Njengoko kuchaziwe kwicandelo elingasentla, ukuba le mibhobho isetyenziswa kwiindawo apho ubushushu buphantsi kakhulu, isetyenziswa kumashishini amakhulu e-ayisikrimu, amashishini amachiza kunye nezinye iindawo ezinjalo. Zisetyenziswa njengemibhobho yothutho kwaye zihlelwe ngokwamanqanaba ahlukeneyo. Ukuhlelwa kwamanqanaba ale mibhobho kwenziwa kwizinto ezahlukeneyo ezifana nokuxhathisa ubushushu, amandla okuqina, amandla okukhupha kunye nokwakheka kweekhemikhali. Imibhobho ye-ASTM A333 ifakwe kumabakala alithoba awohlukeneyo atyunjwe ngala manani alandelayo:1,3,4,6.7,8,9,10, kunye ne-11.

Umgangatho we-ASTM A333 ugubungela udonga olungenamthungo kunye nekhabhoni edityanisiweyo kunye nombhobho wentsimbi wealloyi olungiselelwe ukusetyenziswa kumaqondo obushushu aphantsi. I-ASTM A333 i-alloy pipe iya kwenziwa yinkqubo engenamthungo okanye ye-welding kunye nokongezwa kwentsimbi yokuzalisa kwi-welding operation. Yonke imibhobho engenamthungo kunye ne-welded iya kunyangwa ukulawula ubume bayo obuncinci. Uvavanyo lwe-tensile, iimvavanyo zempembelelo, iimvavanyo ze-hydrostatic, kunye novavanyo olungonakaliyo lombane luya kwenziwa ngokuhambelana neemfuno ezichaziweyo. Ezinye iisayizi zeemveliso zisenokungafumaneki phantsi kolu balulo ngenxa yokuba ubukhulu bodonga olunzima lunefuthe elibi kwiipropati zempembelelo zobushushu obuphantsi.
Ukuveliswa kombhobho wensimbi we-ASTM A333 kubandakanya uthotho lweziphene ezibonakalayo zomphezulu ukuze kuqinisekiswe ukuba zenziwe ngokufanelekileyo. Umbhobho wentsimbi we-ASTM A333 uya kuba phantsi kokwaliwa ukuba ukungafezeki komphezulu okwamkelekileyo akusasazwanga, kodwa kuvele kwindawo enkulu ngaphezu koko kuthathwa njengokugqitywa okufana nomsebenzi. Umbhobho ogqityiweyo uya kuba ngqo ngokufanelekileyo.
