JIS G 3454 kulolerana kwa mainchesi akunja, makulidwe a khoma, eccentricity, ndi kutalika kwake kudzakwaniritsa izi.
Chiyambireni kukhazikitsidwa mu 2014, Botop Steel yakhala ikugulitsa chitoliro chachitsulo cha carbon ku Northern China, chomwe chimadziwika ndi ntchito zabwino kwambiri, zinthu zamtengo wapatali, komanso zothetsera mavuto.
Kampaniyi imapereka mapaipi osiyanasiyana a zitsulo za carbon ndi zinthu zomwe zimagwirizana nazo, kuphatikizapo zopanda msoko, ERW, LSAW, ndi chitoliro chachitsulo cha SSAW, komanso mzere wathunthu wazitsulo 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.
Chonde titumizireni, tidzakupatsirani mapaipi apamwamba kwambiri, okhazikika achitsulo omwe ali ndi ntchito yabwino komanso yothandiza.Botop akuyembekezera kukutumikirani.
