Uhlolojikelele lwe-EN 10219 S355J0H

I-EN 10219 S355J0Hyin aezishiselwe ezibandayoipayipi lensimbi lesakhiwo elingenalutho ukuzeI-EN 10219, ngamandla amancane okukhiqiza we355 MPa(ukujiya kodonga lwepayipi ≤ 16 mm) kanye namandla okuthonya okungenani27 J ngo-0°C.

Ekhiqizwa kusetshenziswa i-welding kagesi noma amasu we-arc welding angaphansi kwamanzi ngaphandle kwesidingo sokwelashwa kokushisa okulandelayo, afaneleka ezinhlobonhlobo zezinhlelo zokusebenza zesakhiwo sezakhiwo nezobunjiniyela, okuhlanganisa izingxenye ezibalulekile zesakhiwo njengezinqwaba zokusekelwa kwesisekelo.

I-BS EN 10219 iyi-European Standard EN 10219 eyamukelwa yi-UK.

Ukwahlukaniswa Komumo

Kuhlanganisa ashiselwe abandayoisiyingi, isikwele, unxande, kanye ne-ellipticalizingxenye ezingenalutho zesakhiwo.

CFCHS = ingxenye eyindilinga eyindilinga eyakhiwe ngendlela ebandayo;

CFRHS = isikwele esakhiwe ngokubanda noma ingxenye eyigodi engunxande;

Sisebenza ngokukhethekile ekuhlinzekeni isigaba esiphezulu esiyindilinga esingenalutho (I-CHS) ipayipi lensimbi ukuhlangabezana nezidingo zakho ezihlukahlukene zobunjiniyela.

Ububanzi besayizi

Ukujiya kodonga ≤40mm;

Isiyingi: Ububanzi bangaphandle bufika ku-2500 mm;

Inqubo Yokukhiqiza

Izingxenye ezingenalutho zesakhiwo zizokwakhiwa ngui-welding kagesi noma i-arc welding engaphansi kwamanzi (SAW).

I-EN 10219 izingxenye ezingenalutho zizolethwa zakhiwe ngendlela ebandayo ngaphandle kokwelashwa kokushisa okulandelayo, kodwa ama-welds angase abe esimweni esishiselwe noma esiphathwe ngokushisa.

Uma kusetshenziswa ubuchwepheshe bokushisela be-arc obungaphansi kwamanzi, bungahlukaniswa ngokuthiI-LSAW(SAWL) (Longitudinal Submerged Arc Welding) kanyeI-SSAW(HSAW)(Spiral Submerged Arc Welding) kuye ngokuthi i-weld seam ibheke ngakuphi.

I-LSAWkunezinzuzo ezibalulekile ekukhiqizeniububanzi obukhulufuthiamapayipi ensimbi anezindonga eziwugqinsifuthi ifaneleka ngokukhethekile izimo zohlelo lokusebenza lapho amandla aphezulu, ikhwalithi, nobukhulu obunembayo budingeka ngokuqinile.

JCOEiyinqubo ebaluleke kakhulu futhi emele ekukhiqizeni ipayipi yensimbi ye-LSAW.Igama lenqubo livela ezinyathelweni ezine eziyinhloko zenqubo yokwenza amapayipi: Ukwakhiwa kwe-J, Ukwakhiwa kwe-C, Ukwakhiwa kwe-O, kanye Nokwandisa.

Singabakhiqizi nabahlinzeki bepayipi lensimbi yensimbi esezingeni eliphezulu abavela eChina, futhi siphinde sibe nesitoko sepayipi sensimbi esingenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!

Ukuchezuka kokuhlaziywa komkhiqizo kusukela kumikhawulo ecaciswe ekuhlaziyweni kokusakaza kuzohambisana nezidingo ezingezansi.

I-EN 10219 Ukuchezuka ekwakhekeni kwamakhemikhali

I-EN 10219 S355J0H Ukusebenza Komshini

Ukunciphisa ingcindezi ngaphezu kuka-580 °C noma isikhathi esingaphezu kwehora elilodwa kungase kuholele ekuwohlokeni kwezakhiwo zemishini.

Ukuhlolwa kwe-tensile kuzokwenziwa ngokuhambisana ne-EN 10002-1.

Ukuhlolwa komthelela kuzokwenziwa ngokuhambisana ne-EN 10045-1.

a Izakhiwo zomthelela ziqinisekiswa kuphela uma Inketho 1.3 icacisiwe.

c Ngosayizi wezigaba D/T < 15 (isiyingi) kanye (B+H)/2T < 12,5 (isikwele nonxande) ubude obuncane buncishiswa ngo-2.

d Ngobukhulu obungu-< 3 mm bona u-9.2.2.

e Ngezakhiwo zomthelela zezingxenye zokuhlola ezincishisiwe bheka 6.7.2.

Amanothi: Ukuhlolwa komthelela akudingekile uma ubukhulu obucacisiwe bungu-<6mm.

