Kodi JIS G 3454 ndi chiyani?

JIS G 3454ndi muyezo wa mafakitale aku Japan wa mapaipi achitsulo cha kaboni pamakina opanikizika okhala ndi kutentha kwakukulu kogwira ntchito kwa 350°C. Muyezowu uli ndi mitundu iwiri:STPG 370ndiSTPG 410Imagwira ntchito pa mapaipi otetezedwa ndi magetsi (ERW) kapena mapaipi osalumikizana okhala ndi mainchesi apakati pa 10.5 mm mpaka 660.4 mm (monga 6A mpaka 650A, kapena 1/8B mpaka 26B).

Timapatsa

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 komanso zitsulo zosapanga dzimbiri zopangidwa ndi austenitic, zopangidwa kuti zikwaniritse zosowa za mapulojekiti osiyanasiyana a mapaipi.

Chonde titumizireni uthenga, tidzakupatsani mapaipi achitsulo abwino kwambiri komanso ogwira ntchito mwaukadaulo komanso moyenera. Botop ikuyembekezera kukuthandizani.
