinye izicelo zemizi-mveliso

•Isetyenziselwa ukuvelisa iisilinda zegesi zeegesi ezixinzelelweyo (umz., iigesi zoshishino, ioksijini yezonyango) phantsi kwemigaqo engqongqo ye-EU.

•Iityhubhu ezichanekileyo ezingenamthungo zokuthutha ulwelo olunoxinzelelo oluphezulu okanye njengezixhobo zoomatshini (umz., izindlu zeebheringi).

Izinto Eziphambili Eziqhuba Impumelelo Yalo KwiMarike YaseYurophu

1. Ukuthobela noKhuseleko lweMithetho: Umgangatho we-EN 10216 uhambelana ngokusondeleyo ne-European Pressure Equipment Directive (PED 2014/68/EU). Ukusebenzisa izixhobo ezihambelana nalo mgangatho kuyimfuneko esisiseko kubavelisi ukuba babeke izixhobo ngokusemthethweni kwimarike yaseYurophu, apho i-S355J2H inika ubungqina obuqinileyo bokuthobela.

2. Iipropati Ezibalaseleyo Zoomatshini: Indibaniselwano efanelekileyo yamandla nokuqina ivumela ukuba ikwazi ukumelana neemeko zemozulu ezahlukeneyo zaseYurophu kunye neendawo zoshishino ezifuna amandla.

3. Umgangatho kunye nokulandeleka: Abavelisi baseYurophu kunye nabasebenzisi bokugqibela bayayixabisa kakhulu isiqinisekiso somgangatho. Umgangatho we-EN 10216 uyalela ulawulo olungqongqo lwemveliso, uvavanyo, kunye nesatifikethi, ukuqinisekisa umgangatho ogqwesileyo rhoqo kunye nokulandeleka ngokupheleleyo kwibhetshi nganye yezixhobo.

4. Uthotho lweeNkonzo eziQhelekileyo kunye nobuGcisa: IYurophu iqhayisa ngabavelisi beetyhubhu zentsimbi abaphambili kwihlabathi (abafana neTenaris, iVallourec, kunye nabanye abanokubakho okukhulu) kunye neenethiwekhi zokusasaza, ezikwaziyo ukubonelela ngeetyhubhu ze-S355J2H ngokuzinzileyo kwiinkcukacha ezahlukeneyo kunye nokubonelela ngenkxaso yobugcisa epheleleyo.

Isiphelo

Ityhubhu yentsimbi engenamthungo ye-EN 10216 S355J2H ayisiyonto nje ethengiswayo; "ngumthambo" kunye "nomqolo" weziseko zoshishino zanamhlanje zaseYurophu. Impumelelo yayo ivela kudibaniso olugqibeleleyo: inkqubo esemgangathweni yaseYurophu ecacileyo umgangatho wayo ophezulu, kunye neempawu zayo zamandla aphezulu, ubulukhuni obuphezulu, kunye nokuthembeka okuphezulu ezihlangabezana ngokuchanekileyo neemfuno ezingqongqo zecandelo lezoshishino eziphambili zaseYurophu. Njengoko iYurophu iqhubeka nokutyala imali kutshintsho lwamandla, ukuphuculwa kweziseko zobugcisa, kunye nokuvelisa izinto ezintsha, ityhubhu yentsimbi engenamthungo ye-S355J2H ngokuqinisekileyo iya kuhlala iyinto ebalulekileyo efunekayo, ixhasa okwangoku nakwikamva leshishini laseYurophu.
