ASTM A513 chitsulondi chitoliro chachitsulo cha carbon ndi alloy ndi chubu chopangidwa kuchokera ku zitsulo zotentha kapena zozizira ngati zopangira zopangira zowotcherera (RW), zomwe zimagwiritsidwa ntchito kwambiri mumitundu yonse yamakina.
Mtundu 5Muyeso wa ASTM A513 umatanthawuzaDrawn Over Mandrel (DOM)chubu.
Machubu a DOM amapangidwa poyamba kupanga chubu chowotcherera kenako kuziziritsa ndikuchijambula pa ma dies ndi pamwamba pa mandrels kuti atsirize kuyandikira motalikirana komanso kutsirizika kwapamwamba poyerekeza ndi mitundu ina ya machubu owotcherera.

Mitundu ya ASTM A513 imasiyanitsidwa pazikhalidwe zosiyanasiyana kapena njira za chitoliro chachitsulo.
ASTM A513 yozungulira chubu mtundu 5 magiredi wamba ndi awa:

Chitsulo chotentha kapena chozizira
Zopangira zopangira Zitsulo Zotentha kapena Zozizira zimatha kupangidwa ndi njira iliyonse.
Chitsulo Choyaka Chotentha: Popanga, zitsulo zotentha zimatenthedwa poyamba kutentha kwambiri, zomwe zimalola kuti zitsulo zizikulungidwa mu pulasitiki, zomwe zimapangitsa kuti zikhale zosavuta kusintha mawonekedwe ndi kukula kwake.Pamapeto pa kugudubuza kotentha, zinthuzo nthawi zambiri zimakhala zowonongeka komanso zowonongeka.
Chitsulo Chozizira Chozizira: Chitsulo chozizira chimakulungidwa mowonjezereka zinthu zitakhazikika kuti zikwaniritse kukula ndi mawonekedwe omwe mukufuna.Njirayi nthawi zambiri imachitika kutentha kwa chipinda ndipo imabweretsa chitsulo chokhala ndipamwamba komanso miyeso yolondola kwambiri.
Machubu amapangidwa ndi aelectric-resistance-welded (ERW)ndondomeko.
ERW chitoliro ndi njira yopangira chowotcherera pokulunga zitsulo zachitsulo mu silinda ndikugwiritsa ntchito kukana ndi kukakamiza kutalika kwake.
Chitsulo chidzagwirizana ndi zofunikira za mankhwala zomwe zafotokozedwa mu Table 1 kapena Table 2.
