Kukhuthala kwa khoma ≤40mm, M'mimba mwake wakunja ≤2500mm.
CFCHS ndi chidule cha gawo lozungulira lozungulira lokhala ndi ming'alu yozungulira.
Muyezo wa EN 10219 umaphatikizapo mitundu yosiyanasiyana ya chitsulo chopangidwa ndi mabowo, kuphatikizapo chozungulira, chapakati, chamakona anayi, ndi chozungulira, kuti chigwirizane ndi zofunikira zosiyanasiyana zogwiritsira ntchito.
Chitsulo cha BotopKampaniyi imagwira ntchito yopereka machubu achitsulo ozungulira okhala ndi dzenje m'makulidwe ndi njira zosiyanasiyana kuti agwirizane ndi ntchito zosiyanasiyana zamakampani, kuonetsetsa kuti zosowa za makasitomala athu zitha kukwaniritsidwa.
Kuyambira pomwe idakhazikitsidwa mu 2014,Chitsulo cha Botopwakhala kampani yotsogola yogulitsa mapaipi achitsulo cha kaboni kumpoto kwa China, yodziwika bwino chifukwa cha ntchito zabwino kwambiri, zinthu zapamwamba, komanso mayankho omveka bwino.
Kampaniyo imapereka mapaipi osiyanasiyana achitsulo cha kaboni ndi zinthu zina zokhudzana nazo, kuphatikizapoSMLS, ERW, LSAWndiSSAWchitoliro chachitsulo, komanso mndandanda wathunthu wa zolumikizira mapaipi ndi ma flange. Zogulitsa zake zapadera zimaphatikizaponso zitsulo zapamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zosowa za mapulojekiti osiyanasiyana a mapaipi.
Tikuyembekezera kukhazikitsa ubale wogwirizana nanu ndikupanga tsogolo labwino lomwe aliyense adzapambana.
Chitsulo chosaphika chopangira magawo opanda kanthu ozizira chimachotsedwa mu okosijeni ndipo chiyenera kukwaniritsa zofunikira zinazake zoperekera.
Zofunikira zoyenera za S275J0H ndi S275J2H ndi izi:FF(Chitsulo chophwanyidwa bwino chokhala ndi zinthu zomangira nayitrogeni mu kuchuluka kokwanira kumangirira nayitrogeni yomwe ilipo (monga osachepera 0,020% ya Al yonse kapena 0,015% ya Al yosungunuka)).
Mkhalidwe Wotumizira: Zopindidwa kapena zokhazikika/zokhazikika zopindidwa (N) za zitsulo za JR, J0, J2, ndi K2.
Mapaipi achitsulo ochokera ku EN 10219 akhoza kupangidwa ndi onse awiriERW(kuwotcherera kwa electro resistance) ndiSAW(njira zopangira zolumikizirana ndi arc pansi pamadzi).
Kupanga kwaMachubu a ERWIli ndi ubwino wokhala wachangu komanso wotsika mtengo ndipo nthawi zambiri imasankhidwa pamapulojekiti omwe amafuna kupanga kwakukulu komanso kugwiritsa ntchito ndalama zochepa.

Mapaipi a ERW opangidwa motsatira EN 10219 nthawi zambiri safuna kudula kwa weld mkati.
Izi zili choncho chifukwa machubu a EN 10219 amagwiritsidwa ntchito makamaka pa ntchito za kapangidwe kake, monga zomangamanga ndi zamakina, komwe zofunikira pakuoneka ngati weld nthawi zambiri zimakhala zochepa kuposa zombo zopanikizika kapena mapaipi amphamvu. Chifukwa chake, bola ngati mphamvu ndi umphumphu wa weld zikukwaniritsa zofunikira za muyezo, weld zamkati zitha kugwiritsidwa ntchito popanda kudula kwina.
Palibe chithandizo chotenthetsera chomwe chimachitika pambuyo pake, kupatula kuti weld ikhoza kukhala mu mkhalidwe wowotcherera kapena wokonzedwa ndi kutentha.
Kusanthula kwa Zinthu Zopangidwa ndi Ma Cast (Kuphatikizika kwa Zipangizo Zapadera)
Zonse ziwiri za S275J0H ndi S275J2H zili ndi mtengo wofanana ndi kaboni (CEV) wa 0.40%.
S725J0H ndi S275J2H zokhala ndi CEV yokwanira 0.4% zikuwonetsa kusinthasintha kwabwino kwa kuluka ndi chiopsezo chochepa cha kuuma ndi kusweka panthawi yolukira.
Ikhozanso kuwerengedwa pogwiritsa ntchito njira iyi:
CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15.
Kusanthula kwa Zamalonda (Kuphatikizika kwa Mankhwala a Zamalonda Zomalizidwa)
Pakupanga chitsulo, kapangidwe ka mankhwala kangasinthe pazifukwa zingapo, ndipo kusinthaku kungakhudze mawonekedwe ndi mtundu wa chitsulocho.
Kapangidwe ka mankhwala a chitoliro chachitsulo chomalizidwa komaliza kayenera kutsatira kapangidwe ka mankhwala a choponyeracho ndi kupatuka kwake kololedwa.
Magawo a mphamvu ya makina ndi monga mphamvu ya kukolola, mphamvu yokoka, kutalika, ndi mphamvu ya kukhudza.
Kuchepetsa kupsinjika maganizo pa kutentha kopitilira 580 ℃ kapena kwa ola limodzi kungayambitse kuwonongeka kwa mphamvu ya makina.
Zolemba:
Kuyesa mphamvu sikofunikira pamene makulidwe omwe atchulidwa ndi <6mm.
Kapangidwe ka mphamvu ya machubu abwino a JR ndi J0 sikutsimikiziridwa pokhapokha ngati kwatchulidwa.
