I-EN 10210 S355J2Hiyinsimbi yesakhiwo esingenalutho esiqediwe ngokushisa ngokushoI-EN 10210enamandla okukhiqiza okungenani angu-355 MPa (ngobukhulu bodonga ≤ 16 mm) kanye nezakhiwo ezinhle zokuthinteka emazingeni okushisa aphansi afinyelela ku--20°C, okwenza kube kuhle ukusetshenziswa ezinhlotsheni eziningi zezakhiwo nezobunjiniyela.
Yebo, i-EN 10210 =I-BS EN 10210.
I-BS EN 10210 kanye ne-EN 10210 ziyafana ngokuqukethwe kobuchwepheshe futhi zombili zimelela amazinga aseYurophu okuklama, ukukhiqiza, kanye nezidingo zezingxenye ezingenalutho ezakhiwe ngesakhiwo esinokushisa.
I-BS EN 10210 inguqulo eyamukelwa e-UK, kanti i-EN 10210 iyindinganiso yaseYurophu yonke. Izinhlangano ezahlukene zokulinganisa zikazwelonke zingase ziqale indinganiso ngezifinyezo ezithile zikazwelonke, kodwa okuqukethwe okuyinhloko kwale ndinganiso kuhlala kungaguquguquki.
Izingxenye ezingenalutho zingahlukaniswa njengendilinga, isikwele noma unxande, noma i-elliptical.
Futhi ngoba kuyinqubo eqediwe eshisayo ngokuhambisana ne-EN 10210, isifinyezo esilandelayo singasetshenziswa.
I-HFCHS= izingxenye ezingenalutho eziqediwe ezishisayo neziyindilinga；
I-HFRHS= izingxenye ezingenalutho eziqediwe eziyisikwele noma eziyisikwele;
I-HFEHS= izingxenye ezingenalutho eziqediwe ezi-elliptical ezishisayo.
Isiyingi: Ububanzi bangaphandle obufika ku-2500 mm;
Ubukhulu bodonga bufika ku-120 mm.
Vele, ayikho indlela yokukhiqiza amashubhu alolu hlobo kanye nobukhulu bodonga uma kusetshenziswa inqubo yokushisela ye-ERW.
I-ERW ingakhiqiza amashubhu afinyelela ku-660mm anobukhulu bodonga obungu-20mm.
Insimbi ingakhiqizwa ngokusebenzisai-seamless noma i-weldinginqubo.
Phakathi kweizinqubo zokushisela, izindlela ezivamile zokushisela zifaka phakathiI-ERW(ukushisela ukumelana kagesi) kanyeI-SAW(ukushisela i-arc okucwiliswe emanzini).
Phakathi kwabanye,I-ERWkuyindlela yokushisela ehlanganisa izingxenye zensimbi ndawonye ngokushisa nokucindezela okumelanayo. Le ndlela isebenza ezintweni eziningi kanye nobukhulu futhi yenza inqubo yokushisela isebenze kahle.
I-SAWNgakolunye uhlangothi, kuyindlela yokushisela esebenzisa i-granular flux ukumboza i-arc, ehlinzeka ngokungena okujulile kanye nekhwalithi engcono yokushisela futhi ifaneleka kakhulu ekushiseleni amapuleti aminyene.
Okulandelayo, inqubo ye-ERW, okuyindlela yokukhiqiza esebenza kahle kakhulu esetshenziswa kabanzi ukukhiqiza amashubhu ensimbi ahlukahlukene kanye namaphrofayili.
Kufanele kuqashelwe ukuthi ezingxenyeni ezingaxutshiwe nezingenazinhlayiya ezinhle ezenziwe ngenqubo yokushisela, ukulungisa ama-weld akuvunyelwe ngaphandle kokushisela i-arc engaphansi kwamanzi.
Ikhwalithi JR, JO, J2 kanye ne-K2 - iqediwe kahle,
Amandla okukhiqiza amancane kakhulu epayipi lensimbi le-S355J2H awazinzile, azoshintsha ngobukhulu obuhlukile bodonga.
Ngokukhethekile, amandla okukhiqiza e-S355J2H abekwa ngokwezinga lapho ubukhulu bodonga bungaphansi noma bulingana no-16mm, kodwa lapho ubukhulu bodonga bukhula, amandla okukhiqiza azoncishiswa, ngakho-ke akuwona wonke amapayipi ensimbi e-S355J2H angafinyelela amandla okukhiqiza amancane angu-355MPa.

Ipayipi lensimbi le-S355J2H liyipayipi lensimbi eliqinile kakhulu elinokusebenza kahle kokushisela kanye nokuqina komthelela ophansi, ngakho-ke linokusetshenziswa okubanzi emikhakheni eminingana yezimboni.
1. Ukwakhiwa: isetshenziswa emabhulohweni, emibhoshongweni, ezakhiweni zohlaka, ezokuthutha ngesitimela, ezitimeleni ezingaphansi komhlaba, ozimele bophahla, amaphaneli odonga, nezinye izakhiwo zesakhiwo.
2. Uhlelo lwamapayipi: Isetshenziswa njengamapayipi okuthutha uketshezi, ikakhulukazi ezimweni lapho kudingeka khona amandla aphezulu kanye nokumelana nengcindezi.
3. Ubunjiniyela bezolwandle kanye nolwandle: esetshenziswa ezakhiweni zemikhumbi, amapulatifomu asogwini lolwandle, kanye nezinye izakhiwo zobunjiniyela basolwandle.
4. Imboni yamandla: esetshenziswa ezindaweni zamandla njengemibhoshongo yamandla omoya, amapulatifomu okumba uwoyela, kanye namapayipi.
5. Imithambo yokucindezela: isetshenziswa ekwakhiweni kwemithambo yokucindezela ngokuhambisana nezidingo ezithile zokushisela kanye nokwelashwa kokushisa.
6. Imboni yezimayini: esetshenziselwa izingxenye zesakhiwo sezakhiwo zokusekela imayini, izinhlelo zokuhambisa, kanye nemishini yokucubungula i-ore.
Ipayipi elingenalutho noma i-Black / Varnish coating (eyenziwe ngokwezifiso);
ngezinqwaba noma ezikhululekile;
