I-EN 10219 S355J0Hkuyintookuhlanganisiwe okwenziwe ngokubandayoipayipi lensimbi elingenalutho eliyisakhiwoI-EN 10219, ngamandla amancane okukhiqiza355 MPa(ubukhulu bodonga lwamapayipi ≤ 16 mm) kanye namandla okushaya okungenani27 J ku-0°C.
Njengoba zakhiwe kusetshenziswa amasu okushisela kagesi noma ukushisela i-arc ngaphansi kwamanzi ngaphandle kwesidingo sokwelashwa kokushisa okulandelayo, zifanelekela ukusetshenziswa okubanzi kwezakhiwo zokwakha nezobunjiniyela, okuhlanganisa izingxenye ezibalulekile zesakhiwo njengezinqwaba zokusekela isisekelo.
I-BS EN 10219 iyi-European Standard EN 10219 eyamukelwe yi-UK.
Kufaka phakathi okuhlanganisiwe okwenziwe ngokubandayoisiyingi, isikwele, unxande, kanye ne-ellipticalizingxenye ezingenalutho ezakhiweni.
I-CFCHS = ingxenye engenalutho eyindilinga eyakhiwe ngokubandayo;
I-CFRHS = ingxenye eyisikwele noma engunxande eyakhiwe ngokubandayo;
Singochwepheshe ekuhlinzekeni ngesigaba esingenalutho esiyindilinga esisezingeni eliphezulu (I-CHS) ipayipi lensimbi ukuze lihlangabezane nezidingo zakho ezahlukene zobunjiniyela.
Ubukhulu bodonga ≤40mm;
Isiyingi: Ububanzi bangaphandle obufika ku-2500 mm;
Izingxenye ezingenalutho ezakhiweni kumele zenziwe yi-ukushisela ngogesi noma ukushisela nge-arc engaphansi komhlaba (SAW).
Izingxenye ezingenalutho ze-EN 10219 kufanele zilethwe zibanda ngaphandle kokwelashwa kokushisa okulandelayo, kodwa ama-weld angase abe sesimweni sokushiswa noma sokuphathwa kokushisa.
Uma kusetshenziswa ubuchwepheshe bokushisela i-arc engaphansi kwamanzi, bungahlukaniswa ngezigabaI-LSAW(I-SAWL) (Ukushisela i-Arc Engaphansi Kwe-Longitudinal) kanyeI-SSAW(I-HSAW)(Ukushisela kwe-Arc Okucwiliswe Nge-Spiral) kuye ngokuthi umthungo wokushisela uqondiswa kanjani.
I-LSAWinezinzuzo ezibalulekile ekukhiqizweni kweububanzi obukhulufuthiamapayipi ensimbi anodonga olujiyilefuthi ifaneleka kakhulu ezimweni zokusetshenziswa lapho kudingeka khona amandla aphezulu, ikhwalithi, kanye nobukhulu obuqondile.
I-JCOEkuyinqubo ebaluleke kakhulu futhi emele ekukhiqizweni kwepayipi lensimbi le-LSAW. Igama lenqubo livela ezinyathelweni ezine eziyinhloko enkambisweni yokwenza ipayipi: ukwakha u-J, ukwakha u-C, ukwakha u-O, kanye nokwandisa.
Singumkhiqizi kanye nomhlinzeki wamapayipi ensimbi yekhabhoni ashiselwe ngekhwalithi ephezulu avela eShayina, futhi siphinde sibe ngumthengisi wamapayipi ensimbi angenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!
Ukuhlaziywa Kwabadlali
Ukuhlaziywa kwamakhemikhali kwezinto zokusetshenziswa zamapayipi ensimbi
S355J0H Inani eliphezulu lokulingana kwekhabhoni (i-CEV): 0.45%.
CEV = C + Mn/6 +(Cr + Mo + V)/5 + (Ni + Cu)/15.
Ukuhlaziywa Komkhiqizo
Ukuhlaziywa kokwakheka kwamakhemikhali kwezingxenye ezingenalutho eziqediwe
Ukuphambuka kokuhlaziywa komkhiqizo emikhawulweni echazwe ekuhlaziyweni kokusatshalaliswa kufanele kuhambisane nezidingo ezingezansi.
Ukunciphisa ukucindezeleka okungaphezu kuka-580 °C noma isikhathi esingaphezu kwehora elilodwa kungaholela ekuwohlokeni kwezakhiwo zemishini.
Ukuhlolwa kokudonsa kufanele kwenziwe ngokuhambisana ne-EN 10002-1.
Ukuhlolwa komthelela kufanele kwenziwe ngokuhambisana ne-EN 10045-1.
Izakhiwo zomthelela ziqinisekiswa kuphela uma inketho 1.3 icacisiwe.
c Kumasayizi esigaba D/T < 15 (isiyingi) kanye (B+H)/2T < 12,5 (isikwele nesiyingi) ubude obuncane buncishiswa ngo-2.
d Ubukhulu < 3 mm bheka 9.2.2.
e Ukuze uthole izakhiwo zomthelela wezingcezu zokuhlola zesigaba esincishisiwe bheka u-6.7.2.
Amanothi: Ukuhlolwa komthelela akudingeki uma ubukhulu obucacisiwe bungaphansi kuka-6mm.
Ama-weld asezigabeni ezimbozwe nge-arc engaphansi komhlaba afakwe imigodi kufanele ahlolwe ngokuhambisana ne-EN 10246-9 ukuze athole isigaba sokwamukelwa se-U4 noma nge-rayography ngokuhambisana ne-EN 10246-10 ukuze athole isigaba sekhwalithi yesithombe se-R2.

