Engineering dongosolo replenishment, mankhwala aloyi zitsulo chitoliroA333 GR6, ndondomeko ndi 168.3 * 7.11, ndimpweya zitsulo chitoliro GB/T9948, 20#, ndondomeko ndi 114.3*6.02, etc.

Zotsatirazi zikuwonetsa miyezo ndi zida zomwe ma engineering angakumane nazo:

20 # GB8163 zoyendera madzimadzi opanda zitsulo chitoliro

Kodi chuma cha chitoliro chosasunthika chimatanthauza chiyani? Zomwe zilinso ndi kalasi yomwe timanena nthawi zambiri, monga 20 #, 45 #, yomwe imayimira mankhwala ake ndi makina ake monga mphamvu zolimba, mphamvu zokolola, ndi kukula kwake. Zotsatirazi ndizo zomwe zimagwiritsidwa ntchito popanga zida zachitsulo zopanda msoko, miyeso yopangira ndikugwiritsa ntchito mwachidule ndi wolemba.

1.GB/T8162-2018, Structural msoko zitsulo mapaipi, makamaka ntchito zomangamanga ambiri structural, processing makina, zomangamanga ndi madera ena. Zoyimira: 20 #, 45 #, q345b, 40Cr, 42CrMo, etc.;

2. GB/T8163-2018, chitoliro chopanda chitsulo chosapanga dzimbiri choyendetsa madzimadzi, chomwe chimagwiritsidwa ntchito kwambiri pakupanga mapaipi otsika kwambiri. Zoyimira: 20 #, q345b;
45 # GB8162 structural zitsulo chitoliro

3.GB/T3087-2017, mapaipi achitsulo otsika ndi apakatikati, omwe amagwiritsidwa ntchito popanga zida zosiyanasiyana zamapaipi otentha kwambiri, mapaipi amadzi otentha a boilers otsika ndi apakatikati, mapaipi otentha kwambiri ndi mapaipi anjerwa aarch opangira ma boilers a locomotive. Zoyimira: 10 #, 20 #, Q355B;
GB5310 mkulu kuthamanga kukatentha chubu, zakuthupi 12Cr1MovG

4. GB/T5310-2017, mapaipi achitsulo osasunthika a ma boilers othamanga kwambiri, omwe amagwiritsidwa ntchito kwambiri pakuwotcha pamwamba pa ma boiler amadzi okhala ndi kuthamanga kwambiri komanso pamwamba. Pali carbon steel, aloyi zitsulo ndi zitsulo zosapanga dzimbiri mipope zitsulo zosagwira msoko. Zoyimira: 20G, 15CrMoG, 12Cr1MoVG, etc.;

5. GB/T6479-2018, mapaipi achitsulo osasunthika osasunthika opangira zida za feteleza, zomwe zimagwiritsidwa ntchito kwambiri pazida zamankhwala ndi mapaipi okhala ndi kutentha kwa -40 ~ 400 ° C ndi kukakamiza kwa 10 ~ 30Ma. Pali mpweya structural zitsulo ndi aloyi zitsulo seamless zitsulo mapaipi. Zoyimira: q345a-bcde, 20 #, 10mowvnb, 15CrMo;

6. GB/T9948-2013, mapaipi achitsulo osasunthika ophwanya mafuta, makamaka omwe amagwiritsidwa ntchito ngati machubu a ng'anjo, zotenthetsera kutentha ndi mapaipi m'malo opangira mafuta. Zoyimira: 10 #, 20 #, Q345, 15CrMo;
