Chitoliro chachitsulo cha carbon, chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale, chimagwira ntchito yofunika kwambiri m'mafakitale monga mafuta, uinjiniya wamankhwala, ndi zomangamanga. Mapaipi wamba achitsulo cha kaboni amagawidwa m'mitundu iwiri:Chitoliro chachitsulo chosasinthikandiwelded zitsulo chitoliro.
Pankhani ya kupanga ndi kapangidwe kake, chitoliro chachitsulo chosasunthika chimapangidwa kudzera pakugubuduza kophatikizika kapena kutulutsa, popanda seams welded. Imakhala ndi mphamvu zambiri komanso kulimba, imatha kupirira kupsinjika ndi kutentha kwambiri, ndipo ndiyoyenera kugwiritsa ntchito zomwe zimafunikira chitetezo cholimba cha chitoliro.
Chitoliro chachitsulo chowotcherera, komano, chimapangidwa ndi kukulunga ndi kuwotcherera mbale zachitsulo, zokhala ndi chowotcherera chimodzi kapena zingapo. Ngakhale kuti izi zimapereka mphamvu zambiri zopangira komanso zotsika mtengo, ntchito yake pansi pa kupanikizika kwakukulu ndi malo ovuta kwambiri ndi otsika pang'ono poyerekeza ndi chitoliro chopanda msoko.
Kwa chitoliro chachitsulo chosasinthika, Q235 ndi A36 ndi sukulu zodziwika bwino. Q235 zitsulo chitoliro ndi ambiri ntchito mpweya structural zitsulo kalasi ku China. Ndi mphamvu zokolola za 235 MPa, zimapereka weldability kwambiri ndi ductility pa mtengo angakwanitse. Amagwiritsidwa ntchito kwambiri pomanga chithandizo chomangira, mapaipi amadzimadzi otsika kwambiri, ndi ntchito zina, monga mapaipi operekera madzi okhala ndi nyumba ndi chitsulo chomanga nyumba za fakitale wamba.
A36 carbon steel pipendi US standard grade. Mphamvu zake zokolola ndizofanana ndi Q235, koma zimapereka mphamvu zochulukirapo komanso kulimba kwamphamvu. Amagwiritsidwa ntchito kwambiri m'mapaipi otsika kwambiri popanga makina ndi kupanga mafuta, monga kukonza magawo ang'onoang'ono amagetsi ndi mapaipi amafuta otsika kwambiri m'minda yamafuta.
Kwa welded steel pipe,Q235 welded chitsulo chitoliroilinso kalasi yotchuka. Chifukwa cha mtengo wake wotsika komanso magwiridwe antchito abwino kwambiri amawotcherera, amagwiritsidwa ntchito nthawi zambiri potumiza gasi mumzinda komanso ma projekiti opatsira madzi otsika. Komano, chitoliro chowotcherera cha A36 chimagwiritsidwa ntchito kwambiri m'mapaipi ang'onoang'ono amakampani omwe ali ndi zofunikira zina zamphamvu, monga mapaipi otengera zinthu zotsika zamagetsi m'mafakitale ang'onoang'ono.
| Kufananiza Makulidwe | Q235 Chitoliro chachitsulo | Chitoliro chachitsulo cha carbon A36 |
| Standard System | China National Standard (GB/T 700-2006 "Carbon Structural Steel") | American Society for Testing and Equipment (ASTM A36/A36M-22 "Carbon Steel Plate, Shapes, and Bars for Structural Prate") |
| Mphamvu Zokolola (Zochepa) | 235 MPa (kukhuthala ≤ 16 mm) | 250 MPa (pamtundu wonse wa makulidwe) |

| Zofunikira Zolimbitsa Thupi | Mayeso a -40 ° C amafunikira pamagiredi ena okha (mwachitsanzo, Q235D); palibe chofunikira chofunikira pamakalasi wamba. | Zofunikira: -18 ° C kuyezetsa zotsatira (zotsatira zochepa); kulimba kwa kutentha pang'ono kuposa magiredi wamba a Q235 |
| Zochitika Zazikulu Zogwiritsira Ntchito | Zomangamanga (zomangamanga zachitsulo, zothandizira), mapaipi ocheperako amadzi / gasi, ndi zida zamakina | Kupanga makina (zigawo zing'onozing'ono ndi zapakatikati), mapaipi amafuta otsika kwambiri, mapaipi amadzimadzi amafuta ochepa |
Ponseponse, mapaipi achitsulo osasunthika komanso owotcherera aliyense ali ndi zabwino zake. Pogula, makasitomala akuyenera kuganizira za kukakamizidwa ndi kutentha kwa pulogalamuyo, komanso bajeti yawo, ndikusankha giredi yoyenera, monga Q235 kapena A36, kuti awonetsetse kuti ntchitoyo ndi yabwino komanso chitetezo.
