Chitoliro chachitsulo cha ASTM A53
ASTM A53 (ASME A53) chitoliro cha chitsulo cha kaboni ndi chitoliro chomwe chimakwirira chitoliro chachitsulo chakuda komanso choviikidwa mu NPS 1/8″ mpaka NPS 26. amagwiritsidwa ntchito mu nthunzi, madzi, gasi, ndi mizere ya ndege.
Chitoliro cha A53 chimabwera m'mitundu itatu (F, E, S) ndi magiredi awiri (A, B).
A53 Type F imapangidwa ndi ng'anjo yamoto yowotcherera kapena imatha kukhala ndi weld mosalekeza (Giredi A yokha)
A53 Type E ili ndi weld yamagetsi yamagetsi (Makalasi A ndi B)
A53 Type S ndi chitoliro chopanda msoko ndipo chimapezeka m'magiredi A ndi B)
A53 Grade B Seamless ndiye chinthu chathu chopangidwa ndi polar kwambiri pansi pa izi ndipo chitoliro cha A53 nthawi zambiri chimakhala chovomerezeka cha A106 B Chitoliro Chopanda Msokonezo.
