ASTM A789/A789M spesifikasyon kouvri kondisyon estanda pou klas epesè miray nominal, ak tib asye pur pou sèvis ki mande rezistans jeneral korozyon, ak anfaz patikilye sou rezistans nan krak korozyon estrès. Asye sa yo sansib a frajil si yo itilize pou peryòd pwolonje nan tanperati ki wo.
Yo dwe fè analiz chalè ak pwodwi kote asye a dwe konfòme yo ak konpozisyon chimik ki nesesè pou kabòn, Manganèz, fosfò, souf, Silisyòm, nikèl, chromium, molybdène, nitwojèn, kwiv, ak lòt moun.
Tout tib yo dwe founi nan kondisyon chalè-trete yo swivan tanperati a espesifye ak kondisyon trempe. Lè tretman chalè final la nan yon gwo founo kontinyèl, oswa lè chalè chalè -trete kondisyon yo jwenn dirèkteman pa trempe apre cho fòme, kantite tib ki gen menm gwosè ak ki soti nan menm chalè nan yon anpil yo dwe detèmine nan gwosè yo preskri nan tib yo.
Materyèl la dwe konfòme yo ak pwopriyete yo preskri tansyon ak dite. Tès mekanik tankou tès tansyon, tès flaring (pou tib san pwoblèm), tès bride (pou tib soude), tès dite, ak tès ranvèse plat dwe fèt sou tib asye a. Chak tib dwe tou sibi tès elektrik nondestructive oswa tès idrostatik la.
