Chitoliro chopanda chitsuloChithunzi cha ASTM A53, SCH40, Gr.B ndi chitoliro chachitsulo chapamwamba chomwe chimagwiritsidwa ntchito kwambiri pamsika, chokhala ndi ntchito zabwino komanso ntchito zosiyanasiyana. Zotsatirazi ndi chiyambi cha ubwino wa chitoliro ichi chachitsulo:

Zofunika ndi Standard
Chithunzi cha ASTM A53muyezo ndi mfundo okhwima zitsulo mipope mu US zitsulo makampani, makamaka ntchito mafuta, gasi, nthunzi ndi mapaipi ena. Chitoliro ichi chimapangidwa ndi chitsulo cha carbon kapena low alloy steel. Gulu B (Gr.B) limasonyeza kuti chitoliro chili ndi mphamvu zambiri komanso kukana kupanikizika ndipo ndi yoyenera kwa malo apakati komanso apamwamba. SCH40 imatanthawuza muyezo wa makulidwe a khoma la chitoliro, zomwe zimatsimikizira kuti chitolirocho chili ndi kukana kwa dzimbiri kokwanira komanso mphamvu yonyamula mphamvu.

Kupanga ndondomeko ndi khalidwe
Izi zitsulo chitoliro utenga patsogolo zitsulo zitsulo kupanga luso luso kuonetsetsa khola mankhwala khalidwe, yosalala chitoliro pamwamba, palibe kuwotcherera zilema, ndi kukana kwambiri kuthamanga ndi kukana dzimbiri. Kupyolera mwa kuyang'anitsitsa khalidwe labwino, limakwaniritsa zofunikira zaChithunzi cha ASTM A53muyezo kuonetsetsa kuti mphamvu, kuuma, ductility ndi dzimbiri kukana chitoliro aliyense zitsulo kukumana mfundo makampani.

Mafotokozedwe ndi kuchuluka kwa ntchito
Chitoliro chopanda msoko chili ndi mawonekedwe osiyanasiyana, kuphatikiza ma diameter wamba akunja kuyambira 1/8 "mpaka 30", ndipo makulidwe a khoma amatha kusinthidwa malinga ndi zosowa. Amagwiritsidwa ntchito kwambiri pamafuta, mankhwala, mphamvu yamagetsi, kupanga zombo, makina, ndi zina zambiri, makamaka oyenera pamapaipi omwe amanyamula media zamadzimadzi monga madzi, mafuta, ndi gasi.

Zogwiritsidwa ntchito kwambiri
Chithunzi cha ASTM A53Chitoliro chachitsulo chosasunthika chingagwiritsidwe ntchito pamapaipi opatsirana kwambiri, zomanga nyumba, mapaipi opangira boiler, mapaipi otumizira mafuta ndi gasi, ndi zina zambiri, kusinthira kumadera osiyanasiyana ogwirira ntchito, kupereka magwiridwe antchito odalirika komanso chitetezo.
