Muyezo wa EN 10219 umakwirira mitundu ingapo yazitsulo zachitsulo zosanjikizana, kuphatikiza kuzungulira, masikweya, amakona anayi, ndi oval, kuti zigwirizane ndi zofunikira pakugwiritsa ntchito.
Botop Steelimakhazikika popereka machubu achitsulo ozungulira ozungulira m'miyeso ndi njira zosiyanasiyana kuti agwirizane ndi ntchito zosiyanasiyana zamakampani, kuwonetsetsa kuti zosowa za makasitomala athu zitha kukwaniritsidwa.
Kuyambira pomwe idakhazikitsidwa mu 2014,Botop Steelwakhala katundu kutsogolera mpweya zitsulo chitoliro ku Northern China, kudziwika ndi utumiki kwambiri, mankhwala apamwamba, ndi mayankho mabuku.
Kampaniyo imapereka mapaipi osiyanasiyana azitsulo za kaboni ndi zinthu zina, kuphatikizaSMLS, ERW, Mtengo wa LSAW,ndiChithunzi cha SSAWchitsulo chitoliro, komanso mzere wathunthu wa zida za chitoliro ndi flanges.Zopangira zake zapadera zimaphatikizanso ma alloys apamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zofunikira zama projekiti osiyanasiyana a mapaipi.
Tikuyembekezera kukhazikitsa ubale wogwirizana ndi inu ndikupanga tsogolo lopambana-kupambana limodzi.
Chitsulo chaiwisi chopangira zigawo za dzenje zozizira chimakhala ndi deoxidized ndipo chiyenera kukwaniritsa zofunikira zoperekera.
Zofunikira pa S275J0H ndi S275J2H ndiFF(Kupha kwathunthu chitsulo chokhala ndi nayitrogeni zomangira zinthu mu ndalama zokwanira kumanga asafe (mwachitsanzo min.0,020 % okwana Al kapena 0,015 % sungunuka Al)).
Kutumiza: Kukulungidwa kapena kukhazikika / kukulunga bwino (N) kwa zitsulo za JR, J0, J2, ndi K2.
Mapaipi achitsulo kupita ku EN 10219 amatha kupangidwa ndi onse awiriERW( electro resistance kuwotcherera ) ndiSAW( submerged arc welding ) njira zopangira.
Kupanga kwaZithunzi za ERWali ndi mwayi wokhala wothamanga komanso wotsika mtengo kwambiri ndipo nthawi zambiri amasankhidwa kumapulojekiti omwe amafunikira kupanga kwakukulu komanso kutsika mtengo kwambiri.
ERWmachubu nthawi zambiri amagwiritsidwa ntchito kupanga ma diameter ang'onoang'ono komanso makulidwe a khoma, pomweSAWmachubu ndi oyenera ma diameter akulu ndi makoma okhuthala.Chonde sankhani chitoliro choyenera chachitsulo cha polojekiti yanu.
Mapaipi a ERW opangidwa molingana ndi EN 10219 nthawi zambiri safuna kudula mkati.
Izi ndichifukwa choti machubu a EN 10219 amagwiritsidwa ntchito makamaka pamapangidwe, monga zomangamanga ndi uinjiniya wamakina, pomwe zofunikira pakuwoneka bwino nthawi zambiri zimakhala zolimba kuposa zotengera zokakamiza kapena mapaipi oponderezedwa kwambiri.Choncho, malinga ngati mphamvu ndi kukhulupirika kwa weld zikukwaniritsa zofunikira za muyezo, welds mkati angagwiritsidwe ntchito popanda yokonza zina.
Palibe chithandizo chotsatira cha kutentha chomwe chimachitidwa, kupatula kuti weld akhoza kukhala wotenthedwa kapena wotenthedwa.
Kuwunika kwa Cast (Chemical Composition of Raw Raw)
Onse S275J0H ndi S275J2H ali ndi mtengo wofanana wa kaboni (CEV) wa 0.40%.

Itha kuwerengedwanso pogwiritsa ntchito njira iyi:
CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15.
Kusanthula Kwazinthu (Kupanga Kwama Chemical kwa Zinthu Zomaliza)
Pakupanga zitsulo, mankhwala amatha kusintha pazifukwa zingapo, ndipo kusintha kumeneku kungakhudze katundu ndi khalidwe lachitsulo.
Yomaliza yomalizidwa zitsulo chitoliro mankhwala zikuchokera ayenera kutsatira mankhwala zikuchokera kuponya ndi kupatuka wake chovomerezeka.
