A270 Austenitic Nerjaveèi asye sanitè tib

A270 espesifye ke tib soude yo dwe fabrike lè l sèvi avèk yon pwosesis soude otomatik epi ke pa gen okenn metal filler dwe ajoute pandan pwosesis la soude. Gwo tib ki te travay frèt yo dwe travay frèt sou tib soude pou diminye miray la ak epesè soude pa mwens pase 35 pousan anvan recuit final la. Pa gen okenn filet dwe itilize nan soude. Tout materyèl yo dwe founi nan kondisyon chalè-trete. Yon seksyon nan stock woule plat oswa yon tib dwe analize chimikman pou chak tretman chalè. Chak tib dwe sibi tès mekanik tankou tès ranvèse plat, tès presyon idrostatik oswa tès elektrik ki pa destriktif. Fini sifas sa yo ka espesifye: fini moulen, fini sifas mekanikman poli, No 80 fini, No 120 fini, No 180 fini, No 240 fini, electropolished fini, ak maksimòm brutality mwayèn sifas fini. Polisaj Longitudinal yo ta dwe fèt sou sifas enteryè a sèlman, pandan y ap polisaj sikonferansyèl yo ta dwe fèt sou sifas enteryè a, sifas ekstèn lan oswa toude.
