Chitoliro cha ASTM A53 ndi chopanda msoko komanso chowotcherera cha carbon chitsulo chitoliro chomwe chimagwiritsidwa ntchito kunyamula gasi, madzi, ndi mafuta pamagetsi apamwamba komanso kutentha kwambiri.Mapaipiwa amadziwika chifukwa cha mphamvu zake zapadera komanso kukhalitsa, zomwe zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo ovuta komanso ovuta.Miyezo yokhazikika yopanga yotchulidwa muChithunzi cha ASTM A53onetsetsani kuti mapaipi alibe chilema komanso kukula kwake ndi magwiridwe antchito kuti azitha kusuntha bwino, odalirika.
Komano, machubu otenthetsera a ASTM A192, mbali ina yake, amapangidwira kuti azigwiritsidwa ntchito m'ma boiler othamanga kwambiri, osinthanitsa kutentha, ndi ma condensers.Mipope yachitsulo ya kaboni yopanda msoko imakhala ndi matenthedwe abwino kwambiri ndipo imatha kupirira kutentha kwambiri komanso kupanikizika.Zomwe zafotokozedwa mu ASTM A192 zimawonetsetsa kuti machubu amatha kusamutsa kutentha komanso kukana dzimbiri, kuwonetsetsa kuti makina otenthetsera akuyenda bwino komanso otetezeka.
