Chiyambi cha zitsulo zapamwamba kwambiri za carbon structural steel ndi alloy structural chitsulo mapaipi opanda zitsulo zopopera kwambiri komanso pamwamba pa mapaipi a boilers.

GB/T5310mapaipi achitsulo osasunthika ndi zinthu zapamwamba kwambiri zopangidwira kupanikizika kwambiri komanso kupitilira mapaipi otenthetsera nthunzi. Amapangidwa ndi chitsulo chamtengo wapatali cha carbon structural steel ndi alloy structural steel zitsulo kuti zitsimikizire kuti zimagwira ntchito bwino komanso zimakhala zodalirika m'malo otentha kwambiri komanso opanikizika kwambiri. Chitoliro chachitsulo chopanda msokochi chimagwiritsidwa ntchito kwambiri popanga mapaipi otenthetsera ndi kutentha, kupereka chitsimikizo cholimba cha kupanga mafakitale.

Maphunziro apamwamba

GB/T5310mapaipi achitsulo osasunthika amapangidwa makamaka ndi Cr-Mo alloy ndi Mn alloy, ndipo magiredi akuluakulu amaphatikiza.20G pa, 20Mg, 20MoG, 12CrMoG, ndi zina zotero. Zidazi zimakhala ndi mphamvu zabwino kwambiri za kutentha kwapamwamba komanso kukana kwa okosijeni, ndipo zingagwiritsidwe ntchito kwa nthawi yaitali m'malo ovuta kugwira ntchito popanda kulephera. Mwa iwo:

20G pa: Chitsulo chapamwamba cha carbon structural chokhala ndi pulasitiki wabwino komanso wolimba, chomwe chimagwiritsidwa ntchito kwambiri pamapaipi apakati komanso otsika kwambiri.
20Mg: Kuwonjezera manganese ku 20G kumawonjezera mphamvu ndi kuuma kwa zinthuzo, zoyenera mapaipi apakati komanso othamanga kwambiri.
20MoG: Molybdenum imawonjezedwa ku 20G, yomwe imathandizira kwambiri kukana kutentha ndi kukwawa, ndipo ndiyoyenera mapaipi opopera kwambiri.
12CrMoG: Chitsulo chopangidwa ndi aloyi chokhala ndi chromium ndi molybdenum, chokhala ndi kukana kwa okosijeni kwapamwamba kwambiri komanso kutentha kwambiri, koyenera mapaipi otenthetsera kwambiri.
Aloyi structural zitsulo makalasi

The aloyi structural zitsulo magiredi a GB/T5310 muyezo msoko zitsulo mapaipi amaphatikizanso 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, ndi zina zotero. :

15MoG ndi 20MoG: Kuwonjezera kuchuluka koyenera kwa molybdenum kumathandizira kwambiri kutentha kwapamwamba komanso kukana kwa dzimbiri kwa chitoliro chachitsulo.
12CrMoG ndi15CrMoG: Kuwonjezera chromium ndi molybdenum kumawonjezera kukana makutidwe ndi okosijeni ndi mkulu-kutentha mphamvu ya chitoliro zitsulo, ndi oyenera chilengedwe ndi kutentha kwambiri ndi mavuto.
12Cr2MoG ndi 12CrMoVG: Mapangidwe a aloyi amakonzedwanso, ndi mphamvu zonse za kutentha komanso kukana kwa okosijeni, ndipo amachita bwino kwambiri m'malo ovuta kwambiri.
Mapulogalamu
Mapaipi achitsulo osasunthika a GB/T5310 amagwiritsidwa ntchito kwambiri m'mapaipi otenthetsera ndi zotenthetsera kutentha, makamaka pazida zotentha kwambiri komanso zothamanga kwambiri monga ma boilers apamagetsi, ma boiler aku mafakitale, ndi zotenthetsera zinyalala. Mipope yachitsulo yopanda msokoyi imatha kupirira zovuta zogwira ntchito kwambiri komanso kutentha, kuonetsetsa kuti zikuyenda bwino komanso moyo wautali wa ma boilers ndi osinthanitsa kutentha. Kuphatikiza apo, mapaipi achitsulowa amagwiritsidwanso ntchito pazida zosinthira kutentha m'makampani a petrochemical, kukulitsa madera awo ogwiritsira ntchito.
Chidule
Mapaipi achitsulo a GB/T5310 achitsulo osasunthika akhala chinthu chomwe chimakondedwa kwambiri pakuponderezedwa kwambiri komanso pamwamba pa mapaipi otenthetsera nthunzi chifukwa cha zinthu zake zabwino kwambiri komanso ntchito zosiyanasiyana. Kaya ndi 20G, 20Mg, 20MoG, 12CrMoG ndi zipangizo zina, kapena 15MoG, 20MoG, 12CrMoG ndi magiredi ena a aloyi achitsulo, onse amasonyeza kukana kwambiri kutentha kwa okosijeni ndi kutentha kwakukulu, kupereka zitsimikizo zodalirika za ntchito yotetezeka komanso yogwira ntchito. zida zamakampani.