Ukuhlolwa Kwamanzi
Sisebenzisa izindlela ezahlukene zokuhlola ezingabhubhisi kanye nokuhlolwa kokucindezela kwe-hydrostatic ukuqinisekisa ukuqina nokuqina kwepayipi ngalinye. Sinikeza amakhasimende ethu imikhiqizo yepayipi yensimbi ehlangabezana nezindinganiso eziphakeme kakhulu zokuphepha nokuqinisekiswa kwekhwalithi.
Amashubhu ezingxenye ezingenalutho akhiqizwe ngokwe-EN 10219 ayashiselelwa.
Lapho kushiselwa, ukuqhekeka okubandayo endaweni yokushiselwa kuyingozi enkulu njengoba ukujiya, izinga lamandla, kanye ne-CEV yomkhiqizo kukhula. Ukuqhekeka okubandayo kubangelwa yinhlanganisela yezici eziningana:
amazinga aphezulu e-hydrogen esakazekayo ensimbini yokushisela;
isakhiwo esibuthakathaka endaweni ethintekile ekushiseni;
ukugxila okukhulu kokucindezeleka kokudonsa engxenyeni ehlanganisiwe.
Amapayipi ensimbi e-EN 10219 afanelekela ukugaya nge-hot dip. Ukukhetha kungenziwa ngokwezidingo zangempela.
Kufanele kube nobuso obubushelelezi obuhambisana nendlela yokukhiqiza esetshenzisiwe; amaqhubu, izikhala, noma imisele emide engajulile evela enkambisweni yokukhiqiza kuvunyelwe uma nje ukujiya kwayo okusele kungaphakathi kokubekezelelwa.
Amaphutha angaphezulu angasuswa ngokugaya, uma nje ubukhulu bengxenye engenalutho elungisiwe bungaphansi kobukhulu obuvunyelwe obuncane obuchazwe ku-EN 10219-2.

Ipayipi lensimbi le-EN 10219 S355J0H liyinto eqinile futhi engagqwali efanelekela kahle izakhiwo eziningi zokwakha nezobunjiniyela, okuhlanganisa nokusetshenziswa kwenqwaba yamapayipi.
1. Inqwaba Yamapayipi: Ipayipi lensimbi i-S355J0H lifaneleka kakhulu ukusetshenziswa njengezinqwaba zesisekelo ngenxa yamandla alo kanye nokumelana nokugqwala futhi lisetshenziswa kabanzi ekwakhiweni kwamachweba, amabhuloho, izisekelo zokwakha, kanye neminye imisebenzi edinga izisekelo ezijulile.
2. Izakhiwo zokwakha: Ivame ukusetshenziswa ezintweni ezifana nezakhiwo zamathambo, amakholomu asekelayo, kanye nemishayo yezakhiwo.
3. Ukuthuthwa kwepayipi: Ifaneleka kahle futhi ukusetshenziswa njengepayipi lokuthutha uwoyela negesi amabanga amade. Kodwa-ke, ivame ukumbozwa ukuze yandise impilo yesevisi, isib. 3LPE, FBE, galvanized, njll.
4. Imishini yokwakha: Ingasetshenziswa ukukhiqiza amabhuleki nezingxenye zemishini yokwakha eyahlukahlukene.
5. Izikhungo zomphakathi: njengezindawo zokubeka izingubo ezinkundleni zemidlalo kanye nezinye izakhiwo zokusekela izikhungo ezinkulu zomphakathi.
I-EN 10210 S355J0H: Ingxenye engenalutho yezakhiwo ezihlanganisiwe ze-thermoforming. Nakuba isetshenziswa kakhulu ekwenzeni i-thermoforming, ukwakheka kwayo kwamakhemikhali kanye nezakhiwo zayo zemishini kufana nokwe-S355J0H futhi ingasetshenziswa njengento elinganayo.
Ibanga C le-ASTM A500: Isetshenziswa ekwakhiweni kwamashubhu ahlanganisiwe noma angenamthungo abandayo abumbeke njengendilinga, isikwele, kanye nonxande ukuze kusetshenziswe izakhiwo. I-ASTM A500 Grade C inikeza amandla afanayo okukhiqiza kanye nokuthambekela kwezakhiwo zokwakha nezemishini.
I-CSA G40.21 350W: Lena incazelo ye-Canadian Standards Association ehlanganisa ububanzi bezinhlobo zensimbi ezakhiwe. Insimbi yezinga lika-350W inomkhiqizo ofanayo kanye namandla okunamathela njenge-S355J0H.
I-JIS G3466 STKR490: Lokhu kuyishubhu eliyisikwele neliyisikwele elisetshenziselwa ukwakheka njengoba kuchaziwe ku-Japanese Industrial Standard (JIS). Lifanele izakhiwo zokwakha kanye nezinjongo zemishini.
Selokhu yasungulwa ngo-2014,Insimbi yeBotopisibe ngumhlinzeki ohamba phambili wamapayipi ensimbi yekhabhoni eNyakatho yeShayina, eyaziwa ngenkonzo enhle kakhulu, imikhiqizo esezingeni eliphezulu, kanye nezixazululo eziphelele.
Le nkampani inikeza amapayipi ahlukahlukene ensimbi yekhabhoni kanye nemikhiqizo ehlobene nayo, kufaka phakathi ipayipi lensimbi elingenamthungo, i-ERW, i-LSAW, kanye ne-SSAW, kanye nohlu oluphelele lwezihlanganisi zamapayipi nama-flange. Imikhiqizo yayo ekhethekile ifaka phakathi ama-alloy ebanga eliphezulu kanye nezinsimbi ezingagqwali ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene amapayipi.
