Njengoko bekutshiwo kwicandelo elingasentla, ukuba le mibhobho isetyenziswa kwiindawo apho ubushushu buphantsi kakhulu, isetyenziswa kwimizi-mveliso emikhulu ye-ayisikhrim, kwimizi-mveliso yeekhemikhali nakwezinye iindawo ezinjalo. Isetyenziswa njengemibhobho yokuthutha kwaye yahlulwe ngokwamanqanaba ahlukeneyo. Ukwahlulwahlulwa kwamanqanaba ale mibhobho kwenziwa kwiimeko ezahlukeneyo ezifana nokumelana nobushushu, amandla okutsalwa, amandla okukhupha kunye nokwakheka kweekhemikhali. Imibhobho ye-ASTM A333 ifakwe kwiiklasi ezilithoba ezahlukeneyo ezichazwe ngala manani alandelayo: 1,3,4,6.7,8,9,10, kunye ne-11.

Umgangatho we-ASTM A333 ugubungela umbhobho wentsimbi ye-carbon kunye ne-alloy engenamthungo eludongeni eyenzelwe ukusetyenziswa kumaqondo obushushu aphantsi. Umbhobho we-ASTM A333 kufuneka wenziwe ngenkqubo engenamthungo okanye yokudibanisa ngokongeza isinyithi esingenamthungo kumsebenzi wokudibanisa. Zonke iipayipi ezingenamthungo nezidibeneyo kufuneka ziphathwe ukulawula isakhiwo sazo. Uvavanyo lokuxinana, uvavanyo lwempembelelo, uvavanyo lwe-hydrostatic, kunye novavanyo lombane olungatshabalalisiyo kufuneka lwenziwe ngokuhambelana neemfuno ezichaziweyo. Ezinye iisayizi zemveliso zisenokungafumaneki phantsi kwale nkcazo kuba ubukhulu bodonga obunzima bunempembelelo embi kwiimpawu zempembelelo eziphantsi kobushushu.
Imveliso yepayipi yentsimbi ye-ASTM A333 ibandakanya uthotho lweziphene ezibonakalayo kumphezulu ukuqinisekisa ukuba zenziwe ngokufanelekileyo. Ipayipi yentsimbi ye-ASTM A333 iya kwaliwa ukuba iziphene zomphezulu ezamkelekileyo azisasazekanga, kodwa zibonakala kwindawo enkulu ngaphezu koko kuthathwa njengokugqitywa okufana nomsebenzi. Ipayipi egqityiweyo mayithe tye ngokufanelekileyo.
