BS EN 10210 S355J0H, chitsulo nambala 1.0547, ndi cha gawo la chitsulo chopangidwa ndi dzenje lotentha ndipo chitoliro chachitsulo chopanda msoko kapena cholumikizidwa, chomwe chimagwiritsidwa ntchito kwambiri m'nyumba zomwe zimafuna mphamvu zambiri komanso kulimba bwino, monga mafelemu akuluakulu omangira ndi milatho.
Zipangizo za S355J0H zili ndi mphamvu yamakina yoti mphamvu yocheperako yotulutsa ndi 355MPa pamene makulidwe a khoma sapitirira 16 mm ndipo amakwaniritsa mphamvu yocheperako yokhudza 27J pa 0℃.
BS EN 10210 ili ndi mitundu yosiyanasiyana ya mawonekedwe, monga ozungulira, apakati, amakona anayi, kapena ozungulira, Botop Steel imagwira ntchito kwambiri popanga machubu achitsulo ozungulira amitundu yosiyanasiyana, kukupatsani zida zapamwamba komanso zovomerezeka zachitsulo zomwe zimagulitsidwa mwachindunji ku fakitale komanso mtengo wopikisana.
Chidziwitso: Zofunikira zonse zomwe zili mu chikalatachi zikugwiranso ntchito ku EN 10210.
Kukhuthala kwa khoma ≤120mm.
Zozungulira (HFCHS): Ma diameter akunja mpaka 2500 mm;
Sikweya (HFRHS): Miyeso yakunja mpaka 800 mm x 800 mm;

Mawonekedwe a zinthu mu BS EN 10210 amadalira mphamvu zawo zochepa zokolola pa makulidwe a khoma a 16mm ndi makhalidwe ake okhudzana ndi kutentha kwina. Mphamvu yokolola, mphamvu yokoka, ndi kutalika kwa BS EN 10210 S355J0H zimachepa pamene makulidwe a khoma akuwonjezeka.
BS EN 10210 imalola kupanga pogwiritsa ntchito njira zosiyanasiyana zopangira, zomwe nthawi zambiri zimaphatikizapo njira zolumikizirana zopanda msoko, LSAW, SSAW, ndi ERW.
Pansipa pali mitundu yosiyanasiyana ya zinthu zomwe zimagwiritsidwa ntchito popanga zinthu.
Kuchokera kufananiza komwe kwatchulidwa pamwambapa, zitha kuwoneka kuti chitoliro chachitsulo chosasunthika chili ndi ubwino wofunikira popanga chitoliro chachitsulo chokhala ndi makoma okhuthala, makamaka chitoliro chachitsulo chokhala ndi makoma okhuthala ang'onoang'ono, koma kukula kwake kudzakhala kochepa. Ngati mukufuna kupanga mapaipi achitsulo okhala ndi mainchesi opitilira 660mm, zidzakhala zovuta kwambiri.
Chitoliro Chakuda
Izi zikutanthauza chitoliro chachitsulo chopanda chithandizo chilichonse cha pamwamba.
Zophimba Zoteteza Zakanthawi
Pofuna kupewa dzimbiri la mapaipi achitsulo panthawi yosungira, kunyamula, kapena kuyika, njira yodziwika bwino ndiyo kupaka pamwamba pa chitolirocho ndi utoto kapena vanishi.
Chophimba Choletsa Kutupa
Pali mitundu yambiri ya zophimba zotsutsana ndi dzimbiri, kuphatikizapo utoto, FBE,3LPE, ndi galvanized. Mtundu uliwonse wa chophimba uli ndi makhalidwe apadera komanso malo oyenera. Kutupa ndi dzimbiri zitha kupewedwa bwino poika chophimba choyenera choletsa dzimbiri pamalo achitsulo.

Kuyambira pomwe idakhazikitsidwa mu 2014, Botop Steel yakhala 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, kuphatikizapo mapaipi achitsulo opanda msoko, ERW, LSAW, ndi SSAW, 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.
Zinthu zina zokhudzana nazo:
Chitoliro chachitsulo cha BS EN10210 S275J0H LSAW(JCOE)
Chitoliro chachitsulo cha EN10210 S355J2H cha Kapangidwe ka ERW
Lumikizanani nafe kuti mupeze mtengo waulere komanso upangiri pa ntchito yanu.
