Chitoliro chachitsulo chosasokonekeraASTM A53, SCH40, Gr.B ndi chitoliro chachitsulo chapamwamba kwambiri chomwe chimagwiritsidwa ntchito kwambiri pamsika, chokhala ndi magwiridwe antchito abwino komanso magawo osiyanasiyana ogwiritsira ntchito. Izi ndi chiyambi cha zabwino za chitoliro chachitsulo ichi:

Zipangizo ndi Zokhazikika
ASTM A53muyezo ndi muyezo wokhwima wa mapaipi achitsulo chosasunthika mumakampani opanga zitsulo aku US, omwe amagwiritsidwa ntchito makamaka pamafuta, gasi wachilengedwe, nthunzi ndi mapaipi ena. Chitoliro chachitsulo ichi chimapangidwa ndi chitsulo cha kaboni kapena chitsulo chotsika cha alloy. Giredi B (Gr.B) ikuwonetsa kuti chitolirocho chili ndi mphamvu zambiri komanso kukana kupanikizika ndipo chimayenera malo opanikizika apakati komanso okwera. SCH40 ikutanthauza muyezo wa makulidwe a khoma la chitoliro, zomwe zimatsimikizira kuti chitolirocho chili ndi kukana dzimbiri kokwanira komanso mphamvu yonyamula kupanikizika.

Njira yopangira ndi khalidwe
Chitoliro chachitsulo ichi chimagwiritsa ntchito ukadaulo wapamwamba wopanga chitoliro chachitsulo chosasunthika kuti chitsimikizire kuti zinthu zili bwino, pamwamba pake pali chitoliro chosalala, palibe zolakwika zowotcherera, komanso kukana kupanikizika bwino komanso kukana dzimbiri. Kudzera mu kuwunika kokhwima kwa khalidwe, chimakwaniritsa zofunikira zaASTM A53muyezo woonetsetsa kuti mphamvu, kuuma, kusinthasintha, ndi kukana dzimbiri kwa chitoliro chilichonse chachitsulo zikugwirizana ndi miyezo yamakampani.

Mafotokozedwe ndi kuchuluka kwa ntchito
Chitoliro chachitsulo chosasunthika chili ndi mitundu yosiyanasiyana, kuphatikizapo mainchesi akunja ofanana kuyambira 1/8" mpaka 30", ndipo makulidwe a khoma amatha kusinthidwa malinga ndi zosowa. Chimagwiritsidwa ntchito kwambiri m'magawo a mafuta, mankhwala, magetsi, zomangamanga zombo, makina, ndi zina zotero, makamaka yoyenera machitidwe a mapaipi omwe amanyamula zinthu zamadzimadzi monga madzi, mafuta, ndi gasi.

Amagwiritsidwa ntchito kwambiri
ASTM A53Chitoliro chachitsulo chosasunthika chingagwiritsidwe ntchito pa mapaipi otumizira mpweya amphamvu kwambiri, nyumba zomangira, mapaipi ophikira boiler, mapaipi otumizira mafuta ndi gasi wachilengedwe, ndi zina zotero, posintha malo osiyanasiyana ogwirira ntchito ovuta, kupereka chitsimikizo chodalirika cha mayendedwe ndi chitetezo.