I-EN 10219 SAW Ukuhlolwa Okungonakali

Ama-welds asezigabeni ezingaphansi kwe-arc ashiselwe okungenalutho azohlolwa ngokuhambisana ne-EN 10246-9 ukuze uthole isigaba sokwamukela i-U4 noma ngeradiographically ngokuhambisana ne-EN 10246-10 yesigaba sekhwalithi yesithombe esingu-R2.

Ukuhlolwa kwe-NDT(RT).

Ukuhlolwa kwe-NDT(UT).

Ukuhlolwa kwe-Hydrostatic

Sisebenzisa izinhlobonhlobo zamasu okuhlola angonakali kanye nokuhlolwa kwengcindezi ye-hydrostatic ukuze siqinisekise amandla nokuqina kwepayipi ngalinye.Sinikeza amakhasimende ethu imikhiqizo yamapayipi ensimbi ehlangabezana nezindinganiso eziphakeme kakhulu zokuphepha nokuqinisekiswa kwekhwalithi.

Ukushisela

Amashubhu esigaba esingenalutho enziwe ngokuya nge-EN 10219 ayashiseleka.

Lapho kushiselwa, ukuqhekeka okubandayo endaweni yokushisela kuyingozi enkulu njengoba ukushuba, izinga lamandla, kanye ne-CEV yomkhiqizo kukhuphuka.Ukuqhekeka okubandayo kubangelwa inhlanganisela yezinto ezimbalwa:

amazinga aphezulu e-hydrogen e-diffusable ensimbi yokushisela;

isakhiwo esinama-brittle endaweni ethinteke ukushisa;

ukugxila okubalulekile kokucindezeleka okuqinile endaweni ehlanganisiwe eshiselwe.

i-hot-dip Galvanization

I-EN 10219 amapayipi ensimbi afaneleka ukugalela amadiphu ashisayo.Ukukhetha kungenziwa ngokuya ngezidingo zangempela.

Ukubukeka Kobuso

Izoba nendawo ebushelelezi ehambisana nendlela yokukhiqiza esetshenzisiwe;amaqhuqhuva, ama-voids, noma ama-longitudinal grooves angajulile ngenxa yenqubo yokukhiqiza avumelekile inqobo nje uma ukujiya kwawo okusele kuvumelana nokubekezelelwa.

Ukulimala okungaphezulu kungasuswa ngokugaya, inqobo nje uma ubukhulu besigaba esingenalutho esilungisiwe singekho ngaphansi kobukhulu obuncane obuvunyelwe obucaciswe ku-EN 10219-2.

4. Imishini yokwakha: Ingasetshenziselwa ukukhiqiza amabakaki nezingxenye zemishini ehlukahlukene yokwakha.

5. Izinsiza zomphakathi: njengama-bleachers ezinkundleni zemidlalo kanye nezinye izinhlaka ezisekela izikhungo ezinkulu zomphakathi.

I-EN 10219 S355J0H Equivalent Material

I-EN 10210 S355J0H: Isigaba esingenalutho sezakhiwo ezishiselwe i-thermoforming.Nakuba ngokuyinhloko isetshenziselwa i-thermoforming, ukwakheka kwayo kwamakhemikhali kanye nezakhiwo zemishini zifana nalezo ze-S355J0H futhi zingasetshenziswa njengento enhle efanayo.

I-ASTM A500 Ibanga C: Isetshenziswa ekwenzeni amashubhu ayindilinga ashiselwe noma angenamthungo awakheke ngendlela ebandayo, ayizikwele, nawunxande ukuze kusetshenziswe izakhiwo.I-ASTM A500 IBanga C ihlinzeka ngesivuno esifanayo namandla aqinile ezakhiwo zezakhiwo nezomshini.

I-CSA G40.21 350W: Lokhu ukucaciswa kwe-Canadian Standards Association okuhlanganisa amamaki amaningi ensimbi yesakhiwo.Insimbi yezinga elingu-350W inesivuno esifanayo namandla aqinile ku-S355J0H.

I-JIS G3466 STKR490: Lena into yeshubhu eyisikwele futhi engunxande ukuze isetshenziswe ngokwesakhiwo njengoba kucaciswe ku-Japanese Industrial Standard (JIS).Ifanele izakhiwo zokwakha kanye nezinhloso zemishini.

Izinzuzo Zethu

Kusukela yasungulwa ngo-2014,Insimbi ye-Botopisibe ngumphakeli ohamba phambili wepayipi lensimbi ye-carbon eNyakatho yeChina, elaziwa ngomsebenzi omuhle kakhulu, imikhiqizo yekhwalithi ephezulu, nezixazululo ezibanzi.

Le nkampani inikeza izinhlobonhlobo zamapayipi ensimbi ye-carbon nemikhiqizo ehlobene, okuhlanganisa ipayipi lensimbi engenamthungo, i-ERW, i-LSAW, ne-SSAW, kanye nohlu oluphelele lokufakwa kwamapayipi nama-flange.Imikhiqizo yayo ekhethekile ihlanganisa ama-alloys asezingeni eliphezulu kanye nezinsimbi ezingenasici ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene wamapayipi.
