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 1 ukhoza kugawidwa mu 1a ndi 1b.
Type 1a (AWHR): "monga-welded" kuchokera kuzitsulo zotentha (zokhala ndi sikelo ya mphero).
Chitoliro ichi chimawotchedwa mwachindunji kuchokera ku zitsulo zotentha ndi zitsulo zachitsulo (mphero) zomwe zimapangidwira panthawi yogubuduza.Chitoliro chamtunduwu nthawi zambiri chimagwiritsidwa ntchito pomwe umphumphu wa pamwamba suli wofunikira chifukwa pamwamba pamakhala sikelo ya mphero.
Type 1b (AWPO): "monga-welded" kuchokera ku chitsulo chosungunuka ndi mafuta odzola (chigayo chachotsedwa).
Chitoliro ichi chimawotchedwa kuchokera ku zitsulo zotentha zotentha zomwe zasankhidwa ndi kuzipaka mafuta ndipo zimadziwika ndi kuchotsedwa kwa sikelo ya mphero.Kuthira mafuta a pickling ndi kudzola mafuta sikumangochotsa makutidwe ndi okosijeni komanso kumapereka chitetezo cha dzimbiri ndi mafuta panthawi yokonza, zomwe zimapangitsa kuti chitolirochi chikhale choyenera kugwiritsa ntchito zomwe zimafuna malo oyeretsera kapena zothina pang'ono.

Wotentha-wodzigudubuza
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.
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.
