    Kampani yathu imatumiza mapaipi achitsulo,China Seamless Pipe, China kapangidwe mapaipi, Chitoliro chachitsulo chosasinthika, mapangidwe mapaipi. Q345B zakuthupi ndi mtundu wa structural zitsulo chitoliro.

    Q345 ndi mtundu wa zinthu zachitsulo. Ndi carbon alloy steel (c <0.2%) ndi ntchito yabwino yonse, ntchito yabwino yotsika kutentha, ntchito yozizira yopondaponda, kuwotcherera ndi machinability. Amagwiritsidwa ntchito kwambiri m'milatho, magalimoto, zombo, nyumba, zotengera zokakamiza, etc. Q imayimira zokolola za nkhaniyi, ndipo 345 yotsiriza imatanthawuza mtengo wamtengo wapatali wa zinthuzi, zomwe zili pafupi ndi 345MPa. Ndipo makulidwe a zinthuzo akamakula, zokolola zake zimachepa.

    Q345 Q345

    Mphamvu zokolola:≤16 mm:kuposa 345, 16-40mm: kuposa 335, 40-63mm: kuposa 325, 63-80mm: kuposa 315, 80-100m: kuposa 305, 100-150mm: kuposa 285, 150-200mm: kuposa 275.

    Mphamvu yolimba: 450-630.

    Kutalika: kuposa 17.

    Kuyesa kwamphamvu: Kutentha kwa mayeso: 20°C: kuposa 34.

    1. Chitoliro chachitsulo chosasunthika cha kapangidwe kake (GB/T8162-2008) ndiChitoliro chachitsulo chosasinthikakwa kapangidwe kake ndi kapangidwe ka makina.

    2. Chitoliro chosasunthika chachitsulo choyendetsa madzimadzi (GB/T8163-2008) ndi chitoliro chachitsulo chosasunthika chomwe chimagwiritsidwa ntchito kunyamula madzi, mafuta, gasi ndi madzi ena.

    3. Mipope yachitsulo yopanda malire ya ma boilers otsika ndi apakatikati (GB3087-2008) ndi mapaipi apamwamba kwambiri a carbon structural steel heat mapaipi omwe amagwiritsidwa ntchito popanga mapaipi otentha kwambiri, mapaipi otentha amadzi opangira ma boiler otsika ndi apakatikati amitundu yosiyanasiyana, mapaipi otenthetsera kwambiri komanso mipope ya njerwa yopangira ma boilers a locomotive. Machubu opanda zitsulo opiringizika komanso ozizira.

    4. Mipope yachitsulo yosasunthika yamagetsi othamanga kwambiri (GB5310-2008) ndi zitsulo zamtengo wapatali za carbon, alloy zitsulo ndi zitsulo zosapanga dzimbiri zosapangana ndi zitsulo zosapanga dzimbiri zopangira kutentha pamwamba pa machubu amadzi otentha ndi kuthamanga kwambiri ndi pamwamba.
